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.

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."

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.

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.

Climate of the Arctic and its role for Europe/Arctic System Reanalysis The overall objective of IPY-CARE (International Polar Year - Climate of the Arctic and its Role for Europe) is to create, co-ordinate and prepare a Pan-European science and implementation plan for Arctic climate change and ecosystems research programme as contribution to the International Polar Year.

The Sixth Continent Initiative aims to introduce scientists from countries who have no experience in Antarctica to the research which is carried out there, during the IPY 2007, as a reaffirmation of the provision of the Antarctic Treaty that dedicates the continent to peace and science for all mankind.

Informing, educating and involving the next generation is vital to the success of IPY. The YSC is committed to maximizing the benefit of IPY for the world’s youth through youth involvement and youth-focused education and outreach information. Some YSC projects include an international youth conference (2008), an educational website (on-going) and a joint expedition series to both poles (2007-2008).

"Antarctic Sea Ice in IPY is the coordinated project for the sea ice zone surrounding Antarctica, covering over 20 million sqkm (the size of South America) at maximum extent. Our purpose is to determine, for the first time, the circumpolar year-round sea ice thicknesses in this zone. This effort requires extensive ship investigations, coordinated satellite monitoring and use of underwater technologies such as up looking sonar from moorings and use of unmanned autonomous underwater vehicles. The reflectivity or albedo of the earth's surface represents one of the main determinants of surface temperature and, Antarctic sea ice as one of the most large-scale changeable sources of reflected solar energy therefore represents a major contributor to climate and climate change."
