In the current era of rapid climate change, accurate characterization of climate-relevant gas dynamics – namely production, consumption, and net emissions – is required for all biomes, especially those ecosystems most susceptible to the impact of change. Marine environments include regions that act as net sources or sinks for numerous climate-active trace gases including methane (CHinline-formula4) and nitrous oxide (Ninline-formula2O). The temporal and spatial distributions of CHinline-formula4 and Ninline-formula2O are controlled by the interaction of complex biogeochemical and physical processes. To evaluate and quantify how these mechanisms affect marine CHinline-formula4 and Ninline-formula2O cycling requires a combination of traditional scientific disciplines including oceanography, microbiology, and numerical modeling. Fundamental to these efforts is ensuring that the datasets produced by independent scientists are comparable and interoperable. Equally critical is transparent communication within the research community about the technical improvements required to increase our collective understanding of marine CHinline-formula4 and Ninline-formula2O. A workshop sponsored by Ocean Carbon and Biogeochemistry (OCB) was organized to enhance dialogue and collaborations pertaining to marine CHinline-formula4 and Ninline-formula2O. Here, we summarize the outcomes from the workshop to describe the challenges and opportunities for near-future CHinline-formula4 and Ninline-formula2O research in the marine environment.
