One Planet - Polar Summit: New Ocean Decade Programme announced for Antarctica

[10. November 2023]  In the context of the “One Planet - Polar Summit”, taking place on 8-10 November in Paris, France and hosted by the Paris Peace Forum, UNESCO announced the endorsement of a new major programme aimed at better understanding, protecting and sustainably managing the Southern Ocean and Antarctica in the framework of the UN Decade of Ocean Science for Sustainable Development 2021-2030 (‘Ocean Decade’).

7th Copernicus Ocean State Report

New finding on the development of phytoplankton

AWI researchers contribute long-term study to the 7th Copernicus Ocean State Report

[19. October 2023]  A team of experts from the Alfred Wegener Institute’s Physical Oceanography working group and led by Hongyan Xi presented the results of a long-term study in the recently released 7th Copernicus Ocean State Report (OSR7). The satellite data analysed by the team shows that, for the majority of phytoplankton groups in the Atlantic Ocean, the quantity has barely changed over the past 20 years. 

Dynamics of Antarctic sea ice in the past

New study sheds light on sea ice-ocean-climate interactions about 18,000 to 11,000 years ago

[16. October 2023]  The transition from the last glacial period to the current warm period was marked by major Antarctic climate warming and concomitant atmospheric CO2 rise at ~18,000–11,000 years ago, whose origin may lay in the Southern Ocean. A study by former AWI researcher Henrik Sadatzki reveals that the Antarctic sea ice cover declined substantially at the transition from the last glacial period to the current warm period, playing a key role in driving significant deglacial climate and atmospheric CO2 changes.

From Antarctica to 'the Moon'

EDEN ISS greenhouse returns to Bremen and has a new destination

[20. September 2023]  The Antarctic greenhouse EDEN ISS is back in Bremen after spending five years on the seventh continent amid ice, cold and polar nights. The greenhouse has carried out numerous plantings, with harvests totalling approximately one tonne of fresh vegetables for research, to supply the overwintering crews of Neumayer Station III that is operated by AWI.

How does the Elbe affect the German Bight?

Helmholtz researchers are the first to comprehensively analyse the transport of climate gases, environmental chemicals, nano- and microplastic, and nutrients from the Elbe to the North Sea.

[30. August 2023]  The Elbe transports contaminants, stemming from industry, agriculture, and water treatment plants, to Germany’s North Sea coast. Their concentrations vary due to inlets found along the course of the river, but also due to degradation and sedimentation processes in the river and its estuary. Throughout this summer, experts from various Helmholtz Centres used a multi-system approach to investigate how the concentration and composition of the environmental chemicals, nano- and microplastic particles, nutrients and climate gases found in the river change on their way to the North Sea.
