The ship JOIDES Resolution, which is conducting Expedition 385 of the International Ocean Discovery Program (IODP, 2013~2023), left San Diego, Calif., on Sept. 22 for Guaymas Basin in the Gulf of California in Mexico for two months of scientific ocean drilling with Prof. Jiang Shijun of JNU's Institute of Groundwater and Earth Sciences aboard as an invited scientist.
Jiang is leading a team of paleontologists in charge of stratigraphic chronology research of the ocean floor, providing a geologic timescale for other research on this expedition. Having experienced three previous IODP expeditions, he among the Chinese who have participated in the most IODP collaborative programs. This is the second expedition on which he has represented JNU.

Thirty-two scientists from nearly 10 countries, including China, the United States, France, Germany, Britain and Japan, are on this voyage. They are studying the interrelationships among sedimentation, magmatism, fluid and microbial processes, and carbon cycle through high-resolution sedimentary records, combined with seismic profiles and logging data, and comparing them with those in similar areas on the edge of the sea. 

With the biggest scale and the longest history among international cooperative research projects in earth science, IODP has broken through the boundary between the crust and mantle for the first time. It aims to deduce the evolution of the ocean and the atmosphere, explore the deep-seabed biosphere, reveal the interaction between the Earth's surface and its internal processes, and study the undersea disaster process by drilling samples from the deep seabed core and sediment.
