Specific Features of the Structure and Dynamics of Waters and Their Influence on the Distribution of Krill and Salpae in the Weddell and Scotia Seas in March-April, 1997-1998

We present the results of biological and oceanographic investigations performed in the Weddell and Scotia Seas within the framework of the first (January-June, 1997) and second (January-June, 1998) Ukrainian Antarctic marine expeditions. We reveal some regularities in the space distribution of the aggregations of krill and salpae depending on the abiotic (hydrophysical) environmental factors and discuss possible mechanisms promoting the formation of aggregations of krill and salpae in the Antarctic waters.[PUBLICATION ABSTRACT]
