INTRODUCTION This report presents observations from moorings of temperature, conductivity and pressure, made during the Arctic Internal Wave Experiment (AIWEX) in March-April 1985. • The main objectives of AIWEX were: To make comprehensive measurements of internal waves and microstructure in the Arctic Ocean, and • To identify important processes that affect the Arctic internal wave field. To meet these objectives, observations at a variety of horizontal, vertical and temporal scales made by investigators from many institutions will need to be analyzed. The purpose of the temperature and conductivity measurements was to provide time series from which inferences could be made about the vertical displacement of the internal waves. Specific goals of this project include: • To verify the suspected low spectral level of the internal wave field in the Arctic Ocean, • To estimate in detail the coherence structure of the highfrequency internal wave field from horizontal and vertical arrays of sensors, and • To compare variations of the internal wave field with variations in the surface stress, eddy field and dissipation. 2 INSTRUMENTATION A total of 13 temperature (SBE-3), 5 conductivity (SBE-4) and 2 pressure (Digiquartz) sensors were deployed on 7 moorings (Figs. 1 and 2). The locations and technical details of the sensors are given in Table 1. Each mooring consisted of an individual 3-conductor, shielded electrical cable (Belden #8771) for each sensor attached to a strength member of 1/4" Samson Dura-Plex Braid (Composite Polyester/Polyolefin). The moorings were secured at the surface of the ice and kept taut by a steel weight at the bottom. A schematic of the data acquisition system is shown in Fig. 3. The output of each sensor is a frequency that was fed into a 20-channel SBE 11/20 (Sea-Bird Electronics) Deck Unit. The Deck Unit digitized the frequency signal using a highly accurate hybrid period counting technique. A PDP 11/23 computer acquired the data through an RS-232 line and averaged values over 1 minute intervals. The data were then written on 8" flexible disks and displayed on a terminal and printer. For limited periods data were also recorded at a 1 s sampling rate. There was significant data loss during the first week of operation, apparently due to a bad electrical contact on a board in the SBE 11/20 Deck Unit. After cleaning the contacts, the problem did not reoccur. Small gaps in data throughout the experiment were due to power interruptions (both scheduled and unexpected). Noise spiking was present on some channels due to a timing error in the Deck Unit; we believe this did not significantly degrade the observations in the internal wave frequency band. Calibration All the temperature and conductivity sensors were calibrated in November 1984 at the Northwest Regional Calibration Center (NRCC). The conductivity calibrations are referenced to the Practical Salinity Scale (1978) which defines the conductivity at 35 ppt, 15°C, 0 pressure to be 4.2914 Siemens/meter.

Cent ra a' Sate! ii te Mooring Fig. 3. Schematic of data acquisition system located in a hut over the central mooring. 7 sensors were used as supplied by the manufacturer (Paroscientific, Inc.). Pressures were converted to depth assuming a constant water density of 1028.13 kg/rn3 in order to be consistent with the measurements made with the Arctic Profiling System (APS) by James Morison (University of Washington, Seattle). After AIWEX the behavior of the temperature and conductivity sensors were compared by placing all the sensors in the OSU calibration tank. While this comparison was not directly traceable to an absolute standard, the sensors could be compared with two SBE-3 sensors (#544 and #607) that are used routinely in the OSU calibration lab as secondary standards. The differences between the pre-AIWEX calibrations and post-AIWEX intercomparison are given in Table 1 for each sensor. The difference in sensitivity between pre- and post-AIWEX calibrations was small for all sensors -- less than 2%. Sensitivity is defined to be the change in temperature or conductivity per change in sensor frequency; the values in Table 1 were estimated by measuring the change in the sensor frequency over the range in temperature from -0.0392 to 0.0396°C or over the range in conductivity from 2.7360 to 2.8766 S/rn. The difference in the absolute calibration varied with the sensor but was no larger than 0.015°C or 0.0011 S/rn. For each sensor the difference between the NRCC calibrations and the post-AIWEX intercomparison were calculated. The mean and standard deviation of these calibration differ- ences based on 6 calibration points are given in Table 1. The new temper- ature sensors with serial numbers 6xx were very consistent with each other and measured 0.009 to 0.013°C higher in post-calibration. The earlier model temperature sensors with serial numbers 4xx differed by -0.005 to +0.004°C; sensor #424 failed upon recovery and could not be recalibrated. The apparent systematic calibration differences between old and new sensors has not yet been explained. 8 Even though temperature sensor #615 moored at 508 m performed consistently in both pre- and post-AIWEX calibration, a very significant offset in calibration was observed when the sensor was in situ. reproduce this behavior in the laboratory have failed. All attempts to It does appear, however, that the relative temperature fluctuations measured by the sensor are reasonable. Comparisons with the temperature at 508 m measured by the APS throughout AIWEX indicate that the temperature offset was +0.11°C. Therefore, this constant offset has been removed in all the data from #615. and Recovery The moorings were deployed in and around the AIWEX ice camp located about 350 km north of Prudhoe Bay, Alaska. The position of the camp as a function of time determined from satellite navigation is shown in Fig. 4. Deployment of the central mooring began on 19 March CMT from inside a hut. A 200 lb. weight was first lowered through a 16-inch diameter hole in the 2.5 in thick ice. The wire and sensors were then attached to the strength member with plastic cable ties. The satellite moorings were installed through an 8 inch diameter hole by first unspooling on the ice the entire length of the preassembled strength member, wire, and sensors. The top end of the mooring was attached to a snowmobile, and a 100 lb. weight and the rest of the mooring was lowered by driving the snowmobile toward the hole. An oil drum lying on its side near the hole provided a smooth surface over which the mooring could slide. Recovery of the satellite moorings began on 26 April; the central mooring was recovered on 29 April. Since the satellite moorings were left to freeze into the ice, recovery was made through a new hole that was drilled within a few feet of the mooring line. A hook on the end of an L-shaped pole was used to snag the line, and the mooring was pulled up with the aid of the snowmobile. The hole for the central mooring was kept free of ice by adding heat from the oil-burning hut heater with a heat exchanger. A small electric winch was used to retrieve this mooring.

