Advances in understanding of air–sea exchange and cycling of greenhouse gases in the upper ocean
The air–sea exchange and oceanic cycling of greenhouse gases, including carbon dioxide, nitrous oxide, methane, carbon monoxide, and nitrogen oxides, are fundamental in controlling the evolution of the Earth's atmospheric chemistry and climate. Significant advances have been made over the last 10 years in understanding, instrumentation and methods, and in deciphering the pathways of these gases in the upper ocean. And this knowledge is key to determine the effects on oceanic cycling and exchanges due to ongoing warming, acidification, deoxygenation, and eutrophication. We review these advances and suggest that only through a comprehensive, coordinated, and interdisciplinary approach that includes data collection by global observation networks, as well as joint process studies, can the necessary data be generated to address key scientific and societal questions related to greenhouse gases in the ocean.
