본 논문에서는 무선센서네트워크 기반의 연안·해양 환경모니터링 시스템을 이용해 연안·해양지역의 대기환경 정보는 물론 수질 환경의 정보를 측정하여 모니터링하였다. 연안 및 해양 환경의 모니터링을 위해 고려된 해양 센서를 사용하여 무선 센서 네트워크를 이용하여 온도, 습도, 조도, 기압, 이슬점의 대기환경 정보와 용존산소량(DO), 수소이온지수(pH), 수온 등의 수질환경 정보를 측정한 후 측정된 환경 정보를 베이스스테이션으로 전송하고 모니터링 하도록 하였다. 환경 정보를 전송할 때 정확하고 신속한 전송을 위하여 데이터 전달 확률이 높은 여러 라우팅 프로토콜 전송방식을 이용하여 전달하였다.

The analysis of ocean environment offers us essential information for ocean exploration. But ocean environment has a lot of environmental variables such as the movements of nodes by an ocean current, corrosion by salt water, attenuation of radio wave, occurrences of multi-path and difficulty of sensor nodes' deployment. It is accordingly difficult and complex to gather and process the environmental information through ocean data communication due to these constraints of ocean environment unlike the terrestrial wireless networks. To overcome these problems, we organized ocean communication network for monitoring underwater environment by real experiment in Gyeongpoho similar to ocean environment. Therefore, this paper aims at overcoming major obstacles in ocean environment, effectively deploying sensor nodes for ocean environment monitoring and defining an efficient structure suitable for communication environment by the implementation of ocean environment monitoring system in Gyeongpoho.

The West Sea Fisheries Research Institute of National Fisheries Research and Development Institute which is in charge of research on marine environment, fisheries resources and aquaculture carries out various monitoring projects with an aim of marine ecosystem conservation. The monitoring projects include costal oceanographic observation, serial oceanographic observation, fishing ground monitoring, national marine environmental monitoring, harmful algal bloom monitoring, Korea-China joint monitoring on the Yellow Sea and jellyfish monitoring. The monitoring produces basic data on fishing ground locations of main fishery species to improve fishery productivity. The data are also used to estimate variations in fisheries resources caused by climate change and to set up the policy for creating economic value from fishery, marine environmental conservation and marine leisure activities and conserving/controlling the marine environment for the sustainable production in the fishing ground.

Post-spill monitoring of hazardous noxious substances accidents is essential in the event of a spillage of significant quantities of pollutants and for the management of the marine environment resulting from the long-term effects of the persistent toxic substances. The accidental introduction of a sinker into the marine environment can create harmful anaerobic conditions in the benthic ecosystem and spread over the seafloor by the topography and currents. Through case studies, most post-spill monitoring includes modeling, remote sensing, and chemical analyses of the sediment and benthic organisms. The monitoring also evaluates the effectiveness of restoration and recovery activities and assesses damages and compensation.

The convergence of IT technology and marine facilities monitoring system is needed for effective monitoring systems to marine facilities. Especially the spread of smart device such as smart phone, smart pad, smart TV provide an environment that can check the status of the marine facility for marin facilities manager. However, smart phones and smart pads are used in a variety of OS used. Thus the monitoring system of the various service environments is difficult. In addition, There is inconvenience that must individually developed monitoring system for each device. In order to solve this problem NMMS (N-Screen Marine-facility Monitoring System) is proposed. NMMS is consist of Real-time monitoring system, Fault diagnosis system, Data storage system. To improve variety of smart devices accessibility, we use HTML 5. Through NMMS, marine facilities manager can use smart device such as PC, Notebook, smart phone, smart pad for marine facilities monitoring.

Recently, the marine monitoring technology is actively being studied since the sea is a rich repository of natural resources that is taken notice in the world. In particular, the marine environment data should be collected continuously in order to understand and analyze the marine environment, however the study of automatic monitoring of marine environment in Korea is not enough. In this paper, we proposed the marine environment monitoring system based on open source. The proposed system can be designed as a scale out system using Hadoop based time series database which it can easily process the increasing collection data by a scale out computer resources. It can also be used to analyze marine data by visualizing collected data.

해양환경에 관한 정보는 효율적인 연안 해역 관리를 위해 필수적이며, 해양환경요소에 대한 분석을 위해 현장 실측자료뿐 아니라 과거자료, 현재자료, 예측자료 등이 요구된다. 또한 연안환경 관리자뿐 아니라 해상관련 종사자, 어민 등이 해양환경 정보에 빠르게 쉽게 접근할 있는 기반이 마련되어야 한다. 최근에는 물에 관련된 정보를 효율적으로 관리하고 제공해야 하는 필요성이 증가함에 따라 물정보학(Hydroinformatics)이 크게 관심을 받고 있으며, 학술지 발간 및 학술회의 개최 등을 통해 이에 관한 연구가 활발히 진행되고 있으나 연안환경에 대한 연구는 미흡한 실정이다. 체계적인 연안환경 분석을 위해서는 방대한 시공간 자료가 필요할 것으로 예상되며, 지속적인 모니터링을 위한 통합시스템이 요구되므로 다양한 관측방법 적용될 필요가 있다. 본 연구에서는 인공위성을 활용하여 연안환경 변화를 모니터링 할 수 있는 방안을 제안하기 위해 국외의 연구사례들을 분석하고, 우리나라 연안환경에 적합한 위성을 조사함으로써 연안환경 분석과 관련하여 관측 가능한 인자들을 파악하고자 한다. 이를 통해 연안환경 모니터링을 보다 체계적으로 수행하기 위한 인공위성 기법의 특징들을 이해하는 것이 본 연구의 목적이다. 향후 서해안지역의 연안 환경 변화 탐지를 위한 알고리즘을 구축하여 한반도 연안환경분석을 위한 인공위성의 유용성을 검증할 계획이다.

An integrated real-time monitoring software for coastal environment has been developed by using GUI. The system consists of modeling module, real-time monitoring module, and post-processing module of the modeling and monitoring results. The system was applied to a port construction site. The main purpose for the system is to setup the information system that user can obtain the environmental information easily and quickly. The system can be used to monitor environmental changes due to construction activities in coastal waters and to assess environmental impacts accurately in real-time. In conclusion, the system will be a good tool for finding out countermeasures to lessen water pollution and clean seawater.
