The Arctic Ocean environment is undergoing tremendous changes over the last decreased with shrinking sea ice cover and increased freshwater run-off and coastal erosion. The documentation of the current state of Arctic marine biological diversity is urgently needed to understand and evaluate the impact of climate change. The Arctic Ocean Diversity project (ArcOD) is an international collaborative effort to inventory biodiversity in the Arctic's three realms (sea ice, water column and sea floor) from the shallow shelves to the deep basins.

Integrated Communication, Education and Evaluation: A Clearinghouse and Coordinating Effort for IPY EOC Working with education and communication experts around the world, we will help coordinate and add value to IPY education, outreach and communications (EOC) activities, linking to formal and informal science education networks and standards, leveraging existing talent and tools in order to help maximize the potential for IPY to serve as a catalyst for science education and awareness.

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."

Inter-discipline Survey along Prydz Bay, Amery Ice Shelf and Dome A The 2000km interconnected Prydz Bay-Amery Ice Shelf-Lambert Basin-Dome A (PANDA) section in Antarctica plays an important role in Antarctic mass balance, sea level and climate change. About thirty observation systems for glaciology, oceanography, geology/geophysics, sun-earth physics, atmospheric science and astronomy will be installed and implemented along the section by the international cooperative expeditions leading by China during IPY2007-2009 and beyond.

Because of their cold, dry and stable air, the polar regions are the finest locations on the planet for making frontline astronomical observations. AstroPoles is a 15-nation project to assess the astronomical conditions at four polar sites – Dome A and Dome C in Antarctica, and summit Station and Ellesmere Island in the Arctic. By measuring sky brightness, optical seeing, water vapour content and the meteorological conditions at these sites, AstroPoles will provide baseline data to assess what astronomical facilities could be built in the polar regions, and the kind of science they could tackle.

The overall focus of the ECOGREEN consortium is to establish the scientific basis for a long-term ecosystem-based management of marine resources in West Greenland. The West Greenland society relies almost entirely on marine resources for industrial as well as subsistence utilisation. Today, the West Greenland marine ecosystem is very productive and sustains fisheries which contribute 95% of Greenland’s total export value. The Greenland Marine ecosystem also sustains seals and whales who feed in the area during summer, and, from the entire North Atlantic, seabirds by the million find a critical winter habitat resource in the ice-free area. Human use of the West Greenland marine ecosystem presents a complex mosaic of small- and large-scale commercial fishing, as well as subsistence and recreational fishing and hunting.

Some of the most dramatic weather events – including spring thaws, sea ice movements and the strong winds and high seas associated with severe winter cyclones – occur in the polar regions, and being able to forecast these events more accurately is crucial for mitigating their impact on local communities, fisheries, wildlife, energy production and transport. Using satellite data, this 15-nation project will help design the next generation of observing networks that are needed to improve our ability to forecast “high impact” weather events in polar regions.

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.

The West Antarctic Ice Sheet is currently undergoing rapid change, in particular over the Amundsen Sea Emabayment (ASE) region, and this may lead to accelerated future sea-level rise. Previous aerogeophysical investigations over the Siple Coast reveal that the geology of the West Antarctic Rift System may strongly modulate the dynamics of fast-flowing glaciers that drain the West Antarctic Ice Sheet. But what are the interplays between the virtually unknown sub-ice geology and the apparently thinning and retreating ASE glaciers, such as Pine Island Glacier and Thwaites Glacier? We will utilise new airborne geophysical data collected by UK, US and German teams over the ASE region to provide a unique window on the lithospheric cradle for the West Antarctic Ice Sheet and to study the geodynamics of the largest glaciated rift system on Earth.
