Video was collected between 03/18/2010 and 04/05/2010 at 104 locations within two selected areas of seafloor south of St. Thomas and St. John, USVI. These videos will be manually classified into different habitat classes, and integrated with the abiotic data collected by the acoustic SoNAR (sound navigation and ranging) systems to develop a benthic habitat map for the U.S. Caribbean. Habitat maps describe the location of habitat features (in relation to the shoreline), their physical composition and the types of organisms that colonize them. Fundamentally, habitat maps provide critical information about the extent, health and composition of marine resources, which is vital for communicating information about the distribution and abundance of species to resource managers, scientists and the public. Habitat maps also support an increasing number of landscape ecology studies, as well as the process of marine spatial planning, including the design and evaluation of marine protected areas (MPAs). The objective of this ground validation (GV) effort, conducted by NOAA's Center for Coastal Monitoring and Assessment Biogeography Branch, in collaboration with multiple federal, state, territory, academic and private sector partners, was to acquire spatially-explicit information about the geomorphological structure, biological cover and live coral cover of the seafloor in the U.S. Caribbean. Extensive field work is needed to create high-quality benthic habitat maps because it enhances the accuracy of habitat attribution and (to a lesser degree) habitat delineation. Consequently, ground validation locations were targeted by the cartographer to satisfy the following objectives: (1) Explore features in the imagery with unknown or confusing acoustic signatures; (2) Confirm that the habitat type correlated with a particular acoustic signature remained consistent throughout the entire study area. This information will be incorporated into a fine-scale assessment of the status, abundance, and distribution of marine habitats in the U.S. Caribbean. completed NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian notPlanned Geographic Information > Habitats theme CoRIS Discovery Thesaurus EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Mapping > Habitat Mapping theme CoRIS Theme Thesaurus COUNTRY/TERRITORY > United States of America > Puerto Rico > Culebra Island (18N066W0002) COUNTRY/TERRITORY > United States of America > Puerto Rico > Vieques > Vieques Island (18N065W0002) COUNTRY/TERRITORY > United States of America > U.

All data point characteristics were recorded in the GPS data logger automatically and seamlessly transferred to ArcGIS shapefiles using Trimble Pathfinder Office software. Attributes are all expected to be correct. Horizontal Positional Accuracy It is estimated that horizontal accuracies may be 0 - 20m from the true position of the underwater camera assessment due to line "lay-back" during drift. Completeness Report 104 field positions were occupied and habitat characterizations were conducted for ground validation during this work. Conceptual Consistency Data points were collected with mapping-grade GPS receivers. The data were post processed for differential correction to the Continually Operating Reference System (CORS) station at St. Thomas, USVI (VITH). All attribute information was recorded by the GPS receiver and stored directly in the raw GPS files. This automated process was assumed to be error free. This file is believed to be logically consistent. As the multibeam survey was carried out, a NOAA contractor would examine the bathymetry, produced as a CARIS BASE Surface, and placed discrete points on features on the surface that had unknown acoustic signatures. Points were also placed on features with known acoustic signatures (evenly distributed throughout the geographic extent of the map) to confirm that the habitats associated with these signatures remained consistent through the area of interest. These two types of points were labeled as "ground validation" sites and were visited in the field. | Source Produced: DropCamera_2010_Transects_Lines.shp 2010-01-01T00:00:00 NOAA scientists explored these ground validation locations using a manually operated drop camera. The resulting GPS and video information was processed and analyzed in preparation for use in habitat delineation and classification. At the start of every morning, the chief scientist selected a general region to begin the day's ground validation work aboard a small launch. Navigating to field locations was accomplished using a Garmin GPS 76 device with the uploaded GV site coordinates. The boat captain maneuvered the vessel to within 5 m of the target location and made every effort to maintain that location without jeopardizing crew and equipment safety. Once on site, NOAA scientists would simultaneously deploy a SeaViewer Sea-Drop 950 camera and begin logging a waypoint on a Trimble GeoXT GPS receiver. While the video camera was capturing bottom imagery, an observer viewed the video real-time on a SeaViewer DVR viewer aboard the survey vessel. They categorized each site according to the levels of the habitat classification scheme: major and detailed geomorphological structure, major biological cover, percent major biological cover and percent coral cover. Data was entered into a custom data dictionary generated in Trimble Pathfinder Office software and loaded onto the Trimble data logger. | Source Produced: DropCamera 2010 GroundValidation Videos 2010-01-01T00:00:00 Trimble Pathfinder Office software was used to post process and differentially correct the raw GPS data to the Continually Operating Reference System (CORS) station at St. Thomas, USVI (VITH). | Source Produced: DropCamera_2010_Transects_Lines.shp 2010-01-01T00:00:00 Source Contribution: NF10 DropCamera Transects | Source Geospatial Form: vector digital data | Type of Source Media: videotape DropCamera 2010 GroundValidation Videos 2010-01-01 publication Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch 2010 Source Contribution: GPS data, which were originally recorded as code-phase signals in Trimble SSF format, were differentially post-processed to the Continually Operating Reference System (CORS) station in St. Thomas, USVI (VITH). | Type of Source Media: GPS data DropCamera_2010_Transects_Lines.shp Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch 2010 Source Contribution: NF10 Drop Camera Trimble Data | Source Geospatial Form: vector digital data | Type of Source Media: online DropCamera_2010_Transects_Lines.shp 2010-01-01 publication Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch 2010
