AB: The NSF Major Research Equipment and Facilities Construction project termed the Ocean Observatories Initiative seeks to develop a Global Scale Observatory to support a sustained presence in a variety of deep-water areas of the world ocean. The observatory will sample different physical, geodynamic, biogeochemical, and ecosystem regimes. The infrastructure is transformative in supporting the observation of transient and emergent phenomena and in making simultaneous, real-time measurements of atmospheric, physical, biogechemical, ecological and geodynamic observations with interactive control. One of the proposed platforms is an Extendable Draft Platform (EDP), which couples spar buoy behavior with a self-installing approach to mooring. The platform provides real-time telemetry capability to shore via satellite, continuous telemetry and power supply to the water column and seafloor, and substantial power on board the buoy. The platform is not occupied except for annual servicing and can be towed to site with a large UNOLS vessel. Larger-scale versions of the EDP are attractive for hydrocarbon recovery in the deep sea. Scripps Institution of Oceanography and Technip have partnered in the design, construction, and testing of the first of these platforms prior to the platform's use in the OOI in the mid- Atlantic.
