A method for error analysis of sediment yields derived from estimates of lacustrine sediment accumulation

Description :
In this paper data from a series of alpine lakes in British Columbia are applied to develop a new method for deriving error estimates for measured sedimentary parameters. Regression surfaces fitted to point values of sediment mass are used to model the physically controlled spatial variability of sedimentation. Deviations from these surfaces are assumed to represent remaining unstructured variance, which constitutes a conservative error estimate. The associated gains in precision justify multicore approaches to lake sediment-based reconstructions of sediment yield.
