Continuous measurement of dissolved methane in surface ...

Global oceanic contribution to the methane (CH4) atmospheric burden is estimated to range between and Tg yr-1. However, uncertainties associated with these estimates are quite large. Given the critical role of CH4 in atmospheric chemistry, a better characterization of its sources and sinks is needed in order to improve climate predictions.
