This study aims to assess the effect of the turbidity, seasons, and dissolved oxygen (DO) on chlorophyll-a (Chl.a) level and ultimately as a major triggering factor for events damaging the marine ecosystem, such as harmful algal bloom, red tide, and fish kills in the State of Kuwait. Different variables, such as sea temperature, salinity, pH, Chl.a concentration, electrical conductivity, turbidity, and DO, were used to monitor physicochemical water quality parameters in 2017. The used data referred to 15 floating monitoring stations in Kuwait’s territorial waters. The data were analyzed using descriptive statistics, time series analysis, and inverse distance weighted (IDW) spatial model. The interaction of those parameters with each other, with various biological entities, and more, plays a significant role in determining marine ecosystem health and thus productivity. The results from this study revealed that turbidity is a main – and controlling – factor affecting Chl.a levels. Seasonality and DO concentrations also played key roles in exerting stress on the local marine ecosystem. The successive events observed in 2017 – the fish kill, then the red tide, and the decline in DO – suggest the urgent need for an extensive monitoring program in the north-western Arabian Gulf which focuses chiefly on eutrophication and nutrient elements. This study gives an integrated and comprehensive view of the investigated physicochemical variables in the territorial waters of the State of Kuwait; they can in turn be relied upon as a water quality indicator in the wider north-western Arabian Gulf. Data generated in this study will assist in future understanding, prediction, and forecasting of major environmental incidents like harmful algal blooms, red tides, and fish kills.

本研究旨在评估浊度、季节和溶解氧 (DO) 对叶绿素a (Chl. a ) 水平的影响，并最终将其作为破坏海洋生态系统的事件的主要触发因素，例如有害藻华、红色在科威特国潮汐和鱼类死亡。不同的变量，如海水温度、盐度、pH 值、叶绿素。一个2017年采用浓度、电导率、浊度和溶解氧监测物化水质参数。所用数据参考科威特领海15个浮动监测站。使用描述性统计、时间序列分析和反距离加权 (IDW) 空间模型分析数据。这些参数相互之间、与各种生物实体等的相互作用在决定海洋生态系统的健康和生产力方面发挥着重要作用。这项研究的结果表明，浊度是影响叶绿素的主要和控制因素。一个水平。季节性和 DO 浓度在对当地海洋生态系统施加压力方面也发挥了关键作用。2017 年观察到的连续事件——鱼类死亡、赤潮和溶解氧下降——表明迫切需要在阿拉伯湾西北部开展广泛的监测计划，主要关注富营养化和营养元素。这项研究对科威特国领海中所调查的物理化学变量进行了综合和全面的了解；反过来，它们可以作为更广泛的阿拉伯湾西北部的水质指标。本研究产生的数据将有助于未来了解、预测和预测重大环境事件，如有害藻华、赤潮和鱼类死亡。
