Acknowledgments

This research used samples and data provided by the International Ocean Discovery Program (IODP). We thank all of the personnel aboard the R/V JOIDES Resolution during Expedition 352 for their skill and dedication. Particular thanks go to the Technical Support staff for the quality and timeliness of their work. Stephen Midgley deserves special recognition for his recommendation to drill in casing, which allowed the final two holes to be drilled. The editorial staff at the IODP JOIDES Resolution Science Operator in TAMU are thanked for help with publication of this document. Suichi Kodaira, Mikaya Yamashita, and Daniel Lizarralde are thanked for site surveys and help interpreting and uploading the survey data. We gratefully acknowledge Bob Stern for his key role in the initial formulation and development of the proposal. We also thank Osamu Ishizuka and the other drilling proposal proponents, as well as the members of the Science Evaluation Panel (Chair: Dick Kroon) for making Expedition 352 possible.


Foreword

The International Ocean Discovery Program (IODP) represents a renewal and strategic refocusing of what has been widely hailed as one of the most successful and ambitious international scientific programs in the world. Based solidly on the 45-year scientific legacy of the Deep Sea Drilling Project, Ocean Drilling Program, and Integrated Ocean Drilling Program, the new IODP Science Plan (Illuminating Earth’s Past, Present, and Future) defines 4 main themes and 13 challenges for the next decade of scientific ocean drilling that are both of fundamental importance in understanding how Earth works and of high relevance to society as Earth changes. The new IODP represents an extraordinary level of international collaboration in utilizing scientific ocean drilling to understand climate and ocean change, the deep biosphere and evolution of ecosystems, connections between Earth’s deep processes and surface impacts, and geological processes and hazards on human scales.

The Proceedings of the International Ocean Discovery Program presents the scientific and engineering results of IODP drilling projects on an expedition basis. As in the preceding Integrated Ocean Drilling Program, expeditions in the new IODP will be conducted by three implementing organizations, each providing a different drilling platform. These are the U.S. Implementing Organization (USIO; through September 2014) and the JOIDES Resolution Science Operator (JRSO; as of October 2014), providing the research vessel JOIDES Resolution for riserless drilling operations; JAMSTEC’s Center for Deep Earth Exploration (CDEX), providing the drillship Chikyu for riser and occasional riserless operations; and the European Consortium for Ocean Research Drilling (ECORD) Science Operator (ESO), providing mission-specific platforms (MSPs) for expeditions that extend the IODP operational range where neither drillship is suitable. Scheduling decisions for each of the platforms are made separately by three independent Facility Boards, each of which includes scientists, operators, and platform funding partners: the JOIDES Resolution Facility Board (JRFB), Chikyu IODP Board (CIB), and ECORD Facility Board (EFB). At the beginning of the new IODP, the three Facility Boards agreed to utilize Publication Services at the USIO and now the JRSO for production of all expedition Proceedings volumes and reports.

The new IODP differs from prior legacy programs in that it has no central management authority nor commingled funding for program-wide activities. Yet the new IODP retains a key integrative structural element: evaluation of all proposals for drilling expeditions by a single advisory structure composed of scientists representing all international program partners. International scientists may submit drilling proposals to the Science Support Office; the proposals are then evaluated by the Science Evaluation Panel in the context of the new Science Plan.

The new IODP also has a second internationally integrative level for high-level discussion (but no executive authority): the IODP Forum. The Forum is defined as the custodian of the Science Plan and is charged with assessing program-wide progress toward achieving the Science Plan. As of the Forum’s first annual meeting (May 2014), IODP involves 27 international financial partners, including the United States, Japan, an Australia/New Zealand consortium (ANZIC), Brazil, China, India, South Korea, and the 19 members of ECORD (Austria, Belgium, Canada, Denmark, Finland, France, Germany, Iceland, Ireland, Israel, Italy, Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, and the United Kingdom). The enhanced membership in the new IODP represents a remarkable level of international collaboration that remains one of the greatest strengths of scientific ocean drilling.
