Title:
Groundtruthing Notes and Miscellaneous Biological Datasets from Coral Ecosystems Surveys from the Northwestern Hawaiian Islands Rapid Reef Assessment and Monitoring Program of 2000-2002 (NODC Accession 0001448)
Abstract:
The Northwestern Hawaiian Islands Coral Reef Assessment and Monitoring Program (NOWRAMP) began in 2000 with the mission to rapidly evaluate and map the shallow water reef habitats in the NWHI. Utilizing two research vessels Rapture and R/V Townsend Cromwell, researchers spent 30 days at sea visiting each of the ten major islands, atolls and reefs in the remote region of the Hawaiian archipelago. This dataset is a small subset from these cruises. It includes spreadsheet data files on habitats, coral cores, coral species, substrate types, and substrate type percent bottom cover. A descriptive document is also included which was the basis for groundtruthing images from remote sensing. These descriptions give a wide range of information on coral and reef fish species abundance and distribution.

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

    Date: Unknown (process 1 of 1)
    Rapid Ecological Assessments (REA)To maximize the comparability and coverage of field surveys, all REA teams used the same survey procedures, and were deployed over as wide an area as possible. Towboard Team - Towboards allowed trained divers to census and classify habitats over extensive reef areas quickly (about 3 km per dive). These results were then used to select the best areas for intensive benthic and fish assessments by the REA Teams. These surveys are also being used to ground truth the remote sensing imagery. Each towboard team consisted of two divers with separate boards towed behind the same boat. A ditital video camcorder was affixed to each board with one pointing down (90 degrees) and the other point at at a forward angle (20 degrees) to capture a broader spectrum of habitat and substrate information. Divers maintained the cameras 1 meter above the bottom. Each towboard was equipped with paired lasers to project a scale onto the video. Water temperature, depth, and GPS data were recorded continuously during each towboard survey.Fish Team - Each fish team consisted of three divers with two swimming three 25 m long transects per dive. During the deployment leg of the transect, both divers recorded size class-specific counts of all fishes greater than 20 cm within 2 m on each side of the line, while small and cryptic fish (i.e., less than 20 cm) were enumerated by size class during the "swim back" leg. The third diver of the fish team completed four stationary point counts, each within a cylinder having a radius of 10 m, to estimate size and abundance of larger (greater than 25 cm in length) and more mobile fish. This diver also used video to capture "natural" fish assemblages and size information using the attached lasers. Upon completion of the transect surveys, teams swam randomly over the reef to record rare species. Benthic Team - The benthic team surveyed the first two of the fish team's transects to estimate corals, other invertebrates, and algae, but first waited at least 10 minutes to avoid disturbing the fish surveys. The coral expert on each benthic (bottom habitat) team would initially videotape the substrate along each of the first two transects at a height of about 1 m above the center of each line. Later, the algal, invertebrate, and coral experts would swim the lines to record species and collect specimens, additional video, and photographs. All three would then conduct rangom swims near the end of each dive to record other rare species.
