Transgressive Contours--Pigeon Point to South Monterey Bay, California

This part of DS 781 presents data for the transgressive contours for the Pigeon Point to South Monterey Bay, California, region. The vector file is included in "TransgressiveContours_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 depth to the transgressive surface of the Last Glacial Maximum ranges between 1.5 and 144 meters. Contours at 5-meter intervals were derived from this grid.
