A visual classification was carried out of echo trace characteristics derived from 113 integration intervals of 1 n mi (nautical mile) each taken from the Southern Ocean in the area […]
The identification and quantification of Antarctic Pygoscelis penguin colonies depends increasingly on recognition of the characteristic optical properties of guano deposits, but almost all knowledge of these properties until now […]
Several very large synsedimentary slide units exist in the well-exposed Mesozoic fore-arc sequence of Alexander Island, Antarctica. The largest single exposure, which is at least 440 m thick and more […]
Convergent margins are areas of geological complexity. Basins which occur in the same position relative to a volcanic arc may owe their origin to more than one process of formation. […]
We studied the influence of sex of pup, maternal age, birth date of pup, number of foraging trips, and the mean duration of foraging trips at sea and nursing visits […]
The effect of maternal age and condition on the date of parturition and the duration of the perinatal period of Antarctic fur seals at Bird Island, South Georgia, were investigated […]
Larval fish assemblages are considered within the context of the unique ichthyofauna which evolved in Antarctic waters as a result of environmental cooling, glaciation, and isolation by the Antarctic polar […]
Geosat radar altimetry defines a pattern of closely spaced curvilinear gravity anomalies in the northern Weddell Sea and adjacent parts of the southwest Atlantic. These anomalies are caused by a […]
Understanding the mechanisms that link prey availability to predator behaviour and population change is central to projecting how a species may respond to future environmental pressures. We documented the behavioural […]
Polar oceans are poorly monitored despite the important role they play in regulating Earth’s climate system. Marine mammals equipped with biologging devices are now being used to fill the data […]
Cyclones are an important component of Antarctic climate variability, yet quantifying their impact on the polar environment is challenging. We assess how cyclones which pass through the Bellingshausen Sea affect […]
