Jill S Baron, PhD
Dr. Jill Baron is a senior scientist with the U.S. Geological Survey, and a Senior Research Ecologist with the Natural Resource Ecology Laboratory at Colorado State University.
Jill Baron is founder and Co-Director of the John Wesley Powell Center for Earth System Science Analysis and Synthesis. She was the North American Director of the International Nitrogen Initiative 2014-2019 and is Co-Lead for Component 1 (Tools and methods for understanding the nitrogen cycle) of the International Nitrogen Management System. Baron was President of the Ecological Society of America in 2014, is a Certified Professional Ecologist, and a Fellow of the ESA and the American Association for the Advancement of Science (AAAS).
She was named a Woman of Vision in 2015 by Colorado Women of Influence for her work advancing women’s role in science. Baron has been active in US National Climate Assessment efforts, has given testimony to Congress on western acid rain and climate change issues, and serves on a National Academy of Science, Engineering and Medicine Committee on Assessing Causality from a Multidisciplinary Evidence Base for National Ambient Air Quality Standards. She is founder and Principal Investigator of the Loch Vale Watershed long-term ecological monitoring and research program in Rocky Mountain National Park, an instrumented catchment that in 2022 will celebrate 40 years of continuous records.

Factors influencing precipitation chemistry for the arid west
No abstract available.AuthorsJill BaronSources of dissolved and particulate organic material in Loch Vale Watershed, Rocky Mountain National Park, Colorado, USA
The sources of both dissolved organic carbon (DOC) and particulate organic carbon (POC) to an alpine (Sky Pond) and a subalpine lake (The Loch) in Rocky Mountain National Park were explored for four years. The importance of both autochthonous and allochthonous sources of organic matter differ, not only between alpine and subalpine locations, but also seasonally. Overall, autochthonous sources domiAuthorsJill Baron, Diane M. McKnight, A. Scott DenningChemical weathering in the Loch Vale Watershed, Rocky Mountain National Park, Colorado
Mineralogic, hydrologic, and geochemical data were used to determine the source of solutes to surface waters draining the Loch Vale Watershed (LVWS), an alpine-subalpine drainage located in the Front Range of Colorado. The flux of dissolved solids from LVWS is primarily controlled by interactions between snowmelt and materials derived from the local bedrock; the biomass has only a minor effect onAuthorsAlisa Mast, James I.

No abstract available.AuthorsJill Baron, Kathleen A. GalvinDifferences between nipher and slter shielded rain gages at two Colorado deposition monitoring sites
In the last decade the United States and Canada have made significant progress in establishing spatial ad temporal estimates of atmospheric deposition throughout North America. Fundamental to the wet-deposition portion of these estimates is the accurate and precise measurement of precipitation amount. Goodison and others (I-3) have reported on a new type of shielded snow gage known as the CanadiAuthorsDavid S. Bigelow, A. Scott DenningPhytoplankton dynamics in three Rocky Mountain lakes, Colorado, USA
In 1984 and 1985 seasonal changes in phytoplankton were studied in a system of three lakes in Loch Vale, Rocky Mountain National Park, Colorado. Three periods were evident: (1) A spring bloom, during snowmelt, of the planktonic diatom Asterionella formosa, (2) a mid-summer period of minimal algal abundance, and (3) a fall bloom of the blue-green alga Oscillatoria limnetica.
