Relationships of Antarctic krill (Euphausia superba Dana) variability with westerlies fluctuations and ozone depletion in the Antarctic Peninsula area
Abstract: The assessment of environmental processes controlling variability of Antarctic krill (Euphausia superba) is an important subject to clarify the Antarctic marine ecosystem. We have assessed variability of krill recruitment and stock density with hypothesised environmental factors. We

Krill population dynamics at South Georgia 1991–1997, based on data from predators and nets
Abstract: Central to understanding krill population dynamics is knowledge of their population structure. To examine this we used length-frequency distributions from 142 weeks of sampling (n= 23996 krill) of 3 predator species breeding at South Georgia and 12 weeks of sampling (n = 10 252 krill)

Environmental variability and the behavioural dynamics of Antarctic fur seals in the South Atlantic
Abstract: Variability in the reproductive performance of marine predators may be a result of physical forcing by large-scale oceanographic variability. Time lags, remoteness from the epicentre of a physical process and the simultaneous action of multiple physical processes often mean that it is

Antarctic fur seal (Arctocephalus gazella) pup growth rates obtained at Cape Shirreff, Livingston Island, South Shetlands: 1994/95 to 1997/98 (CEMP Index C2, Procedure B)
Abstract: Antarctic fur seal, Arctocephalus gazella, pup growth rates were measured using CEMP Standard Methods (C2- Procedure B) over four consecutive Austral summer season (1994/95-1997/98) at CEMP Site and SSSI N°32 Cape Shirreff, Livingston Island, South Shetlands. Every fortnight (15 days)
