The U.S. Science Support Program, associated with the International Ocean Discovery Program, is currently accepting proposals for planning workshops. Proposed workshops should promote the development of new ideas and strategies related to the study of the Earth’s processes and history using scientific ocean drilling. The workshop program encourages wide scientific community involvement to bring a broader and multidisciplinary approach to standing hypotheses and to explore new directions for IODP research and communication. Workshops may focus on a specific IODP scientific theme or topic, or they may focus on a geographic region, integrating multiple topics. Regionally-focused workshops offer opportunities to synthesize scientific results from past expeditions, or to develop drilling proposals for future expeditions. Prospective workshop proponents should consider long-term projected ship tracks in identifying potential geographic areas for focus. Workshops aimed at developing drilling proposals for implementation in the period beyond the current IODP science plan (2023) are welcomed. Funding may be requested for U.S.-based meetings or to support U.S. participants at larger international workshops. Broad-based scientific community involvement, co-sponsorship by related programs, and the active participation of early career researchers are strongly encouraged. The submission deadline is December 1, 2019.
