Coastlines’ contribution to climate change possibly underestimated

Erosion of permafrost coasts in the Arctic could vent major amounts of CO2

[07. November 2019] 

Permafrost coasts make up about one third of the Earth’s total coastline. As a result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. A new study published in the journal Geophysical Research Letters now shows that large amounts of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.

Tiny fossils reveal 25,000 years of carbon history in the Southern Ocean

Exploring regional differences in the exchange of carbon dioxide (CO2) between the atmosphere and ocean surface

[21. October 2019] 

A reconstruction of 25,000 years of South Ocean carbon chemistry, using micro-fossils buried in sediments, shows sub-Antarctic waters have played a key role in regulating atmospheric carbon dioxide since the Last Glacial Maximum (LGM). Chemical changes measured in micro-fossil shells, as well as sediments, showed that different regions of the Southern Ocean varied in terms of their circulation, chemistry and biological productivity during the last glacial-interglacial cycle. 

CCAMLR Annual Meeting

Negotiations on an MPA in the Weddell Sea

International Commission for the Conservation of Antarctic Marine Living Resources will meet in Hobart

[18. October 2019] 

At this year’s annual meeting, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) will continue its negotiations regarding the establishment of a Marine Protected Area (MPA) in the Weddell Sea. Experts from the Alfred Wegener Institute were instrumental in preparing the application for the European Union (EU), which was submitted in 2016. In addition to the EU and its Member States, Norway has since joined as a co-supporter.

MOSAiC expedition

Distributed Network successfully deployed

Complex system of buoys and measurement instruments is drifting in the environs of Polarstern

[16. October 2019] 

One central task during the first phase of MOSAiC has been completed. An international team of scientists  successfully deployed the so-called Distributed Network. This is the complex system of buoys and measurement instruments that is now drifting in the environs of Polarstern.
