Current Expeditions

Expedition 357 aboard the British Royal Research Vessel James Cook to the Atlantis Massif, a periodotite-rich 4000 m high undersea mountain near the mid-Atlantic Ridge, will explore the interaction of mantle-like rock with seawater and heat, including implications for carbon cycling and microbial life.

Expedition 359 (Maldives Monsoon and Sea Level) aboard the JOIDES Resolution will document environmental changes in the Indian Ocean by studying Neogene sediments retrieved from seven drill sites across the Maldives carbonate edifice, with a focus on how change in sedimentation style was driven by fluctuations in sea level and ocean currents.

Recent Expeditions   

Indonesian Throughflow: Exp 356 (July 31 - Sept 30, 2015)

This JOIDES Resolution expedition examined the history of the ocean current system connecting the Pacific and Indian Oceans and their effect on climate over the past 5 million years. 

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. 



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.
