Short summary

Monthly measurements of dissolved methane (CH₄), a potent greenhouse gas, were conducted at Boknis Eck (BE), a time-series station in the southwestern Baltic Sea, from June 2006. In general CH₄ concentrations increased with depth. High concentrations in the upper layer were linked to saline water inflow. Eckernförde Bay emitted CH₄ to the atmosphere throughout the monitoring period. No significant trend was detected in CH₄ concentrations or emissions during 2006–2017.
