Analysis of Marine Mammal Biologically Important Areas and Species Density on the East Coast
In accordance with various federal regulations, any agency or organization planning to conduct activities in the marine environment that may harm marine mammals must undergo an impact assessment process. Two available tools to assist resource managers in these analyses include biologically important...
