This raster dataset is a 2-meter digital bathymetric slope grid containing data for the North-Central Monterey Bay region of California. The survey for North-Central Monterey Bay was conducted conducted on September 3, 5-11, 2009; October 21-23, 2009; November 1, 3, 5-6, 8-12, 2009. This layer was created as part of the California Seafloor Mapping Project.Marine data offered here represent the efforts of a comprehensive state waters mapping program for California launched by the California State Coastal Conservancy, Ocean Protection Council, Department of Fish and Game, and the NOAA National Marine Sanctuary Program. The ultimate goal is the creation of a high-resolution 1:24,000 scale geologic and habitat base map series covering all of California's 14,500 km2 state waters out to the 3 mile limit, and support of the state's Marine Life Protection Act Initiative (MLPA) goal to create a statewide network of Marine Protected Areas (MPAs). This statewide project requires, involves and leverages expertise from industry, resource management agencies and academia. The tiered mapping campaign involves the use of state-of-the-art sonar, LIDAR (aerial laser) and video seafloor mapping technologies; computer aided classification and visualization; expert geologic and habitat interpretations codified into strip maps spanning California's land/sea boundary; and the creation of an online, publicly accessible data repository for the dissemination of all mapping products.
