Special Data Types
Site Survey Data
Following the end of the IODP program, the IODP SSDB closed operations in 2025. A new SSDB supporting the US Scientific Ocean Drilling program is in development.The IODP SSDB no longer serves as a public data access point. Site Survey Data related to a subset of the IODP expeditions, when available, are now accessible from Zenodo(opens in a new tab) and are linked from the IODP Publications page.
