melting more and more frozen ground in the Arctic. This dissolved matter contains large amounts of organic carbon which is flowing into the central Arctic ocean. In a new study, scientists led by Alfred [...] matter accumulates in the central Arctic Ocean. Using chemical fingerprints, they were able to assess how fast it degrades, thus releasing additional CO2 to the ocean. These findings are an important basis [...] basis to project how inputs from land affect Arctic marine ecosystems and the ability of the ocean to store CO2 in a warming climate. The results are published in the journal Nature Geoscience.

We will continue expanding our measurements

Markus Rex led the MOSAiC-Expedition , the largest Arctic research expedition of our time, during which the research vessel “Polarstern” was frozen in the Arctic ice for a year to study the effects of climate [...] climate change. Scientists from 20 nations collected valuable data about the Arctic, which is crucial for understanding the future climate change. In the SR3 podcast “Aus dem Leben”, Markus Rex reports on his [...] findings of this unique mission. The data obtained provides important insights into the dynamics of the Arctic climate and its global impact. SR3 Podcast: Die größte Arktis-Mission aller Zeiten Christian Haas

The scarcely explored region to the north of Greenland was the area of study in the last of three Arctic expeditions undertaken by the Polarstern since the end of May 2025. In the largely untraveled waters [...] oceanographer Torsten Kanzow of the Alfred Wegener Institute were able to collect unique data on ocean circulation in the area. A chain of six moorings was also deployed to conduct autonomous measurements

The goal was to gain a better [...] better understanding of the complex interaction between the ocean, the ice, the atmosphere and the ecosystem. Through the MOSAiC expedition, hundreds of scientists representing institutions from across [...] significant contributions to the global understanding of climate feedback mechanisms in the central Arctic.
