During PS85 (in 2014) and PS93.2 (in 2015) autonomous benthic lander were deployed at the HAUSGARTEN stations HG I and HG IV. The lander was equipment with a profiler unit, which holds electrochemical, needly type oxygen sensors in order to measure oxygen profiles across the sediment-water interface. By using the profiles, the diffusive oxygen uptake was calculated via the decrease in the oxygen concentration in the Diffusive Boundary Layer (DBL). For a further description of the calculation, please check the related publication.
