Since bomb-generated C-14 has made a major contribution to total atmospheric C-14, and since its residence time before transfer to the sea is relatively long, the distribution of excess oceanic C-14 was examined to elucidate the processes of ocean- atmosphere exchange, ocean mixing, and bottom water formation and subsequent advective transport.

Intense scavenging from seawater by particulates as a result of the dispersal of hydrothermal solutions in the water column has prevented the assignment of deeper levels at ridge crests as a uranium source or sink. Uranium analyses for hydrothermal solutions from the EPR support earlier data showing that this element behaves coherently with magnesium in its removal from seawater during hydrothermal cir- culation. Results indicate that oceanic crust is subducted with the U/Pb ratio increased relative to that of the ambient mantle, but this is thought to be due more to hydrothermal lead depletion than to uranium enrichment.
