Marine biogeography is the study of marine species, the geographic distribution of their habitats, and the relationships between living organisms and the environment. By mapping benthic habitats, studying what occurs on the bottom of a body of water, and assessing the relationships between the environment and the organisms that live there, biogeographers provide useful information to protect and conserve marine resources.

Marine biogeographers often use Geographic Information Systems, or GIS, to aid in their research of marine animals, plants, and habitats. Scientists and GIS specialists develop map-based data that describe the distribution and ecology of living marine resources and their connections to human communities. State and federal planners can apply these tools and information to position aquaculture sites and alternative energy facilities, and to protect fisheries and coral spawning areas. Information from biogeographers allows planners to consider possible scenarios, such as new development, that may, or may not, impact the environment.
