The workshop agenda addressed the overarching question 'Where in the global oceans should spatial and temporal surveys be conducted to discern climatologically-relevant changes in water-column inventories of methane and nitrous oxide?' Therefore we first evaluated our existing knowledge and then discussed how to address the gaps to achieve a more complete understanding of methane and nitrous oxide in the marine environment. The agenda was shaped with input from participants and the wider community prior to the workshop.

Summary of meeting and discussion items

Small group discussions

During Monday’s science talks we will make a list of potential small group discussions for the Tuesday.  A  few suggestions have emerged during the planning of the workshop and are highlighted below.

Coordination of repeat hydrographic and time-series measurements

Integrative approaches between metagenomic mining of methane and nitrous oxide production pathways and incubation experiments

Methane and/or nitrous oxide in specific habitats such as the Arctic, oxygen minimum zones, freshwater/estuarine, or coastal/shelf

Developing SOPs for methane and nitrous oxide measurements
