The Significance of the North Amrican Arctic, The North Aserican Arctis and Subarctic stand now in much the sae relation to tin rest of the continent as did the far West & century ego. It is a vast frontier little known ada&I most entirely undeveloped. Although the transportation can still be done only at appreciable cost, the North has recently become accessible by means of long range aircraft and the resources of its lands and seas, particularly its mineral wealth, hold promise of eenanie benefits for the entire continent. In addition this area, covering all Alaska and Greenland and eighty percent of Canada, has became within the past few decades an internationally significant region. There is in this tation a challenge to modern science. for here is the opportunity, perhaps for the first time, to pro. vide a scientific basis for te orderly levelopment of a new land This region Is daily increasing in importance for goverment awl industry. For a scientist, there is the unexcelled opportunity offered in the Far North to add signifisant data to mants Enwledge of his environent and himself, This area constitutes a huge laboratory, a natural experimental setup not to be matched in temperate sons The atremes of temperature, the perennially frowan ground; the alternating periods of constant daylight and darkness, the remnants of glaciation, the Northern ights the biological adaption of plants and animals and the meteorology 2 of the region as the weather4eternining faetor of the world are features inviting alike to studies in the natural, bioleo. gleal and social sciences. Strengthened by the present day military considerations, Arc meteorology is a very powrful factor in the existtee and development of the sottlements. The ilitary forces eon-. sequently knew a great deal about the particular areas in question, whilo the average civilian, even in the relatively high Canadian latitudes, astonishingly littl , Any increase in the infomation and the popularity of the Arctic regions will largely depend upon ae probability to provide acceptable living tondivons on a year-round basis, As long as auch conditions do not exist, the psychological reaction of the Artic personnelexcluding Eskimosoyear or to will still be that of "camping out" for a before coing home again The Department of Northern Affair believes that the North West Territories will forever remain sparsely populated - with the exception of few areas north of Peace River, Alberta; South Youkn, West Maocenste and the stbern tip of Baffin Island. The destruetive character of the advancing Western eirilisation upon the castems and morals of the thousand-years old Eskimo culture is only too evident, Like everywhere else, it is also irreversible. The Eskim Rehabilitation Program, recently initiated in the Canadian Arctic, has the goal to educate the native and to provide him with an increasingly responsible position. Mach work an time will be required before the North 3 could be at least partially taken over by the Eskin again. It will then be on an entirely different basis as their vanishing indigenous culture, The Objectives of this Thesis are to investigate the problems connected with the design and construetion of buildings in the Arntic and to apply this knowledge in working out an overall architectural concept for a settlement in the Canadian Arntic Archipelago. The time permitting, this concept will be enlarged by the design of the laboratory and social areas as a further and final stady. The solution should provide supply storage and distribution facilities, scientific research areas, and indoor living conditions comparable to these existing at lower latitudes, It abould also attempt to integrate new materials, optia forms and procedures, which, with the exception of Thaul, Greenland9 have hitherto been absent from the Arctic landscape. CHAPTEFR Is the climate "In this storme betg the size and twentieth of July there fell so much snow with such bitter cold aire that we could starce see one another for the same ... .. whioh somewhat discouraged some of the poor. men, who had not experience of the like before, every man perarading himselfe that the winter there must needs be extreme, where they found so unseasonable a simer." ( Martin Frobishera third expedition to Baffin Island, A*). 1576 ) 5 In the regions north of the Arctic Circle there is a period in winter when the sun is continuously below the horson. The length of the dark period varies from a minimum of 36 hours near the Arctic Circle to a maximum of six mouths at the Pole. The length of the Polar Night at Resolute is 04 days. Since no olar radiation is received during the dark season, whereas the ground continues to radiate beat into space, the length of the dark period is an important aspect not only in determining the winter temperatures, but also as a psychological factor for the Arctic inhabitants. The lowest possible winter temperature which may be reached at Arctic stations has been computed theoretically by Sverdrup as .103*F. The lowest winter temperature which has ever been recorded instrunentally occurred at Verchoyansk in Eastern Siberia on February 1892 when a minimum temperature of -93.8 F was experienced. An equivalent mini=a= for the North American continent is -88 F, recorded at Aklavik, N.W.T. During the samer, the sun is above the horison continuously for a period corresponding to the winter dark season. However, the heating effect of the continuous insolation is lessened