Small Unoccupied Aircraft System Imagery and Associated Data used for Discharge Measurement at Eight Locations Across the United States in 2019 and 2020 Small Unoccupied Aircraft System Imagery and Associated Data used for Discharge Measurement at Eight Locations Across the United States in 2019 and 2020
A series of field measurements of surface water velocity derived from video collected by small unoccupied aircraft systems (sUAS) was conducted at eight locations in Arizona, New Mexico, California, and Maine, USA during the summers of 2019 and 2020. The measurements are utilized to compute surface velocity and discharge using the Large-Scale Particle Image Velocimetry (LSPIV) image...
Data and scripts used in water-quality trend and load analysis in the Heart River Basin, North Dakota, 1970-2020 Data and scripts used in water-quality trend and load analysis in the Heart River Basin, North Dakota, 1970-2020
A comprehensive study to evaluate salinity and nutrient conditions in the Heart River Basin, North Dakota was completed by the U.S. Geological Survey (USGS) in cooperation with the Natural Resources Conservation Service and the Grant County Soil Conservation District. In this dataset three zipped folders are provided which contain all files necessary to run trend, load, and geochemical...
Report to NECSC: Adaptive capacity in a forest indicator species Report to NECSC: Adaptive capacity in a forest indicator species
Data contain metabolic rates of red-backed salamanders (Plethodon cinereus) exposed to different thermal regimes, and the movements of salamanders marked with PIT tags and exposed to electromagnetic fields.
LCMAP CONUS Geographic Assessment Data Tables v1.0 1985-2016 LCMAP CONUS Geographic Assessment Data Tables v1.0 1985-2016
This is a collection of data tables supporting the LCMAP CONUS Geographic Assessment v1.0. The data used to generate these tables come from the USGS LCMAP reference dataset and the map products released by LCMAP. Tables include annual land cover class composition and annual rate of land cover change metrics developed with a post-stratified estimator. Other tables including annual gross...
Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019 Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019
This data release presents data that were collected as part of a larger effort to assess factors that regulate ecosystem metabolism in small ponds. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). From May to October 2019, dissolved oxygen, temperature, and light were measured throughout the water-depth profile of...
Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025) Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025)
This dataset contains information from surveys conducted 2016-2024 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2024 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water...
