Ⅳ. Results
1. Observation system design and producing

Submarine Cables acoustic measures the ambient noise by installing off the coast within 1km and was designed as a moving structure as needed. Accordingly, installation and recovery is possible, at the same time with a flexible structure, to allow normal operation even when buried, and corresponding to the subsea environment has been designed and manufactured with sea water-proof, pressure-proof and water-proof. Submarine acoustic signals received from the 21 channels of the sound cable is passed to the acoustic signal reception system via an optical cable is converted to an optical signal in the connection housing. Wave / temperature sensor cable is designed as a moveable structure to measure wave height and water temperature in real time by installing the coast within 1Km. This installation and recovery is having each sensor module and the cables are detachable structure, during normal operation allowing to be laid water-based, water pressure castle was built in response to the undersea environment with my tightness.
Utilizing as the conventional RADAR and AIS, was configuring the database, and operating in conjunction with a module unit is possible, through the storage vessel and the tracked information track between the respective data in the database module is integrated operation of each module. Pulling the data from the same point in time using the database tracks the location of RADAR, the vessel utilizing the AIS, as it is possible to determine the temporal and spatial information of the ship by using a database.
For existing ocean observation buoys, internal orientation sensor, buoy position monitor(watch-dog) and the Iridium satellite communication module that location data can be transmitted was installed. Separately, an ultrasonic current meter(ADCP) to observe the marine physical environment, meteorological sensors, wave observation sensor, CTD, chlorophyll sensors were installed.

2. Observation system test on the exhibition site

In national jurisdiction waters, for the purpose of building real-time monitoring observation system for the marine environment and the detection of moving objects in the water, we decided the East Sea Research Center, Uljin Gyeongbuk as a pilot area and carried out on-site observations using subsea acoustic cable, wave height/temperature sensor cable, radar/AIS, various equipment and programs. Through the subsea acoustic cable, the direction of the moving object on the surface and the underwater was detected and confirmed the vessel route using the radar & AIS. Through the wave/temperature sensor cable and the LiDAR, we compared the movement patterns in real time and a sensor cable was tested. Using data obtained from the wave sensor cable, we developed a real-time wave reproduction algorithm. Since wave sensor is spatially apart by tens of meters, in order to extract the wave therebetween, by taking the weighted average of the two sensors, we extrapolated the time-series signal of 1m distance. We obtained the same effect as sensors are arranged in a spatially 1m interval.

3. National jurisdiction real-time marine environment Observation system operation

We were upgraded to a prototype of year 1 and 2, improved mechanical strength and tightness of the prototype and the UI of the real-time visualization program. On 16 to 23 June 2014, with the concept of the real sea installation, field trials were carried out important national jurisdiction in the coast of Ulleungdo. Utilizing Ulleungdo-Dokdo Ocean Science Station, we were installed on-site command center to take advantage of the resource base of power. Before installation acoustic undersea cable topographic survey was conducted, it was based on a subsea cable installation, were the seafloor state underwater photography for cable management, cable management techniques were studied mosaics through. Using seabed acoustic cables and radar & AIS, we detected a moving object on the surface. Through LOFAR analysis, we identified to be a moving object surface characteristic, and the noise emission of the moving object obtained through line array sensor was identify the movement direction using the beam-forming technique. Among the jurisdiction area, Haeundae beach is an area that beach erosion due to wave and rip currents are formed. For the actual application of the observed sea cables, wave observations carried out in the area, Haeundae Busan, to be significant to measure wave height September 16, 2014 to 18. At Haeundae beach, through the installation and operation of the wave/temperature cable, wave gauge and ADCP, we completed the verification of real-time observation system implementation
