Abstract:
The authors considered the inter-annual variability of krill transport factors in the Scotia Sea analysing data from available meso-scale surveys covered the Scotia Sea. The subject of analysis were the geostrophic water masses circulation and krill transport factors, including variability of water masses (kg / m3) and krill biomass (g / m3) transporting across the survey area. Obtained estimates were compared with those from CCAMLR 2000 Survey. It was shown that the presence or absence of krill in subareas/SSMUs in the Scotia Sea is in a greater degree a reflection of the dynamics of krill geostrophic transport, and is not determined by the krill stock state or not determined by the influence of krill fishery.
