Comparison of temperature situation near South Georgia in December–February, 1989–1990, 1990–1991, 1999–2000 and 2000–2001 on satellite data and information about krill catches in Subarea 48.3

Monitoring of the sea surface temperature (SST) in Subarea 48.3 on satellite data (GOES-E, Meteosat), use of in situ data and the further analysis of the SST maps, maps of the SST anomalies and dynamics provide strictly special, but constant information on hydrological situation in the survey area. Analysis of this situation based on data obtained in expeditions, as well as literature and the CCAMLR materials could allow us to assess, with a certain degree of reliability, a potential situation of krill fishery in Subarea 48.3 for the entire coming year already by the summer season onset. Reliability of the krill fishery forecasts could be judged only by actual results of fishing activities under various hydrological conditions. This work is an attempt to perform such an analysis using a certain array of materials obtained in 1989-1991 and 1999-2001.
