Formerly-glaciated areas are often characterized by deeply incised structures, often filled by Quaternary deposits. These buried troughs and valleys were formed by glacial overdeepening, likely caused by pressurized subglacial meltwater below warm-based glaciers. The overarching goal will be to date the age and extent of past glaciations. Results of this drilling campaign, supported by new dating technologies, will further provide critical data on 'how' and 'at which rate' glacial erosion affects such mountain ranges and their foreland. These processes are also of fundamental importance for evaluating the safety of radioactive waste disposal sites, which are planned in areas of former glaciations.

Vertical seismic profile measuring is currently taking place. The measurement comprises several settings around the two existing boreholes
Current depth in Basadingen is 171.5 m. Coring continues in mostly sandy glacilacustrine sediments with interbedded diamicts.
With 253 m we have reached the final depth in Basadingen-Schlattingen (site 5068-2)! We are very happy with the outstanding core quality and recovery; this is an excellent basis for the upcoming science part! The equipment is now prepared for the borehole logging by LIAG in the upcoming days.
We have arrived at a sequence of diamicts at a depth of 143 meters that likely represents the bottom of the overdeepened basin. The sediments are compact and therefore we have little losses.
