38842 NF06_USVI_ROV_TransectLines_metadata Data Set Published / External 37205 SeafloorMapping_USCaribbean_2004toOngoing Project Completed 2006-03 This dataset contains a line shapefile showing the trackline of various Remotely Operated Vehicle (ROV) underwater video transects in the US Virgin Islands and Puerto Rico.NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired Remotely Operated Vehicle (ROV) underwater video data offshore of Buck Island, St. Croix, US Virgin Islands and off of LaParguera, Puerto Rico from 3/21/06 to 4/2/06. Data was acquired with a Phantom S2 ROV operated by NOAA's National Undersea Research Program (NURP) and georeferenced and visually interpreted by CCMA employees. Data is in UTM zone 20N, datum WGS84. This ROV video groundtruthing data was collected as IOCM project NF-06-03 during the second year of an ongoing NOAA scientific research mission in the US Virgin Islands to characterize nearshore coral reef habitats. The mission purpose is to better understand the resources within the surveyed reef habitats, and ultimately develop species utilization models linking physical habitats with biological information. The multibeam backscatter, multibeam bathymetry, and ground truth video footage collected during the 2005 mission will be used internally to characterize sea floor topography and to create benthic habitat maps, helping NOAA meet its mapping commitment to the US Coral Reef Task Force. The resulting publicly-distributed data is also a contribution to the greater scientific community interested in the USVI seafloor. 708 Theme ISO 19115 Topic Category biota Theme ISO 19115 Topic Category environment Theme ISO 19115 Topic Category geoscientificInformation Theme ISO 19115 Topic Category oceans Theme NOS Data Explorer Topic Category Bathymetry/Topography Theme NOS Data Explorer Topic Category Environmental Monitoring Theme BIRNM Theme Benthic Theme Biogeography Theme Biological Cover Theme Buck Theme GIS Theme Geomorphological Structure Theme Groundtruthing Theme Habitat Theme La Parguera Theme Mapping Theme NF-06-03 Theme NOAA Theme NURP Theme Nancy Foster Theme Phantom S2 Theme Puerto Rico Theme ROV Theme Remotely Operated Vehicle Theme Seafloor Theme St. Croix Theme St. Thomas Theme Substrate Theme Transect Theme US Virgin Islands Theme USVI Theme Underwater Video Theme Video Temporal 2006 Spatial Buck Island Reef National Monument Spatial VICRNM Spatial Virgin Islands Coral Reef National Monument National Centers for Coastal Ocean Science Silver Spring MD Data Set As Needed vector digital data These data were prepared by an agency of the United States Government.

The 36 ROV transects collected traversed over 70 km. Transect placement was designed for use in both accuracy assessment and ground truthing. Video (.wmv) and high-resolution digital still photographs (.jpg) were acquired using a downward pointing camera mounted on a Spectrum Phantom S2 Remotely Operated Vehicle (ROV) operated by an experienced team from NURP. Video was collected continuously and still photographs were collected every 30 seconds. The ROV followed pre-determined transect lines and was self-propelled as much as possible, but was towed by the NANCY FOSTER using a 1 inch steel cable when conditions prohibited self-propellation. The camera height off the bottom was kept consistent at approximately 2m and the ROV speed was maintained at 1 meter/second. Most transects were run during daylight hours to guarantee sufficient ambient light levels for visual interpretation, but high powered strobe lights mounted on the ROV were available to supplement ambient light and during occasional night operations. Downward pointing parallel lasers (5cm seperation) were used as scale references. Data Acquisition:Video and still photographs were transmitted via the ROV cable to shipboard hard drives as they were acquired. An ROV-mounted transducer and an acoustic receiver suspended off the side of the ship were used to determine the ROV's relative position to the ship, while the ROV's absolute geographic position was estimated using this relative position and the shipboard GPS. The positional accuracy was estimated to be within 5 m. 2006-03-01T00:00:00 2 Benthic Habitat Interpretation:The benthic habitat was characterized by visual interpretation of both video images and still photographs by three CCMA interpreters. Interpretations were standardized among interpreters by repeatedly interpreting the same still photos and video until structure classes were the same and percent covers were within 5% of each other. After the initial standardization, interpreters were assignedrandom transects to reduce any possible regional bias.Video was used to interpret broad-scale structure and substrate rugosity, since still photos were incapable of providing this data due to their relatively small and top-down field of view. The still photos were used to estimate the percent cover of finer-scale substrate and biological cover components of the benthic habitat.Structure referred to the broad-scale habitat class within the entire field of view. Based on previous benthic habitat work in the area (Kendall et al., 2001 and the NF-04-06 NANCY FOSTER mission) the structure designation was chosen from either 1) colonized pavement, 2) colonized pavement with sand channels, 3) patch reef, 4) spur and groove, 5) scattered coral and rock in sand, or 6) unconsolidated. Substrate described the visible abiotic components of the benthic habitat. The four substrate classes, considered mutually exclusive and exhaustive were 1) consolidated material, 2) sand, 3) rubble (particles ~ 2-10 cm) and 4) rhodoliths. Substrate was measured to the nearest percent of the visible bottom. An estimate of rugosity was approximated by the vertical range of substrate in the field of view and was classified as either high (> 1m), moderate (< 1m and >0.3m), or low (<0.3m).Biological cover referred to the biotic component of the seafloor and was divided among five mutually-exclusive categories differentiated by their size and shape. These were 1) sponge (Phylum Porifera), 2) gorgonian and black coral (Subclass Octocorallia and subclass Ceriantipatharia), 3) hydrocoral and stony coral (Subclass Hexacorallia), 4) fleshy algae and 5) algae veneer/turf. The sum of all cover categories provided an estimate of total colonization. If a biological cover component could not be unquestionably identified as one of the five cover categories it was only added to the total colonization estimate.Photo stills were viewed in ESRI's ArcMap software (ArcGIS 9) with a superimposed 10 X 10 grid shapefile to aid percent cover estimations. Video was viewed simultaneously on a second monitor using windows media viewer. Interpretation results were entered into an EXCEL spreadsheet using a custom VBA script, with a single record for each sample point (i.e. every still photograph taken at 30 second intervals). These sample points and their associated benthic habitat attributes were then imported in ESRI ArcMap and joined into line shapefiles showing transect extents. 2006-04-01T00:00:00 40971 Entity gov.noaa.nmfs.inport:38842 Tyler Christensen 2017-04-05T12:49:13 SysAdmin InPortAdmin 2025-05-15T19:16:12 2018-02-08 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2018-02-08 1 Year 2019-02-08
