For the past two centuries, humans have increased the flux oflead (Pb) into the earth surface environment by several fold, peaking atabout 20 fold in the mid-1970’s. Almost all of the Pb in the ocean is fromthese anthropogenic emissions, and it is hard to find places in the oceanwhere the natural Pb is detectable. These emissions provide a global“experiment” on how Pb and other heavy metals move through the ocean.I will present some of the results of oceanic Pb measurements from thepast few decades including the international GEOTRACES project whichis determining the global distribution of trace elements and their isotopes.The perspective from this recent data is supplemented by historicalrecords from the past few centuries contained in corals.
