The Monitoring and Early Warning System in Case of Exceptional Events, produced by natural hazards in the Black Sea, consists of the following:
-
3 autonomous marine monitoring stations, composed of:
Surface beacon:
- solar recharging system for accumulator batteries;
- power supply management system of the station;
- switchable satellite / radio communication system;
- data acquirer with integrated management;
- remote control system and two-way real-time radio / satellite communication;
-
weather sensor system;
-
active and passive radar system;
-
optical signaling system;
-
acoustic system for managing the communication and transmission of data with the installed underwater equipment;
Multiparameter probe fixed at 5 m depth, comprising:
-
Doppler sensor for current;
-
conductivity sensor;
-
temperature sensor;
-
pressure sensor;
-
oxygen sensor;
-
turbidity sensor;
-
chlorophyll sensor;
Multi-parameter probe fixed to the seabed with bidirectional acoustic communication modem with surface beacon, with autonomy of approximately 2 years and with remote triggering system:
-
Doppler sensor for current;
-
conductivity sensor;
-
temperature sensor;
-
pressure sensor;
-
battery system for powering the sensors with a duration of approx. 1 year;
Tsunameter - mounted on the seabed, near the beacon;
-
own anchoring system;
-
tsunameter positioned on the seabed with bidirectional acoustic modem of communication with surface beacon, with autonomy of approximately 2 years and with remote triggering system;
-
battery system for powering the sensors with a duration of approx. 2 years The three complex beacons called EuxRO 1, EuxRO 2 and EuxRO 3, are located on the Romanian continental shelf, in the territorial waters of Romania, at a distance of approximately 160 km from the coast. Their location was approved by the Ministry of National Defense, through the General Staff of the Naval Forces, represented by the Maritime Hydrographic Directorate (DHM). The transmission of the data collected from the installed sensor systems is done acoustically, in real time. These data are transmitted to the surface beacon, then satellite, in real time, to the National Monitoring and Alarm Center for Marine Natural Hazards EUXINUS, in Constanța.
The Meda Type Coastal Station, located near the port of Mangalia, but also of the Romanian-Bulgarian border, at a water depth of 15 m, is equipped with:
• Meteorological station, with sensors for pressure, temperature, humidity, wind direction and speed;
• Multiparameter probe fixed at 5m depth;
- Doppler sensor for current;
- conductivity sensor;
- temperature sensor;
- pressure sensor;
- oxygen sensor;
- turbidity sensor;
- chlorophyll sensor;
• ADCP for measuring:
- the statistical directional spectrum that allows the calculation of the main parameters of the waves (The instrument processes the data on waves, every 10-20 minutes):
- Hmo (Significant amplitude);
- Hmax (Maximum amplitude);
- Tm (Average period);
- Tp (Peak Period);
- Dm (Average direction of waves);
- Dp (Top Direction) Data transmission is performed in real time using the mobile network.
The Coordination Center for Receiving, Processing Data and Presenting Information, operates continuously (24h / 7 days) and ensures the automatic operation of detection and monitoring stations, collection and real-time processing of data transmitted by equipment installed in the system and transmission of alarm notifications in the event of a dangerous event. It is equipped with hardware, communication systems and specialized software applications. Specialized Software Systems (Tsunami Analysis Tool, Probabilistic and Evolutionary Early Warning SysTem, GEM 2.1) for assessing the consequences of marine geohazards provide the following functions: - interconnection of marine seismic data networks in Romania and Bulgaria; - automatic operation of tsunami detection stations; - receiving and storing in real time the monitoring data provided by the installed equipment, but also the data on seismic events provided by other monitoring sources; - development of scenarios for the generation and propagation of tsunami waves, and estimation of floodable coastal areas; - generation of maps in standard GIS format.
