Objective - create a comprehensive coastal/marine geologic and habitat base map series for all state waters (MHHW - 3nm).
State Funding - 2006 Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006 (Proposition 84).
Federal Funding - NOAA National Ocean Service, Office of Coast Surveys; U.S. Geological Survey Coastal and Marine Geology Program; and American Recovery and Reinvestment Act.
The CSMP is a cooperative partnership between State, Federal agencies, Universities, and Industry including,
Bathymetry and Backscatter Data Collection - ship-based, high-resolution sonar data collection for all parts of the coast currently unmapped as well as potentially airplane-based nearshore lidar data. Visit progress page.
Data ground-truthing - video, still photography, or physical sampling of the seafloor. Visit progress page.
Subbottom profiling - High resolution seismic-reflection profiling to determine thickness and distribution of sediment and other geologic units, locations of active faults and folds, and other features. Visit progress page.
GIS Data and Map Production - creation of GIS databases and multi-sheet folio map sets (1:24,000 scale), which will include bathymetry, geologic and habitat interpretation maps spanning the entire California land/sea margin. Visit map sheets page.
Data Management and Dissemination - creation of an online data repository for the public dissemination of all digital data and map products covering the California state waters. Visit GIS data & metadata page.
