Mapping the Oceans with Seals

Posted by John Farrier in Science & Tech on October 8, 2010 at 4:17 pm

Oceanographers glued sensors to 57 seals and used their natural movements as a means of gathering information about Antarctic ocean conditions:

As the animals swim, the tags record information every few seconds, then relay it via satellite once the seals surface. About 30 percent of the time seals dive all the way to the bottom to forage for food, says Padman, so by studying enough dives for each animal — some 200,000 dives in total — the researchers can deduce where the seafloor lies.[...]

Other researchers might now be inspired to dig through seal data to see what features could be mapped, he adds. Ships can cost tens of thousands of dollars a day to operate in Antarctic waters, whereas there is a wealth of readily available information available on seal tags.

Kelpmania: Stunning and Spectacular Kelp Photography

Posted by Queuebot in Science & Tech on March 25, 2009 at 1:36 am


Kelp forests occur in cold, nutrient-rich water and are among the most beautiful and biologically productive habitats in the marine environment.

The coast of California, in particular, is home to one of the most spectacular kelp forests. Within the confines of this massive forest there lies an abundance of fishes, invertebrates and algae, marine birds and marine mammals.
