| Coastal Ocean Dynamics Applications Radar, or CODAR, is a land based HF Radar system used for measuring sea surface current. Measurements can be made at long range, across wide areas, using a single instrument. The Gulf of Maine CODAR stations (supported by NERACOOS) use Long-Range SeaSonde, an instrument anufactured by Codar Ocean Sensors. The photos above show a receiver antenna (left), a transmitter antenna (right) and an image of a current vector map produced from data collected at two CODAR stations (center). Click the center image to view the latest total vector plot. For more information on how CODAR data are collected and processed to make vector plots like the one shown above, click here |
| The map (right) displays the approximate locations of both existing and future University of Maine Gulf of Maine CODAR installations. The radial lines diverging from each each site denote the expected coverage area and range of each radar. When all sites are operational, hourly current vector maps will be produced for all regions where two or more sites coverage areas overlap. As of June 2005, three CODAR installations are in operation (Greens Island, Cape St. Mary, and Wood Island, shown in blue). |  |
