Validation of chironomid-inferred temperature reconstructions in Iceland : the potential for reconstructing quantitative changes in Holocene climate
Subfossil chironomids in short cores from two lakes in western Iceland were analysed and a chironomidmean July air temperature transfer function applied to produce chironomid-inferred temperature reconstructions for the recent past. These reconstructions were compared with local meteorological data...

Subfossil chironomids in short cores from two lakes in western Iceland were analysed and a chironomidmean July air temperature transfer function applied to produce chironomid-inferred temperature reconstructions for the recent past.
