International core repository at the University of Bremen
BCR presently contains 154 km of deep-sea cores from 89 expeditions in around 250,000 boxes (also see reports), which are sampled and analysed by national and international working groups. Around 200 scientists visit the repository annually, sometimes working on the cores in week-long sampling meetings (video). As many as 50,000 samples per year are taken by guests and by the repository staff. The repository is an important contact point for scientists from all over the world (more than 2,000 visitors so far) and therefore significantly contributes to the exchange and transfer of marine science knowledge in Bremen, leading to international co-operations and scientific interactions.
Land-based cores from ODP Legs 150X and 174AX are stored at the Rutgers/New Jersey Geological Survey (RU/NJGS) core repository in Piscataway, NJ.
Requesting samples from deep-sea cores
To identify where samples have already been removed please search the Web Interface for BCR Curatorial Data (or here for samples taken (in all repositories) before the start of the IODP).
Samples can be taken by repository staff, or scientists can visit the repository to take their own samples. A variety of sampling tools and procedures are available.
Microbiology Sample Material Availability
One of the scientific goals of IODP is to research the deep biosphere and the subseafloor ocean. IODP has deep-frozen microbiological samples from the subseafloor available for interested researchers and will continue to collect and preserve geomicrobiology samples for future research. The list of available samples at BCR you will find here:
