18. December 2014: Microplastics in the ocean: biologists study effects on marine animals

Ingestion of microplastic particles does not mechanically affect marine isopods. This was the result of a study by biologists at the North Sea Office of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) that was published recently in the journal “Environmental Science and Technology”. The study marks the launch of a series of investigations aimed at forming a risk matrix on the sensitivity of different marine species to microplastic pollution.

20. November 2014: Permafrost soil is possible source of abrupt rise in greenhouse gases at end of last ice age

Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have identified a possible source of carbon dioxide (CO2) and other greenhouse gases that were abruptly released to the atmosphere in large quantities around 14,600 years ago. According to this new interpretation, the CO2 – released during the onset of the Bølling/Allerød warm period – presumably had their origin in thawing Arctic permafrost soil and amplified the initial warming through positive feedback. The study now appears online in the journal Nature Communications.

Ocean acidification - the evil twin of climate warming

Around half of the carbon dioxide volume discharged into the atmosphere through exhaust pipes and chimney stacks over the past two hundred years has been absorbed by the oceans - but not without consequence.
