The SeaSonde is a compact, non-contact surface current and wave measurement HF radar system that can be deployed and maintained easily, and will perform even during extreme weather conditions such as hurricanes.

Designed and built by CODAR Ocean Sensors, the SeaSonde has a uniquely small antenna footprint and 360 degree possible viewing angle which minimizes site constraints and maximizes coverage area. SeaSonde can be remotely controlled and are ready due to its high data quality and reliability to be integral part of operational ocean observing networks. The SeaSonde is ideal for fine scale monitoring in relation with ports and small bays, as well as open ocean observation over larger distances up to 70 km. For extended coverage, the Long-Range SeaSonde can observe currents as far as 200 km offshore.

Some of SeaSonde benefits are shown below:

  • Search and rescue: “Probability of success is increased through the improvement in the estimation of search areas based on real time data and modelling”.





  • Marine protection: “Hindcast and nowcast analysis of surface currents help to identify land and sea origin of spills and organize operations efficiently. Combined with other data sources and technologies (meteorology, satellite) and air and sea surveillance it helps to organise response in case of emergency or accident. Current data can be assimilated in all kind of forecast models”.
  • Safe navigation: “HF Radar delivers data which are important for the development of crisis management studies and procedures. Decision support tools based on modelling and real time data can help to take objective decisions in crisis situation”.
  • Coastal engineering, fisheries and beach management:“Coastal studies related to sediment transport, bloom events and water quality need surface current monitoring in order to improve the understanding of natural processes and take management decisions”.
  • Marine sciences: “HF RADAR HF not only delivers current data but also wave parameters (significant wave height, period and direction). These data are integrated into long time databases which are available for multidisciplinary studies”.
  • Tsunami early warning: “HF Radar is an integral part of Tsunami Early Warning Systems as a complement of seismographic information and DART buoys. Its contribution consists in the reliable identification of the Tsunami wave 100 km away from the coast based on its characteristic orbital velocity pattern.”
