Drilling Overdeepened Alpine Valleys

Project Acronym: DOVE | State: Operational Phase | Expedition ID: 5068

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.

Drilling the permeable Illmensee gravels which lacks a fine

Drilling the permeable Illmensee gravels, which lacks a fine matrix, proves difficult since it causes significant loss of the drilling fluid. In addition, we need to re-set the casing every couple of meters.
