Coats Land dolerites and the generation of Antarctic continental flood basalts
Read more of: Coats Land dolerites and the generation of Antarctic continental flood basaltsOn the basis of geochemical signatures, Mesozoic magmatism in Antarctica is divided into the Ferrar Magmatic Province and the Dronning Maud Land Province. The tholeiitic magmatism of the Ferrar Magmatic […]

The signature of Southern Hemisphere atmospheric circulation patterns in Antarctic precipitation
Read more of: The signature of Southern Hemisphere atmospheric circulation patterns in Antarctic precipitationWe provide the first comprehensive analysis of the relationships between large-scale patterns of Southern Hemisphere climate variability and the detailed structure of Antarctic precipitation. We examine linkages between the high […]

Precipitation regime influence on oxygen triple-isotope distributions in Antarctic precipitation and ice cores
Read more of: Precipitation regime influence on oxygen triple-isotope distributions in Antarctic precipitation and ice coresThe relative abundance of 17O in meteoric precipitation is usually reported in terms of the 17O-excess parameter. Variations of 17O-excess in Antarctic precipitation and ice cores have hitherto been attributed […]

Heat flux distribution of Antarctica unveiled
Read more of: Heat flux distribution of Antarctica unveiledAntarctica is the largest reservoir of ice on Earth. Understanding its ice sheet dynamics is crucial to unraveling past global climate change and making robust climatic and sea level predictions. […]

Distributional patterns of polychaetes across the Western Antarctic based on DNA barcoding and particle tracking analyses
Read more of: Distributional patterns of polychaetes across the Western Antarctic based on DNA barcoding and particle tracking analysesRecent genetic investigations have uncovered a high proportion of cryptic species within Antarctic polychaetes. It is likely that these evolved in isolation during periods of glaciation, and it is possible […]

Snow accumulation variability over the West Antarctic Ice Sheet since 1900: a comparison of ice core records with ERA-20C reanalysis
Read more of: Snow accumulation variability over the West Antarctic Ice Sheet since 1900: a comparison of ice core records with ERA-20C reanalysisThis study uses a set of 37 firn core records over the West Antarctic Ice Sheet (WAIS) to test the performance of ERA-20C reanalysis for snow accumulation and quantify temporal […]

Southern Ocean pteropods at risk from ocean warming and acidification
Read more of: Southern Ocean pteropods at risk from ocean warming and acidificationEarly life stages of marine calcifiers are particularly vulnerable to climate change. In the Southern Ocean aragonite undersaturation events and areas of rapid warming already occur and are predicted to […]

Jurassic high heat production granites associated with the Weddell Sea rift system, Antarctica.
Read more of: Jurassic high heat production granites associated with the Weddell Sea rift system, Antarctica.The distribution of heat flow in Antarctic continental crust is critical to understanding continental tectonics, ice sheet growth and subglacial hydrology. We identify a group of High Heat Production granites, […]

Snow densification and recent accumulation along the iSTAR traverse, Pine Island Glacier, Antarctica.
Read more of: Snow densification and recent accumulation along the iSTAR traverse, Pine Island Glacier, Antarctica.Neutron probe measurements of snow density from 22 sites in the Pine Island Glacier basin have been used to determine mean annual accumulation using an automatic annual-layer identification routine. A […]

Predicting ecological responses in a changing ocean: the effects of future climate uncertainty
Read more of: Predicting ecological responses in a changing ocean: the effects of future climate uncertaintyPredicting how species will respond to climate change is a growing field in marine ecology, yet knowledge of how to incorporate the uncertainty from future climate data into these predictions […]

The last glaciation of Bear Peninsula, central Amundsen Sea Embayment of Antarctica: Constraints on timing and duration revealed by in situ cosmogenic 14C and 10Be dating
Read more of: The last glaciation of Bear Peninsula, central Amundsen Sea Embayment of Antarctica: Constraints on timing and duration revealed by in situ cosmogenic 14C and 10Be datingIce streams in the Pine Island-Thwaites region of West Antarctica currently dominate contributions to sea level rise from the Antarctic ice sheet. Predictions of future ice-mass loss from this area […]
