This shapefile denotes the location of underwater photos and/or video that were collected by NOAA scientists using a Spectrum Phantom S2 ROV (remotely operated vehicle). Photos and/or video were collected between 03/26/2009 and 04/02/2009 along 18 transects south and east of Isla de Vieques, Puerto Rico in the U.S. Caribbean. These photos and videos will be manually classified into different habitat classes, and integrated with the abiotic data collected by the acoustic sonar (sound navigation and ranging) systems to develop a benthic habitat map for the U.S. Caribbean. Habitat maps describe the location of habitat features (in relation to the shoreline), their physical composition and the types of organisms that colonize them. Fundamentally, habitat maps provide critical information about the extent, health and composition of marine resources, which is vital for communicating information about the distribution and abundance of species to resource managers, scientists and the public. Habitat maps also support an increasing number of landscape ecology studies, as well as the process of marine spatial planning, including the design and evaluation of marine protected areas (MPAs).


The objective of this ground validation (GV) effort, conducted by NOAA's Center for Coastal Monitoring and Assessment Biogeography Branch, in collaboration with multiple federal, state, territory, academic and private sector partners, was to acquire spatially-explicit information about the geomorphological structure, biological cover and live coral cover of the seafloor in the U.S. Caribbean. 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. Consequently, 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 will be incorporated into a fine-scale assessment of the status, abundance, and distribution of marine habitats in the U.S. Caribbean.

Process Steps

Process Step 1

CC ID: 599947

A first draft benthic habitat map was generated by delineating features on the seafloor with discrete acoustic signatures. During the creation of this first draft map, the cartographer placed discrete points on or lines intersecting features in the map that had unknown acoustic signatures. Points were also placed on features with known 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.

Process Step 2

CC ID: 599948

NOAA scientists explored these ground validation locations in situ using an ROV. The resulting positional, video and photographic information was processed and will be used to classify each distinct habitat polygon to create a map of the seafloor in the U.S. Caribbean.
