The apparent CFC-11, -12 and -113 ages of Upper Floridan Aquifer water discharged from 31 springs located in Florida and Georgia ranged from 11 to 44 years when samples were collected in 2002 and 2003. Apparent 3 H/ 3 He ages in these springs ranged

In order to study the spatial and temporal variations of radionuclides in the world ocean, five Geochemical Ocean Sections (GEOSECS) stations, located in the different areas of the Arabian Sea, were revisited in 1998, 20 years after the GEOSECS exped

Evidence for the removal of CFC-11, CFC-12, and CFC-113 at the groundwater–surface water interface in the Everglades

Poor agreement between 3 H/ 3 He ages and CFC-11 and CFC-12 ages suggests that CFCs may not be conservative tracers in the Everglades National Park. 3 H/ 3 He ages were used to calculate the expected concentration of CFC-11 and CFC-12 in groundwater

Tritium inventory of the Black Sea

Autor: Zafer Top

Publikováno v: Journal of Environmental Radioactivity. 43:221-229

Tritium and helium-3 measurements from the southern half of the Black Sea are described. A tritium maximum centered at approximately 1200 m and accompanied by a radiogenic helium-3 maximum suggests deep injection of near surface water in the eastern
