The South Korean Research vessel R.V. Isabu is carrying annual research cruises to the Seychelles-Chagos Thermocline Ridge in the Indian Ocean. The cruises on this state-of-the-art vessel will run until at least 2026. The potential exists for US PIs to participate in these cruises. See the Science Plan for the Korea-US inDian Ocean Scientific (KUDOS) Research Program, which will give you some idea of the kinds of research questions that could be addressed.
