Kujala Data Report No. 8 Office of Naval Research Contract Nonr 1286(02) Project NR 083-102 Edited by Elizabeth Strong Reference 62-11 September 1962 Wayne V. Burt Chairman INTRODUCTION During 1961, a program of shore station sampling of ocean temperatures and salinities was carried out by the. Oceanography Department of Oregon State University. This is a continuation of the work reported by Kujala and Wyatt (1961). Sampling was conducted at 11 locations along the Oregon coast and at one location in northern California. Temperature and salinity samples were taken by interested persons living along the coast. Without the participation of these individuals this program could not be successfully carried out. Table I lists the sampling stations by name, the location where the collection was made, and the observers. Figure 1 shows the location of each station. METHODS AND PROCEDURES Wherever possible, sampling sites were selected at points where the influence of fresh water runoff was a minimum. Observations were made as close as possible to the time of high tide. Temperatures were read to 0.1°C using a calibrated thermometer contained in a brass bucket with a plastic liner. Water for salinity analysis was stored in pressurestoppered citrate bottles; titration was completed three to four months after the samples were collected. The method used was that described by Strickland and Parsons (1960) (estimated accuracy ± 0.04%). Salinities at Seaside Aquarium and Crescent City were computed from salinity hydrometer reading, using tables from Zerbe and Taylor (1953). RESULTS Table II lists each temperature and salinity observation taken during 1961. Table III presents summaries of these data in the form of monthly means, maxima, minima, range, and number of observations. Monthly mean values of temperature and salinity at four stations are plotted in Figure 2. Seasonal temperature ranges along the coast for the latitude were small, , particularly off central and southern Oregon (Otter Rock and Humbug Mountain). This is attributed, at least in part, to summer upwelling. Salinity ranges were large and the variations show dependence both on runoff and on upwelling. To the north , (Seaside Aquarium and Arch Cape), salinity minima occurred from April to June, showing the effects of local precipitation and of the Columbia river runoff, which was a maximum in June. In central and southern Oregon, the local runoff led to the development of a sharp surface salinity minimum in February. Upwelling in the southern region maintained the salinity at high levels from June to November. The means for the Columbia River Lightship are plotted in Figure 3. The striking feature here is the exceptionally large salinity range, from an ocean-like high of 32%, in January to only 17%. in June, when the Columbia outflow was a maximum.
