| Iodine 129 discharged from nuclear fuel reprocessing plants in France and the United Kingdom is transported into the Nordic Seas on timescales of 3 - 5 years. Tracer I-129 is subsequently injected into intermediate waters that overflow the sills between Greenland, Iceland, and Scotland and ventilate the North Atlantic Deep Waters ( NADW). During the early 1990s, discharges of I-129 increased by 600%, resulting in a large, well- resolved tracer " front'' whose passage through the Nordic Seas is presently being observed by a time series of I-129 measurements on the WOCE ( AR7W) section in the Labrador Sea. The highest I-129 levels were measured below depths of 3000 m in Denmark Strait Overflow Water ( DSOW). These levels increased by about 300% between 1997... |
