On March 1 2007, students at schools around the world marked the advent of International Polar year by conducting an ice experiment. They then told the IPY community and the world by pinning a virtual balloon onto a web-based map showing exactly where they were. It proved to be quite a success, with hundreds of schools contributing so far. IPY enthusiasts also joined in, turning the map into a riot of red balloons. See the whole map here. For technical reasons, browsers don't like it if you show too many balloons at one time, so only the most recent 200 balloons are shown. However, you can see all contributed posts directly by browsing the directory from ...

The International Polar Year has begun. What a week! With US and UK launches on the Monday stirring up media attention, followed by an event in Portugal on the Wednesday and over 20 more national events on the day itself, March 1st 2007, we definitely hit the news! While traveling to Paris with Nicola, to prepare for the international launch, the phone didn't stop ringing, both sides of the Channel Tunnel and even on the Paris subway system! I was contacted by journalists as diverse as New Zealand Radio, an In-flight magazine, BBC World Service, Vatican Radio, Al Jazeera English, an Italian science magazine, Chinese TV networks, and Scientific American to name a few. During the International Ceremony itself, my phone kept shaking, and afterwards, on a tour of Paris, I saw ...

Thank-you to everyone who was involved with launch events, who launched virtual balloons, who launched real balloons (see the Swedish launch web-cast!), those behind the scenes, and those on stage. IPY Celebrations around the world on March 1st, and throughout this week, have been a huge success. You can watch those you missed on the Arctic Portal, or still launch your virtual balloon now, and throughout IPY, to recognise the importance of the polar regions to the whole planet. Here is a map showing balloons that have been launched around the world (you can zoom in on where you live or zoom out to see the world map!): ...

IPY launch events around the world can be viewed live at the Arctic Portal. We also encourage everyone to launch a virtual balloon and show how many people around the world care about the polar regions and are interested in IPY. Everyone is welcome to join in, young or old, polar or tropical! The Official Opening Ceremony takes place in Paris at 11am local time. That is UTC 10:00, or, 1am in Anchorage, 5am in New York, 7am in Santiago, 3.30pm in Calcutta, 7pm in Tokyo, and 9pm in Sydney. You can watch it live or after the event on the web at the Arctic Portal, where you will also find webcasts of other national launch events from around th...

Watch IPY launch events on-line at the Arctic Portal and elsewhere. Throughout this week, over twenty nations around the world are celebrating the launch of the International Polar Year 2007-2008. New Zealand, Indigenous People, Argentina, and the Ukraine have already held extremely successful events. This week, Monday will see Press and Participants gathering in London, Strasbourg, and Washington DC, and Portugal will be holding their kick-off event on Wednesday. Thursday is the big day, with the Global Launch occurring in Paris at 1000 UTC (1100 local Central European Time) and national celebrations in Australia, Brazil, Canada, China, Denmark, Greenland, Finland, France, Germany, Iceland, Italy, Japan, Norway, ...

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.

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.
