Micro-plastic particles in edible fish and herbivores

According to recent AWI studies, plastic waste in the North and Baltic Seas is also eaten by edible fish and nautiluses

Micro-plastic particles pose a risk not only to sea birds, whales and organisms at the bottom of the sea. In two new studies, scientists of the Alfred Wegener Institute Hemholtz Centre for Polar and Marine Research (AWI) show that plastic waste is also eaten by nautili as well as North and Baltic Sea fish such as cod and mackerel.

The German research vessel Polarstern will arrive tomorrow in Cape Town after a five week voyage. During this training cruise from Bremerhaven to South Africa 32 international young scientists were trained in how to observe and measure the vital signs of the Atlantic Ocean.

Climate Change

Warm water is mixing up life in the Arctic

AWI researchers’ unique 15-year observation series reveals how sensitive marine ecosystems in polar regions are to change

The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from the Alfred Wegener Institute (AWI) have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water’s surface down to the deep seas. As the authors recently reported in the journal “Ecological Indicators”, that’s precisely what happened between 2005 and 2008.

Long-term Research

Loss of Diversity Near Melting Coastal Glaciers

Sedimentation is impacting an entire ecosystem on the seafloor

[13. November 2015] 

Melting glaciers are causing a loss of species diversity among benthos in the coastal waters off the Antarctic Peninsula, impacting an entire seafloor ecosystem. This has been verified in the course of repeated research dives, the results of which were recently published by international experts in a study in the journal Science Advances.
