Field Activity 2019-001-FA

Identifier 2019-001-FA
Alternate names 2019-619-FA
Purpose ROV and geophysical studies of methane seepage on the Cascadia margin
Location U.S. Cascadia (Pacific Northwest) margin, offshore Washington and Oregon
Summary Telepresence-enabled cruise with ROV dives from southern Oregon margin through Grays Canyon, Washington, including CTDs, overnight multibeam and EK80 seafloor/water column mapping, and seafloor experiments led by GEOMAR and NOAA PMEL. Extensive web presence on USGS websites.
Info derived seafloor maps, subseafloor maps, gas seep characterization, methane flux, methane oxidation rate
Comments This was a competitively chosen project for which Schmidt Ocean Institute is providing about $1 million in shiptime on the global class R/V Falkor. We are responsible for travel, shipping, other science, overtime, etc.
