S. Lee, E. Lee, H.S. Yoo and M- J. Lee Journal of Coastal Research 2020 102/sp1 (pp 39-46) Center for Environmental Data Strategy, Korea Environment Institute, Sejong, South Korea Various development projects, including harbor construction, are carried out in coastal areas. In South Korea, the performance of environmental impact assessment (EIA) is legally required for development projects in marine areas to monitor the impacts of these projects on offshore marine environments. National Marine Environmental Measurement Network (NMEMN) data can be used to examine the overall status of the marine environment prior to a development project, but these data are very limited. In contrast, EIA data are collected from a large number of locations over various periods. The purpose of this study was to analyze trends in the coastal marine environment using NMEMN and EIA data collected in 2010-2011 for Busan New Port, where multiple development projects are underway. Use of the combined dataset enabled more effective analysis of trends in marine water quality, including those in dissolved oxygen, the chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP), than did the use of NMEMN data alone. Values increased in the bottom layer, especially in the summer, after port operation had begun. For example, average summer ranges for COD, TN, and TP in the bottom layer in 2000-2005 were 1.41-2.2 mg/L, 0-0 μg/L, and 0-17.62 μg/L, respectively, and those in 2006-2011 were 1.53-3.2 mg/L, 0-281 μg/L, and 8.09-49.35 μg/L, respectively. In the future, data from various sources should be integrated into EIAs to identify not only the impacts of a single project, but also the overall impacts of multiple changes in an area. This method also could be used to provide basic data for continuous management of the marine environment.

Lee Chines of Coderal Research 2020 102 / SP1（PP 39-46）韩国环境研究所，Sejong，Sejong，韩国各种开发项目，包括港口建设，在沿海地区进行。在韩国，环境影响评估（EIA）的表现在法律上是在海洋地区的发展项目中，以监测这些项目对海上海洋环境的影响。国家海洋环境测量网络（令人遗症）数据可用于在开发项目之前检查海洋环境的总体状态，但这些数据非常有限。相比之下，在各种时段中从大量地点收集EIA数据。本研究的目的是利用2010 - 2011年2010 - 2011年釜山新港口收集的丹姆姆和EIA数据分析了沿海海洋环境的趋势，其中多个开发项目正在进行中。使用组合数据集的使用更有效地分析了海洋水质的趋势，包括溶解氧，化学需氧量（COD），总氮（TN）和总磷（TP）的趋势分析，而不是使用Nmemon数据独自的。在港口运行开始后，底层中的值增加，特别是在夏季。例如，2000-2005中底层COD，TN和TP的平均夏季范围分别为1.41-2.2mg / L，0-0μg/ L和0-17.62μg/ l，以及2006年的-2011分别为1.53-3.2mg / L，0-281μg/ L和8.09-49.35μg/ L.将来，来自各种来源的数据应集成到EIAS中，以识别单个项目的影响，还要识别一个区域的多次变化的总体影响。该方法还可用于提供持续管理海洋环境的基本数据。
