| Abstract: | High concentrations of tritium are found in the surface water of the Arctic Ocean (up to 50 TU) and in the East Greenland Current (up to 70 TU). These high tritium values are a direct result of atmospheric testing of nuclear weapons in the early 1960's. A box model with a time-dependent input of highly tritiated precipitation predicts that high tritium concentrations are to be expected in the surface layer of the Arctic Ocean and its various outflows. We suggest that a few tritium stations in the Arctic Ocean would provide a powerful analytical tool for assigning time scales to exchange processes. |