considerably by the obliquity of the sun's rays and the resultant thickness of atmosphere through which they must pass to reach the ground. The noon elevaton of the sun on June 21 is only 6 41 degrees at the Arctic Circle, 38 degrees at Resolute al 23} degrees at the North Pole, Another important factor which reduces the percentage of the solar radiation that reaches the ground in the summer is the extreme cloud cover over the Arctic Archipelago. The amount of summer cloudinoss may be Judged from the fact that in August 1948, there were only 48 hours of sunshine recorded at Resolute out of a possible 862 hours, This is undoubtedly an extrem ase but it serves well as an illustration, The finest weather is experienced in April when light winds and clear skies spread over the Arctic Islands. Land, Water and Ice. Since the Arctic Archipelago covers an area extending ever twenty degrees of latitude, one would normally expect a considerable difference in temperature to exist between the southern.most and northernmost extremities. However, a gradual decrease of temperature with increasing latitude is not appreciable in the sumer months owing to the presence of large water areas. During the brief summer period the ice filled polar waters with a surface temperature near 301' prevent the air in contact with them from warming up to any great extent. Moreover, an incursion of warm air from the South is cooled rapidly in its lower layers by contact with the cold water. As a result, the aumer tempe.ratures are uniformly cool with the average temperature of the warmest moth, July, near 400F. Most of the water surfaces are 7 frozen over in the winter. The newly-formed ice is usually less than six feet thick and there is sufficient radiation through the ice from the water below to exert a slight moderating influence. Along the shorelines adjacent to open water, moderation of winter temperatures is evident. The distance to which this moderating effect extends from the coast inland depends partly upon the topography, but in any case it is less than twenty miles. There is always some open water in Barrow Strait. During two winters at Resolute, 1947 - 1919, a bank of steam fog was often seen over the Strait even in the coldest months indicating the presence of leads of open ater. Temperatures. The severe winters and cool uimers over the Arctic Islands result in low annual mean temperatures. The hardships and suffe. ring from cold and scurvy of the earliest Arctic expeditions gave the Islands a reputation, which is not entirely deserved, of posessing an unendurable winter climate. These hardships were overcome by later expeditions with the use of better clothing, more efficient heating equipment, insulated quarters and proper diet. An important point which is not brought out by the charts of man tempratuf! 8 is the range of variability of the values of the monthly mean temperatures from year to year. A lifference of thirty or more degrees ?ahrenheit has been experienced between the February mean temperaturea during the mild winter of 1947 at Resolute and the same six years later. As the elevation of the sun increases in March, temperatures begin to rise. However, winter is still in full sway and the lowest temperatures may frequently occur during this period. Thus the absolute five.year minimm of .- 0r occurred at Resolute on March 5, 1948. On the whole, the climate at Resolute is a mdified maritime type, with extreme winter temperatures not as low and extreme summer temperatures not as high as they would be in a continental area of the same latitude. The five-year average annual high temperature at resolute has been 57 0 F. Precipitation,. With regards to the total annual precipitation, the Arctic Archipelago is one of the driest regions of the world. The annual precipitation over the islands North of the Parry group averages less than five inches a year. From December to April precipitation over this area is entirely in the form of snow. The snow crystals are sall and they are readily blown about by the wind with the result that much of the ground is bare all winter whereas deep compact drifts are formed around obstacles and in ravines. In extremely cold weather, the water vapor in the air may condense in the form of ice crystals which fall as light snow out of a clear sky. Despite the small size of these crystals, they occasionally fell at a sufficiently rapil rate at Pesolute to prodluce a thin cover of snow in few hours. June is a transitional month between the period of spring snows and sumaer rains and most of the terrain is snow free 9 luring July and August except in ravines and gullies. The maximum rainfall occurs also in Augst, with an average near bne and one.-half inches. Winds. An undisturbed air flow results in the prevailing northnws.. terly winds in Resolute area, with a mean annual of 104 mph. At many Arctic stations the megin wind speed from some directions is markedly higher than from others. In most cases the increase in speed is caused by the fact that the wind i blowing downhill so that there is a component of the force of gravity which acts in the same direction as the pressure force, Thus at Resolute, where a range of hills 600 to 800 feet high is situated to the Northeast, winds from there are about five to ten miles per hour faster on the average than wind from any other direction. Calms are most frequent in late winter, while April is generally a month with light winds and clear skies.

