Underwater videos from the Gulfstream Natural Gas Benthic Habitat Survey in 1999 and 2000 (Sea Byte, Inc., 2001) were converted from analog video to digital format at the USGS in St. Petersburg, Florida. The USGS recovered the collection of videos from the Florida Department of Environmental Protection (DEP). Hundreds of hours of analog video tapes were converted to 5-minute digital movie segments and the digital archive was returned to Florida DEP. The archive effort was condensed to this set of sample video clips, maps, and descriptions to demonstrate the range of seafloor types and habitats along the pipeline survey. Maps of video locations and interpretation of video content and seafloor characteristics were prepared by summer interns at the USGS. Available footage was constrained by video quality, depth limits of video collection techniques, and the survey route, and therefore is not an exhaustive inventory of all habitats.
Examples of analog-to-digital video notes can be viewed in the files provided below:
