The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were to refine budgets and operational plans for Phase 2 of this cooperative agreement based on the scheduling of a scientific ocean drilling expedition to study marine methane hydrates along the Cascadia margin, in the NE Pacific as part of the Integrated Ocean Drilling Program (IODP) using the R/V JOIDES Resolution. The proposed statement of work for Phase 2 will include three primary tasks: (1) research management oversight, provided by JOI; (2) mobilization, deployment and demobilization of pressure coring and core logging systems, through a subcontract with Geotek Ltd., who will work with Fugro and Lawrence Berkeley National Laboratory to accomplish some of the subtasks; and, (3) mobilization, deployment and demobilization of a refrigerated container van that will be used for degassing of the Pressure Core Sampler and density logging of these pressure cores, through a subcontract with the Texas A&M Research Foundation (TAMRF). More details about these tasks are provided in the following sections of this report. The appendices to this report contain a copy of the scientific prospectus for the upcoming IODP Expedition 311 (Cascadia Margin Hydrates), which provides details of operational and scientific planning for this expedition.
