Remotely sensed data acquired from an Uncrewed Aerial System (UAS) and field measurements of flow depth and velocity from the North Santiam River, Oregon, collected in July 2022 Remotely sensed data acquired from an Uncrewed Aerial System (UAS) and field measurements of flow depth and velocity from the North Santiam River, Oregon, collected in July 2022
A reach of the North Santiam River, Oregon, was used as a case study in an ongoing effort to develop and test uncrewed aircraft system (UAS)-based salmon habitat mapping techniques using: (1) particle image velocimetry (PIV) for estimating surface flow velocities from remotely sensed data; and (2) two-dimensional (2D) flow modeling based on remotely sensed topography and bathymetry (topo
Remotely sensed data, field measurements, and MATLAB code used to produce image-derived velocity maps for a reach of the Sacramento River near Glenn, CA, September 16-19, 2024 Remotely sensed data, field measurements, and MATLAB code used to produce image-derived velocity maps for a reach of the Sacramento River near Glenn, CA, September 16-19, 2024
This data release provides remotely sensed data, field measurements, and MATLAB code associated with an effort to produce image-derived velocity maps for a reach of the Sacramento River in California's Central Valley. Data collection occurred from September 16-19, 2024, and involved cooperators from the Intelligent Robotics Group from the National Aeronautics and Space Administration...
Repeat Lidar and Orthoimagery of Headwater Streams in the Breitenbush River Basin, Oregon, Summer 2022 Repeat Lidar and Orthoimagery of Headwater Streams in the Breitenbush River Basin, Oregon, Summer 2022
In June and September 2022, NV5 Geospatial collected aerial imagery and near-infrared (NIR) lidar from crewed aircraft over 34 square kilometers of headwater streams in the Breitenbush River Basin in northwestern Oregon. Repeat aerial imagery and NIR lidar data were collected over an area spanning from the northern slope of Triangulation Peak to the mainstem Breitenbush River near the...
Repeat Lidar and Orthoimagery of Headwater Streams in the Donner und Blitzen River Basin, Oregon, Summer 2022 Repeat Lidar and Orthoimagery of Headwater Streams in the Donner und Blitzen River Basin, Oregon, Summer 2022
In June and September, 2022, NV5 Geospatial collected aerial imagery and near-infrared (NIR) lidar from crewed aircraft over 62 square kilometers over headwater streams in the Donner und Blitzen River watershed in southeastern Oregon. Repeat data were collected along Mud Creek and Bridge Creek on the western slope of Steens Mountain. This data release includes orthoimagery and lidar data
Response of natural phytoplankton communities from Green Bay (Lake Michigan) and Maumee Bay (Lake Erie) to laboratory manipulations of nutrient and trace metal availability during late summer 2018 Response of natural phytoplankton communities from Green Bay (Lake Michigan) and Maumee Bay (Lake Erie) to laboratory manipulations of nutrient and trace metal availability during late summer 2018
Microcystins (MC) are a class of cyanotoxins produced by many cyanobacteria taxa. Although toxic to metazoans, the evolution of microcystin pre-dates the appearance of metazoans, and so MC did not originate as a toxin to potential metazoan grazers. One hypothesized functional role of microcystin is the management and acquisition of metals, several of which form complexes with MC...
Responses of Native Freshwater Mussels to Remedial Dredging in the upper Hudson River Responses of Native Freshwater Mussels to Remedial Dredging in the upper Hudson River
The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two General Electric plants over a period of ~30 years and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. Although little is known about mussels in this river, managers were concerned that a 7...
Results from additional dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico - June 2022 Results from additional dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico - June 2022
A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values alongside 12 soil pits dug in the Utuado Batholith, a late Cretaceous age granodiorite pluton located on the northern...
Results from dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico – March 2022 Results from dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico – March 2022
A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 16 sites along three transects on the Utuado Batholith, a late Cretaceous age granodiorite pluton located on the...
Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023 Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023
Bighorn sheep (Ovis canadensis) were frequently photographed by wildlife cameras when they visited desert tortoise (Gopherus agassizii) burrows in the eastern San Bernardino Mountains near Palm Springs, California, USA (Mesa Windfarm). A previous study suggested that sheep may have been utilizing the excavated spoil material from burrows as a mineral lick. We aimed to test this...
Results of generalized least-squares (GLS) regression for 136 USGS streamgages in urban areas in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina (ver. 1.1, January 2026) Results of generalized least-squares (GLS) regression for 136 USGS streamgages in urban areas in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina (ver. 1.1, January 2026)
This dataset contains results of generalized least-squares (GLS) regression for 136 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. GLS regression was used to relate drainage area, percentages of the drainage basins of the streamgages in...

Riparian climate refugia data in western and central USA for 2040-2069 and 2070-2099 Riparian climate refugia data in western and central USA for 2040-2069 and 2070-2099
We mapped potential climate change refugia for riparian areas in the central and western USA for 2040-2069 and 2070-2099. Riparian refugia are existing riparian areas that are projected to maintain riparian vegetation and associated ecological function under plausible future climates. Four input variables were included in the riparian refugia index: two landscape variables that represent...