It is not surprising to find that a large portion of the surface layers of the northern land mass of the world is always at a temperature below freezing point. It is not generally apprewtiated, however, that about one half of the area of Canada and as much as one fifth of the land area of the world is perennially frozen near its surface. Some of this vast area consists of exposures of solid rock - as also is often the case in the Canadian Arctic Archipelago. The properties of rocky soils are not significantly changed by freezing and thawing. But when soils with organic content form the surface of the ground espe. cdally if water is present in them, their character may be strongly affected by changes of temperature above or below freezing point. The term "termafrost" should therefore be applied to all parts of geological strata, which are consistently below 32F aSd not merely to permanently frozen soils. Permafrost was recognized already by the early travellers of the North, but it is only in comparatively recent years that it has become a problem. As long as water in the samer and snow in the winter provided the necessary transportation routes and with buildings of simple design, the sumer thawing out of permafrost was relatively uniupafIbt. When, however, the frozen ground had to be cleared either for road construction or for the building of airfielda and heated buildings, the peculiar pro-. porties of permafrost made themselves very evident. In areas where the permafrost is encountered, the local annual mean soil temperature is below freeing, with the coming of the saineer the temperature of the upper crust is rained above freesing point. This thawing will be evident only in soils containing water ( fine sands and gravels ), clays, silts and some soil mixtures, and their consistency may change from solid state to wet semifluidity, The depth of the active layer may vary locally from year to year, but under natural conditions the variations will be wall. The suskeg which is so prevalent over the permafrost, especially in the lower latitudes, acts as excellent insulating medium and tends to keep the attive layer *hallow, When this or any other natural cover is removed1 the normal thermal pattern is lowered. ?rosen soil which has not previously been taved will be so affected ad the- problems of the architect and engineer begin - especially if, as is so frequently the case, the newly thawed - out soil has a high moisture content, If the warmth from a heated basement is applied to such froson ground, the problems created may extend throughout the year instead of being confined to the warm months of sumer. Many samples of soils in permarrost have an unusually high water content and a structure rarely encountered in normal soils today. This is particularly evident in the Western Aretic and brings up an interesting question about their geological origin and history, which, hoveter, belongs to a different field of sciences. Thawing out of such frozen soil following clearing for a buildirg or road construction brings about a plastic state, wher, the matter slumps and flows to places of lower elevations, once the vegetation cover is removed. In cases where the local soil is dry sand and gravel, the absence of ater fails to reveal its fromn state throurh visual inspection alone. These soil condi. tiors appear almost ideal for builLling sites, but the possible chare in ground conlitione due to removal of vegetation cover or entrance of warm surface drainage may be serious. Much could be learned about this type of influenwes from a research study on location. This study, however, will have to be a long-term project. P start has been rade at one approach by the installation of sensitive temperature measuring devices in at least two very deep holes in the Aretic One of these is the Canadian undertaking At resolute %ay, the other one at Point Barrow, Siaska. r'eOults so far obtaIned show tht the ground temperatures a're below freezing at both locations to a depth considerably in excess of one thousand feet. Permafrost layers impele the vertical drainage. ireat ex- panses of land remain wet throughout the surmer and serve as mosquitobreed!ing groundIs in the lower latitudes. The moisture content varies greatly with the physical structure of the soils, and the volume of ice may be six times that of the soil, While frozen, the ice acts like cement, bonding the individual particles so that the result is a substance of considerable 18 strength. Since te thawing characteristics topends upon the type of the soil and the original ice content, little or no complications are encountered with frosen rock or frozen dry sand and gravel. iuilding Foundations and Rlated Engineering Aspects. Just as the combination of wind and low temperatures rises certain probleps for the northern building, so the combination of the long duration of the northern winter and. its continuous darkness rises difficulties of living in the North and seriously limits the tin* luring which the construction can be carried out. because of the relative isolation, lack of locally available manpower and materials, practically all of it must be brought in from the outside at high cost. Similarly, the maintenance and replace ment of damaged or lost parts create difficulties, This one as- pect alone demands that the equipment of buildings have simplicity of design and reliabilty in operation. The technical problems that arise in designing heated buildings for the Arktic, with the exception of permafrost, differ in degree rather than in kind from those encountered elsewhere in Canada. All types of foundations can be used in the North, providing they lend themselves to the method adopted for preserving the permafrodt underneath. files have been found to be the most suitable type of foundation there, They can be used with the ventilation method and can support large structures even whsre it is tpossible to maintain the per ;afrost on its original level. -urface founiations are generally used for very small buildings. For more permanent structures1 concrete slabs or concrete pads on a gravel mat have been used. These generally require replacing the frost active soil in the active layer with a substantial thickness of coarse granular material. Among the types of structures requiring special treatment are watertanks, fuel tanks an. pumphouses. litre a layer of cloan sand is built up to a beight of three to four feet above the surrounding terrain, care being taken not to disturb the top soil except where the complete removal and replacement is necessary. The layer of sand must estend wll beyond the limits of the building ad its normal noon-day shadows, In the case of boiler houses and large scale heated buildings, the air space underneath the floor should be ample to allow free circulation of air and maintain permafrost at a stable level. The floor must be well insulated to reduce the beat transfer