IODP drilling proposals were considered Active when they were under review by the Science Evaluation Panel (SEP), being considered for scheduling by the program's Facility Boards (JRFB, EFB, CIB), or in the SEP Holding Bin (HB). Proposals that had been unresponsive for 5 years were subject to deactivation. This table was last updated on March 2025 and represents active proposals at the end of IODP. You can download graphs and pie charts of proposal statistics.
