THE FUTURE OF REAL-TIME MONITORING OF METHANE HYDRATE DEPOSITS AT ACTIVE CONTINENTAL MARGINS: THE OOI CABLED OBSERVATORY AT HYDRATE RIDGE

Hydrate Ridge is characterized by an extensive system of subsurface gas hydrate deposits, active plumes, and extensive biological communities. Previous studies of its subsurface geology and these seep-supported benthic communities highlighted the need for an integrated, synoptic, and long-term approach to the study of carbon cycling in such continental margins. In 2013, the cabled observatory component of NSF’s Ocean Observatories Initiative (OOI), known as the Regional Scale Nodes (RSN), will begin deploying an array of seafloor instruments at Southern Hydrate Ridge. Upon commissioning in 2014, RSN will provide unparalleled high power (3 kW) and bandwidth (1 Gbps) to a variety of instruments (e.g. upward-looking ADCP, mass spectrometer, camera, seismometer array), facilitating real-time and synoptic measurements of physical, chemical, geological, and biological processes at the seafloor. RSN’s built-in expandability and 25-year lifetime will provide unprecedented opportunities for long-term high-resolution studies, furthering our understanding of gas hydrates and carbon cycling in such systems and potential global effects associated with tectonic activity and climate change.
