Because of high concentrations of authigenic Mn and Fe oxides in surficial sediments from Toolik Lake, Alaska, the normalization of depth and 210 Pb activity scales to the sediment Al content was used for sediment accumulation rate calculations. These results are compared with the conventional 210 P...
