Data

This dataset provides estimated daily ice cover fractions for 107,257 lakes across the Northern Hemisphere from 1980 to 2022. The ice cover fractions were generated using a deep learning model trained on Landsat observations. The model's code is publicly available in the USGS GitLab repository: https://doi.org/10.5066/P13ZGUGE. The dataset consists of 42 CSV files, each corresponding to...

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...

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...

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.

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...

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...

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...

Data include position data from a VEMCO Positioning Systems (VPS) array at the mouth of the Lamine River. The array was deployed September 3rd and retrieved October 2nd. Position data was generated for all tagged fish detected in the VPS array using Fathom Position software. The data includes 3946 positions for 26 detected tags. The array was deployed as part of a project to remove...

This dataset includes a collection of files related to a project investigating the ecology of six lakes in the Tokopah Basin. The primary purpose of the research project was to understand the dynamics of periphyton growth and the potential relationships with nitrogen and copper concentrations in high elevation lakes of the Sierra Nevada mountains in Sequoia National Park, California...

Tabular and raster data containing spatial capture recapture, GPS telemetry, ground observations, and genetic records for male and female Rocky Mountain bighorn sheep (Ovis canadensis canadensis) in Dinosaur National Monument from 2006 to 2022. Includes associated tabular data files required for analysis of data with spatial capture models and resource selection models, and the raster...

This data set includes concentrations of selected transformation products (TPs) of the tire antioxidant, 6PPD, including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA) in water samples collected during a rain event from two urban rivers in the Greater Toronto Area, Ontario, Canada. In addition, mortality data from acute toxicity tests with aquatic larvae of the mayfly...

The dataset includes capture and individual data for silver carp and buffalo from 2022 and 2023. Fish were captured in the Missouri River and tributaries and transported to the Columbia Environmental Research Center, Columbia, MO, USA. Fish were assigned to one of four treatments to examine different sedation techniques for surgical implantation of artificial transmitters: tricaine...
