The tags are UHF/GPS tags that relay locations in real time to shore stations, and UHF/TDR tags that relay depth data in real time to shore stations.
It is also proposed to use Vemco pingers on the seals which can be tracked by the PAM equipment on the turbine support structure. These pingers operate at a frequency of 180kHz, with one ping per second and a battery life of 131 days.
This telemetry data should help inform how seals use the project area and therefore there sensitivity to collision or displacement from tidal turbine arrays.
