Seeking the Seeps
From June 12 to July 3, 2019, the USGS sailed onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate fate in...
