Transit time distributions and oxygen utilization rates in the Northeast Pacific Ocean from chlorofluorocarbons and sulfur hexafluoride

► CFC11 and SF6 measured concurrently in the North Pacific. ► Transit time distributions (TTDs) constrained with tracer combination CFC11 and SF6. ► Mean transit time of TTDs used, with AOU, to estimate oxygen consumption rates. ► Oxygen consumption rate estimates compared with surface carbon-export rates. ► Meridional trend in integrated oxygen consumption rates estimated for North Pacific.
