National core repository for continental research drilling

For scientific drilling on land so far, there has not been any central facility for professional curation of samples and cores with data management and information portal yet.
For this reason, the German Scientific Earth Probing Consortium has supported the building of a national core repository for continental research drilling.

The MARUM Center for Marine Environmental Sciences at the University of Bremen and the Federal Institute for Geosciences and Natural Resources (BGR) in Hanover have jointly developed a concept to store both chilled drill cores e.g. lake sediments, as well as unchilled solid rock samples centrally and to make this material accessible permanently for scientific investigations.

Use of core repositories

The two repositories at the MARUM in Bremen and in Berlin (department of the BGR) are available to the scientific community. Valuable and well-documented samples can be included in the core repositories upon request.

The definition and adherence of the core repository statutes for qualitative standards as well as acceptance conditions of drill cores at both locations is ensured by a board of trustees. The data is archived using the Drilling Information System (DIS).

In addition to storage facilities and on-site expertise, both sites have facilities for core descriptions and professional, efficient sampling as well as state-of-the-art technology for non-destructive core analysis such as petrophysical and X-ray fluorescence scanners (multi-sensor core loggers, XRF scanners).

Core repository-board of trustees

A board of trustees acts in the background as an independent supervisory committee with advisory functions and decides on the inclusion of sample material. Requests for curation are welcome. Please contact the relevant core repository curators Ursula Röhl, responsible for the material to be chilled, as well as Tina Kollaske, contact person for sample material, which does not require cooling.

Core Repository Locations

Samples such as cores, cuttings, fluids are the primary targets of scientific drilling. High costs and great effort are needed to win them. Safe and well documented, the samples are available for a long time. Therefore, modern core repositories are an important element of research drilling.

          BGR, Berlin Spandau

Samples and cores from bedrock for a core length of up to 35 km can be stored in the core repository of the BGR site in Berlin Spandau since 2012.

In 2011, an agreement was signed between MARUM and GESEP also store lake sediment cores in Bremen Core Reposotory (BCR) at 4 ° C. At the moment mainly samples of the international drilling programs DSDP, ODP and IODP from the Atlantic are beeing stored at the BCR.
