Oceanographic radar plays a key role in making Canada’s west coast safer for shipping navigation, incident response (such as search and rescue and hazard spill), and tsunami detection. Land-based oceanographic radar measures and maps surface ocean currents, and, for some systems, measures wave heights. A major benefit of oceanographic radar is their ability to operate under any weather conditions, day or night.
CODAR (Coastal ocean dynamics applications radar) or coastal radar is a technology that permits the remote measurement of surface currents in the ocean. ONC currently operates a total of eleven CODAR stations: four in the Strait of Georgia, two in the Strait of Juan de Fuca, four in the Prince Rupert/Hecate Strait region, and one in Nova Scotia. These stations generate sea surface current maps once per hour, available via Oceans 3.0.

WERA radar is a high-frequency, long distance (more than 200 km) oceanographic radar. These systems are capable of detecting large events like storm surges and tsunamis up to 80 kilometres from shore. They can provide a complete data set within less than 10 minutes, providing critical warning time in the event of a storm or natural disaster.
