doi:10.2204/iodp.sp.327.2010 Sampling and data sharing strategyShipboard and shore-based researchers should refer to the IODP Sample, Data, and Obligations policy posted on the Web at www.iodp.org/program-policies/. 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 the co-chief scientists, 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 sample requests (at smcs.iodp.org/) 3 months before the beginning of the expedition. Based on sample requests (shore based and shipboard) submitted by this deadline, the SAC will prepare a tentative sampling plan, which will be revised on the ship as dictated by recovery and cruise objectives. The sampling plan will be subject to modification depending upon the actual material recovered and collaborations that may evolve between scientists during the expedition. Modification of the strategy during the expedition must be approved by the co-chief scientists, staff scientist, and curatorial representative on board ship. The minimum permanent archive will be the standard archive half of each core; whole-round samples are exempt from this rule. On this expedition, we anticipate substantial whole-round core sampling for hydrologic, geochemical, and microbiological investigations. Sampling may be particularly intense near the sediment/basement interface at one or more sites and within particular intervals in basement. Approximately 200 m of basement coring is planned at Sites SR-2 and 1027 (primary sites), and sediment coring will take place at the secondary sites only if time permits, providing as much as several hundred meters of material. All sample frequencies and sizes must be justified on a scientific basis and will depend on core recovery, the full spectrum of other requests, and cruise objectives. Some redundancy of measurement may be unavoidable, but minimizing the duplication of measurements among the shipboard scientific party and identified shore-based collaborators will be a factor in evaluating sample requests. | |
