The objective was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of the region’s coral reef ecosystem. These maps will be used to support marine resource management and conservation in the Commonwealth. In addition, the maps will enable change detection in an assessment of the effectiveness of restoration activities on the condition of adjacent coral reef ecosystems. The data contained in this shapefile denote the location of ground validation (GV) sites, which were explored by NOAA field scientists to further refine habitat map classification. In particular, this shapefile includes the location of 511 ground-validation sites that were explored either by video drop camera or by snorkel. 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 optical or acoustic signatures 2. Confirm that the habitat type correlated with a particular optical or acoustic signature remained consistent throughout the entire study area. This information was incorporated into fine-scale maps of marine habitats of Southwest Puerto Rico. 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. In addition, the maps will enable change detection in an assessment of the effectiveness of restoration activities on the condition of adjacent coral reef ecosystems.

Data were collected at 511 ground validation sites in March 2011 aboard a small research vessel. As anchoring at each site was not feasible for rapid assessment, wind and wave effects caused the survey vessel to drift along a transect. Post-processing of the GPS data allowed for a series of points to represent the actual survey location. SWPR_GV_Mean_Site_Locations: Shapefile attribute table FID Internal feature number.

However, it is estimated that horizontal accuracies may be 0 - 20m from the true position of the underwater camera assessment due to line "lay-back" during drift. 511 field positions were occupied and habitat characterizations were conducted for ground validation during this work. Data points were collected with mapping-grade GPS receivers. The data were post processed for differential correction to the Continually Operating Reference System (CORS) station at Coamo, Puerto Rico (PRN4). All attribute information was recorded by the GPS receiver and stored directly in the raw GPS files. This automated process was assumed to be error free. This file is believed to be logically consistent. A first draft benthic habitat map was generated using heads-up visual interpretation and digitization to delineate features on the seafloor with discrete optical or acoustic signatures. During the creation of this first draft map, the cartographer placed discrete points on features in the map that had unknown optical or acoustic signatures. Points were also placed on features with known optical or acoustic signatures (evenly distributed throughout the geographic extent of the map) to confirm that the habitats associated with these signatures remained consistent through the area of interest. These two types of points were labeled as "ground validation" sites and were visited in the field. 2011-01-01T00:00:00 Laurie Bauer Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch Project Manager (301) 713-3028 1305 East West Highway, N-SCI-1, SSMC 4, 9th Floor Silver Spring MD 20910 USA Laurie.Bauer@noaa.gov processor NOAA scientists explored these ground validation locations using using a manually operated drop camera, underwater still camera and look bucket. The resulting GPS, video and photographic information was processed, analyzed and used to classify each distinct habitat polygon. At the start of every morning, the boat captain selected a general region to begin the day's work. Navigating to field locations was accomplished using a Garmin GPS 76 device with the uploaded GV site coordinates. The boat captain maneuvered the vessel to within 5 m of the target location and made every effort to maintain that location without jeopardizing crew and equipment safety. Once on site, NOAA scientists would simultaneously deploy a SeaViewer Sea-Drop 950 camera and begin logging a waypoint on a Trimble GeoXT GPS receiver. While the video camera was capturing bottom imagery, an observer viewed the video real-time on a Panasonic Toughbook aboard the survey vessel. They categorized each site according to the levels of the habitat classification scheme: major and detailed geomorphological structure, major biological cover, percent major biological cover and percent coral cover. Data was entered into a custom data dictionary generated in Trimble Pathfinder Office software and loaded onto the Trimble data logger. 2011-01-01T00:00:00 Laurie Bauer Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch Project Manager (301) 713-3028 1305 East West Highway, N-SCI-1, SSMC 4, 9th Floor Silver Spring MD 20910 USA Laurie.Bauer@noaa.gov processor Trimble Pathfinder Office software was used to post process and differentially correct the raw GPS data to the Continually Operating Reference System (CORS) station at Coamo, Puerto Rico (PRN4). 2011-01-01T00:00:00 Laurie Bauer Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch Project Manager (301) 713-3028 1305 East West Highway, N-SCI-1, SSMC 4, 9th Floor Silver Spring MD 20910 USA Laurie.Bauer@noaa.gov processor Precisely positioned GPS positions and its associated transects were viewed in a GIS to enhance the accuracy of the draft benthic habitat map.
