Monitoring of Methane Emissions at Southern Hydrate Ridge using Deep-Sea Cabled Observatory

Yann Marcon , Deborah Kelley , Blair Thornton , Dana Manalang & Gerhard Bohrmann
Natural methane gas release from the seafloor is a widespread phenomenon that occurs at cold seeps along most continental margins. Since their discovery in the early 1980s, seeps have been the focus of intensive research, partly aimed at refining the global carbon budget. However, deep-sea research is challenging and expensive and, to date, few programs have successfully monitored the variability of methane gas release over several weeks or more. Long-term monitoring is necessary to study...
