The 234Th/238U activity ratios in the near-bottom waters at a station in the South Pacific have been measured. The activity ratios are close to the secular equilibrium value, ranging between 0.9 and 1.13 (± 8%), suggesting that the rate of removal of 234Th by bottom-water scavenging processes at this station is slow compared to its rate of radioactive decay. The mean 234U/238U activity ratios in these waters is 1.14 ± 0.02, the same as the reported values for the world oceans.
