Polar predictions
In an effort to improve understanding of faunal evolution and its relationship to climate change, the PALEOPOLAR project is challenging existing theories about the Early Cenozoic era using an integrated, […]

Heating up the Holocene
Read more of: Heating up the HoloceneWith direct meteorological data on the Antarctic Peninsula only dating back to the 1950s, scientists must search elsewhere for climate change records of the distant past. A series of expeditions […]

Morphotypes of virus-like particles in two hydrothermal vent fields on the East Scotia Ridge, Antarctica
Read more of: Morphotypes of virus-like particles in two hydrothermal vent fields on the East Scotia Ridge, AntarcticaViruses from extreme environments are still largely unexplored and may harbor unseen genetic potential. Here, we present a first glance at the morphological diversity of virus like particles (VLPs) from […]

The effect of geometry on ice shelf ocean cavity ventilation: a laboratory experiment
Read more of: The effect of geometry on ice shelf ocean cavity ventilation: a laboratory experimentA laboratory experiment is constructed to simulate the density-driven circulation under an idealized Antarctic ice shelf and to investigate the flux of dense and freshwater in and out of the […]

Sardine cycles, krill declines, and locust plagues: revisiting ‘wasp-waist’ food webs
Read more of: Sardine cycles, krill declines, and locust plagues: revisiting ‘wasp-waist’ food webs‘Wasp-waist’ systems are dominated by a mid trophic-level species that is thought to exert top-down control on its food and bottom-up control on its predators. Sardines, anchovy, and Antarctic krill […]

Modelled trends in Antarctic sea ice thickness
Read more of: Modelled trends in Antarctic sea ice thicknessUnlike the rapid sea-ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic […]

Colony attendance and at-sea distribution of thin-billed prions during the early breeding season
Read more of: Colony attendance and at-sea distribution of thin-billed prions during the early breeding seasonProcellariiform seabirds have extreme life histories; they are very long-lived, first breed when relatively old, lay single egg clutches, both incubation and chick-rearing are prolonged and chicks exhibit slow growth. […]

Permafrost and snow monitoring at Rothera Point (Adelaide Island, Maritime Antarctica): implications for rock weathering in cryotic conditions.
Read more of: Permafrost and snow monitoring at Rothera Point (Adelaide Island, Maritime Antarctica): implications for rock weathering in cryotic conditions.In February 2009 a new permafrost borehole was installed close to the British Antarctic Survey Station at Rothera Point, Adelaide Island (67.57195°S 68.12068°W). The borehole is situated at 31 m […]

Sea salt as an ice core proxy for past sea ice extent: a process-based model study
Read more of: Sea salt as an ice core proxy for past sea ice extent: a process-based model studySea ice is a reflection of, and a feedback on the Earth’s climate. We explore here, using a global atmospheric chemistry-transport model, the use of sea salt in Antarctic ice […]

Deep sequencing of the mantle transcriptome of the great scallop Pecten maximus
Read more of: Deep sequencing of the mantle transcriptome of the great scallop Pecten maximusRNA-Seq transcriptome data were generated from mantle tissue of the great scallop, Pecten maximus. The consensus data were produced from a time course series of animals subjected to a 56-day […]
