Entanglement of Antarctic fur seals Arctocephalus gazella in man-made debris at Bird Island, South Georgia during the 1993 winter and 1993/94 pup-rearing season
the fourth consecutive winter and sixth consecutive summer at Bird Island, South Georgia. In the 1993 ... winter the number of entangled seals was only 39% of the record 1992 total, but still 5 times the numbers ... in 1990 and 1991. Nearly all animals were juveniles, half with severe injuries and the proportion of ... females (40%) was the highest yet reported. The proportion of animals entangled in packaging bands was the ...

Circumpolar connections between Antarctic krill (Euphausia superba Dana) populations: Investigating the roles of ocean and sea ice transport
in the Southern Ocean. Krill have a close association with sea ice which provides access to a ... critical food source and shelter, particularly in the early life stages. Advective modelling of transport ... . Here we present Lagrangian modelling studies at the circumpolar scale that include interaction with sea ... ice.
