5 ABSTRACT The Coordinated Eastern Arctic Experiment (CEAREX) was a multi-platform geophysical study covering the period from winter 1988 to spring 1989 in the vicinity of the Yermak Plateau and Fram Strait. The Oceanography ("") Camp component of CEAREX was designed to study the physical oceanographic conditions from the deep Nansen Basin north of the Yermak Plateau, then into the shallower water over the Plateau. This area was known from previous experiments (Fram III, Fram IV, MIZEX '83) to be a very energetic region, in which much of the decay of the Atlantic Water flowing into the Arctic Basin occurs. The various programs at "" Camp obtained data which will improve our understanding of the decay mechanisms, including the role of topographically enhanced diurnal tides, internal waves, and mixing by ice stress at the surface. Our component of this project was the direct measurement of microscale velocity shear, temperature and salinity, using the Rapid Sampling Vertical Profiler.

8 INTRODUCTION During CEAREX (the Coordinated Eastern Arctic Experiment), more than 15 profiles of temperature, conductivity, and velocity shear microstructure were obtained from the Oceanography ("") Camp in March and April, 1989, including a 2-day continuous time series from 5 April to 25 April. The camp was established on the drifting pack ice north of the Yermak Plateau, and was carried from deep water (> 4 m) onto the northern slope, then around the plateau in about 17 in of water for several days before heading westward across northern Fram Strait (see Section 1). A: The Experiment CEAREX was a multi-investigator Arctic oceanographic experiment conducted from several platforms, including the "" Camp from which the data discussed herein were obtained. Other data from "" Camp include Acoustic Doppler Current Profiler (ADCP) measurements in the upper several hundred meters, and densely sampled CTD data, as well as water depth and meteorological information. Table 1 lists the other Principal Investigators at "" Camp. Approximately 15 microstructure profiles were made with the Rapid-Sampling Vertical Profiler (RSVP) [Caldwell, et al., 1985; Padman and Dillon, 1987] from March 31 to April 25, 1989, between the surface and a typical maximum profiled depth of 34 in. The cycling time between profiles was usually 15-2 minutes, although the sampling interval was reduced to about 1 minutes over a smaller depth range when energetic mixing events or hydrographically interesting features were observed. The RSVP (Fig. 1) is a tethered, freefall profiler about 1.4 in long, equipped with sensors for measuring pressure, P, microscale velocity shears, u,(=- 49u/'9z) and v.,(=- avl&), temperature, T, and conductivity, C. The probe length is a compromise between ease of deployment and resolution of low-wavenumber velocity structure. The average fall rate is about.7 ms-1, constrained by a drag element consisting of an annular brush near the rear of the probe during descent, but able to slide towards the RSVP's nose for improved retrieval dynamics. The raw data sampling rate during CEAREX was 256 Hz for all channels. was measured with a Thermometrics FP7 thermistor, which projects 1

