Gulf Coast Core Repository
About the GCR
The Integrated Ocean Drilling Program's (IODP) Gulf Coast Repository (GCR) is located in the Research Park on the Texas A&M University campus in College Station, Texas. This repository stores DSDP, ODP, and IODP cores from the Pacific Ocean, the Caribbean Sea and Gulf of Mexico, and the Southern Ocean. A satellite repository at Rutgers University houses New Jersey/Delaware land cores 150X and 174AX.
The GCR houses over 100 kilometers of cores that are kept refrigerated at 4°C. In addition, the GCR stores thin section, smear slide, and residue collections, which are available to the scientific community for scientific study.
Another function of the GCR is to host tours and to promote the educational use of the cores. The repository maintains close links with Texas A&M University and hosts a historical geology course each year.
Obtaining Samples
One of the main functions of the GCR is to provide a service to the international scientific community. Scientists engaged in geoscience research are welcome to schedule a visit to the GCR to study or sample core, or to request samples to be taken and shipped by GCR staff. Visitors have at their disposal three computerized sampling stations, digital and conventional photo equipment, and a microscope lab.
Scientists may obtain samples by submitting a sample request form. Please familiarize yourself with the IODP sample and data obligations policy before requesting samples.
Please contact us before you make travel arrangements to ensure that the GCR is available and prepared for your visit:
