This data set was collected from incubations of sediment collected from the intertidal sandbank Janssand, behind the back barrier island Spiekeroog, in the German Wadden Sea. The rate of oxygen consumption (microsensor), hydrogen accumulation (GC), iron accumulation (ferrozine, chlorometric), and sulfate reduction (35S sulfate + acid-chromium distillation) were all measured in constantly mixed slurries, with and without the ROS-removing enzymes superoxide dismutase and catalase. It additionally includes depth profiles of oxygen and hydrogen peroxide in cores, determined with amperometric microsensors.
