The coastal waters of Jeju Island, Korea, experience recurrent macroalgal blooms, particularly green tides, driven by nutrient enrichment and anthropogenic activities. The semi-enclosed bays of Jeju Island-Jocheon, Gimnyeong, and Sinyang-are especially vulnerable to eutrophication due to prolonged water residence times and accumulation of terrestrial pollutants. We provide a time-series dataset of monthly measurements of environmental parameters and greenhouse gas concentrations collected from March to November 2020 at 12 stations across the three bays. Surface seawater temperature, salinity, and dissolved oxygen were measured in situ using a calibrated portable multi-parameter probe. Additionally, discrete seawater samples were collected using a 10 L Niskin sampler for biogeochemical parameters (nutrients, pH, total alkalinity) and greenhouse gas concentrations (CO, CH, and NO). This dataset provides insights into the spatiotemporal dynamics of physical-biogeochemical properties and greenhouse gas concentrations associated with green tides, and serves as a valuable resource for understanding how coastal ecosystems respond to environmental changes.
韩国济州岛沿海水域经常出现大型海藻爆发，尤其是绿潮，这是由营养物质富集和人为活动导致的。济州岛的半封闭海湾——朝天、金宁和新阳——由于水停留时间延长和陆地污染物积累，特别容易受到富营养化的影响。我们提供了一个时间序列数据集，该数据集包含2020年3月至11月在这三个海湾的12个站点每月测量的环境参数和温室气体浓度。使用校准后的便携式多参数探头现场测量表层海水温度、盐度和溶解氧。此外，使用10升尼斯金采水器采集离散海水样本，用于分析生物地球化学参数（营养物质、pH值、总碱度）和温室气体浓度（一氧化碳、甲烷和一氧化二氮）。该数据集提供了与绿潮相关的物理-生物地球化学性质和温室气体浓度的时空动态见解，并作为了解沿海生态系统如何应对环境变化的宝贵资源。
