GAPS: The Impacts of Oil and Gas Activity on Peoples in the Arctic
Oil and gas exploration that is coming to Canada’s North may bring benefits such as previously unheard of wealth to local communities, but it will also present new challenges to community infrastructure and traditional livelihoods. Fort Good Hope But how do you assess the pros and cons of increased development? That’s where GAPS: The Impacts of Oil and Gas Activity on People in the Arctic Using a Multiple Securities Perspective, comes into play. As its name suggests, the project is using a comprehensive and holistic approach to try to come up with some of the answers. We are giving particular priority to the human se...

Arctic sea ice will probably not recover
As predicted by all IPCC models, Arctic sea ice will most likely disappear during summers in the near future. However, it seems like this is going to happen much sooner than models predicted, as pointed out by recent observations and data reanalysis undertaken during IPY and the Damocles Integrated Project. On February 25, 2009, there will be a celebration in Geneva, Switzerland to officially close the 4th IPY that started on March 1st 2007 in Paris, France. It is not a surprise that one of the main topics of this 4th IPY was climate change, since the polar regions play a very important role in Earth's climate. This role is magnified by the combined effect of two main processes: one is due to the presence of greenhouse gases in the atmosphere trapping longwave solar radiat...

Circumpolar Flaw Lead System Study Celebrates with IPY in Geneva
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...

Changes in tundra greenness linked to sea-ice retreat and warmer land temperatures
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 ...

Are Trees Invading The Arctic?
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...

Evolution and Biodiversity in the Antarctic: EBA
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 ...

First Antarctic Subglacial Lake Entry on the Horizon
(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...
