Abstract
An empirically fitted function describes surface Pacific Ocean tritium concentrations as varying exponentially with latitude, the r.m.s. fit to observations is 18%. The oceanic tritium concentration maximum in the North Pacific, which resulted from nuclear weapons testing, lagged the rain data by two to three years occurring in 1965‐66. Tritium‐salinity correlations are consistent with climatology. Tritium‐longitude correlations are consistent with surface water circulation.
