The expedition you are about to experience, as well as the majority of future ocean drilling in this region, are jointly funded by the Center for Deep Earth Exploration in Japan and the National Science Foundation in the U.S.

The National Science Foundation (NSF), an independent federal agency created by Congress in 1950, is the funding source for approximately 20 percent of all federally supported basic research conducted by America's colleges and universities. It is the only federal agency whose mission includes support for all fields of fundamental science and engineering, and is tasked with keeping the United States at the leading edge of discovery in areas from astronomy to geology to zoology. NSF operates from the "bottom up," keeping close track of research around the United States and the world, maintaining constant contact with the research community to identify ever-moving horizons of inquiry, monitoring which areas are most likely to result in spectacular progress and choosing the most promising people to conduct the research. And in every case, the research is fully integrated with education so that today's revolutionary work will also be training tomorrow's top scientists and engineers. (Modified from www.nsf.gov)

Within the NSF, the MARGINS program provides a community focal point for science that aims to understand the origin and evolution of the continents through investigation at their active margins, in four major initiatives. This is encapsulated in the MARGINS Program mission statement, “to understand the complex interplay of processes that govern continental margin evolution globally.” The connection between global processes and continental evolution lies at ocean-continent margins, the sites of most processes that modify continents, and encompasses what are perhaps some of the largest challenges in solid Earth science. In this expedition, you will join a research project conducted under the Seismogenic Zone Experiment initiative (SEIZE) of the NSF MARGINS program.

The Integrated Ocean Drilling Program is an international marine research program that explores Earth's history and structure recorded in seafloor sediments and rocks, and monitors subseafloor environments. IODP builds upon the earlier successes of the Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP), which revolutionized our view of Earth history and global processes through ocean basin exploration. IODP greatly expands the reach of these previous programs by using multiple drilling platforms to achieve its scientific goals of understanding the deep biosphere and the subseafloor ocean; environmental change and solid earth dynamics. The most ambitious scientific drilling program ever undertaken is the NanTroSEIZE program.

In Japan, the Center for Deep Earth Exploration (CDEX) is a center of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), which provided lead funding for the seismic survey that you will be joining in this expedition and the construction of the deep sea drilling vessel Chikyu, which will be used in the subsequent drilling.
