Project Title: Predictive Modeling of the Distribution of Deep-Sea Corals in the Main Hawaiian Islands
Goal or Purpose

To develop a model to predict likely locations of high densities of two species of deep-sea corals using maps of existing observations of the species of interest, areas of hard seafloor, high resolution bathymetry, and high current velocities.

Anticipated Management Application(s)

Model results will enable scientists to be more refined in their search for likely locations of deep-sea coral beds. Results can also be used for preliminary planning of subsea communications and power cable routes.

Project Results and Management Outcomes

Records of the presence and relative abundance of pink coral (Corallium secundum) and gold coral (Gerardia sp.) have been developed. Grids of the maximum current velocity have also been developed using output from two different models, tuned with data on current velocity changes with depth. A high resolution (10 m) grid of seafloor depths of the model area has also been obtained, and modeling efforts are underway.
