Description: The kelp and subtidal reef investigation was conducted from May 2‐4, 2014, within the Morro Bay study area. Surveys were conducted using multiple methods including interferometric sidescan sonar to locate and map hard bottom habitat features and kelp beds. Visual observations were made during low tide to identify kelp and macroalgal species and to photograph habitats. A drop camera and a remotely operated vehicle (ROV) were used to verify characteristics of the reefs and to identify additional algal species characterizing the kelp communities.Following completion of the survey, sidescan sonar traces were joined together and geographically registered. Features were then digitized as a theme over the aerial image. In order to provide spatial context to the reefs and kelp habitat, other habitat features were mapped on the overall sand bottom mosaic. This included mapping of riprap shoreline and jetties, and artificial structures that supports macroalgal communities and can support canopy and understory kelp during various years and under various environmental conditions. Sand was mapped as the base habitat in the survey area.
