SMOS Versatility Offers Sea Ice Mapping
2011-12-21 04:27:20

ESA´s SMOS mission is proving to be extremely versatile. Not only does this pioneering satellite offer crucial data on soil moisture and ocean salinity, but it can also map the thickness of ice floating in the polar seas. The Soil Moisture and Ocean Salinity (SMOS) satellite carries an innovative passive microwave radiometer to capture images of ℠brightness temperature´. These images correspond to microwave radiation emitted from Earth´s surface and can be related to...

Large blooms of tiny marine plants flourish in Antarctic waters left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonization is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the...

U.S. scientists using satellite data and records from cold war submarine missions have found Arctic Ocean ice thickness has declined 53 percent since 1980. This summer, a group of U.S. and Canadian scientists and students set out from Resolute Bay, Canada, to check the Arctic Ocean ice. One of the scientists was Ron Kwok of NASA's Jet Propulsion Laboratory. Kwok, the space agency said, has long provided checkups on the health of arctic sea ice -- the frozen sea water floating within the...

At least 235 species are thriving in both the Arctic and Antarctic polar seas, according to the Census of Marine Life. Scientists found that species such as grey whales, birds, worms, crustaceans, and angelic snail-like pteropods exist at both poles. Dozens of species were separated by nearly 7,000 miles, they said. Researchers are currently conducting DNA tests to prove whether or not the species are identical, and if so, they want to determine where the species "originated and how they...

Officials said Wednesday that the Interior Department is accepting the recommendation from the U.S. Fish and Wildlife Service to protect the polar bear as a threatened species under the Endangered Species Act because of the decline in Arctic sea ice from global warming. The department made its decision after citing studies by its own scientists that the decline of Arctic sea ice off Alaska and Canada could result in two-thirds of the polar bears disappearing by mid-century. The decision...

By Michael McCarthy An astonishing array of wildlife has been unexpectedly found in one of the world's most hostile environments - the pitch-black, freezing extreme depths of the Southern Ocean surrounding Antarctica. More than 700 creatures new to science, ranging from crustaceans and molluscs to carnivorous sponges and free-swimming worms, have been discovered on a series of expeditions exploring the deep waters of the Weddell Sea. No fewer than 585 new species of crustacean were brought...
