East Antarctic ice stream tributary underlain by major sedimentary basin
Marine and rift sediments exert a fundamental control on ice stream flow in the West Antarctic Ice Sheet, and hence on its mass balance and stability. In contrast, most ice […]

340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core
Read more of: 340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice corePrecipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of the Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular Mode (SAM) and […]

Missing link in the Southern Ocean: sampling the marine benthic fauna of remote Bouvet Island
Read more of: Missing link in the Southern Ocean: sampling the marine benthic fauna of remote Bouvet IslandBouvet (Bouvetøya) is a geologically young and very remote island just south of the Polar Front. Here we report samples taken during the RV “Polarstern” cruise ANTXXI/2 on 3 days […]

Dynamic geomagnetic rigidity cutoff variations during a solar proton event
Read more of: Dynamic geomagnetic rigidity cutoff variations during a solar proton eventSolar proton events (SPE) are major, though infrequent, space weather phenomena that can produce hazardous effects in the near-Earth space environment. A detailed understanding of their effects depends upon knowledge […]

Albatross populations in peril? A population trajectory for black-browed albatrosses at South Georgia
Read more of: Albatross populations in peril? A population trajectory for black-browed albatrosses at South GeorgiaSimulation modeling was used to reconstruct Black-browed Albatross (Diomedea melanophris) population trends. Close approximations to observed data were accomplished by annually varying survival rates, reproductive success, and probabilities of returning […]

Temporal-spatial stability of competition in marine boulder fields
Read more of: Temporal-spatial stability of competition in marine boulder fieldsDemonstrable examples of marine interference-competition on ecological, and particularly evolutionary, time-scales have been highly confined in space. However, studies of such competition across large-scale space are conversely mere ‘snapshots’ in […]

Spatial and temporal variation in shallow seawater temperatures around Antarctica
Read more of: Spatial and temporal variation in shallow seawater temperatures around AntarcticaThe variability of Southern Ocean sea-surface temperatures (SST) are important to understanding coastal biology yet are poorly known amongst biologists. We compare sea temperatures at a constant depth (10–20 m) […]

Diversity and distribution of Victoria Land biota
Read more of: Diversity and distribution of Victoria Land biotaUnderstanding the relationship between soil biodiversity and ecosystem functioning is critical to predicting and monitoring the effects of ecosystem changes on important soil processes. However, most of Earth’s soils are […]

A molecular phylogeny of antarctic chironomidae and its implications for biogeographical history
Read more of: A molecular phylogeny of antarctic chironomidae and its implications for biogeographical historyThe chironomid midges Belgica antarctica, Eretmoptera murphyi (subfamily Orthocladiinae) and Parochlus steinenii (subfamily Podonominae), are the only Diptera species currently found in Antarctica. The relationships between these species and a […]

Sleep and circadian phase in a ship’s crew
Read more of: Sleep and circadian phase in a ship’s crewNumerous factors influence the increased health risks of seamen. This study investigated sleep (by actigraphy) and the adaptation of the internal clock in watch-keeping crew compared to day workers, as […]
