A Capstone of NSF-supported International Polar Year Deployments, AGAP Project May Help Determine What Caused Ice Sheet to Form Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a US-led international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice. ...

Recent observations of Arctic Ocean outflow in the Fram Strait suggest that freshwater is piling up in the Arctic Ocean. A change in wind direction could release the largest amount of freshwater through Fram Strait ever recorded. Photo: Rudi Caeyers The freshwater transport from the Arctic to lower latitudes is one of the main ways of the Arctic to interact with the global climate system. The effect of such a release of freshwater depends on the final magnitude and nature of the release. “The effects this release will have on the climate processes are in the focus of ongoing res...

Winnipeg, Canada — 18 February 2009 — The University of Manitoba-led project that gained worldwide appeal and interest will be one of the highlights of a conference in Europe Feb. 25, 2009 as International Polar Year (IPY) wraps. An IPY committee will release its State of Polar Research report at that time to summarize all the IPY studies, one of the largest of which was led by a climate change expert at the University of Manitoba. “Our data is coming in and our team is looking forward to the next phase of our research,” says Barber, David Barber, Canada Research Chair in Arctic System Science and director of the Centre for Earth Observation Science (CEOS) at the University of Manitoba. “IPY gave us this tremendous window into climate change. What we learned about...

February 17, 2009 — FAIRBANKS, Alaska — The Greening of the Arctic (GOA) IPY initiative is comprised of four projects each contributing to documenting, mapping and understanding the rapid and dramatic changes to terrestrial vegetation expected across the circumpolar Arctic as a result of a changing climate. These changes will likely affect the permafrost, active layer, carbon reserves, trace-gas fluxes, hydrological systems, biodiversity, wildlife populations and the human habitability of Arctic ecosystems, says GOA principal investigator Donald “Skip” Walker, director of the Institute of Arctic Biology’s ...

(c) National Science Foundation After years of planning, strategizing, and international discussions and debate, what once seemed to be only lofty scientific ambitions are now closer than ever to becoming a reality. Ever since subglacial lakes captured the imagination of scientists and the public more than a decade ago, researchers have dreamed of entering and sampling these alien environments to unlock secrets that might guide us in the search for life elsewhere in our solar system. The Scientific Committee on Antarctic Research’s (SCAR) Scientific Research Program (SRP) on Subglacial Antarctic Lake Envir...

Photo Credit - AGAP team There were many times in the last two months where it seemed that the Antarctic Continent would win, keeping hidden the extensive landscape of subglacial lakes and mountains beneath the several kilometers of ice on Dome A. All the advance planning and negotiating with program leaders and logistics groups for enough days in the field to run the airborne geophysics were of little importance once we arrived on Antarctica. At this point we were negotiating with the continent herself, and we learned she can drive a hard bargain! The group at AGAP S camp had anticipated...

Continuing his coverage of the 25th Chinese Antarctic Expedition, science journalist Jean de Pomereu reports on the departure of the Dome Argus (Dome A) traverse team from the Chinese Zhongshang Station in the Antarctic on the International Polar Foundation's SciencePoles website. On 18 December following an official departure ceremony, a team of 28 men left Zhongshang to start the 1,220 km traverse into the interior of Antarctica to Dome A, the highest point on the East Antarc...

In order to move work teams to the AGAP camps we must move everyone through the South Pole in order to acclimatize to the high altitude. This has presented a bottleneck of sorts, and along with other delays is putting the project considerably behind schedule. With equipment calibrated and people antsy to move out of McMurdo the next focus is how to move people through the next short stop at South Pole. A spreadsheet has been made and people have been moved back and forth on the sheet in response to weather delays and changing shifting. For days people have had bags sorted and checked waiting...

For several years we have been preparing for what seems an incredibly small window of a field season. Working as part of a six nation team we have coordinated our equipment, our personnel, our science plans, and our logistics until it seems we will even breath at the appropriate time! Our project, Antarctic Gamburtsev Province (AGAP), will map through the ice of the East Antarctic Ice Sheet, imaging the sleeping giant that lies below. This sleeping giant is a European Alp sized mountain range called the Gamburtsev Mountains, discovered 50 years ago by a team of Russian scientists as they traversed across this extensive ice sheet. Di...

Zhongshan Station serves as the logistical hub of Chinese scientific research activities in East Antarctica and in the near future it will be a support platform for the new Kunlun Station to be constructed at Dome A. Situated in a small ice-free coastal region between the ice sheet and the ocean, Zhongshan Station serves as a base for scientists conducting research at the station and out in the field. In his latest report, SciencePoles reporter Je...
