Overview

Randomized trial examines methane oxidation pathways and N2O production in marine cold seeps, indicating significant greenhouse gas implications.

Key Points

  • This research aims to understand how nitrate/nitrite-driven methane oxidation influences N2O production in cold seeps during ecosystem development.
  • Integrated geochemical profiling to quantify process rates.
  • 14C-based labeling to measure methane oxidation rates.
  • Omics-based analyses to identify microbial mediators in cold seep sediments.
  • Early-stage seeps showed nitrate/nitrite-driven methane oxidation rates of 21.9 ± 3.0 mmol C/m2/day, contributing 36%-73% to total methane oxidation.
  • In mature seeps, this contribution dropped to ~1%, with sulfate-dependent methane oxidation becoming dominant.
  • Net N2O production increased by 14%-46% in early-stage sediments, offsetting approximately 41% ± 9% of the climate benefit of methane oxidation.
