Title:
Jeff's Reef Oculina Banks Clelia Dive 606 2001 Digital Imagery - Captured from Videotapes taken during Submersible Dives to the Oculina Banks Deep Sea Coral Reefs (NODC Accession 0047190)
Abstract:
Digitial imagery, mpegs and jpegs, captured from mini-DV magnetic videotapes collected with an underwater 3-chip CCD color video camera, deployed from the research submersible, Clelia (owned by Harbor Branch Oceanographic Inst.). Digital clips captured at a minimum of 150 dpi; mpeg file sizes generally range from 0.5 to over 2 Mb. Digital Imagery Captured from Videotapes Recorded during 2001 Clelia Submersible Dives to the Oculina Banks Deep Sea Coral Reefs. The data presented in the Oculina Banks Geographic Information System (OGIS) was collected as part of a cooperative project between: the National Oceanographic and Atmospheric Administration's (NOAA) Undersea Research Program, NOAA Fisheries (also primary sponsor of OGIS), NOAA Ocean Service, NOAA Ocean Exploration Program, the U.S. Geological Survey (USGS)-- Coastal and Marine Geology Program, Harbor Branch Oceanographic Institution (HBOI) and Florida State University. An Oculina Geographic Information System (OGIS) provides a comprehensive, interactive data source for the Oculina Banks Habitat Area of Particular Concern (OHAPC), a marine protected area off the east coast of Florida in 70 to 120 meters of water depth. Data layers include; multi-beam bathymetry, single-beam bathymetry, sidescan mosaics, sediment analyses, resulting interpretative maps of habitat types, video and still imagery from submersible (human occupied and remotely operated vehicles) dive transects and point counts (fish and habitat cover), and dive narratives. This metadata record relates to images captured from videotapes recorded during the 2001 "Islands in the Stream" Expedition, on fourteen "Clelia" submersible dives.
Supplemental_Information:
Clelia 606 has 5 still and 5 video clips. Digitized images ( video clips and still images) were captured using a digital capture board at a resolution of at least 150 dpi. Submersible dive narratives (see oculina_clelia_dive_606_2001.txt metadata record). include the camera used to record the relevant tape. The images are not precisely located, but assigned to an estimated center location of a dive. The dive narratives compiled by J. Arcuri also provide a general description of the habitat and fish populations on each submersible dive.

Why was the data set created?

The videotapes were taken to support OGIS. The goal of OGIS is to provide interactive access to a variety of data sources that characterize fish populations and habitat condition in the OHAPC for use by fisheries managers, scientists and the general public. The digital imagery provides visual evidence of the representative habitat types and fish populations in the OHAPC, and ground-truth data for the acoustic surveys. Video clips and still images are accessible in OGIS through the videos.shp and photos.shp shapefiles. They are also referenced in the videotape observation logs/narratives prepared by J. Arcuri ##(see clelia2001diveobs.met record)##. Digital Imagery Captured from Videotapes Recorded during 2001 Clelia Submersible Dives to the Oculina Banks Deep Sea Coral Reefs record).

  2. How were the data generated, processed, and modified?

    Date: 31-Dec-2002 (process 1 of 1)
    Imagery captured from videos as jpg stills or mpg clips were selected based on how well they represented the habitat and fish seen on the dive. Some imagery recorded significant events (e.g., juvenile grouper, courtship behavior).

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

    Position assigned to each point is an estimated center location of the dive. This was calculated based on the complete dive track provided by the ship. The dive track is calculated using the ship's Differential GPS and a slant-range positioning system that estimates bearing and range to the submersible; estimated accuracy of each calculated position along the dive track is plus/minus 10 meters.

  3. How accurate are the heights or depths?

    Depth recorded for each image is taken directly from the submersible's depth recorder, which measures in increments of 3 cm (0.1 feet).

  4. Where are the gaps in the data? What is missing?

    The selected images are not a complete record of all the imagery collected during the dives. They were subjectively selected based on how well they represented key habitat types and fish species seen on the dive.

  5. How consistent are the relationships among the observations, including topology?

    These data are believed to be logically consistent, though no tests were performed.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None
Use_Constraints: Not for legal use.
