Abstract Aerobic methane production from biological methylphosphonate degradation contributes to the observed supersaturation of oceanic methane in oxygenated surface waters. Atmospheric deposition is an important nutrient source and this process can affect nutrient ratios and biogeochemical cycle in the upper ocean. Here we present evidence that atmospheric nitrogen deposition modulates methane production by impacting microbial phosphorus acquisition.

Abstract Coral reefs are iconic ecosystems that support diverse, productive communities in both shallow and deep waters. However, our incomplete knowledge of cold-water coral (CWC) niche space limits our understanding of their distribution and precludes a complete accounting of the ecosystem services they provide.

Abstract Methane is supersaturated in surface seawater and shallow coastal waters dominate global ocean methane emissions to the atmosphere. Aerobic methane oxidation (MOx) can reduce atmospheric evasion, but the magnitude and control of MOx remain poorly understood. Here we investigate methane sources and fates in the East China Sea and map global MOx rates in shallow waters by training machine-learning models.
