서남해 해상풍력 실증단지 해역을 중심으로 구축된 모니터링 자료를 분석하여 해양물리, 해양수질, 해저퇴적물의 환경 특성을 파악하고 현황을 제시하였다. 파고와 부유사 농도, 유속과 부유사 농도의 상관관계를 분석하여 연구 해역 토사의 부유 특성을 고찰하였다. 춘계 시(1 개월) 파고와 부유사 농도 사이에는 상관계수 0.61~0.69의 상관성을 보였으며, 1 m 이상의 높은 파고가 발생하면 75 mg/L 이상의 부유사 농도가 관측되었다. 수질평가지수 산정 시 필요한 항목을 중심으로 수질 현황을 분석하였으며 대부분의 정점에서 1등급(매우 좋음)을 보이고 있었다. 클로로필-a의 변동폭이 다른 항목에 비해 상대적으로 높게 나타나 수질평가지수에 영향을 주는 중요 인자로 파악되었다. 해저퇴적물 내 중금속 현황은 모든 항목의 평균값이 해양환경 주의기준 이하로 검출되었으며 강열감량과 입도분포는 높은 연관성을 보였다.
Abstract
This study aims to present the characteristics of marine physics, water quality, and sediment quality around offshore wind farm near the Gochang and Buan sea areas through the analysis of monitoring data. The relationships between suspended solid and wave height as well as suspended solid and flow velocity were analyzed. We found that Correlation Coefficient values of 0.61~0.69 between wave height and suspended solid, and suspended solid concentration reaches 75 mg/L or higher when wave height of more than 1m occurred in the spring (1 month). The water quality index (WQI) was used to identify the status of the water quality in the study area. Most of the measured points were rated first grade (very good). The variation of chlorophyll-a was relatively hight compared to the other criteria, indicating that it is a major factor affecting the quality index. In the sediment column, all heavy metals were detected below the Threshold Effects Level(TEL), and ignition loss and grain size show a positive correlation.
