초록

해수 중 용존영양염은 지구온난화의 주요 원인인 대기 중 이산화탄소 조절에 관여하는 해양의 역할을 이해하기 위한 핵심변수이다. 우리나라에서는 한반도 주변 해역의 해양환경 변화를 지속적으로 감시하기 위해 국가기관의 정기적인 관측과 다양한 연구과제수행을 통해 용존영양염 자료가 수집되고 있다. 이들 자료의 활용도를 높이기 위해 각 기관들의 자료를 통합하는 관할 해역 해양정보 공동활용시스템(Jurisdictional Ocean Information Sharing System, JOISS)이 구축되었다. 본 연구에서는 JOISS 용존영양염 자료에 대해 한반도 주변해역의 용존영양염 지역 농도 범위와 용존영양염과 다른 해양학적인 특성 및 용존영양염 성분들간의 상호관계를 이용한 일차 품질관리를 수행 하였다. 지역 농도 범위와 일차품질관리를 통합한 품질관리 표식을 제공함으로써 자료의 신뢰도를 향상하여 JOISS 용존영양염 자료의 활용도 증가에 기여하고자 하였다. 또한 JOISS 용존영양염 자료의 국제적인 상호비교성 향상에 필수적인 이차품질관리 방법을 제안하였다.

Dissolved nutrients in seawater are a key variable for understanding the role of the ocean in controlling atmospheric carbon dioxide, which is a major cause of global warming. In order to continuously monitor changes in the marine environment in the waters around the Korean Peninsula, dissolved nutrient data are being measured through regular observations by national institutions and various research projects. To increase the utilization of these data, the Jurisdictional Ocean Information Sharing System (JOISS), which integrates data from each institution, was established. In this study, for the dissolved nutrient data of JOISS, primary quality control was performed using the regional dissolved nutrient concentration range in the waters around the Korean Peninsula, and the correlation between the dissolved nutrient and other oceanographic characteristics or the correlation within dissolved nutrient components. Providing the quality control flags of regional range and primary quality control may increase the reliability of JOISS dissolved nutrient data and promote the utilization of dissolved nutrient data in JOISS. In addition, we proposed a secondary quality control method essential for improving the international comparability of JOISS dissolved nutrients.
