Sampling and data-sharing strategy

Shipboard and shore-based researchers should refer to the IODP Sample, Data, and Obligations policy (www.iodp.org/program-policies/). This document outlines the policy for distributing IODP samples and data. It also defines the obligations incurred by sample and data recipients. All requests for data and core samples must be approved by the Sample Allocation Committee (SAC). The SAC is composed of Co-Chief Scientists, Staff Scientist, and IODP Curator on shore and curatorial representative in place of the Curator on board the ship.

Scientists must submit their research plans using the Sample/Data Request form (smcs.iodp.org/) no later than 3 months before the expedition. This planning process is necessary to coordinate the research to be conducted and to ensure that the scientific objectives are achieved. Based on the sample requests (shore based and shipboard), the SAC and Shipboard Scientific Party will formulate an expedition-specific sampling and data-sharing plan for shipboard and postexpedition activities. This plan will be subject to modification depending upon the actual material recovered and collaborations that may evolve between scientists during the expedition. Modifications to the sampling plan during the expedition require the approval of the SAC.

All sample frequencies and sizes must be justified scientifically and will depend on core recovery, the full spectrum of other sample requests, and the cruise objectives. Some redundancy of measurement 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 will be expected to collaborate and cooperate within the framework of this plan. Sampling for individual scientist's postcruise research may be conducted during the expedition or may be deferred to postcruise.

If critical intervals are recovered (e.g., prominent unconformities, ash layers), there may be considerable demand for samples from a limited amount of cored material. These intervals may require modifications to the sampling plan (e.g., special handling, reduced sample size, or deferring of sampling to postcruise).

Following Expedition 317, cores will be delivered to the IODP Core Repository at Texas A&M University, College Station, USA. All collected data and samples will be protected by a 1 year postcruise moratorium, during which time data and samples are available only to the Expedition 317 science party and approved shore-based participants. This moratorium will extend either 1 year from the end of the expedition, or, if a postcruise sampling party is required, 1 year following the completion of the sampling party.
