Discrete chloride and specific conductance (SC) measurements, chloride-SC regression equations, and daily and hourly mean SC values and chloride predictions for 88 USGS water quality monitoring stations in the Delaware River Basin, 2019-2022 Discrete chloride and specific conductance (SC) measurements, chloride-SC regression equations, and daily and hourly mean SC values and chloride predictions for 88 USGS water quality monitoring stations in the Delaware River Basin, 2019-2022
Freshwater salinization, or the increase of dissolved ions like chloride, threaten freshwater streams and rivers across the globe. Continuous (e.g., daily or hourly mean) predictions of chloride concentration were used in an analysis to quantify the extent to which chloride concentrations exceeded ecological thresholds at U.S. Geological Survey (USGS) water quality monitoring sites...
Genomic sequence polymorphisms among Corvus kubaryi of Rota, Northern Mariana Islands, inferred from samples collected between 2014 and 2024 Genomic sequence polymorphisms among Corvus kubaryi of Rota, Northern Mariana Islands, inferred from samples collected between 2014 and 2024
This study generated genetic polymorphism data at a genome scale by whole-genome shotgun DNA sequencing of Mariana Crow (Corvus Kubaryi). DNA was extracted from blood tissue originally collected nonlethally from field monitoring efforts, captive rearing, and carcasses, under permit of the US Fish and Wildlife Service. Sequencing libraries were generated for the Illumina sequencing...
ICP-MS measurements and R Code to determine provenance soil type from analyses of Pinus ponderosa ash collected in Arizona and Colorado ICP-MS measurements and R Code to determine provenance soil type from analyses of Pinus ponderosa ash collected in Arizona and Colorado
Needle samples from 140 Pinus ponderosa were analyzed for trace elements via inductively coupled plasma mass spectrometry (ICP-MS). Samples were collected from eight locations representing five distinct soil types across the Colorado Plateau near Flagstaff, Arizona and Boulder, Colorado. Data includes a full spectral scan between m/z 5-245 which was condensed to 72 dominant atomic masses
Supporting Datasets for Analyses of Sediment Transport and Channel Change in the Puyallup River Watershed (ver. 2.0, February 2026) Supporting Datasets for Analyses of Sediment Transport and Channel Change in the Puyallup River Watershed (ver. 2.0, February 2026)
The Puyallup River and it's major tributaries, including the Carbon and Mowich Rivers, are sediment-rich systems in western Washington State, USA, that flow from glaciated headwaters on Mount Rainier to Puget Sound over a short distance. In the populated Puget Lowlands, sediment deposition and associated loss of flood conveyance has been a chronic issue (Prych, 1988; Czuba and others...
Analysis of historic orthomosaic imagery collected through various agencies for mapping active channel and floodplain changes along a 22.5-km reach of the Green River at Gray Canyon near Green River, Utah from 1938-2021 Analysis of historic orthomosaic imagery collected through various agencies for mapping active channel and floodplain changes along a 22.5-km reach of the Green River at Gray Canyon near Green River, Utah from 1938-2021
The U.S. Geological Survey gathered historic aerial photography and remote sensing imagery from a variety of sources for mapping channel change along a 22.5-kilometer reach of the Green River at Gray Canyon near Green River, Utah. Imagery was downloaded in .TIF format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al. 2021) using Agisoft Metashape...
