This website serves as a community resource for scientists who study oceanic cycling of two potent greenhouse gases, methane (CH4) and nitrous oxide (N2O). It includes information about past and ongoing efforts to standardize and improve measurements of these trace gases, including a recent workshop focused on laboratory analysis of trace gases, our comprehension of the relevant microbial processes, and our observational and predictive capacity to resolve spatial-temporal variability associated with methane and nitrous oxide in the oceans. The intention is to outline the key questions that need to be addressed in the near future and provide practical guidance about how they can be addressed.
