1. Tundra

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.

2. Atmospheric transport modelling of HM/POPs over Europe

The aim of this project is to assess the deposition of HM/POP over Europe and to evaluate models. Within the framework of UN-ECE, EMEP Meteorological Synthesising Centre-East (MSC-E Moscow) organised in co-operation with RIVM, a model intercomparison for operational transport models on HM in 1995. In this intercomparison the RIVM will participate with the TREND-model. Results of the intercomparison will also be reported to the OSPAR commission. A model comparison for POPs will follow later. The RIVM/EUROS model is extended with soil and surface water modules in order to improve the description of the exchange process of POPs (deposition and re-emission). With the model, long-term averages of the deposition and accumulatation of POPs are described and scenario-studies can be carried out. In the first instance, Lindane and B(a)P will be taken as examples of POPs dominantly present respectively in the gas phase and attached to particles. When emissions are available the calculations are extended to other POPs.
