Excess 210Pb inventories and fluxes along the continental slope and basins of the Gulf of Papua

Muhammad, Zahid; Bentley, Sam J.; Febo, Lawrence A; Droxler, Andre W.; Dickens, GR; Peterson, Larry C.; Opdyke, Bradley


Sediment samples were collected from continental slopes and marginal basins in the Gulf of Papua and analyzed for excess 210Pb to elucidate transport processes of fine-grained particles to this region. Estimated excess 210Pb fluxes of 1.0-12.8 dpm cm-2 a-1 were derived from measured seabed inventories. Highest sediment accumulation rates (0.28-0.35 cm a-) were measured along the northeastern shelf edge, and they decrease in seaward directions and along isobaths to the southwest. The excess...[Show more]
