Krill (Euphausia superba) distribution in relation to water movement and phytoplankton distribution off the northern South Shetland Islands
surveyed to investigate mechanisms for the formation of krill concentrations and to estimate acoustic ... biomass of krill in the 1990/91 austral summer. Main krill concentrations occurred in the shelf waters ... north of the islands, as usual. Tracks of drifting buoys (with curtain drogues at 30 m depth where krill ... for krill.)

A "one-way" interaction model is developed, in which krill ... indicate that variability in the annual recruitment of krill results in predator populations being less ... resilient to krill harvesting than deterministic evaluations would suggest. However, the analyses also raise ...
