Abstract We carried out time-series observations of 210 Po and 210 Pb radioactivity in the western North Pacific Ocean. The sinking fluxes of particulate organic carbon (POC) in the mesopelagic zone were estimated from 210 Po radioactivity during several seasons in the subarctic and subtropical regi...
