Simple models are used to assess the factors controlling near-surface winds over an Antarctic ice shelf. Observations from Halley Station and an automatic weather station situated close to the coastal […]
An alternative seismic source was investigated in an experiment conducted near Rothera Station, Antarctic Peninsula. The source was an airgun fired above the snow surface. Comparison shots using explosive and […]
The question is posed: “what limits the presence, distribution, and abundance of life in Antarctica?” Traditionally, continental isolation has been considered to restrict the arrival of new species and extreme […]
The effect of low temperatures and freeze-thaw stress on photosynthetic carbon exchange in an Antarctic population of the turf-forming moss species Polytrichum alpestre Hoppe was investigated using infra-red gas analysis. […]
We tracked eight adult northern lapwings Vanellus vanellus (six females and two males) from a Dutch breeding colony by light-level geolocation year-round, three of them for multiple years. We show […]
Arthrobacter alpinus R3.8 is a psychrotolerant bacterial strain isolated from a soil sample obtained at Rothera Point, Adelaide Island, close to the Antarctic Peninsula. Strain R3.8 was sequenced in order […]
The island of South Georgia is situated in the iron (Fe) depleted Antarctic Circumpolar Current of the Southern Ocean. Iron emanating from its shelf system fuels large phytoplankton blooms downstream […]
Glacial-state greenhouse gas concentrations and Southern Hemisphere climate conditions persisted until ∼17.7 ka, when a nearly synchronous acceleration in deglaciation was recorded in paleoclimate proxies in large parts of the […]
Tidal flexure in ice shelf grounding zones has been used extensively in the past to determine grounding line position and ice properties. Although the rheology of ice is viscoelastic at […]
