8 Universities in MARACOOS contribute to HF Radar Network
Our Approach: Develop statistical models using bottom trawl surveys and MARACOOS 3-D data to predict species distribution based on observed or forecasted MARACOOS 3-D fields.

Conclusions• Mid Atlantic Long Range HF
Radar Network is celebrating its 10th anniversary
• MARCOOS is delivering Quality Controlled Surface Current Data and Forecasts to the US Coast Guard for improved SAR
• HF Radar Network is helping to describe the nature of the flow in the Mid Atlantic
• We are also developing the dual-use capability of the radar for vessel detection
