Analysis of Water Temperature and Dissolved Oxygen

Dissolved Oxygen (DO) and Water Temperature (T) are two essential parameters in assessing water quality because of their significant role in aquatic life and habitats. DO is a measure of the amount of oxygen available for aquatic organisms to breath and survive. The concentration of DO depends on several factors such as temperature, pressure, and salinity (Wetzel, 2001). In the Logan River, Utah, the temperature has the most influence on DO. The aim of this study is to assess the relationship between DO and T at one of the sites of the Logan River Observatory named “Logan River at Main Street (Highway 89/91) Bridge” in a reproducible way. At the end, meeting the required quality standards by them is also investigated.溶解氧（Dissolved Oxygen, DO）与水温（Water Temperature, T）是水质评估的两项核心参数，二者在水生生物与栖息地生态系统中发挥着至关重要的作用。溶解氧是衡量可供水生生物呼吸、维持生存的氧气含量的指标。其浓度受温度、气压、盐度等多种因素影响（Wetzel, 2001）。在犹他州洛根河流域，水温对溶解氧的影响最为显著。本研究旨在以可复现的方式，探究洛根河观测站一处命名为"Main Street（89/91号公路）大桥段洛根河"的监测点位处溶解氧与水温之间的关联。最后，本研究还将调查这两项参数是否符合既定的质量标准。
