Brief Description (Abstract):

The report addresses preliminary results from the temperature and salinity profiles recorded by using XCTD probes deployed along the ship track from Prydz bay (68.69?S, 75.29?E) to India bay (69.26?S, 12.94?E) during the 28th Indian Scientific Expedition to Antarctica. The data was collected during 11th - 17th February 2009,onboard M. V. Emerald Sea. In the Prydz bay region, cold Antarctic Surface Water sinks to deeper depth near 70?E. This region is dominated by closed cyclonic gyre adjacent to the Amery Ice Shelf. Being a closed circulation, there is inflow of cold water from the east near the West Ice Shelf and outflow near Cape Darnley and due to its confined nature waters tend to be more salty in this region. In the India Bay region, high salinity is encountered with salinity range of 34.5 and above in regions where Circumpolar Deep Water is present.

Status: Completed

Purpose: The major objectives of this study are to (1) study interannual variability in thermohaline changes during the austral summer, (2) quantify the thickness of melt water associ-ated with melting of ice, (3) identify the water masses to characterize mix-ing, and (4) quantify the heat and salt content of the ocean. We attempt to address these by deploying expendable temperature, conductivity and depth probes (XCTDs) along the ship route between Prydz bay and India bay.
