While oxygen loss in oceans has been documented, the changes in dissolved oxygen concentrations in lakes are less well understood, in part owing to a lack of long-term and large-scale studies, ...

In the early 1990s, 73 percent of the studied lakes registered average summer dissolved oxygen levels above 5 mg/l. By 2021, 55 percent of the lakes exceeded the oxygen threshold.

Warming climate spurs harmful oxygen loss in lakes Date: December 6, 2022 Source: Cornell University Summary: New research shows a continually warming world is leading to extended, late-summer ...

On several expeditions, the team’s dissolved oxygen sensors oddly suggested that the substance, rather than just being consumed by organisms, was actually, on the whole, being produced.
