Measurements of the concentrations of the artificial radionuclides /sup 3/H, /sup 137/Cs, and /sup 90/Sr in the northern Irminger Sea in 1972 and 1981 are reported. In both years, tracer measurements from this area included data from samples of the dense overflow water from the north through Denmark Strait. All three tracers were strongly correlated inversely with salinity in the dense outflows-the tracer maxima being related directly to the salinity minimum. When the tracer characteristics in the outflows in 1972 and 1981 were compared, concentrations of all in 1981 were observed to be about double the 1972 values. The individual tracer concentrations-on a decay-corrected, density-normalized basis-were higher in increasing order: /sup 90/Sr(+93%)
