The Integrated Ocean Drilling Program stores core samples for future investigations at four repositories.

The Gulf Coast Repository at Texas A&M University in College Station, Texas, U.S.A., houses cores from the Pacific (Pacific plate east of western boundary); Caribbean Sea and Gulf of Mexico; Southern Oceans (S of 60° except Kerguelan Plateau)

The Bremen Core Repository at the University of Bremen, Federal Republic of Germany, houses cores retrieved from the Atlantic and Arctic Oceans (north of Bering Strait).

The Kochi Core Repository at Kochi University, Japan houses cores from the Pacific (west of western boundary of Pacific plate); Indian Ocean (N of 60°S), all of Kerguelan Plateau, and the Bering Sea.

Scientists worldwide request samples or visit the repositories to study the cores on site.
