with increased melting at the edge releasing large quantities of fresh water and ice algae directly into the upper mixed layer of the ocean. These nutrient inputs supported a large spring algal bloom and a population boom of Antarctic krill, a...
Ice retreat in this region appears to have happened rapidly in the centre of the incised trough, evidenced by a lack of overprinting of the lineations at the trough mouth. At the margins of the trough uniformly spaced recessional moraines suggest ice retreated more gradually. We...
To put this into perspective, Antarctica has been one of the most mysterious continents for decades. It is the center of numerous conspiracy theories, and many researchers suggest there’s more to Antarctica than snow and ice. Actually, millions of years ago Antarctica was anything but ice. In...
The relief of the ice of the coastal region is more complex, with poorly dissected sectors of the edge of the ice sheet alternating with glacial tongues which are traversed by cracks and broad plains of shelf ice, above which rise sloping ice caps. The basic morphological structures of the ...
The enormous Antarctic is an un-colonized continent covered with ice, whereby the north Arctic is comprised of a frozen ocean at the North Pole, surrounded by land masses to the south of which some are heavily populated by humans. Once the domain of explorers who had fallen under its ...
study of Antarctica has been greatly hindered by the fact that nearly all of the continent is permanently covered with a thick layer of ice. However, new techniques such as remote sensing, ground-penetrating radar, and satellite imagery have begun to reveal the structures beneath the ice. ...
moisture falling from clouds to the surface of the Earth, usually as rain, snow, and ice. The amount of precipitation is always measured as water or rain equivalent so allowing for the fact that snow can have various structures and densities...
On the subject of glaciers, rather than the birdlife that can be seen around them, words – at least the ones that I can bring to mind – cannot describe the majesty of these towering structures. Even my pictures struggle to capture the grandeur and scale that the visitor experiences in Wi...
Structures from three different ages make up the base. The first one, known as the Old Pole, was built in 1956 and is made of wood. It was abandoned in 1975, and it’s under a thick layer of snow and ice. Access is forbidden for safety reasons. The Dome was built in the early ...
Complex structures identified within both the East Antarctic and Greenland ice sheets are thought to be generated by the action of basal water freezing to the ice-sheet base, evolving under ice flow. Here, we use ice-penetrating radar to image an extensive series of similarly complex basal ice...
