Brief Description (Abstract):

The oceans are subjected to great variations in space and time with regard to their physico-chemical and biological features. These changes are more pronounced latitudinally than longitudinally.In order to understand how these changes were reflected in the occurrence and abundance of zooplankton as a whole and the various groups in particular a series of zooplankton samples were collected during the Third Indian Expedition to Antarctica from the edge of the pack ice upto 20?S along an obli-que course between 22?56 E and 56?53 E. The area included the Antarctic Sub Antarctic and Subtropical zones where the surface water temperature ranged from 1 5?C to 27 5?C with striking variations at the Antarctic and Sub tropical convergences. The zooplankton obtained was subjected to volumetric and numerical analyses. For euphausiids besides the above gravimetric analys s was also done.

Status: Completed

Purpose: The zooplankton is an important tool in the study of biological oceanography. It changes its pattern of distribution and abundance in accordance with the changes in the environmental factors and consequent variations in the availability of food materials. These changes however, are more pro-nounced latitudinally than longitudinally. A north south course traverses through the main surface boundaries of the ocean and follow the principal temperature gradients. In view of these facts a lati-tudinal study of the occurrence and abundance of zooplankton with particular reference to euphausiids was taken up during the Third Indian Expedition to Antarctica in which the senior author was a parti-cipant.
