Ionospheric convection response to slow, strong variations in a northward interplanetary magnetic field: A case study for January 14, 1988
Read more of: Ionospheric convection response to slow, strong variations in a northward interplanetary magnetic field: A case study for January 14, 1988We analyze ionospheric convection patterns over the polar regions during the passage of an interplanetary magnetic cloud on January 14, 1988, when the interplanetary magnetic field (IMF) rotated slowly in […]

Control of near-surface winds over an Antarctic ice shelf
Read more of: Control of near-surface winds over an Antarctic ice shelfSimple 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 […]

Seismic characteristics of an airgun fired over snow
Read more of: Seismic characteristics of an airgun fired over snowAn 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 […]

Water as a limiting factor in the Antarctic terrestrial environment: a biogeographical synthesis
Read more of: Water as a limiting factor in the Antarctic terrestrial environment: a biogeographical synthesisThe 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 […]

Photosynthetic response of the Antarctic moss Polytrichum alpestre Hoppe to low temperatures and freeze-thaw stress
Read more of: Photosynthetic response of the Antarctic moss Polytrichum alpestre Hoppe to low temperatures and freeze-thaw stressThe 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. […]

Individuality in northern lapwing migration and its link to timing of breeding
Read more of: Individuality in northern lapwing migration and its link to timing of breedingWe 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 […]

Complete genome of Arthrobacter alpinus strain R3.8: biorediation potential unraveled with genomic analysis
Read more of: Complete genome of Arthrobacter alpinus strain R3.8: biorediation potential unraveled with genomic analysisArthrobacter 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 […]

Mechanisms of dissolved and labile particulate iron supply to shelf waters and phytoplankton blooms off South Georgia, Southern Ocean
Read more of: Mechanisms of dissolved and labile particulate iron supply to shelf waters and phytoplankton blooms off South Georgia, Southern OceanThe 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 […]

Synchronous volcanic eruptions and abrupt climate change ∼17.7 ka plausibly linked by stratospheric ozone depletion
Read more of: Synchronous volcanic eruptions and abrupt climate change ∼17.7 ka plausibly linked by stratospheric ozone depletionGlacial-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 […]
