Exact and rapid acquirement of ocean environment information is going to become more of an indispensable source of naval operations. Ocean surface measurements using High Frequency (HF) radar, which covers about 10-220km and has spatial resolution of 0.3-12km, have being operated in our country. It remotely observe and transmit realtime sea surface currents and waves. In the near future, the HF radar systems will be established along the whole coastal area. A performance of network of HF radar will support various marine and naval activities. Operational uses of HF radar for enhancing naval operation ability are suggested.

Real-time oceanographic information system was developed using platforms of aquaculture farms to examine causes of mass mortality of hatchery fishes, and to reduce the damage of mass mortality which has been occurred frequently off coast by abnormal change of ocean conditions. The system had the advantages of direct data distribution to fishermen at the farm and instant maintenance of equipments due to easy access to the farms and residents at the farms in comparison with offshore mooring buoy system. To avoid discontinued measurement of the system, repairs caused by malfunction of equipments, bimonthly preventive maintenances and daily monitoring of measured data were systematized. Confidence intervals calculated by a statistical method using accumulated data were applied to data management. Such activities could minimize discontinuance of measurement and keep information more trustful. In addition, the system has various ways of data distribution. Through homepage and e-mail in the internet, information was provided to public. Display units which were connected to equipments at the farm gave the measured data directly to fishermen, which guided them to run their farm scientifically. Finally large display unit was installed at a fish market and showed the measured data at the nearest station with tide and weather information. Proper region for aquaculture and wintering region were studied using temperature data obtained by the system in 2006. The system will contribute to reduce economic damage of coastal fishery and to understand coastal marine environment.

소형선박인 어선·낚시어선의 전복 사고로 인한 인명 사고가 지속적으로 발생 되어지고 있다. 소형선박인 어선·낚시어선의 운항 시 선박의 운항자가 선박의 실시간 복원성 상태 인지 없이 어업 또는 낚시 활동하는 동안 해양 환경 상태 또는 적화 상태 변화와 추가적인 외력에 의해서 선박의 전복 사고가 발생 되어진다. 본 연구에서는 소형선박 어선·낚시어선의 실시간 복원성 감시를 위한 안전키트의 실험적 검증을 실시했다. 안전키트의 자이로센서를 활용하여 실시간 횡요각 데이터 측정 및 주파수 분석하여 횡요주기를 도출하고 횡메타센터(GM)을 도출한다. 또한, 실사간 도출된 GM에 따라 국제해사기구(IMO, International Maritime Organization) 비손상 복원성 평가 기준 값을 추정한다. 실험적 검증을 통하여 개발된 소형선박 어선·낚시어선용 안전키트의 정확도 확인 및 개선점을 발견하였으며, 향후 연구 계획에 대해서 제시했다.

For effective conservation of the oceans and harbors, long-term and systematic development of the ocean and harbor monitoring system is essential. A monitoring system capable of real-time and accurate data acquisition is necessary for dealing with the level of contamination by situations, such as red tide and foods. This paper introduces an effective and economical real-time harbor environmental monitoring system that utilizes PCS wireless data communication technology. The monitoring system has various functions, such as multiple communication, TCP/IP protocol for wireless internet access, system time synchronization, and bi-directional communication between the measuring device and the server. The system has been implemented at Shinseondae harbor pier in Busan to validate the system's stability and effectiveness in data acquisition. The acquired real-time ocean and harbor environmental data is expected to have a large effect, when shared with the public through the Internet.
