Aeolian sediment-trap data from the Colorado River corridor in Grand Canyon National Park, Arizona Aeolian sediment-trap data from the Colorado River corridor in Grand Canyon National Park, Arizona
Samples of aeolian (wind-transported) sediment were collected between 2003 and 2010 at multiple locations along the Colorado River corridor within Grand Canyon National Park, Arizona. At each site, sediment being actively transported by wind were collected using a set of four vertically stacked passive samplers (Big Spring Number Eight [BSNE] sand traps). Sediment samples were collected...
Substrate Imagery Classifications for Lake Trout Spawning Habitat in Lake Ontario, 2023-2024 Substrate Imagery Classifications for Lake Trout Spawning Habitat in Lake Ontario, 2023-2024
This dataset is the result of international collaborative efforts by the United States Geological Survey, the United States Fish and Wildlife Service, the New York State Department of Environmental Conservation, the Ontario Ministry of Natural Resources and Forestry, and the Canadian Department of Fisheries and Oceans. These data provide substrate information along the shoreline of Lake...
USGS Isotope: A Database of Radiogenic and Stable Isotopic Data USGS Isotope: A Database of Radiogenic and Stable Isotopic Data
USGS Isotope is a database of compiled radiogenic and stable isotopic data from rocks and critical mineral deposits. The data set contains published elemental concentrations, isotopic ratios, analytical information, sample metadata including location, and source citations. Analytical techniques represented include Sm-Nd, U-Th-Pb, Rb-Sr, Lu-Hf, Re-Os, O, and S isotopic systems. Data...
Biological data associated with skin and liver neoplasm monitoring at the Sheboygan River and Lower Green Bay/Fox River Areas of Concern, Wisconsin, 2021 Biological data associated with skin and liver neoplasm monitoring at the Sheboygan River and Lower Green Bay/Fox River Areas of Concern, Wisconsin, 2021
Datset includes necropsy-based observations including length, weight, sex, visible abnormalities; cellular or histopathological changes including neoplastic and preneoplastic skin and liver lesions; age; transcript abundance of hepatic genes associated with contaminant exposure, carcinogenesis, stress and immune responses and the white sucker hepatitis B virus. These were documented in...
Quantitative polymerase chain reaction data describing target gene silencing in the invasive common reed Phragmites australis subsp. australis using a leaf cutting bioassay Quantitative polymerase chain reaction data describing target gene silencing in the invasive common reed Phragmites australis subsp. australis using a leaf cutting bioassay
These data describe layered double hydroxide (LDH) mediated delivery of novel gene silencing agents (GSAs) in leaf tissue of the invasive common reed Phragmites australis ssp. australis. Double-stranded and hairpin RNAs were designed and synthesized to target paralogous genes coding for phytoene desaturase (PDS) and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). A leaf cutting...
Polar Bear (Ursus maritimus) Genetic Data from the Chukchi Sea Polar Bear (Ursus maritimus) Genetic Data from the Chukchi Sea
This data set provides polar bear (Ursus maritimus) microsatellite genotypes derived from 21 loci (CPH9, CXX20, CXX110, CXX173, G1A, G10B, G10C, G1D, G10H, G10J, G10L, G10M, G10P, G10U, G10X, Mu26, Mu50, Mu51, Mu59, MSUT-2, REN145P07). Blood serum and hair samples for microsatellite genetic analysis were collected from polar bears from the Chukchi Sea between 1986 and 2019. Serum samples...
Multicriteria decision analysis scores for rapid delta smelt decision analysis Multicriteria decision analysis scores for rapid delta smelt decision analysis
These data were compiled to support water management decision-making by the U.S. Bureau of Reclamation and California Department of Water Resources related to the Central Valley Project (CVP) and State Water Project (SWP) operations in water year 2025. The objectives of the study were to use structured decision making to assess tradeoffs between multiple competing water needs and inform...
Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui
This shapefile contains habitat polygons identifying the dominant and major geomorphological structure, biological type and percent cover, and geologic zone for 11 square kilometers of Olowalu reef off west-central Maui at a minimum mapping unit of 100 square meters. Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2)...
Data from laboratory experiments to assess seasonal carbon, nitrogen, and phosphorus processing in water and sediments from the Illinois River near Starved Rock Lock and Dam, 2022. Data from laboratory experiments to assess seasonal carbon, nitrogen, and phosphorus processing in water and sediments from the Illinois River near Starved Rock Lock and Dam, 2022.
Data on carbon and nutrient processing in key locations and over seasonal time scales can provide critical information about the concentrations and potential utilization rates of bioavailable constituents that are known to have a role in cyanobacteria harmful algal blooms (cyanoHABs). Laboratory experiments were performed to measure seasonal nutrient processing rates of carbon, nitrogen...
