The Site Survey Data Bank (SSDB) is a repository for digital site survey data submitted in support of Integrated Ocean Drilling Program (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, which is located at Scripps Institution of Oceanography (more information about analog documents can be found here).
