Data Access

Data from IODP expeditions can be accessed via the expedition's Implementing Organization:  


The integrated data and publications portal from the Integrated Ocean Drilling Program 2003-2013 Scientific Earth Drilling Information System (SEDIS) is funded by ECORD and supported by MARUM. SEDIS allows search across source databases and aggregation of data sets through 2013 from:

  • Post-moratorium data and metadata from all IODP and legacy program data systems (e.g., JANUS, LIMS, J-CORES, WDC-MARE/PANGAEA, Logging Database SSDB, etc.)
  • Publications and publications metadata from IODP/ODP/DSDP and the open literature related to scientific ocean drilling
  • Post-expedition data and metadata from post-cruise data capture projects and voluntarily submitted post-expedition data sets 

Site Survey Data Bank

The Site Survey Data Bank (SSDB) is a repository for digital site survey data submitted in support of IODP proposals, expeditions and related activities. Many files are freely available, but proprietary holds requested by proponents are strictly maintained. The SSDB also contains older site survey data for some ODP proposals and legs. Analog site survey data (e.g., paper plots) submitted in support of IODP, ODP and DSDP proposals and expeditions/legs are stored on site at the SSDB.

Sample Access

Sample materials collected during IODP, ODP , and DSDP expeditions are available to researchers from any nation or research institution. Scientific merit is the primary criterion for consideration of sample materials requests.

Three repositories archive physical samples from IODP expeditions. Samples are distributed according to ODP and IODP policies.

IODP imposes a moratorium, generally one year from completion of the expedition, during which sample access is restricted to members of the expedition science party. For core intervals of exceptional scientific interest, collaboration amongst scientific teams is desired to promote the most comprehensive understanding of the materials obtainable through carefully planned analytical research.

The IODP Sample, Data, and Obligations Policy outlines the obligations that accompany approved sample requests. In particular, successful fulfillment of the publication obligations are an important criteria for approving subsequent sample requests. Sample materials may also be loaned for educational or outreach purposes. For more information on obtaining IODP/ODP/DSDP sample materials for non-research purposes, consult the Sample and Data Publication Policy.

A Curatorial Advisory Board makes final decisions regarding distribution of IODP samples.

Microbiology Sample Material Availability

One of the scientific goals of IODP is to research the deep biosphere and the subseafloor ocean. IODP has 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 microbiological samples available from Bremen Core Repository is located here. The microbiological sampling material available for request from the Kochi Core Center is accessible here. The list of available samples from the Gulf Coast Repository is available here
