The Radiocarbon Method to Estimate Primary Production in Aquatic Environments,g 1960). Primary production is the basic source of external energy input into most aquatic ecosystems. Therefore, any attempt to estimate or model their energy balances first needs adequate evaluation of the size of primary production. The parameters of primary production per day and per whole seaso

Use of Radioisotopes to Study Biogeochemical Cycling of Elements in Aquatic Environments,r basins (Kuznetsov 1970; Krumbein 1978). Among the most important of them are C, N, P, S, Ca, Mn, Fe, and Co. All of them have long-living radioisotopes except nitrogen, which also has the radioisotope (.N), which is very short-living. Its half-life is only 10 min. Nevertheless, it was also used fo
