Long-Term Monitoring of Gas Emissions at Southern Hydrate Ridge

Methane bubble emissions detected by the MARUM overview sonar over the Southern Hydrate Ridge summit. The location and size of the bubble plumes vary considerably over time.

Identifying the parameters that control or influence seabed methane release is important to refining understanding of the carbon cycle. Data from the Regional Cabled Array are providing time-series required to quantify the flux of methane from the seafloor.
