Marine Geophysical Data -- Point Arena to Cape Mendocino

This data release includes marine geophysical data collected on three research cruises conducted in 2010 and 2012 between Point Arena and Cape Mendocino. The overall goal of this research is to better understand the northernmost section of the San Andreas Fault (SAF). In 2010, the USGS collected seismic-reflection profiles crossing the SAF at 1 km spacing from Point Arena to Fort Bragg (survey B-5-10-NC). Then, Oregon State University (OSU) and U.S. Geological Survey (USGS) jointly collected seismic-reflection data crossing the SAF at 1 km spacing from offshore Fort Bragg to Point Delgada (survey C-1-10-NC). In 2012, OSU and USGS jointly collected additional seismic-reflection and marine magnetic data west of the SAF between Point Delgada and Punta Gorda, and east of the SAF between Point Delgada and Fort Bragg (survey B-04-12-NC). Approximately 1,605 km of single-channel, seismic-reflection data between Point Arena and Punta Gorda were collected during the three cruises.
