Selected Research Projects Marine Geochemistry

PACES: Our participation in the Programme "Polar regions and Coasts in a changing Earth System"

MARUM: DFG Research Center/Cluster of Excellence „The Ocean in the Earth System“

MARUM aims at understanding the role of the oceans in the Earth’s system by employing state-of-the-art methods. It examines the significance of the oceans within the framework of global change, quantifies interactions between the marine geosphere and biosphere, and provides information for sustainable use of the ocean.

We contribute to the study of the cycling of natural radionuclides

Contact: Michiel Rutgers van der Loeff

KnowSeas: Knowledge-based Sustainable Management for Europe's Seas

Jana Friedrich contributes to WP3 “Causes and consequences of ecosystem change” and to WP8 “Black Sea regional study”.

Funding agency: European Commission under the Environment (including climate change) Theme of the 7th Framework Programme for Research and Technological Development

Contact: Jana Friedrich, Justus van Beusekom

IMCOAST

International research programme on the impact of climate induced glacial melting on marine coastal systems at King George Island (Western Antarctic Peninsula). Collaborating ESF partner institutions in Belgium, Germany, The Netherlands, Poland, Spain and associated projects in Argentina, Brazil and the UK.

HYPOX: In situ monitoring of oxygen depletion in hypoxic ecosystems of coastal and open seas, and land-locked water bodies

Jana Friedrich is leader of WP3 “Existing and future impacts of hypoxia on ecosystems” and contributes to WP6 ”Assessing in situ oxygen depletion in shelf and open seas”

Funding agency: European commission under Cross-cutting research activities relevant to GEO and Environment Theme of the 7th Framework Programme for Research and Technological Development

Contact: Jana Friedrich, Thomas Soltwedel

BALTIC GAS is a research project exploring emissions of the greenhouse gas methane from the seabed of the Baltic Sea into the overlying water column and further into the atmosphere.

Funding Agency: BALTIC GAS is funded by BONUS The Baltic Organisations Network for funding Science EEIG.

Contact: Michael Schlüter

COSYNA: Coastal Observing System for Northern and Arctic Seas

We contribute to the design, testing and application of NUSOBS, a Nutrient and Suspension Observatory, to be deployed in the German Bight.

Funding Agency: Funded via Helmholtz Association grant to the HZ-Geesthacht

Contact: Jana Friedrich, Michael Schlüter, Till Oehler

EUROPROX: International Graduate College “Proxies in Earth History”

This program focusses on the development, testing and improvement of “proxy parameters” and “proxy methods” in marine research to allow the accurate reconstruction of paleoceanographic, paleoclimatic and paleoenvironmental conditions from marine archives.

Funding agency: German Science Foundation (DFG)

Contact: Sabine Kasten, Susann Henkel

SO-205 MANGAN: Geochemie und Biogeochemie. SO 205

The project SO 205 – MANGAN investigates the microbiology, biogeochemistry, paleoceanography and biodiversity in the Manganese Nodule Belt of the Equatorial NE Pacific

Funding Agency: BMBF

Contact: Sabine Kasten, Konstantin Mewes

INOPEX: Innovative North Pacific Experiment

Within the framework of INOPEX we investigate the impact of diagenetic and biogeochemical processes on paleoceanographic proxies and rock magnetic properties

Funding agency: BMBF

Contact: Rainer Gersonde, Sabine Kasten

Finished projects

DAMOCLES: (Developing Arctic Modeling and Observing Capabilities for Long-term Environmental Studies) was an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic. DAMOCLES was specifically concerned with the potential for a significantly reduced sea ice cover, and the impacts this might have on the environment and on human activities, both regionally and globally.

We studied the distribution of Barium, Thorium and Radium isotopes in the Arctic
