Depth contours are in meters. While it has long been desirable to measure a suite of oceanographic parameters under an advancing ice field, this experiment was not designed to accomplish this. Mooring 3 met a similar fate on April 8, when it was dragged 2 km southward by the advancing ice. The ice did not reach the southernmost mooring. Wind velocity derived from atmospheric pressure and interpolated to a point midway between moorings 1 and 2.
North is along the y-axis.
This surface buoy was in slightly better condition, but all surface instruments had been damaged. On both moorings, however, the subsurface instruments escaped damage by ice and provided unique time series of temperature, salinity, and chlorophyll- a estimates underneath an advancing and retreating ice field. This paper focuses on the observations from the two sites that were within the ice field. In the next section we give a brief background of the region and then describe the mooring design, instruments, and data processing.
