Scientists on an ocean drilling expedition off the western coast of Costa Rica

April 27, 2010
Scientists on an ocean drilling expedition off the western coast of Costa Rica, Central America, discuss cores in the core lab on board the scientific drillship JOIDES Resolution. The expedition was conducted by Texas A&M University's Ocean Drilling Program.

In the background sampling a core are: ODP leg project manager Adam Klaus and ODP curator Paula Weiss.

More about this Image The Ocean Drilling Program (ODP) is funded by the National Science Foundation and 22 international partners. ODP explores on a global scale, the Earth's crust beneath the ocean in order to learn more about the composition, structure and history of the submerged portion of the Earth's surface. The drilling process involves collecting and logging geologic samples from the floor of deep ocean basins through rotary coring and hydraulic piston coring. The logs and samples of the cores are available to qualified scientists throughout the world for research projects.

Samples have been taken at various sites, including the North Atlantic Ocean, Norwegian Sea, Mediterranean Sea, southern and equatorial Atlantic Ocean, Pacific Ocean off the west coast of South America, Weddell Sea off Antarctica, Indian Ocean and western and equatorial Pacific Ocean.

The general contractor for the overall management and operation of the ODP is Joint Oceanographic Institutions, Inc. (JOI), a consortium of major U.S. oceanographic institutions. The drilling operations are managed by Texas A&M University; logging is managed by the Lamont-Doherty Earth Observatory at Columbia University. (Year of image: 2002)
