  1. A mean C accumulation rate of 3.6 g C m−2 y−1 was used for the time period post-1950 and 2 g C m−2 y−1 for lakes > 1000 ha.
  2. #The annual burial rate based on the application of a mean C accumulation rate of 3.6 g C m−2 y−1 to lakes > 1000 ha is given in parentheses and is discussed in the text.
