Archive of Chirp Subbottom Profile Data Collected in 2022 From Boca Chica Key, Florida

As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterizing stratigraphy near Boca Chica Key, Florida (FL) in November

Data for Statewide Reconnaissance of Per- and Polyfluoroalkyl Substances in Rivers and Streams of Virginia, 2022-2023

These data were collected in cooperation with the Virginia Department of Environmental Quality (VADEQ) to document the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in streams and rivers of Virginia. Specifically, this effort was initiated to: 1. Collect and analyze samples for PFAS at USGS-sampling stations in the Chesapeake Bay River Input Monitoring Network and Non-Tidal Network; 2

Tiltmeter data from Kīlauea summit stations UWE and SDH from January 1 to December 31, 2020

Tiltmeter data from borehole tilt stations UWE and SDH from January 1 to December 31, 2020, spanning a Kīlauea summit intrusion and summit eruption that began on December 20, 2020. These data were collected in 2020 by Andria P Ellis and Ingrid A Johanson of the USGS Hawaiian Volcano Observatory. The authors thank Sarah Conway for conducting the nearly monthly clock resets for these tiltmeters in 2

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
