Benthic algae community composition data from the Colorado River Basin, Colorado, from 2022-23 Benthic algae community composition data from the Colorado River Basin, Colorado, from 2022-23
This dataset includes benthic algae community composition data in the Colorado River near Cameo, Colorado, U.S. Geological Survey (USGS) site number 09095500, from 2022 to 2023, and from three sites in the upper White River Basin, Colorado, in 2022. Taxonomic classification of algae species is not known well in theses rivers, and this study was conducted to record different algae species...
Hyperspectral profiles of Harmful Algal Blooms (HABs) and other algae, 2022 Hyperspectral profiles of Harmful Algal Blooms (HABs) and other algae, 2022
This dataset is a collection of hyperspectral imagery profiles of algae, many associated with Harmful Algae Blooms (HABs). Data were collected using a microscope-based hyperspectral imaging system with the cooperation of the National Institute of Standards and Technology. Samples were collected from U.S. Geological Survey (USGS) water quality sampling efforts, to include water quality...
Stability testing results for stock solutions to standardize calibration of field fluorescence sensors Stability testing results for stock solutions to standardize calibration of field fluorescence sensors
Optical sensors measuring fluorescence of dissolved organic matter (fDOM) are increasingly used in water quality studies because they provide proxy measurements for a variety of contaminants and constituents of concern including metals and wastewater effluent. Similarly, sensors measuring fluorescence of chlorophyll (fChl) and phycocyanin (fPC) have gained popularity to measure...
Carbon Dioxide Storage Resources-Wind River Basin: Chapter O, Spatial Data Carbon Dioxide Storage Resources-Wind River Basin: Chapter O, Spatial Data
The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common...
Daily Streamflow Data of Swift Reservoir Outflow and Selected Diversions from Birch Creek, Pondera County, Montana, January 2020 through December 2022 Daily Streamflow Data of Swift Reservoir Outflow and Selected Diversions from Birch Creek, Pondera County, Montana, January 2020 through December 2022
In 2019, the U.S. Geological Survey (USGS), in cooperation with the Blackfeet Water Department, initiated a multi-year hydrologic investigation of the Blackfeet Indian Reservation. The investigation was designed to increase understanding of the water resources of the Blackfeet Indian Reservation including Birch Creek which forms the southern boundary of the reservation. Streamflow is...
Hydrologic gridded runoff and routed discharge data for Africa from 2000-2021 Hydrologic gridded runoff and routed discharge data for Africa from 2000-2021
This dataset, VegDischarge v1, represents a significant contribution to the understanding of hydrological dynamics across Africa from 2000 to 2021. It encompasses high-resolution (1km x 1km) monthly raster data of deep drainage, surface runoff, and total runoff, derived from the VegET (VegetationEvapoTranspiration) hydrological model (Senay et al., 2023). Additionally, routed discharge...
