Brief Description (Abstract):

Preliminary analysis of expendable CTD profiles collected during the 26th Indian Antarctic Expedition along the ship route from Durban to India Bay, Antarctica (Track-1) and Prydz Bay to Mauritius (Track-2) during February to March 2007 are discussed. Vertical thermohaline structure reveal that the northern and southern branches of Subantarctic Front on both Tracks merge; likewise, the Agulhas Retroflection Front (AF) and South Subtropical Front (SSTF) merge between 43? and 44?S on Track-2. The southern branch of the Polar Front (PF2) meanders by 550 km southward towards east. The Subtropical Surface Water, Central Water and Mode Water are located north of 43.5?S, while the Subantarctic Surface Water, Antarctic Surface Water, Antarctic Intermediate Water and Circumpolar Deep Water are encountered in the Antarctic Circumpolar Current (ACC) region.

Status: Completed

Purpose: Repeated hydrographic observations are required to compare and quantify changes in the hydrodynamics over a period of many years however, such observations are impractical because of the high costs of chartering research vessel. To overcome this problem, I have initiated a project to collect hydrographic data in the southwestern IO sector of the SO by using expendable CTD (XCTD) probes which can be launched from a moving ship.
