New data obtained by NASA's Operation IceBridge program is shedding new light on how ice sheets in Greenland are changing.
According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer.
According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years.
In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed.
After the ancestors of modern day Native Americans left Asia, they spent approximately 10,000 years living in the shrubby lowlands of the Bering land bridge, according to genetic and environmental evidence.
The Ross Sea is a major, biologically productive ecosystem in the Antarctic, which "clearly will be extensively modified by future climate change" in the coming decades as longer periods of ice-free open water are created by rising temperatures and changing wind patterns.
Previous instances of rapid thinning of Pine Island Glacier suggests that current ice loss in the Antarctic could continue for several more decades, a team of geologists from the US, UK and Germany report in this week’s edition of the journal Science.
Earth’s reflectivity (albedo) is on a much faster decline than previously estimated due to the retreat of sea ice in the Arctic Ocean. A key instrument incorporated on several NASA satellites has revealed significant data on this profoundly concerning issue.
Researchers writing in the journal Nature say that ocean warming could be causing a four-fold increase in ice loss on the Greenland Ice Sheet.
Researchers from the University of Washington and the German Space Agency (DLR) say that a Greenland glacier is slipping off into the ocean at a speed never before seen.
The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
