Data sets

Sediment and water column parameters measured at Boknis Eck (SW Baltic Sea) on a seasonal basis from 2013-2014 J. Maltby, L. Steinle, C. R. Löscher, H. W. Bange, M. A. Fischer, M. Schmidt, and T. Treude https://doi.org/10.1594/PANGAEA.873185

Short summary

The activity and environmental controls of methanogenesis (MG) within the sulfate-reducing zone (0–30 cm below the seafloor) were investigated in organic-rich sediments of the seasonally hypoxic Eckernförde Bay, SW Baltic Sea. MG activity was mostly linked to non-competitive substrates. The major controls identified were organic matter availability, C / N, temperature, and O₂ in the water column, revealing higher rates in warm, stratified, hypoxic seasons compared to colder, oxygenated seasons.
