The Permafrost Young Researchers Network (PYRN) is hosting its kick-off meeting at the Abisko Scientific Research Station, Sweden on the 22nd to 24th of February 2007. PYRN (www.pyrn.org) is an international effort under the patronage of the International Permafrost Association (IPA) to bring young permafrost researchers together during the international polar year and beyond. The first phase of the PYRN project saw more than 300 young researchers from 31 countries join the network. It rapidly became the largest young researcher-driven network in the field of cryospheric science. PYRN offers, news, information and support to its members. It has sent 17 monthly newsletters since its start in 2005, maint...

If you're a lover of the novels of Magnus Mills, then you may have read his Explorers of the New Century, in which two rival expeditions traverse distinctly polar terrain. The expeditions are vying to be the first to arrive at the "Agreed Furthest Point" (AFP), the point furthest from civilization. Imagine my surprise to find out that there actually is such a point in real life, called the Southern Pole of Inaccessibility — it's the point on the Anta...

The Arctic sea ice cover is undergoing significant climate-induced changes, resulting in a reduction in ice extent and a net thinning of the sea ice cover. During IPY researchers from 10 nations will be studying the properties and processes that govern this sea ice cover and exploring its role as an indicator and amplifier of climate change. Numerous techniques will be brought to bear on this task, including expeditions, satellite remote sensing, autonomous rovers, buoys, ocean moorings, and numerical models.

During the IPY, the USGS will highlight numerous long-term studies of the polar regions on the state of the cryosphere (glaciers, permafrost, sea ice), the impacts of change over the last few decades, the petroleum resource potential of the Arctic, and the consequences of permafrost thawing on the Yukon River watershed in Alaska and Canada. Also, we will produce a high resolution Landsat mosaic image of Antarctica.

SCAR-MarBIN supports the Antarctic science community by giving free and open access to an unprecedented mass of data relevant to understand Southern Ocean biodiversity. SCAR-MarBIN will leave a valuable legacy for future generations, in the form of an information tool that will provide a baseline reference for establishing a State of Antarctic Environment, and predicting the future for marine communities around Antarctica, which are currently facing global change.

Plate tectonics and polar ocean gateways: The keys to understanding long-term global change Water mass exchange between world oceans is of great significance for long-term global climatic change and is controlled by tectonic and sedimentary evolution of oceanic gateways and basins. Reconstructions of the geological history of polar oceanic basins and gateways feed into computer simulations of climate change. PLATES & GATES is an international program focussing on the tectonic and sedimentary formation of those areas of the Arctic and Antarctica which are in particular critical for global change.

Microorganisms – including algae, bacteria, fungi and viruses – are numerically by far the most important group of organisms in polar aquatic ecosystems. As well as being the main drivers of biogeochemical cycles and the major producers and consumers of greenhouse gases, they are also sensitive barometers of environmental change. Yet very little is known about their role in ecosystems or their response to change. Working in both the Arctic and Antarctic with a broad range of techniques, including state-of-the-art molecular methods, this project will assess the diversity and make up of this microbial world. It will significantly advance understanding of the diversity and activity of these organisms and their role in climate and global environmental change.

ICESTAR & International Heliophysical Year (IHY) - Interhemispheric Conjugacy in Geospace Phenomena and their Heliospheric Drivers High energy particles from space generate the Aurora and illustrate why the polar regions are unique places for space research. Throughout IPY scientists from 22 countries, using instruments on balloons, ships, spacecraft and the ground will investigate how plasma and magnetic fields from the Sun affect near-Earth space and our atmosphere, improving our understanding of the impact of space weather on satellites, ground-based technology, terrestrial weather and climate.

Thermal State of Permafrost Permafrost conditions underlie upwards of 25% of the Earth's land surface. Permafrost temperatures are a function of past and present climates and vary greatly depending on location. Lacking is a comprehensive set of pemafrost measurements against which to assess present and future regional and global changes. Duirng IPY, TSP researchers will obtain a "snapshot" of permafrost temperatures in hundread of borehole throughout the world.
