Geometry and development of glacial continental margin depositional systems in the Bellingshausen Sea
Read more of: Geometry and development of glacial continental margin depositional systems in the Bellingshausen SeaWe present multi-channel seismic (MCS) reflection profiles and bathymetry data acquired across a remote and poorly surveyed part of the Antarctic continental margin in the Bellingshausen and Amundsen Seas. This […]

Upper Cretaceous echinoids from James Ross Basin, Antarctica
Read more of: Upper Cretaceous echinoids from James Ross Basin, AntarcticaNew palaeontological collections made from Upper Cretaceous strata exposed within the James RossBasin, Antarctica, include ten echinoid species. Five species are described for the first time from Antarctica, while four […]

Rapid selection effects in a short-lived semelparous squid species exposed to exploitation: inferences from the optimisation of life-history functions
Read more of: Rapid selection effects in a short-lived semelparous squid species exposed to exploitation: inferences from the optimisation of life-history functionsThe short life span of cephalopods suggests a potential for high sensitivity to the artificial selective effects of human exploitation. To explore the effects of such selection life-history optimisation was […]

Glacier surge propagation by thermal evolution at the bed
Read more of: Glacier surge propagation by thermal evolution at the bedBakaninbreen, southern Svalbard, began a prolonged surge during 1985. In 1986, an internal reflecting horizon on radio echo sounding data was interpreted to show that the position of the surge […]

Can we predict the duration of an interglacial?
Read more of: Can we predict the duration of an interglacial?Differences in the duration of interglacials have long been apparent in palaeoclimate records of the Late and Middle Pleistocene. However, a systematic evaluation of such differences has been hampered by […]

Frostbite and other cold injuries in the heroic age of Antarctic exploration
Read more of: Frostbite and other cold injuries in the heroic age of Antarctic explorationFrostbite and other cold injuries on the early polar expeditions were common. This paper explains how frostbite was described, prevented, and treated on the Antarctic expeditions of the heroic age, […]

Ice-shelf basal channels in a coupled ice/ocean model
Read more of: Ice-shelf basal channels in a coupled ice/ocean modelA numerical model for an interacting ice shelf and ocean is presented in which the iceshelf base exhibits a channelized morphology similar to that observed beneath Petermann Gletscher’s (Greenland) floating […]

Vomit or flush? Diet analysis using samples from spntaneous regurgitates or the water-off-load technique
Read more of: Vomit or flush? Diet analysis using samples from spntaneous regurgitates or the water-off-load techniqueSeveral methods, each with specific advantages and disadvantages, are frequently used to obtain diet samples from seabirds. The collection of regurgitates (REG) as well as samples from the stomach water-off-load […]

Behavioural mapping of a pelagic seabird: combining multiple sensors and a hidden Markov model reveals the distribution of at-sea behaviour
Read more of: Behavioural mapping of a pelagic seabird: combining multiple sensors and a hidden Markov model reveals the distribution of at-sea behaviourThe use of miniature data loggers is rapidly increasing our understanding of the movements and habitat preferences of pelagic seabirds. However, objectively interpreting behavioural information from the large volumes of […]

Southern Weddell Sea shelf edge geomorphology: Implications for gully formation by the overflow of high-salinity water
Read more of: Southern Weddell Sea shelf edge geomorphology: Implications for gully formation by the overflow of high-salinity waterSubmarine gullies are the most common morphological features observed on Antarctic continental slopes. The processes forming these gullies, however, remain poorly constrained. In some areas, gully heads incise the continental […]
