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, ...

STELLA ANTARCTICA is a 9-nation IPY project to investigate the feasibility of establishing an observatory at Dome C in Antarctica – potentially the best astronomical site in the world. The team will conduct several small-scale astronomical experiments at Dome C, as well as holding international discussions that could pave the way for an ambitious, multi-million Euro observatory at Dome C.

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...

Because they are so many birds and so few observers around Antarctica, every observation matters. The recently launched marine biodiversity internet portal SCAR-MarBIN allows birdwatchers to directly upload their data, making them available to scientists as well as the general public. As top predators, birds are an important component of the Southern Ocean‘s ecosystem. They are part of the comprehensive effort of the Census of Antarctic Marine Life (CAML) to study the distribution and abundance of the Antarctic biodiversity. CAML is now using the SCAR MarBIN portal, developed at the Royal Belgian Institute for Natural Sciences by Claude De Broyer and Bruno Danis, to concentrate biogeographical data on bi...

Thousands of amphipods can reduce fish carcasses to bones, but these carrion experts are unexpectedly scarce in the area of the recently collapsed Larsen B ice shelf, where the Polarstern Expedition is currently conducting research Baited traps consistently used to provide good numbers of amphipods throughout the expedition, whether designed to catch them or targeting fish. “Traps are secured on a metal frame, equipped with a weight and buoys designed to cope with the high pressure at the sea floor, and then dropped to the bottom. After 48 hours, the vessel returns, triggering the traps' release from the weights via an acoustic signal sent from a transmitter. Within 15 to 30 minutes, depending on the water depth, the traps float to the surface and are recovered,” explai...

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.

Terrestrial ecosystems in Arctic and Antarctic: effects of UV light, liquefying ice, and ascending temperatures (TARANTELLA)

Predicted changes in climate and ozone concentrations in the Polar Regions make it critically important to understand how changes in key environmental factors influence polar terrestrial ecosystems via the modification of their individual but interconnected components.

Observational and experimental research on the effect of climate change and ozone depletion is affiliated to international research programmes including the EBA, Evolution and Biodiversity in the Antarctic project, SCAR in the Antarctic, and in the Arctic to ITEX, International Tundra Experiment as well as IGBP-GCTE.

TARANTELLA aims to coordinate these studies by focusing on the experimental approach, in both the Arctic, in collaboration with ITEX, and in the Antarctic.

A common methodology is used, the so-called Open-Top Chambers (OTC) or small greenhouses for temperature manipulations; for UV-B field research, UV-B supplementation (lamps) and/or UV-B exclusion (foils), are used to experimentally establish varied UV-B levels.

We will study the responses of the terrestrial, aquatic and glacial communities of organisms, including the microbes, at both poles to global environmental changes. Our key questions include (a) diversity and biogeography, (b) food webs and ecosystem evolution, and (c) links between biological, chemical, and physical processes in icy ecosystems. This is a huge collaboration involving 17 nations and a wide range of field work.
