<Summary>In the south-eastern part of Lake Constance a deep pockmark, a shallow pockmark station, as well as a reference station have been sampled for dissolved methane concentrations (with water samples) and hydrographic parameters with a Seabird CTD probe. The rosette was located within the pockmark with the help of a horizontal scanning sonar. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.965892"!</Summary>
