Geophysical and direct groundwater data collected on Palmyra Atoll to study fresh/saline groundwater interfaces from 2008 to 2019 Geophysical and direct groundwater data collected on Palmyra Atoll to study fresh/saline groundwater interfaces from 2008 to 2019
The surface ecology of small ocean islands is directly linked to subsurface fresh water resources, which exist in the form of soil water and fresh groundwater lenses. The management of threaten plant species such as the tree Pisonia grandis needs to consider the spatial and temporal dynamics of groundwater lenses, particularly in a time of climate change. The Palmyra Atoll National...
Passive seismic depth to bedrock data collected along headwater stream corridors in the Neversink River watershed, NY, USA Passive seismic depth to bedrock data collected along headwater stream corridors in the Neversink River watershed, NY, USA
The Neversink River watershed (above the Neversink Reservoir) has been a focus of U.S. Geological Survey (USGS) research regarding stream geochemistry, acidification, and ecology dynamics for decades. In 2019, the Water Mission Area Next Generation Water Observing Systems Program augmented the existing stream gage network there, including instrumentation to specifically characterize...
SAR 2018 Native Fish Population and Habitat Study, Santa Ana and San Gabriel Rivers, California SAR 2018 Native Fish Population and Habitat Study, Santa Ana and San Gabriel Rivers, California
This dataset includes 2018 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcutti) in the Santa Ana and San Gabriel Rivers, California.
Numerical Simulation of 1D Advection-Dispersion Equation of Conservative Tracer with Oscillating Tidal Flows Numerical Simulation of 1D Advection-Dispersion Equation of Conservative Tracer with Oscillating Tidal Flows
Model archive for a numerical simulation of the one-dimensional advection-dispersion equation of a conservative tracer with oscillating tidal flows. The numerical simulation was used to examine how a conservative tracer evolves along a tidal channel. Scenarios were run to examine the effects increased dispersion, increased and decreased mixing at a channel junction, and increased...
Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America
This data set contains allele sizes for 8 previously published and 16 novel microsatellite loci, and one microsatellite redesigned for amplification in Merlins (Falco columarius) associated with circadian clock control and polymorphism that has been associated with juvenile dispersal and migratory behavior in some avian species for Merlin (Falco columbarius) from North America (n=21)...
Machine-learning model predictions and rasters of dissolved oxygen probability, iron concentration, and redox conditions in groundwater in the Mississippi River Valley alluvial and Claiborne aquifers Machine-learning model predictions and rasters of dissolved oxygen probability, iron concentration, and redox conditions in groundwater in the Mississippi River Valley alluvial and Claiborne aquifers
Groundwater is a vital resource in the Mississippi embayment physiographic region (Mississippi embayment) of the central United States and can be limited in some areas by high concentrations of trace elements. The concentration of trace elements in groundwater is largely driven by oxidation-reduction (redox) processes. Redox processes are a group of biotically driven reactions in which...
