Continuous water-quality data for selected streams in Rocky Mountain National Park, Colorado, water years 2011 - 19 (ver. 3.0, October 2023)

This data release contains water-quality and discharge data collected at seven stream sites and one groundwater spring in Rocky Mountain National Park (RMNP), Colorado by the U.S. Geological Survey (USGS) from 10/1/2010 to 9/30/2019 using in-situ sensors and field meters. Data were collected for the purpose of quantifying downstream transport of aquatic carbon and exchange fluxes of dissolved carb

Interpolated groundwater levels and altitudes for Monroe County, West Virginia, 2017-2019

This interpolated ground-water level altitude product, for Monroe County, WV, was derived from ground-water-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 257 ground-water wells during October 23, 2017 through September 19, 2019, and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of ground-water levels in 50-foot i

Fluorescein and Rhodamine WT concentration and recovery data for select samples collected in Monroe County, West Virginia, in August and September 2019

Fluorescein and Rhodamine WT dye-tracer injections were performed in Monroe County, West Virginia to determine groundwater flow paths and identify the location of the groundwater divide within the Greenbrier karst aquifer in the area south of Union, West Virginia. Fluorescein was injected in a swallet on Burnside Branch upstream of Steel's cave (37° 33' 56.0" latitude -80° 32' 57.6" longitude) and

Soil-Water-Balance forecasted climate model output for simulations of water budget components in the Mississippi Embayment Regional Aquifer System, 2019 to 2055

This data release provides 64 forecasted water budget simulations for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2019 to 2055. Gridded daily data (1-kilometer resolution) include net infiltration (potential groundwater recharge), rejected net infiltration, interception, runoff, runoff outside (runoff that cannot be routed downslope), irrigation, actual evapotranspi

Daily baseflow specific conductance, daily baseflow discharge, and seasonal baseflow discharge and baseflow dissolved solids loads at selected sites within the Colorado River Basin for water years 1980 – 2022

This data release contains three sets of estimated values at selected sites within the Colorado River Basin: 1) daily specific conductance at 143 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); 2) daily baseflow discharge at 100 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); and 3) seasonal baseflow discharge and baseflow dissolved solids load at 14

Thermal maps of the 2018 lower East Rift Zone eruption of Kīlauea Volcano, Island of Hawaiʻi

The 2018 eruption of Kīlauea Volcano included both a large effusive eruption on the lower East Rift Zone and associated collapse and subsidence of the caldera floor at the summit (Anderson and others 2019; Neal and others 2019; Patrick and others 2020).  Lava erupted from 24 fissures on the lower East Rift Zone over four months, with high effusion rates (>100 m3 s-1) often supplying lava into cha

Morphological Measures of Pacific Walruses Collected in the Chukchi and Bering Seas 1970-1991

This dataset contains morphological measures of Pacific walruses sampled in the Chukchi and Bering Seas between 1972 and 1991.

Monte Carlo code for manuscript: Sensitivity testing of marine turbidite age estimates along the Cascadia Subduction Zone

This data release includes the MATLAB code used for sensitivity analysis of turbidite age estimates along the Cascadia subduction zone. The code is written for use in MATLAB and datasets are organized as .mat files. Data values are from Goldfinger et al. (2012) and Staisch (2024). Cited works: Goldfinger, C., Nelson, C.H., Morey, A.E., Johnson, J.E., Patton, J.R., Karabanov, E., Gutiérrez-Pastor,

National scale assessment for rare earth elements in dissolved water samples and supporting geochemistry

This dataset is in support of the publication "The addition of 144Nd to routine ICP-MS analysis as a quick screening tool for approximating earth elements (Q-STAR) in natural waters". It contains inductively coupled plasma mass spectrometry (ICP-MS) data from samples analyzed at the National Water Quality Laboratory (NWQL) from April 2021-May 2022. Data listed include estimated neodymium (Nd) conc

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 New York Wat

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 height in a

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-year remediat
