Summary: Beginning with Project Mohole in the 1960s, ocean drilling technology has been used by scientists to revolutionize understanding of dynamic Earth processes on geological to societal timescales. The Deep Sea Drilling Project (1968-1983) was mostly exploratory in nature. Initially a US effort, with the National Science Foundation providing the funding and the drilling vessel (D/V) Glomar Challenger, DSDP recovered sedimentary records from the world's oceans. The addition of international partners for the International Phase of Ocean Drilling (1975-1983) added an emphasis on penetrating oceanic crust beneath sediments. IPOD led the way for successful international collaboration that continues today. The Ocean Drilling Program (1985-2003) was more thematically-driven, attracting 22 international partners, although the US continued to provide the majority of the funding and the more capable leased D/V JOIDES Resolution. Expeditions were selected based on proposals submitted by the scientific community in response to multi-year science plans developed in international workshops. Planning for the subsequent program revealed scientific objectives requiring increased drilling capabilities. The Integrated Ocean Drilling Program (2003-2013) involved three types of drilling platforms: the refitted JOIDES Resolution provided by the US, a new riser drillship provided by Japan (D/V Chikyu), and mission specific platforms (MSPs) provided periodically by the European Consortium for Ocean Research Drilling primarily to access shallow waters and high latitudes. IODP had a strong central management office for integrative activities supported by international commingled funds. However, limited funding never enabled full-time operations of both drilling vessels and an annual MSP operation. Today, the International Ocean Discovery Program (2013-2023) continues with the same three drilling capabilities but with a simplified, collaborative funding model. While scientific ocean drilling has evolved over its five decades, it continues to be a model of rigorous, proposal-driven, peer-reviewed, transformative science undertaken by international, interdisciplinary research teams. This presentation will summarize the accomplishments and challenges of all four phases of scientific ocean drilling.
