Human
activities have altered rates of carbon erosion from soils and carbon
deposition in sediments. We are
developing methods to quantify the present-day and historical effects of these
changes on the carbon mass balance of the conterminous U.S. land surface. Because our analysis uses a combination of
diverse existing datasets, we devote particular attention to methods for the
estimation of uncertainties that are consistent with the statistical character
of the source data.
