RAPID WARMING OF THE OCEAN AROUND SOUTH GEORGIA,SOUTHERN OCEAN, DURING THE 20TH CENTURY: FORCINGS, CHARACTERISTICS AND IMPLICATIONS FOR LOWER TROPHIC LEVELS
Abstract: The Southern Ocean is known to have warmed considerably during the second half of the 20th century but there are few locations with data before the 1950s. In addition, assessments of change in this region are hampered by the strong seasonal bias in sampling, with the vast majority of

LIFE HISTORY BUFFERING IN ANTARCTIC MAMMALS AND BIRDS AGAINST CHANGING PATTERNS OF CLIMATE AND ENVIRONMENTAL VARIATION
Abstract: The consequences of warming for Antarctic long-lived organisms depend on their ability to survive changing patterns of climate and environmental variation. Among birds and mammals of different Antarctic regions, including emperor penguins, snow petrels, southern fulmars, Antarctic fur

ENVIRONMENTAL FORCING AND SOUTHERN OCEAN MARINE PREDATOR POPULATIONS: EFFECTS OF CLIMATE CHANGE AND VARIABILITY
Abstract: The Southern Ocean is a major component within the global ocean and climate system and potentially the location where the most rapid climate change is most likely to happen, particularly in the high-latitude polar regions. In these regions, even small temperature changes can potentially

ECOLOGICAL REPERCUSSIONS OF HISTORICAL FISH EXTRACTION FROM THE SOUTHERN OCEAN
Abstract: A major mid-1980s shift in ecological structure of significant portions of the Southern Ocean was partially due to the serial depletion of fish by intensive industrial fishing, rather than solely to climate factors as previously hypothesised. Over a brief period (1969-1973), several

Histopathology of Antarctic krill, Euphausia superba, bearing black spots
Abstract: Small black spots have been noticed on the cephalothorax of Antarctic krill, Euphausia superba, since January, 2001. To study the nature of the black spots, the krill were sampled in the winter of 2003, 2006, and 2007 in the South Georgia region, the Antarctic Ocean. Histological

THE POWER OF ECOSYSTEM MONITORING
Abstract: 1. Implementing an ecosystem approach to fisheries management requires an effective ecosystem monitoring programme, the utility of which depends upon its ability (measured by the statistical power) to detect effects that trigger management action. 2. Using data from a long-term ecosystem

INTERANNUAL SPATIAL VARIABILITY OF KRILL (EUPHAUSIA SUPERBA) INFLUENCES SEABIRD FORAGING BEHAVIOR NEAR ELEPHANT ISLAND, ANTARCTICA
Abstract: We investigate the influence of krill (principally Euphausia superba) patchiness on the foraging distributions of seabirds to understand how variation in krill influences patch dynamics between krill and birds. At sea surveys were conducted near Elephant Island, Antarctica for three
