Development of Spatially Referenced Data Layers for Use in the Identification and Delineation of Candidate Ecologically and Biologically Significant Areas in the Newfoundland and Labrador Shelves Bioregion
By Ollerhead, L.M.N., Gullage, M., Trip, N., and Wells, N.
Abstract
A series of spatially referenced data layers were developed in support of the work to identify and delineate candidate Ecologically and Biologically Significant Areas (EBSAs) in the Newfoundland and Labrador (NL) Shelves Bioregion north of the Placentia Bay Grand Banks Large Ocean Management Area (LOMA). The purpose of this report is to document the many and diverse datasets that were used to create the spatially referenced data layers for the analysis and to describe the tools and analytical techniques employed in this study. Numerous data management, statistical and spatial analysis software applications were used to process, analyze and display the data. Statistical and spatial analysis techniques were applied to the data to transform them for inclusion in the analysis. Additional data reduction techniques were applied to some of the larger datasets to reduce the number of variables and simplify their interpretation. The data used in this study characterized many biological components of the marine environment including corals, sponges, fishes, marine mammals and seabirds in addition to oceanographic and other environmental data.
