Seismic Project Information MGL1212

Part of the COAST (Cascadia Open-Access Seismic Transects) project, this 2012 R/V Langseth cruise served as an open-access, open-participation 2D seismic survey of the Cascadia subduction margin off Grays Harbor, Washington, USA, collecting data that will provide background information for siting and planning any future 3D work on this part of the margin. The objectives were to image the plate boundary, to identify downdip variations in the character of subduction thrust associated with seismic rupture, to characterize the subduction interface, and to quantify pore fluid pressure, fluid budgets, and upstream inputs to the ETS zone.
