Description:

Abstract:

Benthic habitats of the moderate-depth marine environment in and around the Virgin Islands Coral Reef National Monument were mapped using a combination of semi-automated classification and visual interpretation of acoustic imagery. The objective of this effort, conducted by NOAA's Center for Coastal Monitoring and Assessment - Biogeography Branch in partnership with the U.S. National Park Service (NPS), was to provide spatially-explicit information on the moderate-depth habitat types, biological cover and live coral cover south of St. John. The data contained in this shapefile denote the position of the remotely operated vehicle (ROV) as it followed 13 predetermined transects. These ground validation (GV) transects were explored by NOAA field scientists to further refine habitat map classification.

Purpose:

Extensive field work is needed to create high-quality benthic habitat maps because it enhances the accuracy of habitat attribution and (to a lesser degree) habitat delineation. Given the importance of field work, the primary purpose of this survey data was to explore and verify existing habitat information on the seafloor. In particular, these ground validation locations were targeted by the cartographer to satisfy the following objectives:

1. Explore features in the imagery with unknown or confusing acoustic signatures 2. Confirm that the habitat type correlated with a particular acoustic signature remained consistent throughout the entire study area.

This information was incorporated into a fine-scale assessment of the status, abundance, and distribution of moderate-depth marine habitats of St. John. The NOAA effort provides the U.S. National Park Service with increased technical capacity for ocean exploration, management, and stewardship. Direct implications to management measures include evaluation of management efficacy, a spatial framework for improved monitoring sampling design, improved assessment of human-use impacts, and marine spatial planning to support alternative marine protected area boundary alternatives.

Supplemental_Information:

The creation of high-quality benthic habitat maps required extensive field work to enhance accuracies of habitat attribution and, to a lesser degree, habitat delineation. Data were collected along 13 ground validation transects during a two-week field mission from 2/1/2005 - 2/12/2005 aboard the NOAA Ship Nancy Foster. Post-processing of the GPS data allowed for a series of points to represent the actual survey location.

Logical_Consistency_Report:

A transducer attached to the ROV and an acoustic receiver (suspended off the side of the ship) were used to determine the ROV's relative position to the ship. The ROV's absolute geographic position was estimated using this relative position and the shipboard differentrial GPS. The positional accuracy was estimated to be within +/-5 m.

This file is believed to be logically consistent.

Process_Step:

Process_Description:

For the 2005 mission, the GV transects were systematically placed over the study area to include as many benthic habitat features and transition zones as possible. Distinct features and transitional areas were identified by visual examination of fine-scale multibeam bathymetry data collected in 2004 and moderate-scale GEODAS bathymetry data (GEODAS, 2005). The bathymetry data were divided into distinct benthic habitats using variations in depth, roughness and spatial patterning (ridges, bumps, troughs, regular undulations, etc.).

Process_Date: 2005

Process_Step:

Process_Description:

Georeferenced underwater video and photographs were acquired using a video camera and high-resolution digital still camera mounted on a Spectrum Phantom S2 ROV. High powered strobe lights mounted on theROV were used to supplement ambient light levels during the day and served as the only source of light during night operations. Data from the cameras were transmitted and immediately recorded to a computer's hard drive. Video data were collected during an entire transect, and still photos were collected every 30 seconds. The forward-facing video camera was pointed at a 45 degree downward angle to give ROV pilots a view of upcoming obstacles and researchers a view of the benthic habitat. The ROV's height above the substrate and speed were approximately 2 m and 1 m/s, respectively. The ROV pilot attempted to keep the ROV height and speed as constant to standardize the field of view and spatial resolution of interpretations. Two downward pointing parallel lasers separated by 5 cm and the scale of habitat features and organisms were used to estimate height off the bottom. Still photo images were acquired using a downward pointed camera.
