Continuous measurement of air–water gas exchange by underwater eddy covariance [PDF]

open access: yesBiogeosciences, 2017
Exchange of gases, such as O2, CO2, and CH4, over the air–water interface is an important component in aquatic ecosystem studies, but exchange rates are typically measured or estimated with substantial uncertainties.
