Macroplastics at sea around Antarctica
More so than at any previous time, there is a heightened awareness of the amount of plastic in the environment, it’s spread to even remote localities and the multiple influences […]

Initialization of ice-sheet forecasts viewed as an inverse Robin problem
Read more of: Initialization of ice-sheet forecasts viewed as an inverse Robin problemAs simulations of 21st-century climate start to include components with longer timescales, such as ice sheets, the initial conditions for those components will become critical to the forecast. This paper […]

Emission of methane from plants
Read more of: Emission of methane from plantsIt has been proposed that plants are capable of producing methane by a novel and unidentified biochemical pathway. Emission of methane with an apparently biological origin was recorded from both […]

Post-breeding dispersal of Adélie penguins (Pygoscelis adeliae) nesting at Signy Island, South Orkney Islands
Read more of: Post-breeding dispersal of Adélie penguins (Pygoscelis adeliae) nesting at Signy Island, South Orkney IslandsARGOS satellite telemetry and Global Location Sensors (geolocators) were used to identify the moult locations and the winter foraging dispersal of Adélie penguins after they left their breeding colonies on […]

Pre-freeze mortality in three species of aphids from sub-Antarctic Marion Island
Read more of: Pre-freeze mortality in three species of aphids from sub-Antarctic Marion IslandUnderstanding the mechanisms by which aphids survive low temperature is fundamental in forecasting the risk of pest outbreaks. Aphids are chill susceptible and die at a temperature close to that […]

Antarctic clouds
Read more of: Antarctic cloudsSensitivity studies with global climate models show that, by their influence on the radiation balance, Antarctic clouds play a major role in the climate system, both directly at high southern […]

An analysis of cloud observations from Vernadsky, Antarctica
Read more of: An analysis of cloud observations from Vernadsky, AntarcticaThis paper presents results of a combined analysis of cloud observations made at the Antarctic base Faraday/Vernadsky between 1960 and 2005 and sea ice concentration from the HadISST1 data set. […]

The ECMWF model climate: Recent progress through improved physical parametrizations
Read more of: The ECMWF model climate: Recent progress through improved physical parametrizationsThe progress achieved since 2005 in simulating today’s climate with the European Centre for Medium-Range Weather Forecasts (ECMWF) model through improved physical parametrizations is described. Results are based on climate […]

Getting long in the tooth: a strong positive correlation between canine size and heterozygosity in Antarctic fur seals Arctocephalus gazella
Read more of: Getting long in the tooth: a strong positive correlation between canine size and heterozygosity in Antarctic fur seals Arctocephalus gazellaMost studies of heterozygosity-fitness correlations (HFCs) in natural populations relate to fitness traits expressed early in life, whereas traits that are often more difficult to measure such as longevity and […]

Source, timing, frequency and flux of ice-rafted detritus to the Northeast Atlantic margin, 30-12 ka: testing the Heinrich precursor hypothesis
Read more of: Source, timing, frequency and flux of ice-rafted detritus to the Northeast Atlantic margin, 30-12 ka: testing the Heinrich precursor hypothesisIncreased fluxes of ice-rafted detritus (IRD) from European ice sheets have been documented some 1000-1500 years before the arrival of Laurentide Ice Sheet (LIS)-sourced IRD during Heinrich (H) events. These […]

Wind-driven diversion of summer river runoff preconditions the Laptev Sea coastal polynya hydrography: Evidence from summer-to-winter hydrographic records of 2007-2009
Read more of: Wind-driven diversion of summer river runoff preconditions the Laptev Sea coastal polynya hydrography: Evidence from summer-to-winter hydrographic records of 2007-2009This paper examines the role of atmospheric forcing in modifying the pathways of riverine water on the Laptev Sea shelf, using summer-to-winter hydrographic surveys from 2007-2009. Over the two consecutive […]

A carryover effect of migration underlies individual variation in reproductive readiness and extreme egg size dimorphism in Macaroni Penguins
Read more of: A carryover effect of migration underlies individual variation in reproductive readiness and extreme egg size dimorphism in Macaroni PenguinsWhere life-history stages overlap, there is the potential for physiological conflicts that might be important in mediating carryover effects. However, our knowledge of the specific physiological mechanisms underlying carryover effects […]
