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.

Site information, probability differences, and entropy-based metrics of streamflow information for the USGS continuous streamflow monitoring network, 1981-2020 Site information, probability differences, and entropy-based metrics of streamflow information for the USGS continuous streamflow monitoring network, 1981-2020
These data sets have at-site values of probability differences and entropy-based metrics to compare the effects of streamflow resolution, monitoring period, and record extension instead of monitoring on streamflow information. Source code for the R functions used to calculate conditional probabilities, conditional entropy, and mutual information are included in a compressed file with...
Niche model results predicting fundamentally suitable and unsuitable habitat for freshwater mussel concentrations in the Meramec Basin Niche model results predicting fundamentally suitable and unsuitable habitat for freshwater mussel concentrations in the Meramec Basin
This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species...
Age Data for River Terraces on the Marsh Creek Anticline (Arctic Alaska, USA) Collected 2023-2025 Age Data for River Terraces on the Marsh Creek Anticline (Arctic Alaska, USA) Collected 2023-2025
These data are in three tables with age data for river terraces on the Marsh Creek anticline, from samples collected at sites along Marsh Creek and the Katakturuk River in Arctic Alaska. The tables include: (1) Carbon-14 ages, (2) Optically Stimulated Luminescence (OSL) age, and (3) Cosmogenic Beryllium-10 concentrations.
Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, WY 2019-2023 Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, WY 2019-2023
This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute suspended sediment concentrations at USGS streamgage 11516530 for water years 2019-2023. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 (https://water.usgs.gov/osw/pubs/memo...
Pallid Sturgeon Habitat Surveys in the Tongue River 2023-2024 Pallid Sturgeon Habitat Surveys in the Tongue River 2023-2024
Endangered pallid sturgeon (Scaphirhynchus albus) spawning habitats were mapped on the Tongue River near Miles, City Montana June in 2023 and 2024. Data quantify the physical characteristics of the river channel and flow; depth, velocity and habitat assessments using single-beam sonar, acoustic Doppler current profilers (ADCPs) in 2023 and single-beam sonar in 2024. Real-time kinematic...
16S rRNA whole-organism microbiome sequencing for larval insects, adult insects, and riparian spiders collected from Torch Lake and Gratiot Lake, Keweenaw Peninsula, Michigan, USA, July and October 2021 16S rRNA whole-organism microbiome sequencing for larval insects, adult insects, and riparian spiders collected from Torch Lake and Gratiot Lake, Keweenaw Peninsula, Michigan, USA, July and October 2021
This data release includes sampling location data, the information about sequenced organisms and the SRA accession number for the 16S whole-organism sequencing data for larval aquatic insects, emergent adult insects, and two riparian spiders from Torch Lake and Gratiot Lake (N=3 sites at each Lake). Torch Lake (Houghton County, Keweenaw Peninsula, Michigan, USA) is a Great Lakes Area of...
