In Narragansett Bay, light attenuation by total suspended sediments (TSS), colored dissolved organic matter (CDOM), and phytoplankton chlorophyll-a (chl-a) pigment is 129, 97, and 70%, respectively, of that by pure seawater. Spatial distribution of light attenuation indicates higher values in the upper Bay, where rivers with sediment and nutrient-rich waters enter and elevate TSS, CDOM, and chl-a concentrations. The temporal trends of light attenuation during the summer months (July–August) differed at various locations in the Bay, having the highest values in July. For the same period, spectral methods overestimated attenuation throughout the Bay. These findings quantify the behavior of light attenuation in space and time, providing information that can guide decisions related to improving water clarity and help understanding the effects of various environmental and management scenarios on it.

量化对河口和沿海隔离带中的光衰减的贡献：应用于罗得岛纳拉甘西特湾。

在纳拉甘西特湾，总悬浮沉积物（TSS），有色溶解有机物（CDOM）和浮游植物叶绿素-a（chl-a）色素的光衰减分别是纯海水的129％，97％和70％。光衰减的空间分布表明上海湾的值较高，那里有沉积物和营养丰富的水的河流进入并升高了TSS，CDOM和chl-a的浓度。夏季月份（7月至8月）光衰减的时间趋势在海湾的不同位置有所不同，7月份的值最高。在同一时期，频谱方法高估了整个海湾的衰减。这些发现量化了光衰减在时空上的行为，
