New trace gases short film from 2018 Workshop
In October 2018, an Ocean Carbon- and Biogeochemistry workshop addressed questions to help determine the future directions of methane and nitrous oxide measurements in the global oceans. The objective was to define the key questions that need to be addressed in the near future and provide practical guidance about how they can be addressed.
