Abstract
Lake Geneva is a large, holomictic, eutrophic lake with a maximum depth of about 300 m. The sediments in the central basin have a pillow-like appearance. The soft elevations containing the major portion of the recently sedimented detritus are separated by trenches of 5 to 15 cm depth in which the top sediment layers seem to be missing. Bottom-dwelling fishes (Lota lota) prefer the trenches as their habitat and might partly be responsible for the turbation of the trench sediment layers. Thus, within distances of 10 to 30 cm two sediment types can clearly be distinguished. They differ with respect to morphology and chemical stratification
