doi:10.14379/iodp.sp.360.2015 Sampling and data sharing strategyShipboard and shore-based scientists participating in the Expedition 360 project should refer to the IODP Sample, Data, and Obligations Policy and Implementation Guidelines posted on the Web at www.iodp.org/program-documents/. 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, EPM/Staff Scientist, and IODP Curator (on shore) and curatorial representative (on board 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 research proposals and associated sample requests (web.iodp.tamu.edu/sdrm/) ~3–6 months before the beginning of the expedition (exact timeline to be announced by the EPM/Staff Scientist). Based on the shore-based and shipboard sample requests submitted by this deadline, the SAC will prepare a tentative expedition sampling plan, which will be subject to modification depending upon the actual material recovered and collaborations that may evolve between scientists during the expedition. Modification of the sampling strategy during the expedition must be approved by the SAC. The archive section half will not be sampled, except for a limited number of whole rounds if these are required to meet primary project objectives. Shipboard samples will be taken from the working section half, sparing the equivalent of one half of the section half (a quarter round) in all intervals if possible. All sample frequencies and sizes must be justified on a scientific basis and approval will depend to some degree on core recovery, the full spectrum of other requests, and the cruise objectives. Some redundancy of measurement is unavoidable or even desirable, but minimizing the duplication of measurements among the shipboard party and identified shore-based collaborators will be a factor in evaluating sample requests. If critical intervals with particularly high sampling demand are recovered, special decisions may be required, including reduced sample size, collaborations and sharing of samples and/or measurements results. A sampling plan coordinated by the SAC is typically required before critical intervals are sampled. The actual sampling of critical intervals may be postponed and carried out in the shore repository after the cruise. |
