Project Description:
Atmospheric circulation controls local, regional and global climate with impact on the environment and ecosystems. Preliminary monitoring data from lake Diss Mere in Norfolk suggest that major changes in the lake (overturning, biological productivity and carbonate precipitation) are mainly controlled by climatic parameters. This project aims to estimate the sensitivity of Lake Diss Mere to North Atlantic circulation modes affecting the British Isles’ climate (i.e. the North Atlantic Oscillation- NAO- and the East Atlantic pattern -EA-) during the last two millennia. Research objectives are:
1. To analyse monthly meteorological and limnological datasets to determine how the climate signal is transmitted to the lake system and its sediments.
2. To calibrate proxy data (micro-XRF core scanner data) with instrumental series and reanalysis data in order to identify stationary climate proxies.
3.Evaluate the imprints of the NAO and EA in the proxy-record of Diss Mere.
This research project applies a multidisciplinary approach including lake monitoring, palaeolimnology (sedimentology and geochemistry) and statistical methods.
Policy Impact of Research:
This project will provide key elements to explore barriers to the implementation of adaptation and mitigation strategies.
