Sarah Stackpoole
Sarah Stackpoole is a Research Ecologist for the USGS Water Resources Mission Area.
I am a Research Ecologist with the US Geological Survey in Denver. I completed my undergraduate studies at the University of Michigan-Ann Arbor, my graduate studies at the University of Wisconsin-Madison, and I joined the USGS in 2009. I use field studies along with large-scale data assimilation and statistical approaches to document surface water quality status and trends. I also use a variety of methods to integrate water quality metrics with climate and land-use datasets to identify drivers of change in surface water quality and potential stressors on human and aquatic ecosystem health.
Current and Past Projects:
- National Scale Interpretation of Pesticides, PFAS, and Geogenic Constituents in Surface and Groundwater (2023 – Present) Project Leader, Quantify changes in surface and groundwater pesticides, PFAS, and geogenics and determine if the changes affect water availability for either human or ecological use.
- Harmful Algal Blooms (2020 - Present) Assess the vulnerability of river systems to harmful algal blooms at a regional to national scales.
- Integrated Water Availability Assessments (2020 - Present) Identify drivers of change in surface water quality and potential stressors on human and aquatic ecosystem health.
- National Water Quality Assessment - Surface Water Status and Trends (2018 - 2021) Document the impact of current and past anthropogenic phosphorus sources on soil saturation and water quality. Characterize the occurrence and distribution of pesticides in surface waters.
- USGS LandCarbon Team (2009 - 2017) Assimilate large-scale datasets and determine the best statistical models and extrapolation methods to provide an assessment of current rates of freshwater carbon storage, transport, and emissions for the conterminous United States and Alaska.

Organic carbon burial in lakes and reservoirs of the conterminous United States
Organic carbon (OC) burial in lacustrine sediments represents an important sink in the global carbon cycle; however, large-scale OC burial rates are poorly constrained, primarily because of the sparseness of available data sets. Here we present an analysis of OC burial rates in water bodies of the conterminous U.S. (CONUS) that takes advantage of recently developed national-scale data sets on reseAuthorsDavid W. Clow, Sarah M. Stackpoole, Kristine L. Verdin, David E. Butman, Zhi-Liang Zhu, David P. Krabbenhoft, Robert G. StrieglThe river as a chemostat: fresh perspectives on dissolved organic matter flowing down the river continuum
A better understanding is needed of how hydrological and biogeochemical processes control dissolved organic carbon (DOC) concentrations and dissolved organic matter (DOM) composition from headwaters downstream to large rivers. We examined a large DOM dataset from the National Water Information System of the US Geological Survey, which represents approximately 100 000 measurements of DOC concentratAuthorsIrena F.

StackpooleThe impact of climate and reservoirs on longitudinal riverine carbon fluxes from two major watersheds in the Central and Intermontane West
A nested sampling network on the Colorado (CR) and Missouri Rivers (MR) provided data to assess impacts of large-scale reservoir systems and climate on carbon export. The Load Estimator (LOADEST) model was used to estimate both dissolved inorganic and organic carbon (DIC and DOC) fluxes for a total of 22 sites along the main stems of the CR and MR. Both the upper CR and MR DIC and DOC fluxes increAuthorsSarah M. Stackpoole, Edward G. Stets, Robert G.

The Energy Independence and Security Act of 2007 (EISA) requires the U.S. Department of the Interior (DOI) to develop a methodology and conduct an assessment of carbon storage, carbon sequestration, and greenhouse-gas (GHG) fluxes in the Nation's ecosystems. The U.S. Geological Survey (USGS) has developed and published the methodology (U.S. Geological Survey Scientific Investigations Report 2010-5AuthorsZhi-Liang Zhu, Sarah StackpooleLooking beyond fertilizer: Assessing the contribution of nitrogen from hydrologic inputs and organic matter to plant growth in the cranberry agroecosystem
Even though nitrogen (N) is a key nutrient for successful cranberry production, N cycling in cranberry agroecosystems is not completely understood. Prior research has focused mainly on timing and uptake of ammonium fertilizer, but the objective of our study was to evaluate the potential for additional N contributions from hydrologic inputs (flooding, irrigation, groundwater, and precipitation) andAuthorsS.M.

he Energy Independence and Security Act of 2007 (EISA), Section 712, mandates the U.S. Department of the Interior to develop a methodology and conduct an assessment of the Nation’s ecosystems, focusing on carbon stocks, carbon sequestration, and emissions of three greenhouse gases (GHGs): carbon dioxide, methane, and nitrous oxide.
