Paleoclimate, Paleoclimate history of the Arctic
Although the Arctic occupies less than 5% of the Earth’s surface, it includes some of the strongest positive feedbacks in the climate system. Reconstructing the climate history of the Quaternary […]

Inter-year differences in survival of Atlantic puffins Fratercula arctica are not associated with winter distribution
Read more of: Inter-year differences in survival of Atlantic puffins Fratercula arctica are not associated with winter distributionMiniature geolocator loggers (Global Location Sensing, GLS) that provide daily locations of birds have revolutionised the study of winter ecology and migration patterns of seabirds. A long-term study of ringing […]

Reduced seasonality in elemental CHN composition of Antarctic marine benthic predators and scavengers
Read more of: Reduced seasonality in elemental CHN composition of Antarctic marine benthic predators and scavengersAt all but the lowest latitudes, photoperiod varies through the year, resulting in seasonal variation in coastal primary productivity. This leads to a pronounced seasonality in the physiology of most […]

Ice core methods, conductivity studies
Read more of: Ice core methods, conductivity studiesElectrical measurements of ice cores are used to obtain high time resolution records of past climate. The electrical conductivity method is sensitive to the acidity of the ice. The dielectric […]

Three-dimensional mapping by Cryosat 2 of subglacial lake volumes
Read more of: Three-dimensional mapping by Cryosat 2 of subglacial lake volumesWe analyze data acquired by the CryoSat-2 interferometric radar altimeter and demonstrate its novel capability to track topographic features on the Antarctic Ice Sheet. We map the perimeter and depth […]

Oceanographic observations at the shelf break of the Amundsen Sea, Antarctica
Read more of: Oceanographic observations at the shelf break of the Amundsen Sea, AntarcticaThe glaciers draining into the Amundsen Sea Embayment are rapidly losing mass, making a significant contribution to current sea level rise. Studies of Pine Island Glacier (PIG) in this region […]

Sustained retreat of the Pine Island Glacier
Read more of: Sustained retreat of the Pine Island GlacierWe use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and […]

Seismic stratigraphic record of the Amundsen Sea Embayment shelf from pre-glacial to recent times: Evidence for a dynamic West Antarctic Ice Sheet
Read more of: Seismic stratigraphic record of the Amundsen Sea Embayment shelf from pre-glacial to recent times: Evidence for a dynamic West Antarctic Ice SheetStudies of the sedimentary architecture and characteristics of the Antarctic continental margin provide clues about past ice sheet advance-retreat cycles and help improve constraints for paleo-ice dynamic models since early […]

Vertical Eddy Fluxes in the Southern Ocean
Read more of: Vertical Eddy Fluxes in the Southern OceanThe overturning circulation of the Southern Ocean has been investigated using eddying coupled ocean–sea ice models. The circulation is diagnosed in both density–latitude coordinates and in depth–density coordinates. Depth–density coordinates […]