to the ground. Piles, either wood, steel or precast concrete, should be set at least twice the depth of te active layer in permafrost. Me length of the piling in the active layer should be surrounded with a layer of sand and gravel, the upper portion must be well greased and encircled with a thick layer of tarpaper to prevent the frost and adhesive forces from lifting the pile, Por the same reason, the lower portion should be left rough or notched, The Water Supplys Aithough there are numerous ponds and lakes existing through- out the Arctie, these are relatively shallow, During the winter period most of such bodies of water are froen to the bottom. The water sources here must be deeper than ten to twelve feet before they can be expected to provide some water throughout the year. Although the ice cover rarely exceeds eight feet, only little liquid water remains below. In addition to this, mineral and organic contents of the lakes are concentrated in the unfrosen parts, often rendering the water undesireable or unsuitable for domestic use. Most of the lakes are products of retarded drainage through the peruarost layer and only few have under. ground springs as a continuous source of supply. Thor are comperatively few rivers in the Arctic, large enough to maintain an appreciable flow throughout the year, but none of them exists in the Arctic Archipelago, with the exception of, perhaps, Baffin Island, Where the larger rivers do exist, their utilisation in the permafrost region is further complicated by the bottom ice ad ice sash ( frasil) clogging the intake structures at midstream. Suggestions have been made that deep wells tapping the subpermafrost water offer excellent possibilities for a year-round water supply. A particular advarAg to well water is its low turbidity, eliminating the need for large settling basins. Against thia stands the difficulty of locating the sub-permafrost water and well drilling through a frosen layer of several hundred or even over thousa nd feet - as is the case at Resolute, Due to their scope and complexity, all these problems lie somewhat out- side the limite of this thesis research. Sewage Disposal. tow temperatures are also the greatest drawback in the effivient operation of sewage disposal systems. Biological and chemical reduction of organic matter is very slow. Where the customary practices of disposal are used, permafrost prevents proper filtration and leaching into the soil, resulting in a poor drainage and vaste accumulations on the surface, Unlined pit privies and septic tanks are now in comon use, but have proven a poor practice. Even the primitive pail system is often used for disposal of human vastes. Because of the limitations mentioned before and also due to the lack of sufficient water systems, very few water - arried sewage collection syst ma have been installed in permafrost areas, To keep the sewage lines from freezing, they are usually enclosed in a heated conduit or utilidor. Savings can be achieved if the pipes can be placed directly into the ground, rather than in an enclosure above it. The feasibility of such installations depends greatly upon the behavior of soils and permafrost in the given area. Rock outcrops, frost active soil and high ice contents are the liniting factors. Due to the warm waters, severs are less vulnerable to freesing than water mains. Sewer lines should be veil insulated even below the ground and their placement under roads or other compacted soils should be avoided. One method of sewage treatment receiving increased con- 22 aLderation is sewage lagooning. Providing for biological or secondary treatments, this system discharges raw sewage into large shallow oxidation ponds. Pperience has indicated, that properly constructed ponds work satisfactorily in cold climates. The main advartages here are the low initial and maintenance costs and trouble free operation* Superstructuresa Special Considerations for the North. One of the advantages of the standard wood frame construeo tion hitherto used in the Arctic is its ability to deform aut ficiently without damage, thus taking up some of the movement that may be produced by the action of permatrost on shallow foundations. The same point has been a definite disadvantage to prefabricated rigid panel structures: reduced weathertightness at the joints has resulted because of the foundation movements. panels made out of synthetic materials, with properly detailed weathertight connections and greater elaeticity are holding a definite promise to the improvement of weatherproofing in the Northern construction of the future. Thermal insulation materials in bulk form are preferable to the multiple air layer systems or reflective insulators. The obvious advantage of the latter is their lightness and compactness in transportation. However, reflective materials used alone, have given poor performance in very cold areas due to convective actions in air spaces. The same, although in a less pronounced way, can be said about the insulating materials relying on I" to 2" deep flat air spaces as their only elements to resist the heat flow. Condensation of water on the interior surfaces of the outside walls and within the walls themselves to perhaps the greatest single source of difficulty with the buildings in the Arctic. Rotting of wooden structures, water stains on the ralls and ceilings, wet insulation and the consequent compaction and dim-. placement of the rockwool pads used, peeling of paint on the exterior wood surfaces have shown the disadvantages of the cue. tomary design and construction procedures. Because of the lower surface temperatures, condensation occurs first on the windows, This can be controlled by using triple glazing. Other areas of high heat flow, such as metal clipa, exposed nail heads and recessed switch boxes have to be eliminated or covered with the maximum of insulating materials. The installing of an unbroken plastic film or impregnated paper on the inner side of the wall has been effective insofar it has maintained continuity of vapor control across the panel or construction joints. Thermal conditions in the wood panels or stud construction hitherto used are also made difficult by the incorporation of mechanical or electrical conduits and other parts, particularly of interrupted vapor barriers. This has resulted in the surface mounting of the same and consequent unsightly arrangements visually. The result of airtight construction is an increase of relative humidity within the buildings, which in turn introluces condensation. Forced air ventilation or small louvered outlets may have to be introduced to solve this problem. Resistance to Fire. Becouse of the isolation of Arctic settlements, the length of the cold season and the extremely dry climate, the danger of fire in the North is of far more serious consequences than anywhere else. By the use of wooden construction it is difficult to erect structures