OASIS will study the chemistry in the air over the Arctic Ocean. The health of mammals and humans is at stake, and a future change in climate will undoubtedly introduce unknown changes. OASIS will make use of a variety of platforms (icebreakers, ice islands, buoys) to obtain year-round information on the behavior of such key chemicals as ozone, mercury, and carbon dioxide. As the nature and extent of snow and ice cover is changing OASIS will assess the associated impact on, and by, climate change, and the human and ecosystem impacts of these chemicals.

Global Warming will have a large impact on glaciers in the Arctic region. Sea level will be affected, and substantial changes can be expected in sediment and fresh water supplies to embayments and fjords. In GLACIODYN we study the dynamics of Arctic glaciers by means of field observations, remote sensing from satellites, and computer modelling. This will deliver tools to make more accurate predictions about future changes.

Trace metals iron, zinc, copper, manganese, nickel and cobalt are essential for every living cell and organism of our planet. Recently we discovered that algae in the Southern Ocean, the basis of the entire Antarctic food-chain up to penguins and whales, suffer from a lack of dissolved iron for their growth and CO2 fixation. The role of the other metals in Arctic and Antarctic oceanic waters is virtually unknown. We will quantify distributions, role and fate of several trace metals. Combination with key natural isotopes allows the unraveling of sources and turnover rates of these Trace Elements and Isotopes in waters and ice of the polar oceans.

POLar study using Aircraft, Remote sensing, surface measurements and modelling of Climate, chemistry, Aerosols and Transport (POLARCAT) "Aerosols have a large effect on radiation transmission in the Arctic troposphere, both directly and indirectly via clouds. POLARCAT will study transport to the Arctic of aerosols, as well as of air pollution more generally, from anthropogenic sources and boreal forest fires. It will address the effects of this pollution on atmospheric chemistry and climate. POLARCAT will use a large number of aircraft, a ship, a train, surface stations, as well as satellite data and numerical models. The first campaign, from 26 March - 19 April will use two aircraft based in Longyearbyen, Spitsbergen. Other campaigns in February 2008 and summer 2008 will follow with aircraft being based at various locations throughout the Arctic and in the boreal region."

The Greenland Ice Sheet is an outstanding archive of information about what the Earth’s climate was like in the past, and the water locked in its ice will have a major impact on sea level rise due to climate change. Because of this, understanding how Greenland will react to global warming is crucially important. By gathering seismic data, ice cores and using radar, laser ranging and echo sounders, this project will shed new light on the Greenland Ice Sheet and improve scientists’ ability to model how it will react to climate change.

PPS Arctic: Present day processes, Past changes, and Spatiotemporal variability of biotic, abiotic and socio-environmental conditions and resource components along and across the Arctic delimitation zone. PPS Arctic investigates the causes and consequences of changes in the circumarctic treeline zone, using fieldwork and remote sensing to study and model temporal and spatial aspects of ecological, social and cultural factors. Changes in the zone affect Arctic ecosystem processes, resource availability and the entire Arctic climate through changes in tree and shrub cover and in albedo, with global consequences.

Three terrestrial components of the cryosphere: snow cover, permafrost, and small glaciers will be studied as well as their interactions with society and potential feedbacks to the Global Earth System. Within each area of research the foci of studies will be on the models’ development and creation of conditions for seamless their implementation to improve understanding and projections of environmental change and to serve numerous practical applications.
