Overall objective is to obtain net fluxes for carbon and freshwater water from an Arctic catchment under base-case and global change scenarios. Objective of the Vrije Universiteit Amsterdam is to study the temporal and patial variability in floodplain sediment balance over the last 2000 years. Research activities: Selected areas in the Usa basin will be studied in detail, both in the zones of continuous and discontiunous permafrost. Fieldwork was and will be conducted in the summers of 1998 and 1999. At selected field sites, the present day processes of river erosion and deposition will be evaluated and the natural evolution and variation of amount and rate of erosion and deposition will be determined for the last 2000 years.
Overall: soil, water, lake sediment, peat cores, sediment samples, discharges, meteorological data, lichens, snow Sampling frequency annually
