This site aims to distribute the science data acquired by International Ocean Discovery Program and Integrated Ocean Drilling Program expeditions of D/V CHIKYU. All the scientific data record in the database as well as data files are available for downloading from this site. More about the contents of this site…

ChangeLog should be referred to know how this site has been updated.

Data Access Policy

In International Ocean Discovery Program Sample, Data, and Obligations Policy & Implementation Guidelines: The goal of this policy is to ensure open and transparent access to International Ocean Discovery Program (IODP), Integrated Ocean Drilling Program (IODP), Ocean Drilling Program (ODP), and Deep Sea Drilling Project (DSDP) samples and data for scientists, educators, museums, and outreach institutions. IODP imposes a moratorium, one year from completion of the expedition, during which data access is restricted to members of the expedition science party. Project data are publicly available after the moratorium period.
