Latest Glaciology Stories
Earth's tropical climate history has been revealed in unprecedented detail – year by year, for almost 1,800 years – by two annually dated ice cores drawn from the tropical Peruvian Andes.
Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight.
The Arctic Ocean's ice cover shrank to its lowest extent on record last September at the end of the northern hemisphere summer. This continues a long-term trend diminishing the ice to about half the size of the average summertime extent from 1979 to 2000.
A growing number of studies have pegged global warming and climate change as a cause of sea ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario.
Have you been experiencing the coldest spring weather in recent memory? Scientists say it may be due to global warming and rapidly melting sea ice in the Arctic.
NASA has kickstarted another season of science flights over Greenland to perform research activity with Arctic ice sheets and sea ice.
Recent climate induced changes to Arctic polar bears’ environment is affecting their habits and ability to survive, with the bears having to rely more and more on internal fat reserves
The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion.
All living organisms rely on iron as an essential nutrient. In the ocean, iron’s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean’s food web.
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...
