Episodic silicic volcanism in Patagonia and the Antarctic Peninsula: Chronology of magmatism associated with the break-up of Gondwana
Read more of: Episodic silicic volcanism in Patagonia and the Antarctic Peninsula: Chronology of magmatism associated with the break-up of GondwanaNew SHRIMP U–Pb zircon, Rb–Sr whole-rock, and 40Ar–39Ar data are presented for the Jurassic silicic volcanic rocks and related granitoids of Patagonia and the Antarctic Peninsula. U–Pb is the only […]

Salmonella in sub-Antarctica: low heterogeneity in salmonella serotypes in South Georgian seals and birds
Read more of: Salmonella in sub-Antarctica: low heterogeneity in salmonella serotypes in South Georgian seals and birdsThe number of human visitors to Antarctica is increasing rapidly, and with it a risk of introducing infectious organisms to native animals. To study the occurrence of salmonella serotypes in […]

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 […]

Exobiological prospecting
Read more of: Exobiological prospectingSeveral emerging technologies are being investigated for detecting potential extraterrestrial microbial life, either extinct and/or extant (living). These technologies are particularly relevant for future exobiological searches on Mars and Europa, […]

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 […]
