Factors affecting nitrate concentrations in stream base flow
Elevated nitrogen concentrations in streams and rivers in the Chesapeake Bay watershed have adversely affected the ecosystem health of the bay. Much of this nitrogen is derived as nitrate from groundwater that discharges to streams as base flow. In this study, boosted regression trees (BRTs) were used to relate nitrate concentrations in base flow...
Wherry, Susan; Tesoriero, Anthony J.; Terziotti, Silvia Small atoll fresh groundwater lenses respond to a combination of natural climatic cycles and human modified geology
Freshwater lenses underlying small ocean islands exhibit spatial variability and temporal fluctuations in volume, influencing ecologic management. For example, The Palmyra Atoll National Wildlife Refuge harbors one of the few surviving native stands of Pisonia grandis in the central Pacific Ocean, yet these trees face pressure from...
Briggs, Martin A.; Cantelon, J; Kurylyk, B.; Kulongoski, Justin T.; Mills, Audrey; Lane, Jr., John W. Stream dissolved organic matter in permafrost regions shows surprising compositional similarities but negative priming and nutrient effects
Permafrost degradation is delivering bioavailable dissolved organic matter (DOM) and inorganic nutrients to surface water networks. While these permafrost subsidies represent a small portion of total fluvial DOM and nutrient fluxes, they could influence food webs and net ecosystem carbon balance via priming or nutrient effects that destabilize...

Mainstems: A logical data model implementing mainstem and drainage basin feature types based on WaterML2 Part 3: HY Features concepts
The Mainstems data model implements the catchment and flowpath concepts from WaterML2 Part 3: Surface Hydrology Features (HY_Features) for persistent, cross-scale, identification of hydrologic features. The data model itself provides a focused and lightweight method to describe hydrologic networks with minimum but sufficient...
Blodgett, David L.; Johnson, J. Micheal; Sondheim, Mark; Wieczorek, Michael; Frazier, Nels A 450-year record of environmental change from Castle Lake, California (USA), inferred from diatoms and organic geochemistry
A 39-cm sediment core from Castle Lake, California (USA) spans the last ~ 450 years and was analyzed for diatoms and organic geochemistry (δ15N, δ13C, and C:N), with the goal of determining sensitivity to natural climate variation and twentieth century anthropogenic effects. Castle Lake is a subalpine, nitrogen-limited lake with ~ 5 ...
Noble, Paula; McGaughey, Gary A.; Rosen, Michael R.; Fuller, Christopher C.; Aquino-López, Marco A.; Chandra, Sudeep Geochemical and geophysical indicators of oil and gas wastewater can trace potential exposure pathways following releases to surface waters
Releases of oil and gas (OG) wastewaters can have complex effects on stream-water quality and downstream organisms, due to sediment-water interactions and groundwater/surface water exchange. Previously, elevated concentrations of sodium (Na), chloride (Cl), barium (Ba), strontium (Sr), and lithium (Li), and trace hydrocarbons were determined to be...
Cozzarelli, Isabelle M.; Kent, Douglas B.; Briggs, Martin A.; Engle, Mark A; Benthem, Adam; Skalak, Katherine; Mumford, Adam; Jaeschke, Jeanne B.; Farag, Aida; Lane, Jr., John W.; Akob, Denise M. Trends in nitrogen, phosphorus, and sediment concentrations and loads in streams draining to Lake Tahoe, California, Nevada, USA
Lake Tahoe, a large freshwater lake of the eastern Sierra Nevada in California and Nevada, has 63 tributaries that are sources of nutrients and sediment to the lake. The Tahoe watershed is relatively small, and the surface area of the lake occupies about 38% of the watershed area (1313 km2). Only about 6% of the watershed is urbanized or...
Domagalski, Joseph L.; Morway, Eric D.; Alvarez, Nancy L.; Hutchins, Juliet; Rosen, Michael R.; Coats, Robert Hydrocarbons to carboxyl-rich alicyclic molecules: A continuum model to describe biodegradation of petroleum-derived dissolved organic matter in contaminated groundwater plumes
Relationships between dissolved organic matter (DOM) reactivity and chemical composition in a groundwater plume containing petroleum-derived DOM (DOMHC) were examined by quantitative and qualitative measurements to determine the source and chemical composition of the compounds that persist downgradient. Samples were collected from a transect down...
Podgorski, David C.; Zito, Phoebe; Kellerman, Anne M.; Bekins, Barbara A.; Cozzarelli, Isabelle M.; Smith, Donald F.; Cao, Xiaoyan; Schmidt-Rohr, Klaus; Wagner, Sasha; Stubbins, Aron; Spencer, Robert G. M. Complexity of groundwater age mixing near a seawater intrusion zone based on multiple tracers and Bayesian inference
Aquifer flow systems near seawater interfaces can be complicated by density-driven flows and the formation of stagnation zones, which inevitably introduces uncertainty into groundwater age-dating. While age-dating has proved effective to understand the seawater intrusion and aquifer salinization process in coastal aquifers, further efforts are...
Ju, YeoJin; Massoudieh, Arash; Green, Christopher; Lee, Kang-Kun; Kaown, Dugin Movement of synthetic organic compounds in the food web after the introduction of invasive quagga mussels (Dreissena bugensis) in Lake Mead, Nevada and Arizona, USA
Introductions of dreissenid mussels in North America have been a significant concern over the last few decades. This study assessed the distribution of synthetic organic compounds (SOCs) in the food web of Lake Mead, Nevada/Arizona, USA and how this distribution was influenced by the introduction of invasive quagga mussels. A clear spatial...
Goodbred, Steven L.; Rosen, Michael R.; Patino, Reynaldo; Alvarez, David; Echols, Kathy R.; King, Kerensa; Umek, John Food web fuel differs across habitats and seasons of a tidal freshwater estuary
Estuarine food webs are fueled by multiple different primary producers. However, identifying the relative importance of each producer to consumers is difficult, particularly for fishes that utilize multiple food sources due to both their mobility and their generally high trophic levels. Previous studies have documented broad spatial differences in...
Young, Matthew; Howe, Emily R.; O'Rear, Teejay; Berridge, Kathleen; Moyle, Peter B. Assessment of NMR logging for estimating hydraulic conductivity in glacial aquifers
Glacial aquifers are an important source of groundwater in the United States and require accurate characterization to make informed management decisions. One parameter that is crucial for understanding the movement of groundwater is hydraulic conductivity, K. Nuclear magnetic resonance (NMR) logging measures the NMR response associated with...
