HF radar system in the Gulf of Trieste (GOT)


HF radar systems measure the speed and direction of surface and ocean currents in near real time (displayed in UTC with an additional delay of up to 1 hour). Ocean currents are the equivalent of winds in the atmosphere in that they move things from one place to another. These currents carry pollution with them and it is therefore important to understand currents from both an environmental and economic perspective. Currents transport navigable objects, so this information is used by rescuers to make decisions during search and rescue operations at sea.


HF radars can measure currents over large sea or ocean areas and are therefore deployed at high altitude locations along the coast. The complete HF radar system in the Gulf of Trieste includes, in addition to the radar over Izola, radars at 3 locations along the Gulf: over Piran (Slovenia) and off Trieste and Aurisina (Italy). The results of the measurements from all 4 radars are combined into a single vector representation of the currents in the Gulf of Trieste. Finally, the results of the measurements are an excellent check on the model predictions that can be fed from them.


In June 2022, after several years of effort, the National Institute of Biology, Marine Biological Station (MBP) installed a second radar system of this type in the parking lot on the slope below the Izola Hospital, with co-funding from the international INTERREG MED project SHAREMED.
