South Central Coast California GIS Products Metadata
Compiled by Seafloor Mapping Lab at California State University Monterey Bay

This document provides a general metadata summary of the marine habitat mapping data for Northern California collected for the California Seafloor Mapping Program (CSMP). Detailed metadata are provided in xml format with each individual data file. 

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. 

Data products are presented at distinct spatial resolutions based on discrete depth ranges: 2m resolution for data from the 0-85m depth range, 5m resolution for 80-250m depth range, and 10m resolution from depths of 230-1200m. A comprehensive 5m data set was produced for the total survey coverage only if per block data exceeded 85m depth and 5m resolution products 
were included.

MBES and side scan data for the South Central Coast nearshore region were acquired using a combination of sonars (200 KHz/ 400 KHz Reson 7125, 468KHz SEA SWATHplus) collected aboard the R/V VenTresca by the Seafloor Mapping Lab at California State University Monterey Bay.  Prior to data collection, a series of planned survey lines were created using the survey navigation and planning software Hypack 2008 from Hypack, Inc. An Applanix POS/MV 320 v4 system was used to provide position and attitude data during data collection and accounted for vessel motion such as heave, pitch, and roll (position accuracy ± 2m, pitch, roll and heading accuracy ±0.02°, heave accuracy ± 5% or 5cm) with input from a NAVCON 2050 GPS. KGPS altitude data were used to account for tide cycle fluctuations and sound velocity profiles were collected with an Applied Microsystems SVPlus sound velocimeter. Data acquisition, post-processing, and final products derived from multibeam bathymetry data were handled by the Seafloor Mapping Lab at CSUMB.