of more than one hour fire rating. Exterior and interior finishes may have an important part in remedying the situation, but the solution of the problem lies in the selection of other materials ad methods. While the cold climate and related beating questions denad compact design features in any building for the Arctic# the location of the buildings and their wide spacing because of the necessary fire separations has hitherto worked in the opposite direction. The paint alone has been unable to render the conventional wooden structures safe. Heating. The greatest possible temperature differenoes occur luring the polar nights when a gradient of 120*F to 1300? may be ex. perienced. Fortunately, during the extreme cold spells the weather is nearly always calm, The units of any dwolling complex should be not only well insulated but also with small perimeter dimensions :id outside surface areas. Theoretically, np'erical shapes are the most advanta eous. They are but of limited use only where ine.rnal importanec. nace subdivision is of any To keep the foundtions in their frozen state, open space is left on the underside of buildings. Adequate heating at the floor level is difficult in such conditions because of a high heat loss through the floor. Even ith substantial amounts of insulation the heat must be introduced on or at the floor level to naintain acceptable temperatures and to combat the convective air entrents. Without proper heat distribution, temperature differences of 5 0 F have been experienced between floor and ceiling. This ca~n be soved by either forced air circulation or a double floor design, to be used as a plenum through which the warm air is drawn before entering the room. The latter method does not require fA systems thus saving electricity which in turn can be used for more advantageous purposes. areas are generally small, rinlow and the psychological impression is rather depressingo To reluce the beat loss of large inhows, triple gazing is used, At night, a drapery woven of wilium reflective material could also be drcsn around the inside of windows or dome lights. 1; C.A. Mills, "A Year's Operating Results for Reflective Radiant Conditioning." 26 New Alaterials aw Methods. The value of factory-produced components is universally recognited as a means of rapid and economic building, particularly where vaste and the amount of field work has to be reduced to a minimum. The high cos of transportation is the result of the absence of shipping piers land mechanized unloading facilities at the preient Northern supply baaes, but it also suggests econoiies in using light weight materials. This has led to increased interest in building sybtemsa in which 4weight reductions can be achieved, particularly those using plastics. Foamed polystyrenes and plastic impreginated paper honeycombs have recently been used as lightweight core materials in sandwich panels. The skins of such structural panels may be of a variety of materials. The foamed polystyrenes with their high strength - weight ratio, resilience, excellent thermal properties and high resistance to water vapor transmission and absorption have already proven to be particularly suitable for this type of use. Because of higher strongth than poiystyrenes, but also more expeasive, polyurethane is also a promising material for sandwich panels. Improvements in manufacturing techniques have made the prefabrication of plastic panels with lightweight plastic cores competitive with wood frame panel systems, hitherto extensively used in the Canadian Arctic. In contrast with the plastic foam corea, fiberglasarcinforced polyester sandwich panels or shells have not entered the northern construction field at all. laining its strength in a manner similar to reinforced concrete with steel rods, the physical properties of this compound product are superior to stal in several respects: the strength-weight ratio to higher, it is immune to corrosion and its resistance to abrasion is another asset in loading processes. To obtain the highest strength characteristics, the fiberglas reinforceAg can be obtained in fabric weaves. Another advantage of its use in the Aretic is the improvement of the structural properties by a decrease in tem. perature. By choice of the proper resin, it is possible to determine the degree of flexibility of the resulting product. It is also possible to obtain transparent sheets - such as t Duralux", transmitting 90% or more of the visible light. The allowable tensile strength for fiberglas cloth No. 14P, a unidirectional weave laid in cross laminate is 47800 pai, and panels or roof shells would have to be manufactured with several layers of translucent or opaque insulation between them, When considered in their relation to their potential savings in transportation charges resulting from tecreased weight volume and the reduction of on the site construction time, all-plastic panels do offer a means of reducing overall building costs in the North. They may aiso provide an answer to great many other Aretic construction problems and a better future environment within and without. 28 The appearance of liquid plastics in architecture has been scareely investigated. Casting, impregnating concrete with a liquid, setting resin which would mechanically fill the tiny pores and transfer concrete into a positively impervious material has been thought of, but very little use has been made of the forming technique by blowing. Characteristically inherent to meny plastic materials, this procedure has been limited to the manufacture of small objects from a viscous liquid or from heated and softened material. The excessive labor costs required for forming the wooden negative is the hindwance to the progress of reinforced concrete shells. To blow a large shell out of a plastics material would simply require placing of the viscous resin in a saucer - like shell built on the ground or atop a base structure and blowing a current of compressed air from underneath. The viscosity of the resin and the pressure required has to be worked out, but once achieved, this procedure could be adopted for great many types of structures, rendering the formwork obsolete* The resulting structure would be a smooth sphere or a modification of it and even the forming bowl could often stay in place and serve as a foundation. Reinforced Concrete. What is the durability of plastics in a long time span under northern conditions, we do not know. Concrete will possibly endure for centuries, while steel gives every indication it will 29 not. The latter is also unsuited for Arctic requirements. Plastics are materials of definite serviceable properties. They can be used and they can be protected, but for certain structural functions, particularly loadbearing below grade, no replacement for concrete can be foreseen in the nearest future, Auger - sunk concrete piles, concrete mat foundations on gravel pads and below grade parts