Pollen accumulation rates of lacrustine sediment core samples from Baboon Lakes, High Sierra, California

This file plots the age of pollen assemblage of baboon Lakes as pollen accumulation rate (PAR, grains/cm/yr) and percentage of the Upland Sum (%). Samples were processed at the University of Maine according to a modified protocol from Faegri et al. (1989). A known quantity of ceramic microspheres was added to enable us to calculate pollen accumulation rates (3.5 x 104 microspheres/cc). We counted the grains through Poly.Counter at 40x until 300 terrestrial grains were identified.
