Sampling and data sharing strategy

Shipboard and shore-based researchers should refer to the IODP Sample, Data, and Obligations policy at This document outlines the policy for distributing IODP samples and data to research scientists, curators, and educators. The document also defines the obligations that sample and data recipients incur. The Sample Allocation Committee (SAC) (composed of co-chief scientists, staff scientist, and IODP curator on shore and curatorial representative on board the ship) will work with the entire scientific party to formulate a formal expedition-specific sampling plan for shipboard and postcruise sampling.

Shipboard scientists are expected to submit postcruise research plans, including sample/data requests (at no later than 3 months before the beginning of the expedition. This timing is necessary to coordinate the research to be conducted and to ensure that the scientific objectives are achieved. Based on sample requests (shore-based and shipboard), the SAC will prepare a tentative sampling plan. The sampling plan will be subject to modification depending upon the actual core recovery and collaborations that develop between scientists during the expedition. The SAC must approve modifications of the sampling strategy during the expedition.

All personal sample frequencies and sizes must be justified on a scientific basis and will depend on core recovery, the full spectrum of other sample requests, and the cruise objectives. Some redundancy of measurements is unavoidable, but minimizing the duplication of measurements among the shipboard party and identified shore-based collaborators will be a factor in evaluating sample requests. All shipboard scientists and approved shore-based requesters are expected to collaborate and cooperate within the framework of this plan. Sampling for individual scientist’s postcruise research will completely depend on core recovery and may either take place on the ship or be deferred until after the cruise. This decision will be made during the expedition when core recovery and quality are better known.

Following Expedition 356, cores will be delivered to the IODP Core Repository at Kochi, Japan. All collected data and samples will be protected by a 1 y moratorium during which time they are available only to the Expedition 356 science party and approved shore-based participants. This moratorium will extend 1 y following either the end of the expedition or the completion of a postcruise sampling party, if required.
