Atmospheric composition study based on ship measurements in the Russian Arctic seas in summer 2019
Abstract We present observation results of methane (CH 4 ), its isotopic signature (δ 13 C CH4 ) and carbon dioxide (CO 2 ) surface concentrations, made aboard the research vessel (R/V) “Akademik Mstislav Keldysh” in the Russian Arctic seas in summer 2019. The main goal of the study is to determine...
