SCIENCE - Under-Arctic Ecosystem Discovery

"Beneath Arctic ice, scientists find an ecosystem never imagined" by Pete Spotts, Christian Science Monitor 6/7/2012

Scientists have discovered a vast pea-soup-green bloom of tiny plant-like marine organisms under Arctic Ocean ice. The bloom represents an enormous, and until now, unknown reservoir of food for marine life in frigid waters at the top of the world.

These waters, in sum, appear to be far more biologically productive than previously believed.

"This wasn't just any phytoplankton bloom," says Kevin Arrigo, a Stanford University marine scientist and lead author of the study. "It was literally the most intense phytoplankton bloom I've ever seen in my 25 years of doing this type of research" in oceans around the world.

The scientists sampled only a relatively small section of ice above the Arctic basin's continental shelves last summer. But the findings suggest that, where the mix of nutrients and sunlight are right, other areas around the basin could be highly productive as well, the researchers say.
