How fish species suffer as a result of warmer waters

[05. January 2007] 

Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. This applies also to fish populations. Previous studies demonstrating a link between global warming and declining fish stocks were based entirely on statistical data. However, in order to estimate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is the key factor limiting the stock size of a fish species under heat stress.

Polarstern catches five tons of Marbled Antarctic Cod

[27. December 2006] 

One of Polarstern’s biggest fish catch in 24 years of research in Antarctic waters. New hope for commercial fisheries? Quite the opposite, a good catch doesn’t necessarily mean that depleted stocks have recovered.

Antarctic research within the International Polar Year IPY 2007/2008

[20. December 2006] 

The 27th research campaign of Bremerhaven’s Alfred Wegener Institute for Polar and Marine Research marks the beginning of the summer research season in the Antarctic. The institute collaborates with 20 research institutions and ten logistics organisations from 14 countries. Neumayer Station will serve as the logistical base for extensive measurements using aircraft. An expedition aboard research icebreaker Polarstern is travelling along the Antarctic Peninsula as part of the global ‘Census of Marine Life’, and at the Dallmann Laboratory activities will be focussing on Antarctic habitats as they undergo climate change. The Antarctic summer lasts from November to April. Many projects will be an overture to the International Polar Year 2007/2008.

Polarstern to explore uncharted seafloor

[24. November 2006] 

Atmospheric global warming has resulted in significant environmental changes on the Antarctic

Peninsula and throughout Western Antarctica. Glaciers are melting and the Larsen ice shelves are collapsing. An interesting consequence: areas which were previously covered by ice shelves several hundred meters thick are now accessible to researchers!
