Foreword 

By Integrated Ocean Drilling Program Management International, Inc.

The Integrated Ocean Drilling Program (IODP) is the most ambitious ocean exploration and drilling program 

ever undertaken. With multiple platforms and multiple partners, our research spans the globe and truly 

represents international collaboration and diplomacy among scientists and nations interested in attaining 

scientific goals. 

The Proceedings present the scientific and engineering results of IODP drilling projects, each an important 

component of an international program designed to better understand Earth, its environmental changes and 

processes, the deep biosphere, and climate change. 

The collective effort required to conduct each IODP expedition is colossal. Beginning with scientists who 

submit ocean drilling research proposals, there are others who evaluate, rank, and prioritize proposals. 

Scientists also schedule the science operations, select science party members from scores of international 

scientists qualified to participate, plan platform operations, ready the drillship, and choose borehole 

locations. There are onboard logistics to manage and critical communications to coordinate among various 

academic institutions, governments, and national science organizations. And the resulting data must be 

managed and made accessible to scientists, particularly those who will prepare future proposals. Every aspect 

of planning an IODP expedition takes a village—or several. There are many participants and many more 

stakeholders.

Ocean-drilling achievements, however complex, help us understand extraordinary linkages and interpret 

relationships as they exist in various parts of the Earth system. Achievements in two legacy drilling programs 

(the Ocean Drilling Program and Deep Sea Drilling Project) have validated the scientific concepts behind 

plate tectonics, contributed to the understanding of ocean circulation changes, and extended our knowledge 

of long- and short-term climate change—scientific information at the foundation of our current drilling 

program.

IODP drilling platform operations are conducted by three Implementing Organizations (IOs). Riserless 

platform operations are conducted by the JOI Alliance, comprising the Joint Oceanographic Institutions, Inc., 

Texas A&M University through the Texas A&M Research Foundation, and Lamont-Doherty Earth Observatory 

of Columbia University. Riser platform operations are conducted by the Japan Agency for Marine-Earth 

Science and Technology through Japan’s Center for Deep Earth Exploration in cooperation with the Center 

for Advanced Marine Core Research at Kochi University. Mission-specific platform operations are conducted 

by the European Consortium for Ocean Research Drilling, Science Operator, comprising the British Geological 

Survey, Bremen University, and the European Petrophysics Consortium. The European IO currently represents 

the ocean-drilling efforts of 16 nations in Europe, plus Canada. At the start of this drilling project, IODP 

involved 20 nations. 

The discoveries discovered in this volume build upon layers of knowledge and science developed over roughly 

the last fifty years. Expedition Proceedings are published by IODP Management International for IODP under 

the sponsorship of the U.S. National Science Foundation (NSF), Japan’s Ministry of Culture, Education, Sports, 

Science and Technology, and other IODP members. The material is based upon research supported under 

Contract OCE-0432224 from NSF.

Acknowledgments

We are grateful to the many individuals and organizations whose determination, skill, and creativity were 

essential to planning, preparing, and completing IODP Expedition 301. We begin by acknowledging the 

hundreds of scientists, administrators, and support staff who labored many years to bring about the first 

phase of IODP. We are particularly grateful for the efforts of representatives from the lead agencies and 

members to IODP who guided the development of planning documents, organized review and oversight 

panels, and forged the complex international agreements that make IODP possible. The scientific drilling 

community was pleasantly surprised to begin IODP at-sea operations ahead of schedule, and the Expedition 

301 Scientists were humbled to have been selected to participate in this first expedition of the new program.

Planning for Expedition 301 included numerous site surveys and proposal rewrites, along with spirited 

discussions over several years among proponents and others with interests in the hydrogeology of oceanic 

crust. Once the Expedition 301 experimental program was placed on the drilling schedule, we had only about 

9 months to design, build, and ship numerous engineering and scientific systems before the start of the 

expedition in June 2004. The efforts extended by USIO administrative, engineering, operations, technical, and 

scientific staff during this preparation period were extraordinary. The operational plan for achieving highpriority objectives during Expedition 301 was revised (and greatly improved) during several meetings among 

proponents and USIO staff members, and program funding was found to cover the costs of numerous CORK 

system components. We would particularly like to acknowledge the efforts of Operations Superintendent 

Mike Storms, and Engineers Derryl Schroeder, Tom Pettigrew, and Richard Dixon during this time. The JOIDES 

Resolution had been demobilized before Expedition 301, and the vessel had to be transited across the Pacific 

Ocean and numerous laboratory and engineering systems had to be installed (or reinstalled) and prepared for 

scientific operations in a short time. 

We benefited enormously during Expedition 301 from the hard work, ingenuity, experience, and good humor 

of the multitalented Transocean personnel, including Core Technicians Joe (Bubba) Attryde and Phil Christie, 

Operations Manager Wayne Malone, Tool Pusher Jose (Pepe) Estevez, and Drillers Nick Parrish and Charlie 

Watts. Their heroic efforts, and those of the USIO engineering, operations, and technical staff, were essential 

for successful assembly and deployment of complex observatory systems, particularly for salvaging and 

rebuilding the CORK system deployed in Hole 1301B. Several helicopter deliveries of critical parts and 

supplies were arranged on short notice, and we sincerely thank USIO, Science Services, TAMU, Deputy 

Director Jack Baldauf for supporting our efforts by approving these deliveries and otherwise working with us 

to resolve numerous unexpected difficulties before and during the expedition. All of the shipboard technical 

staff provided outstanding support for scientific activities throughout the expedition, but we would 

particularly like to highlight the contributions made by Yeoperson Michiko Hitchcox and Curatorial Specialist 

Paula Weiss. We also thank the officers and crew of the JOIDES Resolution for their service.

None of us who were involved in Expedition 301 could have imagined in advance how challenging or 

rewarding the experience would turn out to be. It was an amazing voyage.
