Acknowledgments

This research used samples and data provided by the International Ocean Discovery Program (IODP). We are grateful to the IODP Technical Support staff and the R/V JOIDES Resolution crew for their invaluable help and dedication during what was a relentless and unremitting expedition. The perseverance and determination of the Technical Support staff were unparalleled.

The success of the expedition was also enabled by the support of the IODP Environmental Protection and Safety Panel (EPSP) and the Secretariat of Foreign Affairs (Secretaría de Relaciones Exteriores) of Mexico. The support from the National Autonomous University of Mexico (Universidad Nacional Autónoma de México [UNAM]) during the precruise clearance and visa approval processes is deeply appreciated. Support for development of the expedition objectives was provided by the Center for Dark Energy Biosphere Investigations (C-DEBI) (Catalina Island, California, USA) and the IODP U.S. Science Support Program (USSSP) (Puerto Vallarta, Mexico). The scientific groundwork that led to the conception of this expedition was supported by National Science Foundation (NSF) grants to Lizarralde (OCE011983, OCE0324983, and OCE0751901) and Teske (OCE1449604 and OCE1357239). The initial piston coring site survey was realized by Carlos Mortera (UNAM) and the crew of the R/V El Puma. The Ringvent survey critically depended on the HOV Alvin and AUV Sentry dives performed by the respective teams aboard the R/V Atlantis. Additional site survey data were acquired during R/V Sonne Cruise SO241 by Christian Berndt and other scientists from the Helmholtz Centre for Ocean Research Kiel as well as by Antonio Gonzalez (Centro de Investigación Científica y de Educación Superior de Ensenada [CICESE]) with funding from CICESE and IODP USSSP, and we are very grateful to those scientists and funding agencies.

The editorial staff at the IODP JOIDES Resolution Science Operator at Texas A&M University is thanked for their help with the publication of this document.


Foreword

The International Ocean Discovery Program (IODP) represents the latest incarnation of almost five decades of scientific ocean drilling excellence and is generally accepted as the most successful international collaboration in the history of the Earth sciences. IODP builds seamlessly on the accomplishments of previous phases: the Deep Sea Drilling Project, Ocean Drilling Program, and Integrated Ocean Drilling Program. The 2013–2023 IODP Science Plan (Illuminating Earth’s Past, Present, and Future) defines four themes and thirteen challenges for this decade of scientific ocean drilling that are both of fundamental importance in understanding how the Earth works and of significant relevance to society as the Earth changes, at least in part in response to anthropogenic forcing. This phase of IODP represents an intense level of international collaboration in bringing diverse drilling platforms and strategies to increasing our understanding of climate and ocean change, the deep biosphere and evolution of ecosystems, connections between Earth’s deep processes and surface manifestations, and geologically induced hazards on human timeframes.

The Proceedings of the International Ocean Discovery Program presents the scientific and engineering results of IODP drilling projects, expedition by expedition. As in the preceding Integrated Ocean Drilling Program, expeditions in the current IODP phase are conducted by three implementing organizations, each providing a different drilling capability. These are the US Implementing Organization (USIO; through September 2014) and the JOIDES Resolution Science Operator (JRSO; as of October 2014), providing the leased commercial vessel JOIDES Resolution for riserless drilling operations; JAMSTEC’s Institute for Marine-Earth Exploration and Engineering (MarE3), 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, for example, in polar environments and in shallow waters. Scheduling decisions for each capability are made 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 current 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 current IODP differs from prior scientific ocean drilling programs in that it has neither a central management organization nor commingled funding for program-wide activities. Yet this phase of IODP retains a fundamental integrative structural element: a “bottom-up” 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; all submitted proposals are then evaluated by a Science Evaluation Panel in the context of the Science Plan.

The current IODP also has a second internationally integrative level for high-level discussion and consensus-building: the IODP Forum. The Forum is not only charged with assessing program-wide progress toward achieving the current Science Plan, but also with overseeing approaches toward a new bright future of scientific ocean drilling post 2023. At present, IODP involves 25 international financial partners, including the United States, Japan, an Australia/New Zealand consortium (ANZIC), China, India, South Korea, and the eighteen members of ECORD (Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Israel, Italy, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, and the United Kingdom). This enhanced membership in the current IODP represents a remarkable level of international collaboration that remains one of the greatest ongoing strengths of scientific ocean drilling.
