  • The service of sediments in German coastal seas – evaluating the function of marine benthic systems in the context of human use – Service functions of the Baltic Sea- (SECOS): WP 2.4 "Gas exchange at the sediment water interface"

[For Details click here!]

Coastal and marginal seas operate as natural reaction sites for the processing and accumulation of land-derived discharges, e.g. nutrients, toxic substances, biotic/abiotic material. The main locations of accumulation as well as chemical/biological modification are almost the sediments. Surprisingly, their key position in the complex land-sea interaction is insufficiently studied and assessed so far. Within the framework of the BMBF-project SECOS („The service of sediments in German coastal seas“), the distribution and quantitative relevance of sedimentary services will be mapped and modelled in the range of the German Baltic Sea waters. Existing management tools for marine coastal systems will be improved, including human impacts and projections of future scenarios. This will be realised by the functional assessment of those sedimentary areas that are most relevant contributors to desired feedbacks to the environment and society. Thus, a first approach of a monetary “ecosystem service” assessment will be generated and all results will be presented in summarised habitat maps. Within the work package 2.4 “Gas exchange at the sediment- water interface”, fluxes of the greenhouse gases CH4, N2O and CO2 will be determined for key sediment types. This aims for a mechanistic understanding of the loss of CH4 and N2O from sediments as a first step towards implementation in the model framework. Therefore, modern analytic methods will be applied such as gas chromatography and mass spectrometry. The sampling will be performed at 20-30 m water depths with a benthic chamber lander system. A first ship cruise with “RV Alkor” is planned for March 2014.
