Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data Tables Associated with an Analysis of the U.S. Geological Survey's Historical Water-use Data, 1985–2015 Data Tables Associated with an Analysis of the U.S. Geological Survey's Historical Water-use Data, 1985–2015
The datasets in this data release contain the results of an analysis of the U.S. Geological Survey's historical water-use data from 1985 to 2015. Data were assessed to determine the top category of water-use by volume. Data from groundwater, surface water, and total water (groundwater plus surface water) use were parsed by water type, and the top category of use by county or the...
Denali Fault Zone Field, Microvein, and Microbeam Data, Kluane Ranges, Yukon, Canada Denali Fault Zone Field, Microvein, and Microbeam Data, Kluane Ranges, Yukon, Canada
Detailed geologic mapping and sample collection was conducted in rare bedrock exposures of the Denali fault zone during the summer months of 2013, 2014, and 2015 by the U.S. Geological Survey. Data include measurements of structural geologic orientations and documentation of fault zone and host rock characteristics. Representative samples were selected for measurements of fault vein...
Harmonized discrete and continuous water quality data in support of modeling harmful algal blooms in the Illinois River Basin, 2005 - 2020 Harmonized discrete and continuous water quality data in support of modeling harmful algal blooms in the Illinois River Basin, 2005 - 2020
Harmful algal blooms (HABs) are overgrowths of algae or cyanobacteria in water and can be harmful to humans and animals directly via toxin exposure or indirectly via changes in water quality and related impacts to ecosystems services, drinking water characteristics, and recreation. While HABs occur frequently throughout the United States, the driving conditions behind them are not well...
MODFLOW 6 and MODPATH7 used to simulate regional groundwater flow and advective transport of per- and polyfluoroalkyl substances, Joint Base McGuire-Dix-Lakehurst and vicinity, New Jersey, 2018 MODFLOW 6 and MODPATH7 used to simulate regional groundwater flow and advective transport of per- and polyfluoroalkyl substances, Joint Base McGuire-Dix-Lakehurst and vicinity, New Jersey, 2018
A three-dimensional groundwater flow model using MODFLOW 6 (version 6.2.2) was developed and calibrated for unconsolidated Coastal Plain aquifers underlying the Joint Base McGuire-Dix-Lakehurst (JBMDL) and vicinity, New Jersey, to evaluate groundwater flow pathways of per- and polyfluoroalkyl substances (PFAS) contamination associated with use of aqueous film forming foam (AFFF). The...
Constraints on marsh response to accelerating sea level rise Constraints on marsh response to accelerating sea level rise
Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 387 fixed benchmarks in tidal marshes on four continents measured for an average of 10 years. During this period RSLR at these marshes reached on average 6.6 mm yr-1, compared to 0.34 mm yr-1 over the past millennia. While the rate of sediment accretion corresponded to RSLR, the loss of...
Marine mineral geochemical data - Part One: Pacific Ocean USGS-affiliated historical data Marine mineral geochemical data - Part One: Pacific Ocean USGS-affiliated historical data
This data release compiles element composition data for more than 600 deep-ocean mineral samples from more than 25 research cruises in the Pacific Ocean since 1979 that involved USGS researchers. Deep-ocean mineral sample types encompassed in this data release include ferromanganese crusts, manganese nodules, phosphorites, and hydrothermal minerals. This data release is comprised of both
