A new study led by researchers from Durham University in the UK has found that the geometry of channels beneath an ice-sheet play a much stronger role in mitigating … [Read full article]
By looking at fossilised pollen found below a hundred feet of dense rock off the coast of Northern Antarctica, researchers have been able to reconstruct a climate record for the southern continent, and determine that the last remnant of Antarctic vegetation existed on the continents northern peninsula some 12 million years ago in a tundra landscape similar to that of northern Canada.
On the return of the Polarstern vessel of the Alfred Wegener Institute (AWI) for Polar and Marine Research in the German-based Helmholtz Association, scientists reported that organisms found in the Atlantic region of the Southern Ocean were not adapting quickly to changes in the environment.
A Duke University led team of researchers has observed a “super-aggregation” of humpback whales feasting on the largest swarm of Antarctic krill seen in more than 20 years, in Wilhelmina Bay, along the Western Antarctic Peninsula.
The Brunt Ice Shelf is located on the coast of northern Coats Land in Antarctica, and is pictured below lying against the Weddel Sea.
Stereotype would have us convinced that Antarctica is a white mass of snow 365 days a year. But summer on the Antarctic Peninsula allows a little bit of green to sprout and add beautiful contrast to what we thought we knew of the region.
And climate change is aiding this progress, for one plant in particular.
Icebergs have always been majestic objects, and just a little ill-defined, but new research is shedding more and more light on them. In a new discovery that has global implications scientists have discovered that icebergs drifting out to sea leave in their wake an increased level of chlorophyll which in turns increases carbon dioxide absorption.
The Envisat – Environmental Satellite – launched by the European Space Agency in 2002 captured this image using the Medium Resolution Imaging Spectrometer (MERIS) on 5 February 2011 of the … [Read full article]
