BANGKOK, Thailand -- The polar oceans are not biological deserts after all.

A marine census released this week documented 5,500 species in the Arctic and 7,500 in the Antarctic, including several hundred that researchers believe could be new to science.

"The textbooks have said there is less diversity at the poles than the tropics, but we found astonishing richness of marine life in the Antarctic and Arctic oceans," said Victoria Wadley, a researcher from the Australian Antarctic Division who took part in the Antarctic survey. "We are rewriting the textbooks."

In one of the biggest surprises, researchers said they discovered dozens of species common to both polar seas -- separated by nearly 7,000 miles. Now they have to .......... http://www.adn.com/news/alaska/wildlife/story/693403.html

Crabbers get a boost in bairdi Tanner quotas

LAINE WELCH Image via Wikipedia FISHERIES Published: November 7th, 2009 10:10 PM Last Modified: November 7th, 2009 10:12 PM KODIAK -- Kodiak and Alaska Peninsula crabbers got some good news last week -- bigger catch quotas for bairdi Tanner crab, a mid-January fishery important to local economies.

Danish commandos 'monitoring hippies' on Arctic offshore rig #artcticloons

The environmental non-governmental group  Greenpeace  has published  statements and  video  showing its activists aboard two ships that are attempting to "interfere" with oil exploration going on in the Davis Strait, 100 miles west of Greenland. This business has in turn prompted the Kingdom of Denmark to launch two ships and a few helicopters to monitor the Greenpeace interference. The  Leiv Eriksson  is the source of all this Arctic bait and switch. British oil company  Cairn Energy  is attempting to drill four wells at depths of at least 5,000 feet this summer in "iceberg-strewn sea" with the 53,000-ton offshore oil rig, which has made its way to Arctic waters after a month of failed attempts by Green
