      abstract     = {The atmospheric mixing ratios of ethane and its stable
                      carbon isotope ratios (delta C-13) were measured over the
                      North Pacific (2 degrees N to 38 degrees N, 140 degrees E to
                      90 degrees W) during oceanographic cruises in summer and
                      autumn. The measured mixing ratios were relatively low
                      (mostly < 1 ppbv) over the North Pacific, whereas elevated
                      ethane levels (> 1 ppbv) were observed over the western
                      North Pacific near Japan, with lower delta C-13 values
                      (approximately -25 parts per thousand), suggesting recent
                      emissions from neighboring source regions. The most
                      C-13-enriched values of ethane (approximately -16 parts per
                      thousand) were observed over the western equatorial Pacific
                      rather than the central and eastern equatorial Pacific. This
                      is likely caused by the kinetic isotope effect (KIE) for the
                      removal of ethane during the atmospheric transport from
                      potential upwind source regions to the most remote region
                      under the prevailing trade easterly winds. The measurements
                      were compared with the results of a global chemical
                      transport model including two ethane isotopologues
                      ((C2H6)-C-12 and (C2H6)-C-13). The model-estimated delta
                      C-13 values were too high compared with the observations. It
                      is likely that this discrepancy is partly due to an
                      approximately $40\%$ overestimation of the reported KIE for
                      the reaction between ethane and OH radicals.},
