1000’s of Methane Seeps: Expedition to discover and sample methane gas along the NW coast
Scientist(s):
June 12 - 29: PMEL scientists with the Earth-Ocean Interactions (EOI) Program will join the E/V Nautilus to continue to survey methane sites from Northern California to Washington using multibeam sonar and a remotely operated vehicle in order to fully document and characterize this region. Up until a few years ago, only 100 methane “seep sites” had been identified primarily by fisherman using their fish-finders observing the acoustic reflections of the gas bubbles. Beginning in 2016, EOI scientists began a more systematic mapping of the seeps using new sonar technology on the E/V Nautilus,
