Rates of surficial sediment mixing and sediment burial are measured in Shagawa Lake, Minnesota, using radionuclide tracers. Based on (106)Ru profiles in 16 cores, mixing rates average 13 sq cm/yr within the upper 9 cm of sediment. Two other nuclides (210)Pb profiles estimate sediment burial rates (about 0.4 cm/yr). Mixing estimates are shown to be fairly insensitive both to uncertainties in sediment burial rates and to temporal patterns of (106)Ru deposition. copyright (c) Pergamon Press Ltd. 1983.)
