Radio-echo sounding (RES) of polar ice sheets reveals extensive internal layering. The degree of continuity of internal layering holds critical information about the ice-flow field, but previous analyses of this […]
A 200-year proxy for northerly air mass incursions (NAMI) into central and western West Antarctica is developed from the examination of 19 shallow (21–150 m deep) Antarctic ice-core non-sea-salt (nss) […]
Few non-native species have colonized Antarctica, although increased human activity and accelerated climate change may increase their number, distributional range, and effects on native species on the continent. We searched […]
Rapid warming over the past 50 years on the Antarctic Peninsula is associated with the collapse of a number of ice shelves and accelerating glacier mass loss1, 2, 3, 4, 5, […]
The energetics of adult Streaked Shearwaters Calonectris leucomelas during the chick-rearing period were examined on Awa Island, Japan, in 2008 and 2009. Basal metabolic rates (BMR) were quantified using an […]
An interdisciplinary biostratigraphical study of Tournaisian–early Viséan sedimentary rocks from six sections in central Scotland has established the ranges of important palynomorph and ostracod taxa that can be used to […]
Snow moulds are fungi and fungal-like microbes that occur frequently as pathogens of moss and vascular plant species in the Arctic and Antarctic, chiefly in maritime areas with permanent snow […]
We investigated the relationships between fungal community composition, latitude and a range of physicochemical parameters in 58 soils sampled from a 2370 km latitudinal gradient between South Georgia (54°S, 38°W) […]
The transport of the AntarcticCircumpolarCurrent (ACC) varies strongly across the coupled GCMs (general circulation models) used for the IPCC AR4. This note shows that a large fraction of this across-model […]
If Southern Ocean plankton communities are changing in response to climate, biases in various nets need to be evaluated to help understand regional and temporal differences between historical and contemporary […]
Despite a widespread recognition of the role of seabird colonies in the fertilization of nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities […]
