Bioturbation effects on coastal Ocean Acidification
Due to elevated emissions of carbon dioxide (CO2) into the atmosphere, oceanic uptake of CO2 is increasing and the oceanic carbonate system altered in a phenomenon termed Ocean Acidification (OA). As the oceanic pH has steadily decreased in near-perfect conjunction with increasing atmospheric CO2 levels (Left figure), the oceanic uptake of CO2 will decrease as a consequence of alterations in the seawater carbonate system. How come that in relatively shallow shelf systems like the North Sea, the trend in pH decrease of the open ocean is not followed? Which geochemical processes contribute to this discrepancy?Read more … Bioturbation effects on coastal Ocean Acidification

Electricity-generating bacteria in the seafloor: optical characterization of extracellular polymeric sheaths
Very recently, long filamentous bacteria have been discovered in marine sediments that are able to generate electrical currents and mediate the transport of electrons across centimeter-scale distances. These electrogenic bacteria let the ocean floor operate like a natural battery, and have an enormous potential for various bio-electric applications. In this project, we will study these sheaths using a novel technique – digital holographic microscopy (DHM). The research activities will consist of field sampling (Dutch delta area), the cultivation of marine organisms (filamentous bacteria), sample preparation, microscopic imaging, and the processing and analysis of images.
Food web studies of the cold-water coral reef community have shown that these are among the most productive benthic ecosystems in the deep sea and hence a comparatively large amount of secondary production is potentially available as food for higher trophic levels such as fish. Models of the food web structure of cold-water coral communities at various sites in the northeast Atlantic have been developed in our lab using food web modeling. These models will be extended with fish compartments to quantify the predation pressure of fish on the reef community.Contact
