The Ocean Drilling Program (ODP) and its predecessor, the Deep Sea Drilling Project (DSDP), have completed more than 30 years of scientific ocean drilling. Drilling began in the deepest parts of the oceans, in water depths where the oil industry is now drilling. ODP and DSDP technology developments focus on high-quality sampling tools and seafloor observatories. Tool developments include the wireline-deployed advanced piston corer and wireline-deployed tools to measure in-situ physical properties, such as pressure and temperature. These technologies can be used for deepwater site investigations, shallow water-flow assessments, and to establish fluid-flow and pressure monitoring stations at deepwater sites.
