Antarctic Glacier Melting Due to Undersea Ice Ridge Rather Than Climate Change

polar ice1

Scientists from the British Antarctic Survey believe that a deepsea ice ridge is behind it melting more rapidly.

An underwater ridge could explain why a major glacier in the Antarctic is melting more quickly than ever before, according to a new study.

The Basket Star is a bloodless creature that weighs 11 pounds and lives for about 35 years

Amazing pictures of Southern Ocean marine life captured by scientists working in the Antarctic were released today.  The inhabitants of the continent’s seas were captured as part of a study on biodiversity carried out by the British Antarctic Survey (BAS).

Tracking Penguins From Space

Tracking Penguins From Space

This satellite image shows white Antarctic ice stained brown by Emperor penguin guano  

Satellite images have picked up giant red-brown stains on the pristine white sea ice, indicating the presence of thousands of penguins.

It meant that researchers for the British Antarctic Survey were able to locate every colony on the continent for the first time ever.

Another All Time Low For Arctic Ice

Another All Time Low For Arctic Ice 

 Picture is comprised of Envisat ASAR mosaics of the Arctic Ocean and highlights the changes in sea ice between June and mid-August 2008. The dark grey color represents ice-free areas while blue represents areas covered with sea ice.

Following last summer’s record minimum ice cover in the Arctic, current observations from ESA’s Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.

Sea Creatures In Antarctic Pounded By Icebergs

Sea Creatures In Antartic Pounded By Icebergs 

 Large red sea spider walking over white hydroid at 25 m. Antarctic sea spiders can be up to 500mm across and have up to 12 legs.

Antarctic worms, sea spiders, urchins and other marine creatures living in near-shore shallow habitats are regularly pounded by icebergs. New data suggests this environment along the Antarctic Peninsula is going to get hit more frequently. This is due to an increase in the number of icebergs scouring the seabed as a result of shrinking winter sea ice. The results are published this week in the journal Science.
