Two new products—the Ocean Dimensions animation and Crowded Ocean Spaces: A 3D View visualization—explain why two-dimensional marine maps cannot tell the whole story. Understanding this fact helps viewers gain a more accurate picture of marine-siting conflicts and compatibilities, including those related to offshore wind energy development. Traditional maps can give the false impression that the marine space is very crowded. In reality, marine uses are spread out among many dimensions: the sea surface, seafloor, water column, air column and even the dimension of time.
