In combination with a 14C- and OSL-based age-depth model, the core was divided into three main chronostratigraphic units.

14 lithotypes were identified through petrophysical and geochemical analyses. The sediments recovered consist of a nearly continuous succession of lacustrine silts and sands including more than 12 m of Late Glacial sediment at the base.

During the successful field test of a newly developed, mid-size coring system ('HIPERCORIG'), the longest core (HIBO19) ever taken in Lake Constance was retrieved with an overall length of 24 m. The stratified sedimentary fill consists at the base of ice-contact deposits on top of the molasse bedrock, overlain by glaciolacustrine to lacustrine sediments. A seismic survey of Lake Constance revealed a Quaternary sediment fill of more than 150 m thickness representing at least the last glacial cycle. The overdeepening was formed by repeated glacial advance-retreat cycles of the Rhine Glacier throughout the Middle to Late Pleistocene. The modern, over 250-m-deep basin of Lake Constance represents the underfilled northern part of an over 400-m-deep, glacially overdeepened trough, which reaches well into the Alps at its southern end.
