The Integrated Ocean Drilling Program (IODP) 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.
Geology.com publishes a story about the Costa Rica Seismogenesis Project (CRISP) expedition carried out by the scientific drilling vessel JOIDES Resolution, and the nearly 1,500 m of sediments collected from the ocean floor off the coast of Costa Rica, revealing records of some two million years of tectonic activity along a seismic plate boundary.
