Survey of potential viral pathogens in the ceca of pen-raised mallards Survey of potential viral pathogens in the ceca of pen-raised mallards
The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and...
Survey of sites for the presence of the nonindigenous benthic foraminifera Trochammina hadai along the west coast of North America from 1930 to 2022 Survey of sites for the presence of the nonindigenous benthic foraminifera Trochammina hadai along the west coast of North America from 1930 to 2022
Results of a survey of samples collected from 1930 to 2022 along the west coast of the United States from Alaska to San Diego, California as well as Honolulu, Hawaii for the presence of the Asian nonindigenous benthic foraminifera Trochammina hadai.
Survey results for yellow-billed Cuckoo occupancy and nesting in xeroriparian habitat in southeastern Arizona from 2013 through 2020 Survey results for yellow-billed Cuckoo occupancy and nesting in xeroriparian habitat in southeastern Arizona from 2013 through 2020
These data were compiled to investigate the distribution and breeding status of yellow-billed cuckoos (Coccyzus americanus) in southeastern Arizona xeroriparian habitat by comparing the results of standardized call-playback surveys to the results of nest searching efforts in the same sites from 2018 to 2020. The primary purpose of the study associated with these data was to determine and...
Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming
We quantified the effects of dam sediment management operations on downstream salmonid spawning habitat during two fall water-level drawdown periods: an experimental drawdown leading to sediment release or a typical slower drawdown intended to minimize release of sediment. The experimental drawdown increased deposited fine sediment and decreased hyporheic dissolved oxygen levels. However...
Suspended Sediment Data and Loads in the Fountain Creek Watershed, Colorado (ver 2.0, June 2025) Suspended Sediment Data and Loads in the Fountain Creek Watershed, Colorado (ver 2.0, June 2025)
This data release consists of daily mean streamflow, daily mean suspended sediment concentration (SSC), and daily mean suspended sediment load (SSL) data for selected U.S. Geological Survey (USGS) streamgage sites within the Fountain Creek watershed, separated by water year. Each file also includes USGS approval levels and any associated qualifiers that were applied to the values. The...
Suspended-sediment concentration and grain size in the San Lorenzo River, coastal California Suspended-sediment concentration and grain size in the San Lorenzo River, coastal California
Water samples were collected from the San Lorenzo River, Santa Cruz, California, and analyzed for suspended-sediment concentration and sand break (proportion of sand vs. silt-plus-clay) at the U.S. Geological Survey (USGS) laboratory in Santa Cruz, California. The samples were all single-vertical samples collected from the thalweg of the river, using a D-95 sampler deployed from a bridge...
SUTRA 4.0.0 SUTRA 4.0.0
This is the software release of SUTRA version 4.0.0.
SWASH Model Water Level Timeseries at Wrightsville Beach, NC during Hurricane Isaias, August 2020 SWASH Model Water Level Timeseries at Wrightsville Beach, NC during Hurricane Isaias, August 2020
This data release contains model output of water level elevation time series generated by the Simulating WAves till SHore (SWASH) model to simulate storm-induced water levels from Hurricane Isaias at Wrightsville Beach, North Carolina (NC), USA. Water levels were simulated along three different cross-shore profiles over a period of 10 hours around the peak of the storm from 2300 GMT on...
SWAT Model Archive for Simulation of Hydrology, Suspended Sediment and Nutrients in Selected Tributary Watersheds of Lake Erie, New York SWAT Model Archive for Simulation of Hydrology, Suspended Sediment and Nutrients in Selected Tributary Watersheds of Lake Erie, New York
This U.S. Geological Survey (USGS) data release contains model scenario input and output files and nine hydrology and water-quality models developed using the Soil and Water Assessment Tool (SWAT). The models represent nine watersheds in eastern New York that drain to Lake Erie or the Niagara River and were created, calibrated, and validated for hydrology, sediment, and nutrients as...
Swim chamber respirometry, aerobic scope, and thermal tolerance experiments with two latitudinally-separated cisco (Coregonus artedi) populations 2022-2023 Swim chamber respirometry, aerobic scope, and thermal tolerance experiments with two latitudinally-separated cisco (Coregonus artedi) populations 2022-2023
These data include aerobic scope and thermal tolerance measurements from two cisco (Coregonus artedi) populations to evaluate performance and potential adaptation to warming Great Lakes habitats. Cisco come from two stock sources: 1) a northern latitude Lake Huron stock collected as gametes from Les Cheneaux Islands, MI, USA in 2015 and raised in a USGS aquaculture lab in Ann Arbor, MI...
Synthetic seismogram data for 3D converted wave reverse time migration imaging of subduction zone structure Synthetic seismogram data for 3D converted wave reverse time migration imaging of subduction zone structure
The dataset consists of synthetic seismograms recorded using the SPECFEM3D wave propagation software. Data from 8 isotropic earthquake sources were recorded at 630 stations while data from 8 realistic earthquakes were recorded at 520.
syntheticdv2lff, Scripts for low-flow frequency (LFF) estimation (and bias correction) from daily mean streamflow estimated at level-12 hydrologic unit code (HUC12) pour points in the southeastern United States syntheticdv2lff, Scripts for low-flow frequency (LFF) estimation (and bias correction) from daily mean streamflow estimated at level-12 hydrologic unit code (HUC12) pour points in the southeastern United States
The syntheticdv2lff repository contains R language source code that document the workflow to compute low-streamflow (low-flow) frequency (LFF) statistics from previously estimated streamflow at level-12 hydrologic unit code (HUC12) pour points (watershed outlet locations) in the south-central and southeastern United States for 1950 through 2010 and associated bias correction. LFF...
