Research Brief: How Global Warming Impacts Metalimnetic Dissolved Oxygen
Sam Norton
Global warming is well known to prolong stratification, leading to lower concentrations of dissolved oxygen in the hypolimnion and higher concentrations in the epilimnion.
However, few studies have investigated how DO changes within the metalimnion, especially the cause and effect of a metalimnetic oxygen minimum (MOM).1
A 2025 study published in Scientific Reports simulated global warming’s impact on a reservoir in order to observe how DO responds to warming throughout stratification...
