Description :
This multidisciplinary study was undertaken to better understand the long-term climatic changes in the southern interior of British Columbia over the Holocene. Big Lake was identified as a study site because it experienced declines in lake level and increases in salinity coincident with the drought of the late 1980s and early 1990s. In this paper the AA. infer changes in climatic conditions by using floristic changes in the diatom assemblages and associated inferences of salinity, lake level, and nutrients; concentrations and relative abundances of pollen and phototrophic pigments; biogenica silica (BSi); and changes in the proportion of organic and inorganic matter of sediments.
