Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Concentration of sertraline and acetaminophen in freshwater mussel (Sagittunio subrostratus) and water from an exposure bioassay Concentration of sertraline and acetaminophen in freshwater mussel (Sagittunio subrostratus) and water from an exposure bioassay
Dataset consists of water and freshwater mussel concentrations of two pharmaceuticals, sertraline and acetaminophen, collected from a 14-day accumulation and 7-day elimination study. Samples (4 replicates) were collected at 0, 4, 12, 48, 96, 168, and 336 hours during the uptake phase of the exposure. Samples (4 replicates) were collected at time point 348, 360, 408, and 504 hours during...
Algorithms for model parameter estimation and state estimation using the Kalman Filter for forecasting, filtering, and fixed-lag smoothing applied to a state-space model for one-dimensional vertical infiltration Algorithms for model parameter estimation and state estimation using the Kalman Filter for forecasting, filtering, and fixed-lag smoothing applied to a state-space model for one-dimensional vertical infiltration
The algorithms in this data release implement a State-Space Model (SSM) of vertical infiltration through the unsaturated zone and recharge to the water table. These algorithms build on previous investigations available at https://doi.org/10.1029/2020WR029110 and https://doi.org/10.1111/gwat.13206. The SSM is defined by observed states (i.e., the water-table altitude) and unobserved...
Sample collection information and microsatellite data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho Sample collection information and microsatellite data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho
This dataset contains sample collection information and microsatellite genotype data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho. This data was collected to examine levels of genetic diversity and connectivity among Black Swift colonies and also to assess parentage at a subset of those sites. This study helps clarify the breeding system of the Black...
Data on black-tailed prairie dog body mass, distance to nearest male and female black-footed ferret, distance to nearest American badger, and reencounter from early to late summer 2005 (Montana) and 2009 (South Dakota) Data on black-tailed prairie dog body mass, distance to nearest male and female black-footed ferret, distance to nearest American badger, and reencounter from early to late summer 2005 (Montana) and 2009 (South Dakota)
Our study was conducted in 2005 on 3 colonies of black-tailed prairie dogs on lands in Phillips County, Montana administered by the Bureau of Land Management and in 2009 on a colony of black-tailed prairie dogs on Buffalo Gap National Grassland, Pennington County, South Dakota managed by U.S. Forest Service. We live-trapped black-tailed prairie dogs in daylight with wire mesh traps and...
Data on the effects of F1-V plague antigen vaccination and deltamethrin dust on black-tailed prairie dog annual survival and flea parasitism, South Dakota, 2007-2009 Data on the effects of F1-V plague antigen vaccination and deltamethrin dust on black-tailed prairie dog annual survival and flea parasitism, South Dakota, 2007-2009
We studied black-tailed prairie dogs (Cynomys ludovicianus) on the Conata Basin, Buffalo Gap National Grassland, South Dakota, USA, 2007-2009. We live-trapped and sampled prairie dogs in 2007 (before known invasion of the plague bacterium Yersinia pestis), 2008 (the year of confirmed invasion), and 2009 (after invasion). Sampling was completed on three 9-ha plots treated annually with...
High resolution water quality and dissolved carbon data from a coastal Louisiana salt marsh from 2019 to 2022 High resolution water quality and dissolved carbon data from a coastal Louisiana salt marsh from 2019 to 2022
Continuous water quality sensor data were collected at USGS 292939089544400 Wilkinson Bayou cutoff north of Wilkinson Bay, LA gage. Field water-quality measurements were collected using a YSI EXO2 water-quality sonde equipped with a data logger to capture hourly data using sensors for measuring water temperature, specific conductance, salinity, pH, oxidation and reduction potential (ORP)
