Marine Life Models

Multiple providers

Overview

Included here are maps characterizing the predicted density, distribution, and abundance of marine mammals, birds, turtles, and the surveyed biomass of fish. (Population densities of marine mammals and sea turtles show the average number of animals present per square kilometer during a given month or season.) The data originate largely from shipboard observations and aerial surveys; models incorporate environmental factors whenever possible. Several map products are available that distill multiple layers into simplified maps and build a general understanding of the ecological richness or abundance in a particular area.
