Polar News and Notes Oceans

Aerial views of migrating land mammals are not that unusual today, but videos of migrating Arctic marine mammals were—until this past summer.  
A camera crew aboard a helicopter captured the summer migration of the narwhal, an elusive, medium-size whale, for a natural history unit of the British Broadcasting Company (BBC). According to a news story […]

March 18 will be the eighth quarterly Polar Day sponsored by the International Polar Year (IPY) organization to enable schools and other groups worldwide to join in celebration of polar research. The March theme is Polar Oceans.
Ocean-related activities will continue throughout the week of March 17-26. Resources provided by IPY include virtual balloon launches, activities […]

Even though they must have known they would be asked about the similarity to the title of a Beatles’ song, British researchers nevertheless painted a new robot submarine bright yellow. Denying the connection, an engineer said yellow makes it easy to spot the robot when it surfaces from under ice shelves in Antarctica. 
The seven-foot robot […]

The European Space Agency reports new rifts on the Wilkins Ice Sheet, which is connected to two islands by a strip of ice. The rifts could cause the largest ice shelf on the Antarctic Peninsula to destroy the strip, or bridge, of ice that has been preventing the shelf from breaking away.  
Wilkins Ice Sheet, […]

The World Conference on Marine Biodiversity, meeting in Valencia, Spain, in mid-November, received the fourth report on the Census of Marine Life, which is being compiled by 2,000 scientists from 82 nations. It will be officially released in October 2010.
This report revealed some amazing new findings about life in the ocean depths. In a […]

Stormy weather in the Arctic may have unanticipated effects on global warming, according to a new study by NASA. Researchers were looking to confirm a theory that a warming climate could cause an increase in storminess. They now believe it may be possible that new sinks for carbon dioxide may emerge from the relationship between […]

Well inside the Arctic Circle, scientists have found vents in the submerged Mid-Atlantic Ridge spewing out water as hot as 570 degrees Fahrenheit. This is the farthest north anyone has seen black smoker vents — so called because it appears as if dark smoke is billowing from them. In fact, the “smoke” is actually iron- […]

After three million years of being frozen out, mollusks and other marine creatures in the North Pacific will be able to move into the Arctic Ocean thanks to global warming. Researchers from the University of California and the California Academy of Sciences say warmer waters and ice-free conditions will likely allow Pacific species of mussels, […]

On May 26, 2008, published author Nancy Etchemendy will embark on the journey of a lifetime: the first of two research expeditions to Antarctica. On her blog, Etchmendy describes how an “unlikely series of events” resulted in an invitation to join the marine biology expeditions. The trip in May is a month-long voyage aboard the National […]

On April 17, the RSV Aurora Australis docked in Hobart, Australia, with what the chief scientist aboard called “a remarkable data set of observations from the Southern Ocean, covering a wide range of physical, chemical and biological variables.”
A team of scientists had spent the past four weeks on the research and supply vessel measuring ocean […]