Unfortunately the response times of the sen- sors are not the same; the temperature sensor has a 200 ms time constant while the response of the conductivity sensor is controlled by the flushing rate of the water through a tube 0.2 m long and ranging from 4 to 7 mm in diameter. A simple model was developed to try to predict the tempera- ture inside the conductivity cell, T1(t), that could then be used with the conductivity measurement to calculate salinity. Assume in time At the heat that leaves the cell is given by C b Iw(t)I T1(t) At where C is the heat capacity/volume, b is the cross-sectional area of the cell, and Iw(t)I is the speed of the water flushing through the cell. During this same time the heat entering the cell is C b tw(t)I T0(t) At where T0 is the temperature outside the cell measured by a nearby temperature probe. Hence the change of total heat inside the cell is equal to the heat entering minus the heat leaving: [T1(t-4-At) - T1(t)] =b Iw(t)I [T(t)-T1(t)] At where 2 is the length of the cell. well-mixed and w(t) Assuming that the water in the cell is constant, dT1(t) + dt 1 — T1(t) = 1 — T(t) (1) r r where r = bw/2 is a flushing time. The frequency response of T1 to a fluctuating outside temperature of the form T = exp [iwt] can be expres- sed by T(t)2 I T(t) with T1 lagging T by a phase = 1 (l+w2r2) (2) 11 9 = Atan wr (3) Equation (1) is easily applied to T(t) (measured) using finite-difference methods to calculate the temperature inside the cell, T1(t), once r is determined. To determine r, the T and C measurements from 257 m are used. It is anticipated from historical data that salinity is linearly related to temperature over a small range around 257 m, and can be expressed by S=A1T+A+e (4) where e is the error in S due to violation of this assumption. The empirical equation relating T and C to S is nearly linear over the small range of T and C that is observed from the sensor at 257 m and can be written S=aT+fiC where a -1.11 ppt/°C and (5) 13.51 ppt/(S m1). Therefore a linear relationship between T and C can be written from (4) and (5): (A-a) C= A T+ (6) fi We therefore assume that C(t) is linearly related to the temperature measured inside the cell, T1(t), and that the observed phase between C(t) and T(t) is representative of the phase between T1(t) and T0(t) (Fig. 5). In order to interpret the phase in the context of (3) the coherence must be 1, that is must be small. At high frequency the coherence is lower indicating that e may be significant, and the interpretation of the phase is more complicated. At low frequency the phase can be reasonably reproduced by (3) with r = 4 minutes (Fig. 5).

As expected, the 4 minutes reduces the phase difference at low frequency. The phase difference at high frequency may be due to a breakdown in the linear T-S assumption (4) and/or in the simple filtering model (1). We believe the latter effect is dominant, primarily due to the variability of r. Therefore, calculated salinity is less reliable at higher frequency. At the depths of the other four pairs of T-C sensors, a constant, linear T-S relationship clearly does not exist, and this method cannot be used to estimate r. Hence the same value of r = 4 minutes was used to estimate T1 at all depths. There is some interest in knowing how well S can be inferred from T. One method of determining this relationship is by linear regression analysis. The data were first averaged over 15 minutes to minimize any error in estimating r. The best-fit values of A from (4), the percent and of the S variance that can be explained from T, and the correlation coefficient between T and S are given below for each pair of T-C sensors: Depth % S variance explained Correlation coefficient A1±90% conf.lim.
