Isopachs--Pigeon Point to South Monterey Bay, California

This part of DS 781 presents data for the isopachs for the Pigeon Point to South Monterey Bay, California, region. The vector data file is included in "Isopachs_PigeonPointToSouthMontereyBay.zip," which is accessible from http://dx.doi.org/10.5066/F7N29V0Z
As part of the USGS's California State Waters Mapping Project, a 50-m grid of sediment thickness for the seafloor within the limit of California’s State Waters between Pigeon Point and Southern Monterey Bay was generated from seismic-reflection data collected in 2009 and 2010 (USGS activities (S-15-10-NC and S-N1-09-MB) supplemented with outcrop and geologic structure from DS 781. The resulting grid covers an area of approximately 850 sq km. The volume of sediment accumulated since the Last Glacial Maximum is approximately 7,700 million cubic meters. Contours at 2.5-meter intervals were derived from this grid.
