We designed an experiment to see if turbulence induced by shear instability could be a mechanism. Using equipment readily available we completed an experiment from the Ice Island T-3. A sensor array of current meters and thermistors (described later on) was suspended beneath the sea ice of Colby Bay, T-3, and data were recorded for 37 days during March and April, 1970. Our goals were: 1) to compute vector differences among current meter records and correlate them with temperature differences among the thermistors; 2) to run a spectral analysis of current meter and temperature records for determination of the partitioning of energy between long and short periods; 3) determination of statistical coherence among the current meter records; and 4) determination of temporal and spatial (vertical) sampling necessary for studies of turbulent processes which may act within layers whether induced by shear instability or by breaking of internal waves.
