Modeling legacy nitrogen transport under instantaneous, steady-state, and transient groundwater flow conditions Modeling legacy nitrogen transport under instantaneous, steady-state, and transient groundwater flow conditions
In hydrologic settings where groundwater discharge contributes substantially to surface waters, legacy nitrogen in groundwater can confound surface water nitrogen loads estimated exclusively from current terrestrial sources. Additionally, legacy nitrogen in groundwater can contribute to lagged responses to nitrogen management efforts. Some methods of estimating groundwater contributions...
Using quantitative polymerase chain reaction to assess phytoplankton and indicate eutrophication in freshwater rivers: A multiyear nationwide study across the United States Using quantitative polymerase chain reaction to assess phytoplankton and indicate eutrophication in freshwater rivers: A multiyear nationwide study across the United States
Phytoplankton are essential primary producers in fresh surface water that are critical to the health of ecosystems. However, phytoplankton overgrowth due to eutrophication threatens ecological, economic, and public health. Therefore, assessing phytoplankton is fundamental for understanding the productivity, health, and trophic status of freshwater ecosystems. Light microscopy and...
Water table rise sustains carbon release from soils in wetland-dominated landscapes: An intact soil core study Water table rise sustains carbon release from soils in wetland-dominated landscapes: An intact soil core study
Wetland-dominated landscapes influence carbon cycling through their potential to act as both carbon sinks and sources. Wetlands in low-relief landscapes have dynamic terrestrial-aquatic interfaces that change seasonally with variable surface water and groundwater levels. However, few studies have directly quantified dissolved organic matter (DOM) release and greenhouse gas (CO2, CH4)...

Evaluating the Risks of Tire-Derived Compounds to Fish in the Chesapeake Bay Watershed
Tires contain a chemical known as 6PPD which prevents them from quickly breaking down. Microscopic tire particles, generated mainly from the friction of tires on roads, release 6PPD-quinone (6PPDQ) when they come into contact with oxygen. During precipitation events, 6PPDQ can be washed off roads, harming fish in nearby waterways. In response to requests from fishery managers, the USGS is studying...
Interactive Products to Assist with Geothermal Drilling
Geothermal energy is a clean and renewable source of heat derived from the Earth's natural thermal resources. Geothermal borefields are utilized to extract this thermal energy, providing heating for buildings in the winter and cooling in the summer. In New York, the adoption of geothermal energy at both residential and community scales is on the rise and is expected to see significant growth in...
