Winds pushing Atlantic Ocean water into the Arctic control sea ice loss

Arctic Ice June 2010This article describes the current state of the Arctic sea ice and makes some predictions for the month ahead.  The predictions are based on my visual analysis of hundreds of satellite images.  I begin with some background and explanatory materials and then show how satellite images can be analyzed to show the mechanis

A new study led by researchers at Brown University offers fresh insights into the forces above and beneath the ocean surface that influence how sea ice moves and disperses in the Arctic Ocean, which is warming at over twice the rate of the global average.

A team of researchers from the University of Hawai'i at Mānoa (UH Mānoa) conducted a novel study on the world's deepest coral colonies in the waters of the Hawaiian Islands.

"The ice is clearly feeling the influence of the bottom of the ocean," says researchers Daniel Watkins.

The in-depth analysis reveals how local tidal currents strongly affect the movement of sea ice in the Arctic ocean and provides an unprecedented look at how the makeup of the seafloor is causing some of the most abrupt changes.

A recent Northern voyage on a Norwegian research vessel highlighted how soaring carbon dioxide levels and the resulting acidification of the oceans present an especially grave threat to the Arctic’s cold seas and the rich marine life that they harbor.
 

The cirrate octopus Cirroteuthis muelleri plunges to the seafloor to feed and leaves behind octagonal imprints, scientists suggest.

Researchers using ROVs found that Dumbo octopuses migrate to the seafloor to feed, leaving octagon-like marks on the sludge. This behavior has ecological implications for the deep-sea environment.

The discovery of environmental DNA from fish species that have strayed far from their normal range is an ominous reminder of warming, changing seas.
