High-resolution studies of the eastern equatorial Pacific

The nature of scientific drilling changed with the transition from the Deep Sea Drilling Project (DSDP) to the Ocean Drilling Program (ODP). As drilling technology, analytical techniques, and mathematical and conceptual models evolved, the DSDP's regional and reconnaissance-oriented drilling gave way to the new orientation toward global problems adopted by the ODP. Through input from its advisory panels and international workshops, ODP has defined and ranked a series of key scientific questions to be addressed by ocean drilling, and it has chosen a series of globally distributed drill sites to answer them.