of retaining valls have serviced well in supporting imposed loads on permafrost. Duildings at Thule Air Force base in Greenland were first prefabricated from aluminam -clad plywood, then, in successive years from metals and finally from concrete, as the experiments in the field led to improvements of design. It would be also inapropriate not to mention the extensive use of concrete in the T*.E.. line and the corresponding Mid-Canada line. The fact that they were carried out without regard to normal economic considerations does not make all the construction experience gained directly applicable to civilian building in the North, but the completion of the o... line on schedule will be a continuing challenge what can be done in the Arctic when the necessity calls. Concrete is heavy in its pure form, but the abundance, of gravel, sand and water at many Arctic building sites justifies its use even for cast in place procedures. A satisfactory result is dependant on irmple, light and reusable formork. There the same set of forms can be used reneatedly for many buildings over a "ide Northern district, plastic £orms seem to hold a great promise. 'a fibre reinforced MLk C HAP T E R IlI the site The -ite for the thesis desig study has been chosen at r$esolute Pay, on the southern tip of Cornwallis Island. The motivations for the particular location were as follows: "esolute in a comperatively swall but ireportant Arctie outpost, whick till renain relative ly stable in its size and the number of inhabitatnts because of its Far North location and the charactor of its fuwction. It is a point 4ohere the main wreather data of the Aretic Archi pelago are collected and4 broa-cast, the :teriniral of the Arctic supply convoys and the wain iistribntion centre for the northern half of the trchipelagvo an rel as the ireite lands routh. The shiping season at Resolute is two to three 'uonths a year and this baze is the inst point accessible by regular ships and ocean tankers accompanied by an icebreaker. Terrain and Soil. Rtesolute is located 74041*03" N, 945417" W at an elevvtion of 56 feet above sea lotel. The terrain of Corwallis isand is characterired by a plateau remnant in the southettstern cuarter of the island, where it borders about twenty miles of the 2onth and East coasts that face Harrow !trait and Wellington Channel respectively. The surface of the plateau is undulating and truncated nountains are a characteristic feature. It is crossed by several streams, steep in gradient and characterised by canyons with numerOus waterfalls, while large intervening areas are devoid of riAinage lines. A range of hills up to 800 feet high rise innetiately to the North and North East of Resolute Day. There is another, seperately standing hill of approximately same elevation Southeast of the site, Many parts of the coastal regions of Cornwaltis Island are low lying plains, especially in the reat and Northwest, that slope gently seaward and on which major streams flow through generally evengradb1 channels, often several miles in length, before reaching the sea. By far the greater part of the surface of the island is covered with Clay admixed with frost-shattered debris from bedrock or of frost shattered rock alone. Limestone and dolomite formations with shale, sandstonesand coal deposits Northwest of the stony Resolute Flats should be noted. The settlement area is a well-graded slope of frost shattered limestone and small clay admixture, falling gently towards the Barrow Strait and Wellington Channel, The depth of permafrost is well in ex.. cess of one thousand feet with an active layer of twelve inches. Plants, represented mainly by grasses, lichens and mosses, grow mostly in broad valley floors and on the coastal slopes about Resolute and other points. Uplands in excess of 300 feet have little or no plant cover, There are several small fresh water lAkos immediately adjacent to the site, most of which freeze to the bottom during the more severe winters. The sea, particularly in the center of the Straits, has open leads even in the severest of winters. A Sumary of the Dry Analysis. Because of the peculiar climatic conditions, the shortness of the building season and long and expensive supply routes, a satisfactory solution requires the mobilisation of all technical reIsolation. sources of the day. Remoteness and transportation problems are still the most serious considerations of all northern building. When thought is given to the volume and weight of materials involved in the construction, it can be readily seen that marine transport, though sometimes complicated by the sea ice conditions, is the only sensible approach to building material shipments. To make a full advan. tage of the short summer, planning and freight deliveries shoult be made at least a year in adVance, enerally high cost of imported fuel justifies Cold The Climate. heavy insulation. Effectite vapor barriers are a collateral requirement. In selecting thermal materials, bulk type fire resistant insulations such as synthetic foams or mineral wools are preferred to multiple air layer systems. The need for conservation of heat 'uggeSts introvert structures with heating, water and sever lines combined and buildings of minim= exterior surface areas. Snow Because of the dryness of Resolute area luring the Drifting. winter months, the formation of very dense snow drifts around the obstacles is of lesser importance than in the Western Arctic, Flat roof structures to not accumlate snow on rooftops, while all pitched roofs do. Proper orientation and shape of buildings is here also important. Practically all of the builling materials have to be transported from lower latitudes. As much as possible has to be prefabricated and easily Properties stowable - either compact or light in weight. Other of properties required are high insulation values, Materials. high resistance to low-temperature weathering, fire resistance, simplicity of asnembly and low maintenance factor. Permatrost. For large structures at Resolute, concrete pile foundations on bedrock could be used, with the gravel paA - concrete mat system for buildings of less founlation load. Water would be supplied either by a deep well or from one of the freshwater lakes. The dredging of a deep and insulated filtration reservoir would be necessary in the latter case. Chemical toilets or frost-protected sewer lines with moss insulated oxidation ponds seem to be the two alternatives for sewage lisposal in permafrost. Cf A P T E IV Geopsychology of the North. Climatic and weather conditions, together with fort, color, existing light and movement in any landscape are important in-. fluential factors of human psychology. The m total of such influences seems to remain constants in locations, vhere some of the natural phenomena have a diminishing intensity or are absent, more importance is grained by others. The problem od acclimatization is closely related to