As challenges arise in the form of natural disasters and in spite of infrequent occurrence of Tsunamis in the Indian Ocean, which could occur anytime and could be very devastating. OOS team has developed, tested and have established Tsunami Buoy system with Bottom Pressure Recorder (BPR) in Indian Seas.
The Tsunami buoy systems consist of two units, a surface buoy and the Bottom Pressure Recorder (BPR). Communication between BPR and the surface buoy is established through acoustic modems and surface buoys uses satellite to communicate the recorded values to shore station.
During normal condition, the BPR measures the pressure every 15 seconds and communicates it to the surface buoy every hour with four 15 minute averaged water level values. The surface buoy in turn transmits the data to the shore station.
In the event of a Tsunami, the BPR measures the pressure and communicates it to the surface buoy every 5 minutes with ten 30 second water level values. The surface buoy transmits the data to the shore station every 5 minutes for 3 hours. |
