Data Access Policy

Integrated Ocean Drilling Program Sample, Data, and Obligations Policy outlines the policy for distributing Integrated Ocean Drilling Program (IODP), Ocean Drilling Program (ODP), and Deep Sea Drilling Project (DSDP) samples and data. The moratorium period is one year long and begins either (1) after the conclusion of an expedition cruise if the majority of the sampling occurred during the cruise or (2) after the conclusion of the expedition onshore sampling party (onshore science party in case of the mission-specific platform). During the moratorium period, the only researchers permitted to receive expedition core materials and data are members of the Science Party. Expedition data are available online after the moratorium period.
