Climate change: warm bath for an ice sheet
Greenland is losing ice through glaciers that flow into deep fjords. New observations highlight the important fjord processes that supply warm ocean waters to the melting glaciers, and thereby affect […]

No evidence for genetic differentiation between Antarctic limpet Nacella concinna morphotypes
Read more of: No evidence for genetic differentiation between Antarctic limpet Nacella concinna morphotypesThe extent to which genetic divergence can occur in the absence of physical barriers to gene flow is currently one of the most controversial topics in evolutionary biology, with implications […]

The structure, biological activity and biogeochemistry of cryoconite aggregates upon an Arctic valley glacier: Longyearbreen, Svalbard
Read more of: The structure, biological activity and biogeochemistry of cryoconite aggregates upon an Arctic valley glacier: Longyearbreen, SvalbardGlacier surfaces support unique microbial food webs dominated by organic and inorganic debris called ‘cryoconite’. Observations from Longyearbreen, Spitsbergen, show how these aggregate particles can develop an internal structure following […]

Assessing the potential of multispectral remote sensing for lithological mapping on the Antarctic Peninsula: case study from eastern Adelaide Island, Graham Land
Read more of: Assessing the potential of multispectral remote sensing for lithological mapping on the Antarctic Peninsula: case study from eastern Adelaide Island, Graham LandThe results of lithological mapping using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data for the Wright Peninsula region of Adelaide Island, Antarctic Peninsula are compared with existing geological […]

Time series analysis of biologging data: autocorrelation reveals periodicity of diving behaviour in macaroni penguins
Read more of: Time series analysis of biologging data: autocorrelation reveals periodicity of diving behaviour in macaroni penguinsThe nature of how behaviour at one time step influences the next is of great interest to behavioural ecologists, but rarely used for comparisons between animals. Time depth recorders (TDR) […]

Continental scale Antarctic deposition of sulphur and black carbon from anthropogenic and volcanic sources
Read more of: Continental scale Antarctic deposition of sulphur and black carbon from anthropogenic and volcanic sourcesWhile Antarctica is often described as a pristine environment, there is an increasing awareness of the potential threats from local pollution sources including tourist ships and emissions associated with scientific […]

Swarms of diversity at the gene cox1 in Antarctic krill
Read more of: Swarms of diversity at the gene cox1 in Antarctic krillThe Antarctic krill, Euphausia superba, is an abundant and key species found in the Southern Ocean that forms dense, discrete swarms. Despite over three decades of research on Antarctic krill, […]

Comparison of the emergent behavior of a complex ecosystem model in two ocean general circulation models
Read more of: Comparison of the emergent behavior of a complex ecosystem model in two ocean general circulation modelsA state-of-the-art complex marine ecosystem model, PlankTOM5 2, simulating the distribution of five plankton functional types (PFTs, mixed phytoplankton, diatoms, coccolithophores, micro and mesozooplankton), was implemented separately in two medium […]

The statistics of natural ELF/VLF waves derived from a long continuous set of ground-based observations at high latitude
Read more of: The statistics of natural ELF/VLF waves derived from a long continuous set of ground-based observations at high latitudeThis paper analyses a unique set of continuous high-quality well-calibrated observations of natural ELF/VLF radio waves, in the range 0.3-10 kHz, made at Halley Research Station, Antarctica (76 degrees S,27 […]

Holocene isostatic uplift of the South Shetland Islands, Antarctic Peninsula, modelled from raised beaches
Read more of: Holocene isostatic uplift of the South Shetland Islands, Antarctic Peninsula, modelled from raised beachesWe present new isobases constraining the Holocene isostatic uplift of the South Shetland Islands, northern Antarctic Peninsula, based on evidence from raised shorelines. Holocene shorelines were described and surveyed at […]

Ocean-atmosphere heat fluxes at the Ronne Polynya, Antarctica
Read more of: Ocean-atmosphere heat fluxes at the Ronne Polynya, AntarcticaThe Ronne Polynya is a coastal polynya, a region of thin ice or open water in sea ice, caused by the offshore transport of the ice by strong winds from […]
