Crustal block origins of the South Scotia Ridge
The Cenozoic development of the Scotia Sea and opening of Drake Passage evolved in a complex tectonic setting with sea-floor spreading accompanied by the dispersal of continental fragments and the […]

Variety and distribution of diatom-based sea-ice proxies in Antarctic marine sediments of the past 2ka
Read more of: Variety and distribution of diatom-based sea-ice proxies in Antarctic marine sediments of the past 2kaAntarctic sea ice is an essential component of the global climate system. Reconstructions of Antarctic sea ice from marine sediment cores are a vital resource to improve the representation of […]

A database of marine macronutrient, temperature and salinity measurements made around the highly productive island of South Georgia, the Scotia Sea and the Antarctic Peninsula between 1980 and 2009
Read more of: A database of marine macronutrient, temperature and salinity measurements made around the highly productive island of South Georgia, the Scotia Sea and the Antarctic Peninsula between 1980 and 2009We present a database from substantial collections of macronutrient data made on 20 oceanographic cruises, primarily from around the island of South Georgia and the Scotia Sea. This sector of […]

Drainage and refill of an Antarctic Peninsula subglacial lake reveal an active subglacial hydrological network
Read more of: Drainage and refill of an Antarctic Peninsula subglacial lake reveal an active subglacial hydrological networkThe presence of subglacial lakes and subglacial hydrological networks under the East and West Antarctic ice sheets is now relatively well understood, whilst their influence on ice dynamics is the […]

Cretaceous magmatism in the Antarctic Peninsula and its tectonic implications
Read more of: Cretaceous magmatism in the Antarctic Peninsula and its tectonic implicationsPeriods of cessation, resumption and enhanced arc activity are recorded in the Cretaceous igneous rocks of the Antarctic Peninsula. We present new geochronological (LA-ICP-MS zircon U-Pb) analyses of 36 intrusive […]

Thermal history of the southern Antarctic Peninsula during Cenozoic oblique subduction
Read more of: Thermal history of the southern Antarctic Peninsula during Cenozoic oblique subductionApatite (U-Th)/He and apatite fission track thermochronology is used to constrain the cooling and uplift history of the southern Antarctic Peninsula where easterly-directed subduction of the Phoenix Plate, including ridge-trench […]

Spatiotemporal overlap of baleen whales and krill fisheries in the Western Antarctic Peninsula region
Read more of: Spatiotemporal overlap of baleen whales and krill fisheries in the Western Antarctic Peninsula regionIn Antarctica, abundant consumers rely on Antarctic krill for food, but krill are also the subject of a commercial fishery. The fishery overlaps in time and space with the foraging […]

Benthic silicon cycling in the Arctic Barents Sea: A reaction–transport model study
Read more of: Benthic silicon cycling in the Arctic Barents Sea: A reaction–transport model studyOver recent decades the highest rates of water column warming and sea ice loss across the Arctic Ocean have been observed in the Barents Sea. These physical changes have resulted […]

Magnetically driven flow in a liquid-metal battery
Read more of: Magnetically driven flow in a liquid-metal batteryWe investigate the flow within a liquid-metal battery induced by an externally imposed magnetic field, B-0. An analytical model for laminar flow is proposed and this is found to be […]

Mismatches in scale between highly mobile marine megafauna and marine protected areas
Read more of: Mismatches in scale between highly mobile marine megafauna and marine protected areasMarine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe in part to facilitate the conservation of marine megafauna under the assumption that large-scale […]

Variation in blood mercury concentrations in brown skuas (Stercorarius antarcticus) is related to trophic ecology but not breeding success or adult body condition
Read more of: Variation in blood mercury concentrations in brown skuas (Stercorarius antarcticus) is related to trophic ecology but not breeding success or adult body conditionMercury is a pervasive environmental contaminant that can negatively impact seabirds. Here, we measure total mercury (THg) concentrations in red blood cells (RBCs) from breeding brown skuas (Stercorarius antarcticus) (n […]
