Continental scientific drilling allows to investigate the geological subsurface of the continents including its fluids and biosphere. As logistics and costs of such drilling campaigns are significant, the science communities of 24 nations joined during the last decades to form the International Continental Drilling Program (ICDP). Forces were merged to define highest-priority drilling goals through international collaborations. Switzerland joined the ICDP in 2008 as regular member, offering now the Swiss scientists the opportunity to propose, conduct and sample drilling operations anywhere on the continents.