9 forward from the probe nose assembly. This thermistor has an approximately flat frequency response to 2 Hz. Conductivity was measured with a Neil Brown Instrument Systems (NBIS) conductivity cell mounted on the side of the probe,.15 in above the probe tip. For salinity determination a second Thermometrics FP7 thermistor was mounted adjacent to the conductivity sensor. The NBIS cell has a response length of (.1) m [Gregg, et al., 1982], so that at the nominal fall rate the time constant of the conductivity cell is.14 s. Post-analysis of the conductivity data indicated a small time varying calibration offset voltage: conductivities have therefore been corrected by comparison with CTD data, kindly provided by J. Morison. Vertically averaged salinity, S, is determined from similarly filtered T and C: the spatial separation of the thermistor and conductivity cell is accounted for by lagging the temperature signal by.3 s, about.2 in, determined by an empirical search for minimized salinity spiking in a region with low dissipation rates. This lag is consistent with the physical separation of the two sensors. With the optimum lag for T incorporated, the effective resolution for S and density, at, is about.2 in. Least significant bit resolutions of the raw (256 Hz) 16-bit records are about 1.5 x 1-4 C in temperature, and 1.5 x 1-5 S m-1 in conductivity. Velocity microstructure was measured with two orthogonally mounted airfoil shear sensors on the RSVP's nose. These probes [Osborn and Crawford, 198] have a spatial resolution of about.3 in, sufficient to resolve most of the "universal", or Kolmogorov, shear spectrum for typical oceanic dissipation rates. Estimates of the turbulent kinetic energy dissipation rate, e, were made for approximately 1.4 in depth intervals by integrating the velocity shear spectra in the wavenumber range of 2 to 2 cpm. Assuming isotropy of velocity fluctuations in this wavenumber band, 15 (uz -f- vz) e= v 2 2 (1) where v is the kinematic viscosity of seawater, about 1.8 x 1-6 m2 s-1 at these low temperatures. Obvious spikes on the shear channels due to impacts with biota and other particles are edited prior to calculating shear variance: a further check is carried out by comparing the variance, skewness and kurtosis from the two shear probes, and discarding the higher variance if any of the above moments of the shear distribution seem un-realistic. 2

10 The noise level based on measured microscale shears in the quietest regions appears to be about 1-9 Wkg-1, substantially higher than during AIWEX [Padman and Dillon, 1987]. We believe that this is due to a change in the dynamics of the RSVP, which in CEAREX was an air-filled, pressure-sealed case compared with an oil-filled instrument in AIWEX. The probable result of the latter change, which was compensated for by a reduction in the number and size of drag and buoyancy elements near the instrument's tail, is an increase in motion near the instrumented nose. However, typical dissipation rates in turbulent patches were 1+3 times greater than the noise level, so that the mixing processes which contribute most to the time-averaged evolution of the large-scale hydrographic fields are well resolved. The noise level was lowest in regions where the thermal gradients were smallest, notably in the warm, almost isothermal Atlantic layer slab which was sampled at the end of the experiment. This suggests that the shear probes' thermal response, discussed by Osborn and Crawford [198] and Padman and Dillon [1987], may also contribute to setting the noise level on dissipation rate measurements. An upper limit on fully resolved shear spectra is set by the finite response length scale of the airfoil shear probes. The Kolmogorov shear spectrum contains energy at all scales larger than the Kolmogorov microscale: lk = (V3/E)1/4 (2) although the spectral peak occurs at wavelengths of about 11k. For E = 1 x 1-6 m2s-3, lk is about.1 in, and the peak spectral density lies at wavelengths of about.1 in. Some correction can be made for the finite response of the shear probes, however in all the data presented in this report, the correction to E is less than 3%, which is less than the potential calibration errors on the probes themselves. B: Description of Data The data shown in this report are divided into 5 sections. Section 1 shows the drift track of "" camp overlaid on the local bathymetry, and provides a table of hourly interpolated camp positions, derived from approximately hourly satellite fixes. The original data was provided by M. McPhee. The bathymetry is based on a chart from Jackson et al. 3

11 [1984], updated with along-track bathymetry collected during the "" Camp drift by D. Farmer and D. Menemenlis (Institute of Ocean Sciences, Sidney, B.C., Canada). Section 2 lists the start time of each microstructure profile. In the third section, we present profiles of temperature, T, salinity S, density, Qt, and turbulent kinetic energy dissipation rate, e, selected at approximately 4-hour intervals throughout the experiment. Basic features common to all profiles are a surface layer which is almost homogeneous in T, S and at, and a temperature maximum near 25 m which represents the extension of the West Spitzbergen Current into the Arctic Basin. The surface layer has a temperature of about C, which is close to the freezing point for the measured salinity of about psu. The Atlantic layer core has a temperature of above 2 C in almost all profiles. The fourth section presents contour plots of T, S, at and e, with the entire experiment to each page. A 4-hour filter has been applied to this data for plotting clarity. The final section provides the same data at 5 days per page, with a 1-hour temporal filter. 4
