Species Distribution Modelling and Kernel Density Analysis of Benthic Ecologically and Biologically Significant Areas (EBSAs) and Other Benthic Fauna in the Maritimes Region
We present input data and output maps for random forest species distribution models and kernel density estimation (KDE)-derived significant areas for benthic Ecologically and Biologically Significant Areas (EBSAs) and other benthic taxa in Fisheries and Oceans Canada’s Maritimes Region: Horse Mussel...
