Abstract:

This dataset consists of sensor data from field experiments with time-series point measurements. These benthic MiniChamber experiments were run at five stations for 20 h during cruise EMB374 (04.09.2025 - 13.09.2025). An O2 optode with integrated temperature sensor (Aanderaa, Norway), as well as pH and sulfide micro sensor (Unisense, Denmark), were measuring within the benthic chamber during the 20 h experimental run. The data set will be used to highlight similarities and differences in the benthic system of the Kiel Bight. Oxygen respiration and sulfide flux rates from the benthic chamber can be extrapolated to larger areas of Kiel Bight, providing insights into more widespread occurrences of sulfide emissions.
