<md:abstract>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.</md:abstract>
