Wind-driven export of Weddell Sea slope water
The export of waters from the Weddell Gyre to lower latitudes is an integral component of the southern subpolar contribution to the three-dimensional oceanic circulation. Here we use more than […]

New geophysical compilations link crustal block motion to Jurassic extension and strike-slip faulting in the Weddell Sea Rift System of West Antarctica
Read more of: New geophysical compilations link crustal block motion to Jurassic extension and strike-slip faulting in the Weddell Sea Rift System of West AntarcticaGondwana breakup changed the global continental configuration, leading to opening of major oceanic gateways, shifts in the climate system and significant impacts on the biosphere, hydrosphere and cryosphere. Although of […]

Advection in polar and sub-polar environments: Impacts on high latitude marine ecosystems
Read more of: Advection in polar and sub-polar environments: Impacts on high latitude marine ecosystemsWe compare and contrast the ecological impacts of atmospheric and oceanic circulation patterns on polar and sub-polar marine ecosystems. Circulation patterns differ strikingly between the north and south. Meridional circulation […]

Macronutrient supply, uptake and recycling in the coastal ocean of the west Antarctic Peninsula
Read more of: Macronutrient supply, uptake and recycling in the coastal ocean of the west Antarctic PeninsulaNutrient supply, uptake and cycling underpin high primary productivity over the continental shelf of the west Antarctic Peninsula (WAP). Here we use a suite of biogeochemical and isotopic data collected […]

Evaluating the use of an object-based approach to lithological mapping in vegetated terrain
Read more of: Evaluating the use of an object-based approach to lithological mapping in vegetated terrainRemote sensing-based approaches to lithological mapping are traditionally pixel-oriented, with classification performed on either a per-pixel or sub-pixel basis with complete disregard for contextual information about neighbouring pixels. However, intra-class […]

Sensitivity of Pine Island Glacier to observed ocean forcing
Read more of: Sensitivity of Pine Island Glacier to observed ocean forcingWe present subannual observations (2009–2014) of a major West Antarctic glacier (Pine Island Glacier) and the neighboring ocean. Ongoing glacier retreat and accelerated ice flow were likely triggered a few […]

Broadband acoustic backscatter from crude oil under laboratory-grown sea ice
Read more of: Broadband acoustic backscatter from crude oil under laboratory-grown sea iceIn ice-covered seas, traditional air-side oil spill detection methods face practical challenges. Conversely, under-ice remote sensing techniques are increasingly viable due to improving operational capabilities of autonomous and remotely operated […]

Insights from the shell proteome: biomineralization to adaptation
Read more of: Insights from the shell proteome: biomineralization to adaptationBivalves have evolved a range of complex shell forming mechanisms that are reflected by their incredible diversity in shell mineralogy and microstructures. A suite of proteins exported to the shell […]

Climate change in the Kola Peninsula, Arctic Russia, during the last 50 years from meteorological observations
Read more of: Climate change in the Kola Peninsula, Arctic Russia, during the last 50 years from meteorological observationsThe authors provide a detailed climatology and evaluation of recent climate change in the Kola Peninsula, Arctic Russia, a region influenced by both the North Atlantic and Arctic Oceans. The […]

Genetic structure of Patagonian toothfish populations from otolith DNA
Read more of: Genetic structure of Patagonian toothfish populations from otolith DNAThe Patagonian toothfish, Dissostichus eleginoides, is a valuable fishery species and has a discontinuous distribution across the Southern Ocean. Identification of the genetic stock structure of toothfish would allow evaluation […]

Confirmation of EMIC wave driven relativistic electron precipitation
Read more of: Confirmation of EMIC wave driven relativistic electron precipitationElectromagnetic ion cyclotron (EMIC) waves are believed to be an important source of pitch angle scattering driven relativistic electron loss from the radiation belts. To date, investigations of this precipitation […]
