IARC scientists document warm water surging into Arctic

September 27, 2006
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.

Scientists made the observations this fall during an oceanographic cruise aboard the Russian icebreaker Kapitan Dranitsyn as part of the Nansen and Amundsen Basins Observational Systems program. Information gathered by the NABOS program, as well as from other international programs, has shown that, during the last decade, the movement of warm water into the Arctic Ocean has increased. And the readings from this fall's cruise show unprecedented warmth in some areas.

"The large area of the Arctic Ocean promises to become much warmer," said Igor Polyakov, NABOS principal investigator and a research professor at IARC.

The readings come from observational moorings, which are instrument-bearing buoys that are anchored to the ocean floor and float below the surface of the ocean. These instruments first detected a surge of anomalous warm water, at mid-ocean depths of about 150 to 800 meters below the surface, in February of 2004 on the continental slope of the Laptev Sea, Polyakov said. "What we found this year was one of our eastern moorings also showed a warming signal."

That finding indicates that the warm water is moving further and further into the Arctic, he said, which could increase the overall temperature of the Arctic Ocean. While the causes of the influx of warm water will require further study, the observations from the NABOS project suggest that the Arctic Ocean is moving toward a warmer state, a change that could have global implications.

Ocean temperature in the Arctic is important because it may affect the amount of sea ice in the region. Scientists believe that arctic sea ice cover plays a major role in the global climate, as ice reflects more of the sun's heat than open water.

The NABOS project is funded by the National Oceanic and Atmospheric Administration and the National Science Foundation and is a collaboration among six nations. It is one of many UAF projects that will contribute to the international efforts of the upcoming International Polar Year. IPY is a two-year event, slated to begin in March 2007, which will focus research efforts and public attention on the Earth's polar regions. UAF is among a handful of institutions worldwide that is ideally situated to participate in IPY research, education and outreach.

NSIDC, NASA Say Arctic Melt Season Lengthening, Ocean Rapidly Warming
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap's thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

The Longest Road: Overland in Search of America, from Key West to the Arctic Ocean
by Philip Caputo (Author)


In The Longest Road, one of America’s most respected writers takes an epic journey across America, Airstream in tow, and asks everyday Americans what unites and divides a country as endlessly diverse as it is large.Standing on a wind-scoured island off the Alaskan coast, Philip Caputo marveled that its Inupiat Eskimo schoolchildren pledge allegiance to the same flag as the children of Cuban immigrants in Key West, six thousand miles away. And a question began to take shape: How does the United States, peopled by every race on earth, remain united? Caputo resolved that one day he’d drive from the nation’s southernmost point to the northernmost point reachable by road, talking to everyday Americans about their lives and asking how they would answer his question.So it was that in 2011,...

Arctic Ocean Sediments: Processes, Proxies, and Paleoenvironment, Volume 2 (Developments in Marine Geology)

Arctic Ocean Sediments: Processes, Proxies, and Paleoenvironment, Volume 2 (Developments in Marine Geology)
by R. Stein (Author)


Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas....

The Arctic Marauder (Adventures of Jerome Plumier)

The Arctic Marauder (Adventures of Jerome Plumier)
by Jacques Tardi (Author)


Spectacular faux-woodcut vistas make Tardi’s groundbreaking “icepunk” story a retro classic. In its ongoing quest to showcase the wide range of Jacques Tardi’s bibliography, Fantagraphics reaches all the way back to one of his earliest, and most distinctive graphic novels: A satirical, Jules Vernes-esque “retro-sci-fi” yarn executed on scratchboard in a stunningly detailed faux-woodcut style perfectly chosen to render the Edwardian-era mechanical marvels on display. Created in 1972, The Arctic Marauder is a downright prescient example of proto-“steampunk” science fiction — or perhaps more accurately, and to coin a spinoff genre, “icepunk.”

In 1899, “L’Anjou,” a ship navigating the Arctic Ocean from Murmansk, Russia, to Le Havre, France comes across...
