Geochemical Modeling - Idaho National Laboratory
Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.
Developing Geological Framework - Idaho National Laboratory
As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.

Floodplain trapping and cycling compared to streambank erosion of sediment and nutrients in an agricultural watershed
Floodplains and streambanks can positively and negatively influence downstream water quality through interacting geomorphic and biogeochemical processes. Few studies have measured those processes in agricultural watersheds. We measured inputs (floodplain sedimentation and dissolved inorganic loading), cycling (floodplain soil nitrogen [N] and...
Gillespie, Jaimie; Noe, Gregory; Hupp, Cliff R.; Gellis, Allen; Schenk, Edward R. Unraveling the dynamics of magmatic CO2 degassing at Mammoth Mountain, California
The accumulation of magmatic CO2 beneath low-permeability barriers may lead to the formation of CO2-rich gas reservoirs within volcanic systems. Such accumulation is often evidenced by high surface CO2 emissions that fluctuate over time. The temporal variability in surface degassing is believed in part to reflect a complex interplay...
Pfeiffer, Loic; Wanner, Christoph; Lewicki, Jennifer L. Why large cells dominate estuarine phytoplankton
Surveys across the world oceans have shown that phytoplankton biomass and production are dominated by small cells (picoplankton) where nutrient concentrations are low, but large cells (microplankton) dominate when nutrient-rich deep water is mixed to the surface. I analyzed phytoplankton size structure in samples collected over 25 yr in San...
Cloern, James E. Alternate wetting and drying decreases methylmercury in flooded rice (Oryza sativa) systems
In flooded soils, including those found in rice (Oryza sativa L.) fields, microbes convert inorganic Hg to more toxic methylmercury (MeHg). Methylmercury is accumulated in rice grain, potentially affecting health. Methylmercury in rice field surface water can bioaccumulate in wildlife. We evaluated how introducing aerobic periods into an...

California's landscape is prone to drought and warmer climates. The recent drought lasted five years (2011 – early 2017), bringing with it many environmental issues including the increased prevalence, severity, and duration of wildfires. While there used to be a distinct "wildfire season" in California, the threat of wildfire is no longer restricted to a single season.
