Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. view more (2008-04-24)
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)
The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. view more (2006-02-21)
CU-Boulder study shows 53 million-year-old high Arctic mammals wintered in darkness
Ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a far milder climate than today that featured lush, swampy forests. view more (2009-06-02)
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)
The muskox suffered a loss of genetic diversity at the Pleistocene/Holocene transition
The tundra muskox, one of the few large northern mammals to have survived to the present day, saw its genetic diversity decrease greatly at the end of the Pleistocene period, around 10,000 years ago. view more (2005-10-06)
Arctic sea ice reaches minimum extent for 2009, third lowest ever recorded
The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2009-09-18)
Arctic sea ice diminished rapidly in 2004 and 2005
The Arctic Ocean's perennial sea ice, which survives the summer melt season and remains year-round, shrank abruptly by 14 percent between 2004 and 2005, according to a newly published study. view more (2006-09-14)
Arctic sea ice narrowly missed record low in winter 2007, says University of Colorado team
The maximum extent of Arctic sea ice in winter 2007 was the second lowest on satellite record, narrowly missing the 2006 record, according to a team of University of Colorado at Boulder researchers. view more (2007-04-05)
Arctic sea ice minimum shatters all-time record low, report University of Colorado scientists
Scientists from the University of Colorado at Boulder's National Snow and Ice Data Center said today that the extent of Arctic sea ice appears to have reached its minimum for 2007 on Sept. 16, shattering all previous lows since satellite record-keeping began nearly 30 years ago. view more (2007-09-21)
Arctic sea ice reaches lowest extent in 2008, second lowest ever recorded
The Arctic sea ice cover appears to have reached its minimum extent for the year, the second-lowest extent recorded since satellite record-keeping began in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center, or NSIDC. view more (2008-09-17)
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)
IARC scientists document warm water surging into Arctic
Scientists at the University of Alaska Fairbanks International Arctic Research Center this fall documented that recent surges of warm water from the North Atlantic Ocean continue to pulse into the Arctic Ocean and are moving toward Alaska and the Canadian Basin. view more (2006-09-27)
Media invitation: Arctic expedition may find clues to what caused the last ice-age
Invitation to a press conference on Thursday 3 June, 12.30pm at the Royal Society, 6 Carlton House Terrace, London SW1Y 5AG Scientists will soon be extracting the deepest Arctic sedimentary cores ever drilled from the Lomonosov Ridge, in the deep oceans more than 2,000 km off the coast of Norway. They will core to a depth of about 500 metres... view more... (2004-05-12)
Russia Returns To Arctic On A Drifting Ice-floe
After a long break Russia is getting ready to resume the research in Arctic with the help of floating stations. As Valery Martyshenko (Rosgidromet) has advised InformNauka, an appropriate ice-floe is currently being looked for, and the 32nd station will start the floating in the last decade of April. Vladimir Sokolov, Head of the SP-32 floating... view more... (2003-03-25)
Tracking Climate Change
DFG funds the first European drilling expedition to the North Pole In August 2004, a new and exciting chapter will be opened in the history of Arctic research. In the Arctic Coring Expedition (ACEX), three icebreakers will set off in the direction of the North Pole to extract cores from beneath the Arctic seafloor. By investigating marine... view more...

Arctic sea ice thinning at record rate
The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite. view more (2008-10-29)
Foxes get frisky in the far north
Bees do it, chimps do it- Now it seems Arctic foxes do it, too. New research looking at the DNA fingerprints of canids in the Far North has revealed that foxes once thought to be monogamous are in fact quite frisky. view more (2007-07-18)
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)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
