A Vision for Earth System Research: Have Your Say

Bremerhaven, July 2nd 2009. A new measurement system for the detection of whales is used for the first time on board of the research vessel Polarstern. Whales are usually difficult to spot. On the one hand, they spend the greater part of their life under water. On the other hand, only a small part of their body can be seen when they surface, and this can even hardly be distinguished from the surrounding water. Visual sightings by marine mammal observers are therefore usually based on observations of the spout, the condensing and quite warm breathing cloud. It rises, depending on the whale species and wind conditions, between one metre and ten metres over the water surface and remains visible for only a few seconds. A thermal imaging camera specifically optimized for this purpose now uses t...

Why are diatoms so successful? Researchers from the Alfred Wegener Institute find hints to this question in the algae's evolution. Bremerhaven, June 25th. Diatoms play a key role in the photosynthesis of the oceans and are therefore intensively studied. Researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association together with international collaborators have made a new discovery regarding the diatoms' photosynthesis. It has so far been believed that diatoms have inherited their photosynthetic capabilities exclusively from red algae. The molecular biologists have now shown that a significant part of the diatoms' genes originates from green algae. The photosynthetic cellular structure of the diatoms, the plastids, therefore combi...

New record Arctic sea ice cover minimum? Climate researchers from Bremerhaven and Hamburg present new prognoses Bremerhaven/Hamburg, June 10th 2009. Climate researchers from the Alfred Wegener Institute for Polar and Marine Research and KlimaCampus of the University of Hamburg participate for the second time in an international scientific competition. Some of the most renowned climate research institutes worldwide fathom possibilities for seasonal prognoses of Arctic sea ice cover by means of different methods and climate models. The declared aim of all participants is to find the best method for reliable prognoses. The German researchers agree upon a continuing negative trend. Another critical minimum of Arctic sea ice is to be expected in the late summer of 2009. ...

Bremerhaven/Cologne June 2nd 2009. An international team of researchers from Russia, Germany, the USA and Austria has conducted a deep drilling programme in the utmost northeast of Russia during the last six months to retrieve several hundred metres of marine sediments, impact breccias and permanently frozen soil. These make new insights into the climate history of the Arctic, crater formation of the Elgygytgyn Lake and permafrost dynamics possible. A milestone has been reached at the beginning of May with the first results of the drilling campaign. The cores gained will help to answer crucial open questions of Arctic geology. At the utmost northern fringe of north-eastern Siberia, about 900 kilometres west of the Bering Strait and 100 km north of the Arctic Circle (67°30

L'intervention de Valérie PECRESSE à la conférence sur l'année polaire internationale organisée par le Sénat du France est disponible à www.enseignementsup-recherche.gouv.fr. «La France est aux avant-postes et reste un leader dans les activités scientifiques en milieu polaire», a souligné Valérie Pécresse lors du colloque de clôture de l'Année polaire internationale, qui s'est tenu le 14 mai 2009. À cette occasion, la ministre a annoncé la création de l'observatoire international de l'Arctique qui rassemblera l'ensemble de la communauté scientifique et aura le rôle d'une vigie ...

Documentary filmmaker Mark Terry, president of Polar Cap Productions, Inc., took a team to Antarctica last December and January to document the recent findings made by the world’s scientific community during International Polar Year. The documentary will focus on new discoveries made related to the ozone hole, the diminishing populations of penguins and other marine life, the greening of the world’s largest desert, warming temperatures, glacial melting and increased world sea level. Featuring interviews from polar scientists from Canada, the US, the UK, Ukraine and Russia, a global cross-section of research on climate change will be presented. One of these featured interviews will be with Dr. David Ainley, renowned...

Research aircraft Polar 5 finishes Arctic expedition Unique measurement flights in the central Arctic completed Bremerhaven, April 29th 2009. The Arctic campaign PAM-ARCMIP (Pan-Arctic Measurements and Arctic Climate Model Intercomparison Project) ended yesterday in Ottawa with the participation of the research aircraft Polar 5. The campaign which lasted four weeks yielded unique measurement data on sea ice thickness, trace gases, aerosols and meteorological parameters thanks to the great range of the aircraft and modern measurement equipment. We were out and about in mainly unchartered territory. Our most northerly position was 88°40' N. Flight operations of this kind require a high degree of proficiency and a lot of experience, reports Dr. Andreas Herber, ph...
