Abstract
The earlierdiscrepancy may be resolved as we can generalize the verticaldistribution of dissolved 210Po with respect to dissolved 210Pbin the sea as the surface deficit, subsurface excess and secularequilibrium below the 500 m or 1000 m depth based on ourmeasurements with great variation of total activities due totheir variation in the sources as well as the amount ofsuspended particulate matter in the water column. An order ofmagnitude greater concentration of dissolved 210Po and 210Pbconcentration activities were present in the interstitial watersof the bottom sediment with 210Po deficit or excess withrespect to 210Pb in the East Sea. Detailed quantitative analysison the distribution, chemistry, flux, and early diagenesis bepresented at the meeting.00 m depth based on ourmeasurements with great variation of total activities due totheir variation in the sources as well as the amount ofsuspended particulate matter in the water column.
