Title:
NOAA Point Shapefile - ROV transects, US Caribbean - St. Croix and Southwestern Puerto Rico - Project NF-06-03, S-I911-NF-06 - (2006), NAD83
Abstract:
This shapefile denotes the location of underwater photos and/or video that were collected by NOAA scientists using a SeaEye Falcon ROV (remotely operated vehicle). Photos and/or video were collected between 03/21/2006 and 04/02/2006 along 7 transects north of St. Croix and along 11 transects in southwestern 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 manag ers, 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).

Why was the data set created?

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 statu s, abundance, and distribution of marine habitats in the U.S. Caribbean.
