Cover photograph shows (left) false color image of Brothers volcano using high-resolution (~2 m) autonomous underwater vehicle–derived (~25 m) bathymetry overlain on surface ship–derived bathymetry. View is to the northwest with Upper Cone and flank Lower Cone in the foreground and NW Caldera walls and caldera rim in the background. Image created in Fledermaus by S.G. Merle (National Oceanic and Atmospheric Administration/Pacific Marine Environmental Laboratory). Right: drill string recovered from Hole U1528D. Very acidic, corrosive fluids with high concentrations of H2S contributed to the corrosion/embrittlement of the pipe (length of crack = 1.4 m), ultimately leading to failure and loss of the bottom-hole assembly.

Acknowledgments
This research used samples and data provided by the International Ocean Discovery Program (IODP). We sincerely thank the IODP Technical Support staff and the R/V JOIDES Resolution crew for their invaluable support, dedication, and perseverance during what was a challenging expedition. Their proficiency and determination were outstanding. We greatly appreciate the skill and tremendous efforts of the entire drilling crew to recover complex rock material within a technically demanding subseafloor environment. The qualified guidance of both Operations Superintendent Stephen Midgley (IODP JOIDES Resolution Science Operator [JRSO]) and Drilling Supervisor Sam McLelland (Siem Offshore) was crucial. The expedition’s success was also supported by the IODP Environmental Protection and Safety Panel and by the Ministry of Foreign Affairs and Trade and the Environmental Protection Authority of New Zealand, who approved a change in our drilling targets during the expedition with limited notice. Support from GNS Science (Te Pū Ao) during the pre-expedition clearance process is gratefully acknowledged. We appreciate the collaboration with MB Century/Century Drilling & Energy Services (NZ) Limited (New Zealand) and Petrospec Engineering Ltd. (Canada) and thank them for providing time, guidance, and expertise and making their downhole tools available to us. Their support significantly contributed to the success of the expedition. We thank JRSO Publications Services at the IODP JRSO at Texas A&M University for their help with the publication of this volume.
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 a renewed 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 new IODP 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 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, 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 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 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 new IODP also has a second internationally integrative level for high-level discussion and consensus-building: the IODP Forum. The Forum is charged with assessing program-wide progress toward achieving the Science Plan. At present, IODP involves 26 international financial partners, including the United States, Japan, an Australia/New Zealand consortium (ANZIC), Brazil, 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 new IODP represents a remarkable level of international collaboration that remains one of the greatest ongoing strengths of scientific ocean drilling.
