Clusters of Excellence 80 (EXC): The Future Ocean, Sea Floor Warming - Novel, non-invasive investigation of seafloor warming on oxygen and heat fluxes from the benthic boundary layer into the water column

Description: The existing O2 Eddy Correlation (EC) systems will be modified to log in a fully non-invasive way, besides dissolved oxygen (DO) and velocity, also rapid temperature fluctuations. The coupling of heat flux and DO flux will be used to determine if, and to which extend, DO fluctuations are indeed due to active turbulence or to non-active (fossil) signals. We will gain knowledge of temperature dependencies of DO fluxes and we expect to be able to express the DO fluxes as a function of the heat fluxes and predict DO fluxes for varying benthic temperatures. By integrating also water column microstructure profiler data we will obtain important information on the oxygen dynamics.
