Finger Lakes Response to Changing Precipitation Regimes

The Northeastern United States has broadly been seeing a decrease in snowfall, with an increase in rainfall since about the 1980s. The Finger Lakes, which hold water for relatively short time periods, are uniquely positioned to show how this change in preciptiation regimes affect not just water quality, but also how sensitive Central New York is to a ever evolving hydraulic regime. My work here focuses on how we can detect these changes using chemical and physical analyses.

Coupling Groundwater Residence Times with Geochemical Tracers

Understanding controls on chemistry in streams has been a key focus of research in Critical Zone science for some time now. While a growing understanding has emerged pointing towards water-rock interactions as a primary control on stream water chemistry, both the fields of hydrology and low temperature geochemistry have different reasons as to why. Here, we are attempting to look at geochemical tracers and groundwater ages to see how well both correlate with regards to controlling observable stream chemistry

Subsurface Insights from the Cornell University Borehole Observatory (CUBO): A 3km Deep Exploratory Well for Advancing Earth Source Heat Deep Direct-Use Geothermal for District Heating

Published in Proceedings of the 49th Workshop on Geothermal Reservoir Engineering, Stanford, CA, USA, 2024

Motivated by Cornell University’s aspiration to use geothermal heat to replace fossil fuels to heat campus buildings, a 3-km deep geothermal exploratory well, the Cornell University Borehole Observatory (CUBO), was drilled on the Ithaca, NY campus in the summer of 2022. CUBO extends through largely low porosity and low permeability Paleozoic sedimentary rocks…

Rapid response of stream dissolved phosphorus concentrations to wildfire smoke

Published in Nature Communications Earth and Environment, 2024

Wildfires can produce large plumes of smoke that are transported across vast distances, altering nutrient cycling of undisturbed watersheds exposed downwind. To date, wildfire smoke influence on stream biogeochemical signatures remains an important knowledge gap…

Traceable Climate Change and its Impact on the Finger Lakes region of New York: Early Interpretations and Potential Consequences on Long- Term Biogeochemical Cycles

Published:

Presented on how snow to rain climatic transitions are being observed with isotopes and concentration-discharge relationships. The key implication being, that as the Finger Lakes observe increased rainfall, we can expect to see their isotopic composition become more enriched overtime, and that nutrient loading into the lakes should also increase overtime.
