Carbon and Nitrogen Turnover Processes Limit Dissolved Oxygen in Rivers: Beyond Temperature and Salinity

Factors such as water temperature and salinity are usually important in determining the solubility of dissolved oxygen and play a significant role in the occurrence of low oxygen levels. In addition to these factors, research has shown that the turnover processes of carbon and nitrogen in rivers are highly coupled with oxygen consumption, making them important limiting factors in the depletion of dissolved oxygen in rivers.
