Kind: research · Impact: medium

## In brief

- A freshwater reservoir showed rapidly stimulated oxic methane production.
- The stimulation was driven by a labile dissolved organic phosphorus pool rather than methylphosphonate hydrolysis.
- The study, published in Nature Water, points to an alternative mechanism for immediate oxic methane production in stratified freshwaters.

## Why it matters

Methane produced in oxygenated water is an important part of freshwater greenhouse gas budgets, so identifying a different driver than the methylphosphonate pathway matters for how researchers model emissions from stratified lakes and reservoirs.
