AWI Core Repository and Laboratory
The marine geology department curates and archives sediment cores from both polar oceans stored in the AWI Core Repository. The collection comprises more than 3600 gravity, piston and box cores sampled by Polarstern since 1983 with a total length of 12 km. Additional 4 km of cores from other research vessels supplement this polar sediment collection (Heincke, Sonne, Meteor, Marion Dufresne, Boris Petrov, Ivan Kireyev).
Lacustrine sediments cored from lakes in the Arctic and Antarctic are an additional part of the repository and provide the basic sampling material for the Periglacial Research Section of AWI Potsdam. Also the working half of the Cape Roberts Project cores are maintained by the AWI repository.
Cores are stored at 4°C and an air humidity limited at 35 % in sealed D-tubes.
The repository is completed by extensive laboratory facilities with 14 m sampling bench, digital fotographic and x-ray documentation, XRF-core scanner (Avaatech/NIOZ), sieving equipment, drying ovens, freeze dryers, centrifuge, grain size separation by sieving and Atterberg method, and grain size distribution measurements.
The repository is open to the scientific community for sampling subject to ongoing work at AWI. In principle cores must be sampled by the principle investigator. The repository does not provide any surface samples.
The AWI Core Repository is operated in close cooperation with the Bremen Core Repository (BCR)
