These will provide multidisciplinary observations in all parts of the oceans from the [...] Purser SenseOcean (Marine sensors for the 21st Century) EU funded FP7 project Duration: 01.10.2013 - 30.09.2017 Coordinator: Denise Martin, Natural Environment Research Council, UK SenseOCEAN brings together

Photosynthesis in near darkness

under the snow and ice cover of the Arctic Ocean. The results of the study now published in the journal Nature Communications show that photosynthesis in the ocean is possible under much lower light conditions [...] low light levels. This is the result of an international study that investigated the development of Arctic microalgae at the end of the polar night. The measurements were carried out as part of the MOSAiC

In this way researchers can analyse the climatic changes in the Arctic and their impact on the fauna in the future with higher temporal and spatial resolution.

Coastal carbon sinks protect permafrost material from decomposition

show, part of the biomass released becomes trapped in deep sinks on the ocean floor off the Arctic coast – where it is protected from microbial decomposition. The outcomes of their analyses are intended [...] Permafrost
The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once [...] Once eroded material is released into the ocean, microorganisms break down ancient plant remains, releasing sizable quantities of greenhouse gases. Yet, as the latest analyses conducted by AWI experts show
