A molluscan perspective on hydrological cycle dynamics in northwestern Europe

摘要: Shell aragonite delta(18)0 values of unionid freshwater mussels are applied as a proxy for past river discharges in the rivers Rhine and Meuse, using set nine shells from selected climatic intervals during late Holocene. A single Meuse shell derives Subboreal its similar to modern values. The specimens represent Subboreal, Roman Warm Period Medieval (MWP). These also show averages ranges specimens. This indicates that environmental conditions such dynamics, Alpine meltwater input drought severity these were 20(th) century. do not record subtle centennial millennial variation due their relatively short lifespan large inter-annual intra-seasonal conditions. However, they very suitable studying seasonal decadal scale climate variability. two with longest appear variability reconstructed water MWP, possibly forced by North Atlantic Oscillation (NAO), which is dominant mode influencing precipitation regimes over Europe.
