Measurements of Acid-Neutralizing Capacity, Conductance, and Calcium Concentrations in Adirondack Headwater Streams of New York, 1988 to 2022 Measurements of Acid-Neutralizing Capacity, Conductance, and Calcium Concentrations in Adirondack Headwater Streams of New York, 1988 to 2022
This data release contains measurements of acid-neutralizing capacity, conductance at 25 degrees Celsius, and Ca concentrations for headwater stream samples collected from 1988 to 2022 in the Adirondack region of New York. Sample analyses were performed by the Adirondack Lake Survey Corporation (ALSC) laboratory and are adjusted here to be consistent with measurements made in the USGS...
Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2023 Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2023
The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2023. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...
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...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional oil and gas resources in the Smackover formation in the U.S. Gulf Coast. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context...
Topographic and multispectral reflectance products, aerial imagery, ground spectra, vegetation, and associated GPS data collected during uncrewed aircraft system operations - Dog Head Marsh at South Cape Beach, Mashpee, MA, October 7-8, 2021 Topographic and multispectral reflectance products, aerial imagery, ground spectra, vegetation, and associated GPS data collected during uncrewed aircraft system operations - Dog Head Marsh at South Cape Beach, Mashpee, MA, October 7-8, 2021
The purpose of this field data collection was to test and compare the OceanInsight HDX Mini Spectrometer as an accessible alternative against the more expensive ASD Fieldspec for collecting ground-based hyperspectral reflectance profiles for landcover analysis. The data collection took place in Dog Head Marsh and South Cape Beach within the Waquoit Bay National Estuarine Research Reserve...

This data release includes metadata and tabular data documenting the reproductive demography of the Samoan swallowtail butterfly (Papilio godeffroyi), including rates of parasitism by two species of Ooencyrtus wasp. Data was collected at approximately monthly surveys of marked host trees (Micromelum minutum) at eight forest stands, mostly in or adjacent to the National Park of American...
Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2022 Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2022
Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2022 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications...
Water column and sediment incubations to measure dissolved organic matter dynamics in the Fox rivermouth (Lake Michigan; 2016-2017) Water column and sediment incubations to measure dissolved organic matter dynamics in the Fox rivermouth (Lake Michigan; 2016-2017)
These data are associated with experiments performed in 2016 and 2017 in the Fox rivermouth (Green Bay, WI; Lake Michigan). Between the De Pere Dam and the Lake Michigan coastline, we performed experiments to measure water column transformation of dissolved organic matter (DOM) and sediment flux of DOM. These experiments consisted of incubations of surface water or intact sediment cores...
