Satellites and submarines give the skinny on sea ice thickness
This summer, a group of scientists and students - as well as a Canadian senator, a writer, and a filmmaker - set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. view more (2009-09-02)
Will lemmings fall off climate change cliff?
Contrary to popular belief, lemmings do not commit mass suicide by leaping off of cliffs into the sea. In fact, they are quite fond of staying alive. view more (2007-04-23)
Arctic climate under greenhouse conditions in the Late Cretaceous
New evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous - a period of greenhouse conditions - gives a glimpse of how the Arctic is likely to respond to future global warming. view more (2009-07-09)
Scientists expand understanding of how river carbon impacts the Arctic Ocean
Arctic rivers transport huge quantities of dissolved organic carbon (DOC) to the Arctic Ocean. The prevailing paradigm regarding DOC in arctic rivers is that it is largely refractory, making it of little significance for the biogeochemistry of the Arctic Ocean. view more (2008-02-13)
Climate scientists spotlight Arctic warming, plight of polar bears
A climate scientist at the University of Chicago and 30 of her colleagues from across North America and Europe are urging the U.S. Fish and Wildlife Service to list the polar bear as a threatened species because global warming is melting its sea-ice habitat. view more (2006-06-19)
Research around the North Pole
The German research vessel Polarstern has returned today to Bremerhaven from the Arctic Sea. It has cruised as the first research vessel ever both the Northeast and the Northwest Passages and thereby circled the North Pole. view more (2008-10-21)
First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active. view more (2008-01-21)
NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions. view more (2009-10-09)
Arctic ocean history is deciphered by ocean-drilling research team
Sediment cores retrieved from the Arctic's deep-sea floor by the Integrated Ocean Drilling Program's Arctic Coring Expedition (ACEX) have provided long-absent data to scientists who report new findings in the June 21 issue of Nature. view more (2007-06-21)
German research vessel Polartern discovers abandoned Russian station on ice floe
On August 16, 2004 early in the morning the German research vessel RV Polarstern discovered the remains of the abandoned Russian drifting ice camp North Pole-32 on an ice floe. The position of the floe was 82°16`N - 004°21`W. Three more or less intact barracks (one with antenna), one tent, two damaged barracks, two tractors, three larger... view more... (2004-08-20)
LIFE IN A FROZEN ENVIRONMENT-WHATS IN IT FOR US?
Life on the moons of Jupiter, and a source of healthy polyunsaturated fatty acids and low temperature enzymes that could even make washing powders work at low temperatures: The microbes that live in Antarctic sea ice may hold the answers to a host of everyday applications as well as revealing how life forms might be able to exist on frozen... view more...

Warming oceans threaten Antarctic glaciers
Scientists have identified four Antarctic glaciers that pose a threat to future sea levels using satellite observations, according to a study published in the journal Science. view more (2007-03-16)
Arctic climate models playing key role in polar bear decision
The pending federal decision about whether to protect the polar bear as a threatened species is as much about climate science as it is about climate change. view more (2008-03-12)
Sea level rise of 1 meter within 100 years
New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level - which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC. view more (2009-01-08)
Arctic Map plots new 'gold rush'
Researchers at Durham University have drawn up the first ever 'Arctic Map' to show the disputed territories that states might lay claim to in the future. view more (2008-08-06)
Scientists endure Arctic for last campaign prior to CryoSat-2 launch
An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible. view more (2008-05-12)
Melting Greenland Ice Sheets May Threaten Northeast United States, Canada
Melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada. view more (2009-05-28)
Where Does the North Pole Ice Come From? The Origin of the Northern Hemisphere Ice Age
Large areas of the Northern Hemisphere are currently covered with ice. This has, however, not always been the case. In the current issue of the science magazine "Nature", scientists from the GeoForschungsZentrum Potsdam (GFZ) and the Potsdam Institute for Climate Impact Research (PIK) present a possible solution for the oldest mystery of palaeo... view more...

Antarctic ice shelf retreats happened before
The retreat of Antarctic ice shelves is not new according to research published this week (24 Feb) in the journal Geology by scientists from Universities of Durham, Edinburgh and British Antarctic Survey (BAS). view more (2005-02-23)
Successful series of measurements in Arctic sea ice
The German Research Vessel Polarstern had to prove its ice breaking capabilities in Arctic waters to gain data on two series of long-term research measurements. After working in regions up to latitude 82° N, Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association will enter port in Reykjavik... view more...
