Short summary
More and more studies indicate that the open ocean can be a significant source of methane, the second greenhouse gas after CO2. Our study in the subtropical North Atlantic Ocean shows that a significant part of the methane flux to the atmosphere is related to cyanobacteria, which are ubiquitous phytoplankton that produce methane as part of their metabolic activity. This study is a response to the lack of data on the role of the oceans in the methane budget in the context of climate change.
