Recent Expeditions   

Arabian Sea Monsoon: Exp 355 (March 31 - May 31, 2015)

This JOIDES Resolution expedition studied the co-evolution of the SW Asian Monsoon, one of Earth's strongest climatic patterns, with mountain building and erosion in Asia over multiple time scales.

Bengal Fan: Exp 354 (Jan 29 - Mar 31, 2015)

This JOIDES Resolution expedition explored relationships between the Himalyan Orogeny, development of the Asian Monsoon, global climate, and the carbon cycle.

Indian Monsoon Rainfall: Exp. 353 (Nov 29, 2014 - Jan 29, 2015)

 JOIDES Resolution Expedition 353 explored how monsoon patterns have influenced global ice volume and greenhouse gas concentrations over geological time. 

Nankai Trough Seismogenic Zone Experiment Stage 3: Exp.348 (13 September - 29 January 2014)

In Expedition 348, Chikyu advanced the riser hole at Site C0002 to a record-setting 3056 m below the sea floor, the deepest in scientific ocean drilling history, and cased it for future access to the deep interior of an active convergent margin.

Baltic Sea Paleoenvironment: Exp.347 (Sept 12 - Nov 1, 2013; onshore science party Jan 22 - Feb 19, 2014)

This expedition used the Greatship Manisha to study the paleoenvironmental evolution of the Baltic Sea Basin through the last glacial cycle.



IODP Facilities

Exploring Our Planet

The International Ocean Discovery Program: Exploring the Earth under the Sea (IODP) continues over five decades of international collaboration to recover geological data and samples from beneath the ocean floor to study the history and dynamics of Planet Earth. IODP is guided by the science plan Illuminating Earth's Past, Present, and Future.
