Investigating the foraging ecology of seabirds is especially challenging given their wide-ranging movements and the practical difficulties of obtaining unbiased information on their feeding behavior. Despite the development of animal-borne […]
On RADARSAT imagery, the southern margin of the onset zone of Bindschadler Ice Stream, West Antarctica, manifests a multi-banded feature, with brightness varying across the bands and oscillating along each […]
Arctic terrestrial ecosystems are generally considered to be species poor, fragile and often isolated. Nonetheless, their intricate complexity, especially that of the invertebrate component, is beginning to emerge. Attention has […]
The circum-Antarctic clam Laternula elliptica (King & Broderip 1831) is the largest infaunal bivalve of the Southern Ocean. It mostly lives in water depths of less than 100 m (highest […]
Because of the lack of a definitive air link to an international gravity base station, the Antarctic Peninsula gravity network was originally, and still is, tied to the Potsdam gravity […]
Understanding the NOy budget at high latitudes is important for our knowledge of present-day clean air chemistry and essential for reliable interpretation of existing ice core nitrate data. However, measurements […]
New high-resolution aeromagnetic anomaly data from the central Antarctic Peninsula reveal a magnetic signature typical of a magmatic arc system. Analysis of the new aeromagnetic map, together with susceptibility data […]
The utility of aeromagnetic and other geoscientific compilations on a range of scales, is well established for a wide variety of geological investigations. Aeromagnetic compilations, currently underway for the Antarctic […]
Mesospheric winds are derived from HF radar observations of meteor echoes at Halley (76°S, 27°W), Antarctica. These meteor echoes are observed within the first range gates of the radar (less […]
Ice melts when it is in contact with ocean waters that have temperatures above the in situ freezing point. The product is a mixture of meltwater and seawater having properties […]
Studies of the Antarctic mesosphere, and its contrasts with the Arctic, are expected to hold the key to improved understanding of the mesopause region and energy and momentum transfer processes […]
This paper discusses predicted evolution patterns of present-day changes of ice thickness, surface elevation, and bedrock elevation over the Greenland and Antarctic continents. These were obtained from calculations with dynamic […]
