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).

Person who carried out this activity:
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.
Depth recorded for each image is taken directly from the submersible's depth recorder, which measures in increments of 3 cm (0.1 feet).
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.
These data are believed to be logically consistent, though no tests were performed.
