Description:"The National Centers for Coastal Ocean Science (NCCOS) collaborated with EPA Region 4 Water Protection Division of Coastal and Marine Resources and Wetland Enforcement Section to assess Ocean Dredge Material Dump Sites (ODMDS) as essential fish habitat off the coast of Fernandina Beach, FL. The objectives of this project were to: (1) establish common monitoring protocols for assessing benthic biological habitats and fish communities comparable to surveys previously conducted in the southeast region; and (2) evaluate fishery acoustic surveys and metrics of remotely sensed fish density as measures of the habitat value and beneficial use of rocky dredge material disposed at the Fernandina Beach ODMDS. NCCOS and EPA scientists conducted the research from the NOAA Ship Nancy Foster in 2016 surveying the Fernandina ODMDS with multibeam sonar, in-water diver surveys, and fishery echosounder surveys. Dive teams conducted biological and topographical assessments of the benthic and fish communities on sites identified on the bathymetry maps, focusing on man-made rocky features and natural ledges. The mission was heavily impacted by multiple tropical storm systems, which caused low visibility. For this reason, in-water fish data is not presented in this report"--Executive Summary [doi:10.7289/V5/TM-NOS-NCCOS-238 (https://doi.org/10.7289/V5/TM-NOS-NCCOS-238)]
