A small, inconspicuous lichen, Acarospora cf. badiofusca, was discovered colonizing ironstained quartz mica schists on the lower slope of Manhaul Rock, a recently exposed nunatak on the McLeod Glacier, Signy […]
As Antarctic subglacial lake research progresses to in situ exploration an important topic is the lake’s probable gas concentration. Depending on hydrological setting, subglacial lakes may contain large amounts of […]
The Wilkes Subglacial Basin, in the hinterland of the Transantarctic Mountains, represents one of the least understood continental-scale features in Antarctica. Aeromagnetic data suggests that this basin may be imposed […]
Over the past decade, Australian, Norwegian and Russian marine surveys have collected integrated seismic, gravity and magnetic data in the southern Indian Ocean. The more than 350,000 line-km of new […]
The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica […]
High-resolution aeromagnetic surveys provide a geophysical tool to help image the subsurface structure of volcanoes and their tectonic framework. Here we interpret high-resolution aeromagnetic data and models for James Ross […]
A combination of 1555 magnetic susceptibility measurements from the Antarctic Peninsula between 65°S to 72°S (for which the raw data are made available), and petrological, structural and metamorphic data, has […]
The Antarctic geomagnetics’ community remains very active in crustal anomaly mapping. More than 1.5 million line-km of new air- and shipborne data have been acquired over the past decade by […]
Krill consumption by natural predators represents a critical link between surveys and models of standing krill biomass and the design of a sustainable krill fishery for the Scotia Sea. Antarctic […]
A high resolution surface topography Digital Elevation Model (DEM) is required to underpin studies of the complex glacier system on the Antarctic Peninsula. A complete DEM with better than 200m […]
To examine the general population trends of large whales in South Georgia waters, 2 opportunistic data sets of sightings of large whales from 1991 to 2010 around South Georgia were […]
