Characteristics of water flows in areas for Antarctic krill concentrations near the South Shetland Islands
Abstract: Water flows in harvestable areas for Antarctic krill (Euphausia superba ... . Convergent complex eddies were observed in harvestable areas on the shelf, while shear current was observed ... in those on the slope. Large-scale movements of the buoys suggest krill flux from the South Shetlands ... flows in areas for Antarctic krill concentrations near the South Shetland Islands Approval: Approved ...

Developing conceptual models of elements of the Antarctic marine ecosystem: Antarctic krill (Euphausia superba)
Abstract: A simple generalised conceptual life history model for Antarctic krill is developed ... based on observations and data from the literature. The model attempts to take into account the observed ... relationships between Antarctic krill and its biotic and abiotic environment.

Krill distribution related to water structure and dynamics on the South Georgia shelf in January 2000 (AtlantNIRO-BAS Core Programme 1999/2000)
• Juvenile krill of 30-36 mm length were observed in the shelf zone and larger specimens, including spawning ... Abstract: Research on water structure and dynamics, krill biomass assessment, biology ... in each box. Krill were distributed rather evenly throughout both boxes, but no dense concentrations were ... apparent. In the western box krill density was nearly 0.2 glm3 and in the eastern box was 1.8- 4.7 glm3 ...

Krill, salps and other dominant zooplankton taxa in the Elephant Island area during the 1997 austral summer
moderate krill abundance and lower recruitment success of the 1995/96 year class relative to that of 1994 ... promoted good krill recruitment. However winter 1996 was characterized by slightly below average winter ... 1996 sea-ice conditions. These observations strongly suggest that winter sea-ice extent greatly affects ... larval survival and recruitment even when krill spawning is relatively early. Salp abundance values ...
