Transgressive Contours--Pigeon Point to Monterey, California

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-11-18T00:00:00Z
This part of DS 781 presents data for the transgressive contours for the depth-to-transition map of the Pigeon Point to Monterey, California, map region. The vector file is included in T "TransgressiveContours_PigeonPointToMonterey.zip," which is accessible from https://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, S-N1-09-MB, and S-06-11-MB) supplemented with outcrop and geologic structure from DS 781. The resulting grid covers was subtracted from regional bathymetry to determine the depth to the transitional surface. Contours at 5-meter intervals were derived from this grid.
