Measurements of CH4 ebullition were conducted bi-weekly from May to October 2017 and April to November 2018. Sedimentation rates were measured in 2018 in four-week intervals. Characteristics of the sedimented material were measured in 2017 and 2018. Sediment characteristics were measured in November 2017, spring 2018 and August 2019. Meterological parameters (temperature and air pressure) were constantly measured from a floating platform in the lake center.
