 As a result of this regional planning, the JR has been able to address several science plan themes on multiple, complementary expeditions.For example, Expeditions 350, 351, and 352, as well as Expedition 371 addressed the fundamental question of how the subduction process initiates.Likewise, two years of drilling in the western Pacific and Indian Oceans resulted in multiple expeditions that address the origin and initiation of the Monsoon climate system.