the natural characteristics of the Arntic and Subarctic regions. It is also a rather peculiar one. The polar winter night leaves a very powerful impression upon everybody who has lived through it. Even the natives or people with long northern experiences cannot be looked upon as fully acelimatizedl to the cold nights of several months duration. Melancholy, the lowering of mental productivity and other psychological symptoms are experienced subjectively as well as observed by others. Perceptible chan- ges are evident ifter every winter. Their intensity depends on the combined environmental influences and may occasionally give a person the feeling of sickend*g waknens. Thile the subarctic sumner with its sun, high temperatures and liit winds more than compensates for the polar darkness, the tretic proper with similar geophysical occurences of much longer duration, carries new problems with it. Here the polar night tnd polar day give experiences of much greater psychological intensity and the 35 expected degree of acclimatization is less both physically and psychologically, Because of the white Arctic samwer nights, sleep in difficult and often neglected. The absence of daily changes of light and darkness lessens its depth under all conditions. Polar Nervousness. In the stricter sense of the word1 Amost all people living in the proximity of the Arctic ticle are influenced by the climate and only partially acclimatized. For many a newcomer it is even more difficult to adjust himself to the existing conditions. The reaction appears after the first arctic night and lies deep. Not everything can be corrected by the following sner day. Compulsion is to brood, mental sidetracking, whimsies, weakening og memory, loss of self-reliance may all be created during the dark season. with the advent of continually lit arctic spring, te long periods of brilliant sunshine carries with it an almost unpleasant and jarring impression. Exitement is experienced without the disappearmnce of winter nervousness and a rurious mixture of indefineare feelings is unavoidable. A yearly graph depicting the physical and neAtal capacities of an individual in the North cin be drawn. The line here would show a general detachment of the above capacities during the long winter montha, whereby the mental activity is on a downgrade, while the physical one rises. The spring and early sumar brings both together again, while another low occurs during the latter part of the smer and early fall, The oscillations described here are based upon medical, psychiatric and educational observations and are in general lines characteristic to the majority of arctic personnel. The modern has a tendency to identify himself more with his microclimate both physically and psychologically, replacing the powerful natural forces to a secondary plane, and rendering himself far less susceptible to te Polar nervousness. An intereeting byline on the topic periolicity can be seen in the hybernation of animals. Wile a number of nations call this phenomenon the "winter sleep", the affected creature may get into the lethargical condition at various times of the year be it in the summer, spring or 'Anter. Uowever, there are many reasons to believe that hybernation has been as&cciated only with the cold period of the year and has been displaced or oppressed by the migrution and associated climatic changes in the following willeniums. The feeling of tiredness, the loss of interests and depression are unusual feelings for people during the subpolar and polar winter, but may be quite natural reactions of atavistic nature. In the parts of the North, where rzoified maritime climate with overcast susmrers prevails, the efIfects of polar night have a cumulative nature. The spring sun and clear April flies cannot be, the equivalent to the long sunny day elswlore in the Continental Arctie: the short and overcast sumer sets in too soon. Here the importance of controlled microclimate to the psychology of arctic personnel becomes much more evident: low hanging clouds and foggy landscape is a poor improvement over the crisp and clear atmosphere of the polar night, Ath the passing of time, northern service personnel show an increased desire for privacy. An intense wish to be alone, to read or study is more pronounced in small isolated conunities of loss than 20 to 30 men, where the same faces are seen for monets on end. in a group ten times larger the quest for privacy should be less important reason for creating mutual tensions, particularly under the balancing influence of residing wives and farailies, C H AP TER V A major consideration with reference to the future levee lopment of the rctic will be based On its supply of raw materials. One of the immeliate taka is to find ways and means of supplying fuels for local consumption. Until nuclear reactors are available on a comaercial basis, the finlinga of geoilogy section will have to serve this purpose. All research personnel would be operating from Resolute as the main center, while sub--bases are changed constantly to enable a thorough coverage and familiarity of field conditions4 Lutomatie weather stations are accepted in meteorology, but their information is not always sufficient and reliable, Pesides the two branches mentioned, the research of the atmospheric strata with balloons and rockets can only be carried out by professional personnel. The distribution of life forms in the atmosphere, on land and at sea has to be aaother phase ia the overall Arctic research pattern. Biology, oeanography and timnotogy are closely con-. nected in this investiration of the natural environment and means by which life exists wider prevailinr con Iitions. Much of it has alrealy beaaccouplished but even more has to be done. The territory is very large in every sense of the word and hitherto understaffed in scientific and service personnel. 39 The People. At the present, the civilian population of Cornwallis Island is about 15u people, 80 of whom are Eskimos 9 the remainder is the personnel at Resolute settlement. The station there Is being enIarged on a bunkhouse-after-bunkhouse basis. A part of the go. veramental Northern Administration apparatus will be established here and substantial expanaion of te scientific activities are planned. The future number of people at Resolute is estimated at 250 to 275. The settlement would be operated by a Crown Corpora. tion and the character of the stay in the proposed colony would still be on & temporary basis.. with the exception of the rehebilitated Eskimos, The .C.A.F. establishment and its function at Resolute has been purposedly ezluded. The following is a tentative suggestion of the administrative, professional and maintenance personnel required for the various objectives mentioned beforehand and determined mostly from the interviews with Canadian Government officials in the Department of Transport and Department of Northern Affairs.

