Base Cation Weathering Dataset_Whitfield et al 2018_SHC 4.61.4

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2018-05-31
This dataset supports the publication Whitfield et al. (2018) (https://doi.org/10.1007/s11270-018-3691-7). The dataset is a compilation of the estimated base cation weathering rates (BCw) for 44 sites in Pennsylvania under a variety of assumptions to explore key sources of uncertainty in estimates of BCw. BCw is a key variable in the estimates of thresholds (termed "critical loads") of acidification of terrestrial and aquatic ecosystems from atmospheric deposition of NOx and SOx. This dataset is associated with the following publication: Whitfield, C., J. Phelan, J. Buckley, C. Clark, S. Guthrie, and J. Lynch. Estimating Base Cation Weathering Rates in the USA: Challenges of Uncertain Soil Mineralogy and Specific Surface Area with Applications of the PROFILE Model. WATER, AIR, & SOIL POLLUTION. Springer, New York, NY, USA, 229(61): 1-15, (2018).
