Ecological Decision Support – Fisheries

Convergent

Like Upwelling

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.

Water Quality – Nearshore Currents

Alongshore Current

Nearshore currents derived from single site radial currents track the movement of water quality constituents within 3 km of the beach.

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