The wives and children of the personnel ,ill be stayting in the North for the duration of ti, but the numerical increments of family setup will be somewhat different than in an usual community of lower latittdes. 41 More than one half of the present personnel at Resolute are bachelors, This factor, although strongly uodified, may be carried over to the future developments of the Northern Arctic. A couple without ebildren will in many instances be both in the numbers of the active personnel, and with the pos. sible exception of the Eskimos, there will be very few - if any - large families of five or more persons. Imposed limitations in the schooling of children and other factors, such as high cost of living, will force this ecological groug to tay out- side the Northern Anetic. The average family with children is calculated to be 3.3 people, and the population setup is tentatitely inticated belows Population Grouping by Family Working Women a Northern AdmindBranch 3 Status and Numbers Supplies Office 2 Single Men Maintenance office I Orderlies - Cleaners 2 Married Couples .!itchen Personnel 5 no Children Technical Serv.

This could be arranged by daytime activities for all childrem and evening classes for aults. Besides emall recreational areas for each of the families, larger facilities for common recreational purposes are very importqnt. Because of the low temperatures, wind and darkness, the people will stay indoors for the ;roatest part of the year. The erettion of enclosed passages between buildings is a common and proven arctic practice. These corridors eliminate the unpleasant experiences of a possible 1200F to 130 difference in temperature and become vitally important under polar blisard conditions. While the climate is rfther vigorous, the Polar air is remarkably germ free. Colds and flu are experienced very seldom and accidents or disorders of biological nature cause the greatest number of medical mercy flights. Most of the serious cases are flown out and only local infirmaries of small scale are used for the personnel tending the Arctic stations. To provide amenable living conditions for the 275t, facilities have to be included which would normally represent a settlement of much larger size. Although few of the areas nay double in their purposes, providing church services in a library area or movie shows in a dining room, certain minimm possibilities of combined functions exist. Projecting a concept in broad outlinea, the organization of the settlement would include a section housing the adminiatrational and non-scientifie functions, with living quarters somewhat detached, Their subdivision in several apartment like groupangs vould eliminate a forced feeling of couaunal quarters. Such a layout would also reduce expensive hetting and utilities, normally associated with decentralized single family dwellings in cold climates, Since only a limited nm.ber of supplies and food requires protection from the cold, a large part of the storage area would be left unheated, All laboratories could be interrelated but not necessarily in the immediate proximity of the other areas. 44 Area RtquirEments. Based on the functior.z of the Resolute settlement outlined before and on the data supplieg by the Governmental Offices in Ottawa, the biggest enclosed space by far is require for the storage of supplies. In awer 1958, the amount of cargo for Resolute and all other outposts in the Eastern Arctic totalled 53 tons per man per year, including construction materials, supplies and machinery. With the base construction finished, a warehouse ~ storage space of 1.5 to 175 million cubic feet should be considered ample to meet the current requiretments of the area, Ther would be apperate storage aroas for the scientifio mate. rials and for the goods of the Hudson's fay Company. Living space indicated below includes sleeping and lining for all residents and recreational areas for the families only. Other areas for indoor sports and more specialized recreational facilities should be added, The figures here representttrea totals of above minimum averages required for one to five per.son groups living under normal conditions, Since the objective of this study it the development of an overall architectural concept, the working out of minor details would not contribute appreciably to this stage of work. 45 Administration: Techn.Mgr.and Assistant 400 Connmunication Services: Radio 450 Scient.Operations Mgr. 400 TV 900 Northern Administration 900 Office 200 1550 (R.C.M.P. included": Supply Officerts Office 350 T iving 2 Gen.Offices 9 300t400 700 Library and Chapel 3500 H.

The architectural solution for the Resolute settlement has to be a clear statement speaking by itself rather than blending in the surrounding landscape. The use of color and an overall impression of mass and fom have a definite psycho-. logical influene against the barren landsaepe of the North. More than in the temperate monea, the settlements of the Aretie take on a character of very definite landmarks rather than remain anonymous concentrations of poaple. It would be incorret to ignore this aspect and to provide a different answer to the rocky island's climatic rigors by building mostly underground. The seiquence of interior spaccs and a feeling of protection would have the greatest importance for the inhabitants of the future rzosoluto at all times. The architectural content of the development should therefore express both the climatie conditions as well as the functions and aspirations for which it has been intended * -AMMOMMOMMAI.- Bibliography.
