What is a Benthic Survey? Why is it needed?

A Benthic survey is an assessment of the submerged aquatic resources present in a particular area, such as coral, seagrasses, and sponges. It is usually conducted by a biologist who takes pictures, videos, and observations of the area. Benthic surveys are required by regulatory agencies such as the Army Corps or the Florida Keys National Marine Sanctuary to ensure that any construction or development projects in the area do not adversely affect these resources.

The survey must be performed by a biologist who is approved by the Florida Keys National Marine Sanctuary and has a special permit to conduct Benthic surveys. If any of the resources are found to be present in the project footprint, the project may need to be modified, or mitigation may be required. This can include moving the project out of the way or relocating the coral or other resources.

Overall, Benthic surveys are a critical component of protecting the submerged aquatic resources in sensitive areas. While they may seem like an added expense or delay in the project process, they are necessary to ensure that development does not harm these valuable resources. So, if you’re planning a construction or development project in an environmentally sensitive area, be prepared for the possibility of a Benthic survey.
