Correction derived by SIO from analysis of oceanographic situation at time of sampling. ¢ Corrections have been made for dilution where applicable, and for decay during the time of analysioe; counts are given as of 1200 PST S/13/54 (B +218 br). Radloactivity of samples measured with gamois scintillation counter. 3 Average of values for all water samples collected above apparent lower boundary of radioactivity in sea water.
