Abstract
DRIED tissues of several marine organisms collected in 1964 from widely separated regions of the North Pacific have turned out to contain 108mAg, a γ-ray emitting man-made nuclide with a half-life reported1 to be greater than 100 yr. This seems to be the first observation cf 108mAg in any organism as the apparent consequence of global fallout. This nuclide promises to be useful for large scale labelling and dating. We have used it to follow the progress of a specific oceanic water mass.
