چکیده
Dissolved oxygen (DO) is an important parameter for evaluating the seawater quality of oce-anic environment, but distribution DO and its possible mechanisms marine environ-mental regulation are less studied. Here, spatial influence main environmental factors on were explored using in-situ observation data collected in northern coastal waters Beibu Gulf April 2021, based cluster analysis, partial correla-tion multiple linear regression. The results showed that surface water study area gradually increased from nearshore to offshore, with nearshore’s being nearly saturated offshore supersaturated. Tieshan Port Maowei Sea had lowest degree saturation. correlation analysis between concentration revealed was mainly influenced by temperature salinity as well other biochemical (i.e., chlorophyll-a, turbidity, pH). Significant differences existed dominant various parts Gulf. western river (Beilun River, Fangcheng Maoling Qinjiang River) estuaries areas dominated photosynthesis, while eastern (Fengfeng Nanliu oxidation-decomposition. In addition, also affected mangrove ecosystem, aquaculture, industry.
