Cretaceous fossil wood and palynomorphs from Williams Point, Livingston Island, Antarctic Peninsula
Read more of: Cretaceous fossil wood and palynomorphs from Williams Point, Livingston Island, Antarctic PeninsulaTerrestrial palynofloras from two localities on Williams Point, Livingston, Island, contain angiosperm monocolpates and tricolpates and can be dated as Cenomanian-early Campanian. This fixes the age for a collection of […]

Relationship between heart rate and oxygen consumption during steady-state swimming in California sea lions
Read more of: Relationship between heart rate and oxygen consumption during steady-state swimming in California sea lionsHeart rate (fH) and rate of oxygen uptake (VO2) were measured in six subadult California sea lions Zalophus californianus while they were at rest and while they were swimming for […]

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 […]
