doi:10.2204/iodp.sp.337add.2011 Changes to the drilling and coring planThe Hybrid–Pressure Core Sampler (PCS) will not be used to retrieve methane hydrate–bearing sediments from shallow sedimentary sections under in situ pressure conditions. Planned coring at Site C9001 with the hybrid-PCS will not be conducted, and formation temperatures will not be taken at that site with the Advanced Piston Corer Temperature Tool (APCT-3). A revised operations schedule is shown in Table T2. Changes to the analytical planPaleomagnetic measurements will not be conducted on board the Chikyu during Expedition 337. In addition, P-wave velocity, gamma density, and X-ray CT scans will not be conducted on high-pressure cores, and in situ chemical composition and concentrations of free hydrocarbon gas will not be conducted using the Pressure Core Analysis and Transfer System (PCATS). |
