Ethan is a hydrogeologist for the Aquifer Mapping Program. Since starting with the Bureau of Geology, he has worked on a variety of projects covering many parts of the state. These studies have required a broad range of hydrogeologic tools, such as GIS based aquifer and water-level surface interpolation, geochemical analysis of groundwater and surface water, and groundwater modeling. He has experience covering most facets of research projects, ranging from field sampling, report writing, to figure drafting.

Education

  • University at Buffalo, The State University of New York
    Masters of Science, Hydrogeology, May 2013
    Advisor: Christopher S. Lowry, PhD
    Thesis: “Two-dimensional quantification of groundwater flux using heat as a groundwater tracer: Applying amplitude shift methods to distributed temperature measurements”
  • Beloit College, Beloit, WI
    Bachelor of Science, Geology, May 2010
    Advisor: Susan K. Swanson PHD
    Undergraduate Thesis: "A climatic study of spring tufa deposits using stable isotopes and major and trace element concentrations, southwestern Wisconsin”

Current Research Interests

  • Expanding the use of heat as a tracer in quantifying groundwater/ surface water interactions.
  • Using fiber-optic distributed temperature sensing (FO-DTS) to better monitor managed aquifer recharge.
  • Finding ways to apply new and existing technologies to find creative solutions to hydrologic questions.
  • Studying long term groundwater storage changes throughout the state, in both confined and unconfined aquifers.

Projects

  • Estimates of recharge in the Tularosa Basin.
  • Modeled playa infiltration and spring discharge in the Jornada del Muerto.
  • Created isopach and structural contour maps of the geologic units in the San Juan Basin.
  • Mapped aquifer storage changes and water-level decline throughout the Rio Grande drainage basins.
  • Calculated canopy interception rates in the Sacramento Mountains.
  • Monitored the interaction of surface water and groundwater along the Animas River.
  • Studied the impact of a changing regional hydrogeology on a gypsum dune field in the Cuatrociénegas Basin, Coahuila, MX.
