The Labrador Sea Deep Convection Experiment data collection
Between 1996 and 1998, a concerted effort was made to study the deep open ocean convection in the Labrador Sea. Both in situ observations and numerical models were employed with […]

Shedding new light on the life cycle of mackerel icefish in the Southern Ocean
Read more of: Shedding new light on the life cycle of mackerel icefish in the Southern OceanMackerel icefish have a widespread distribution in the Atlantic and Indian Ocean sectors of the low-Antarctic region. Biological characteristics differ considerably between populations in the southern Scotia Arc and those […]

Antarctic Peninsula climate variability and its causes as revealed by analysis of instrumental records
Read more of: Antarctic Peninsula climate variability and its causes as revealed by analysis of instrumental recordsClimate observations made since the mid twentieth century reveal that the Antarctic Peninsula is a region of extreme climate variability and change. The pattern of change is, however, both seasonally […]

The spatial coherence of interannual temperature variations in the Antarctic Peninsula
Read more of: The spatial coherence of interannual temperature variations in the Antarctic PeninsulaThe west coast of the Antarctic Peninsula is a region of extreme interannual variability in near-surface temperatures. Recently the region has also experienced more rapid warming than any other part […]

Validation of ECMWF sea level pressure analyses over the Bellingshausen Sea, Antarctica
Read more of: Validation of ECMWF sea level pressure analyses over the Bellingshausen Sea, AntarcticaSurface pressure measurements from instruments deployed on ice floes in the southern Bellingshausen Sea were used to assess the accuracy of European Centre for Medium-Range Weather Forecasts (ECMWF) analyses in […]

A model of marine ice formation within Antarctic ice shelf rifts
Read more of: A model of marine ice formation within Antarctic ice shelf riftsLarge rifts that open in Antarctic ice shelves are known to be filled by snow accumulations, ice shelf fragments, and sea ice. This work demonstrates how these rifts may also […]

Variable food absorption by Antarctic krill: Relationships between diet, egestion rate and the composition and sinking rates of their fecal pellets
Read more of: Variable food absorption by Antarctic krill: Relationships between diet, egestion rate and the composition and sinking rates of their fecal pelletsThe kinetics of food processing by zooplankton affects both their energy budgets and the biogeochemical fate of their fecal pellets. We sampled 40 schools of krill across the Scotia Sea […]

Antarctic macrozooplankton of the southwest Atlantic sector and Bellingshausen Sea: Baseline historical distributions (Discovery Investigations, 1928–1935) related to temperature and food, with projections for subsequent ocean warming
Read more of: Antarctic macrozooplankton of the southwest Atlantic sector and Bellingshausen Sea: Baseline historical distributions (Discovery Investigations, 1928–1935) related to temperature and food, with projections for subsequent ocean warmingSince the Discovery Investigations of the 1920s and 1930s, seawater temperatures have increased in the Atlantic sector by ∼1 °C; greater than the global mean rise. The aims of this […]

Population dynamics and production of Themisto gaudichaudii (Amphipoda, Hyperiidae) at South Georgia, Antarctica
Read more of: Population dynamics and production of Themisto gaudichaudii (Amphipoda, Hyperiidae) at South Georgia, AntarcticaThe population dynamics, individual growth rates and productivity of the hyperiid amphipod Themisto gaudichaudii were studied in Cumberland Bay, a fjord on the north-eastern coast of South Georgia. The study […]

Separating the Tristan albatross and the wandering albatross using morphometric measurements
Read more of: Separating the Tristan albatross and the wandering albatross using morphometric measurementsRecent taxonomic revisions of the Wandering Albatross sensu lato has resulted in four separate species, the rarest of which is the Tristan Albatross (Diomedea dabbenena). We present the first detailed […]
