Arctic expeditions find giant mud waves, glacier tracks
Scientists gathering evidence of ancient ice sheets uncovered a new mystery about what's happening on the Arctic sea floor today. Sonar images revealed that, in some places, ocean currents have driven the mud along the Arctic Ocean bottom into piles, with some "mud waves" nearly 100 feet across. view more (2007-12-13)
Erosion Doubles Along Part of Alaska's Arctic Coast: Cultural and Historical Sites Lost
Coastal erosion has more than doubled in Alaska - up to 45 feet per year - in a 5-year period between 2002 and 2007 along a 40-mile stretch of the Beaufort Sea. view more (2009-02-19)
Riding the winds of change
The Inuit have spent thousands of years working and living in the Arctic. However, climate change is forcing them to change the traditional way of doing things. view more (2007-02-20)
Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)
Soviet plans implemented by Nature 90,000 years ago
One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time because of fears for the impact on the Arctic... view more... (2002-01-22)
Texas researchers and educators head for Antarctica
It's been more than 100 years since anyone has journeyed to this section of Antarctica's Amundsen Sea, but that is about to change. view more (2007-08-16)
The sea-ice is getting thinner - A closer look at the climate and ecosystem of the Arctic Ocean
Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001. view more (2007-09-14)
Arctic sea ice images derived from classified data should be made public
Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council. view more (2009-07-16)
Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
Arctic Ocean could be ice-free in summer within 100 years, scientists say
The current warming trends in the Arctic may shove the Arctic system into a seasonally ice-free state not seen for more than one million years. view more (2005-08-24)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

Expedition allows teachers to participate in polar research
What better way to engage students in science than to apply lessons learned from fieldwork? This is the philosophy of Alaska teachers participating in the Arctic Expedition for K-12 Teachers, a program organized by the International Arctic Research Center (IARC) at the University of Alaska Fairbanks and a handful of international agencies. view more (2006-09-14)
Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the land bridge thought to be the major route for human migration from Asia to the Americas. view more (2006-10-12)
Walrus Calves Stranded by Melting Sea Ice
Scientists have reported an unprecedented number of unaccompanied and possibly abandoned walrus calves in the Arctic Ocean, where melting sea ice may be forcing mothers to abandon their pups as the mothers follow the rapidly retreating ice edge north. view more (2006-04-14)
Unstated assumptions color Arctic sovereignty claims
Settling the growing debate over ownership of Arctic Ocean resources is complicated by the fact that the various countries involved have different understandings of the geography of the place. view more (2009-05-29)
Giant project to test Antarctic ice stability
If rising global temperatures cause the ice streams of Western Antarctica to break up, major cities and agricultural heartlands the world over would be submerged. Researchers from the University of Leeds' School of Geography are set to embark on a £1m, three-year project to find out exactly how stable they are. view more (2004-05-10)
Less Arctic ice means higher risks, experts warn
The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. view more (2007-10-29)
Mercury in Mackenzie River delta dramatically higher than previously believed
University of Alberta researchers conducting a water study in the Mackenzie River Delta have found a dramatically higher delivery of mercury from the Mackenzie River to the Arctic Ocean than determined in previous studies. view more (2009-06-17)
Subtropical Arctic
The North Pole, synonymous with all things very cold, once had a subtropical climate according to scientists now returning from the Arctic . view more (2004-09-06)
Global warming could lead to fast freeze, warns University of Ulster scientist
Dramatic climate change as a result of global warming could happen in a single lifetime - instead of being a slow process evolving over centuries, according to a University of Ulster academic. Professor Marshall McCabe of the School of Environmental Sciences said that given the right set of circumstances, "a climate can flip in a... view more... (2004-05-25)
