Differences in backscattering strength determined at 120 and 38 kHz for three species of Antarctic macroplankton
Read more of: Differences in backscattering strength determined at 120 and 38 kHz for three species of Antarctic macroplanktonThe ability to acoustically separate zooplankton species is an important requirement for ecological studies and to improve biomass estimates. In order to distinguish between Euphausia superba and other swarm-forming macroplankters […]

Interpretation of acoustic data at two frequencies to discriminate between Antarctic krill (Euphausia superba Dana) and other scatterers
Read more of: Interpretation of acoustic data at two frequencies to discriminate between Antarctic krill (Euphausia superba Dana) and other scatterersA 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 […]

What colour is penguin guano?
Read more of: What colour is penguin guano?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 […]

Giant slide deposits from a Mesozoic fore-arc basin, Alexander Island, Antarctica
Read more of: Giant slide deposits from a Mesozoic fore-arc basin, Alexander Island, AntarcticaSeveral 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 […]

Controls on sedimentation at convergent plate-margins
Read more of: Controls on sedimentation at convergent plate-marginsConvergent 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. […]

Factors affecting the growth rate and mass at weaning of Antarctic fur seals at Bird Island, South Georgia
Read more of: Factors affecting the growth rate and mass at weaning of Antarctic fur seals at Bird Island, South GeorgiaWe 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 […]

Effects of maternal age and condition on parturition and the perinatal period of Antarctic fur seals
Read more of: Effects of maternal age and condition on parturition and the perinatal period of Antarctic fur sealsThe 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 […]

Antarctic larval fish assemblages: a review
Read more of: Antarctic larval fish assemblages: a reviewLarval 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 […]

Seafloor spreading in the Weddell Sea and southwest Atlantic since the Late Cretaceous
Read more of: Seafloor spreading in the Weddell Sea and southwest Atlantic since the Late CretaceousGeosat 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 […]
