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...

February 18 — Scientists have become increasingly concerned about the potential impacts of climate change on the East Antarctic Ice Sheet, the largest remaining body of ice on Earth. They warn that ice filled basins within the ice sheet could melt in a warmer world and release large volumes of water into the sea, raising global sea levels. The ICECAP team has successfully completed the first of three field seasons in East Antarctica using an upgraded World War II-era DC-3. Photo: Jack Holt. See more photos.

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 ...

That’s because the first convoy of five huge equipment containers with the dri...

An IPY initiative extending field event helicopter support from February into April allowed scientists to find out what happens to aquatic ecosystems during the summer-winter transition. Small pond immediately after freezing. The thick carpet of microbial mat is very clear through the ice Antarctica is a continent with plenty of “water” but precious little in the liquid state that most life requires. Where liquid water does exist, microbial ecosystems develop that are oases of biological diversity in otherwise barren landscapes. One of the commonest type of liquid water habitat are small ponds that fr...

Circumpolar treeline research by the IPY core project PPS Arctic Fieldwork in Northern Norway: recording and mapping stand density, tree recruitment and age structure of Scots pine stand close to treeline. Photo: A. Hofgaard Are trees invading the Arctic? The ‘expected’ answer to this question is ‘Yes’: but is this really true? The expectation is based on some rather simple models that relate the position of the treeline to the local climate. In its simplest form, the idea is that it is too cold for trees to exist north of the present-day treeline, so a warming climate ought to p...

EBA is a complex interdisciplinary project involving over 40 research groups from approximately 22 nations, as well as links to the Arctic research community. Its work crosses traditional disciplinary divides within biology, in particular working across the marine and terrestrial realms. EBA has multiple aims reflected in its structure of 5 work packages. At a broad scale, these packages are aimed at understanding how the various ecosystems of Antarctica are structured and function, what historical processes have shaped them to be as they are now, what evolutionary processes have taken place in the Antarctic environment and, in turn, what that tells us about the environment itself. Finally, in the context of parts of Antarctica currently facing the fastest rates of environmental change on ...
