Imagery, photogrammetry, lidar, and sensor data collected via small uncrewed aerial systems were used to model stage-streamflow in 19 ephemeral and three perennial streams along the San Juan River near the Four Corners region of the southwestern United St Imagery, photogrammetry, lidar, and sensor data collected via small uncrewed aerial systems were used to model stage-streamflow in 19 ephemeral and three perennial streams along the San Juan River near the Four Corners region of the southwestern United St
Streamflow in a river can be used to calculate loads of constituents of concern in rivers but obtaining streamflow data using traditional streamgaging techniques in ephemeral channels can be cost prohibitive. Because of the remote location and infrequent flow occurrences, collecting paired stage-streamflow measurements for sufficient flow events during a 2-year study to develop a rating...
Morphometric parameters, median and maximum concentrations, and percentages of stream lengths through geologic units for 33 tributary drainage basins of the San Juan River watershed in the Four Corners region, United States Morphometric parameters, median and maximum concentrations, and percentages of stream lengths through geologic units for 33 tributary drainage basins of the San Juan River watershed in the Four Corners region, United States
This data release presents data and calculations for morphometric parameters, median and maximum unfiltered concentrations used in statistical analyses, and stream lengths through geologic units that contain elevated concentrations of constituents of concern used for the publication, "Morphometric and geologic characterization with statistical correlations for 33 tributary drainage...
Nearshore bathymetry at Point Barrow, Alaska, 2022 Nearshore bathymetry at Point Barrow, Alaska, 2022
This data release contains nearshore bathymetry measurements collected at Point Barrow, Alaska in July 2022. These data were collected as part of an effort to monitor and forecast coastal flooding and erosion. They are also intended for reuse by scientists, managers, and the general public.
Geochemical and mineralogical data for core and cuttings samples from wells in the Eocene Green River Formation, Uinta Basin, Utah Geochemical and mineralogical data for core and cuttings samples from wells in the Eocene Green River Formation, Uinta Basin, Utah
Bulk organic geochemical, major and trace element, and mineralogical data have been collected for core and cuttings samples of the Eocene Green River Formation from thirty-four wells in the Uinta Basin of Utah. The samples were collected from the U.S. Geological Survey Core Research Center in Denver, CO and the Utah Core Research Center in Salt Lake City, UT and represent multiple...
Data release for integrating remotely sensed surface water dynamics in hydrologic signature modeling Data release for integrating remotely sensed surface water dynamics in hydrologic signature modeling
Variability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water...
Determination of the concentration and activity of microcystin-LR and degradants after irradiation with 254 nm and 222 nm UV light with Protein phosphatase 2a inhibition assays and high-resolution mass spectrometry using isotope dilution Determination of the concentration and activity of microcystin-LR and degradants after irradiation with 254 nm and 222 nm UV light with Protein phosphatase 2a inhibition assays and high-resolution mass spectrometry using isotope dilution
Microcystin-LR (MC-LR), a cyanotoxin produced during some harmful algal blooms (HABs), can have negative impacts on water ecosystems. Current treatment methods have potential drawbacks: physical removal can cause cell lysis and toxin release, and chemical treatment can cause disinfection byproducts (DBPs). Ultraviolet C (UV-C) treatment can degrade cyanotoxins without producing...
