Data

The U.S. Geological Survey, in cooperation with the Harris?Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District, produced a dataset through 2017 of compaction values in the Chicot and Evangeline aquifers in the Houston?Galveston region, Texas. This dataset contains compaction values of subsurface sediments (mostly...

This dataset describes site location information for samples collected within the western National Parks, USA, (Arches National Park (NP), Bryce Canyon NP, Canyonlands NP, Capitol Reef NP, Dinosaur National Monument (NM), Hovenweep NM, Timpanogos Cave NM, and Zion NP) for water chemistry analyses. Water-quality and bed-sediment samples were analyzed for contaminants of emerging concern...

Modern observations of planktic foraminifera from sediment trap studies help to constrain the regional ecology of paleoceanographically valuable species. Results from a weekly-resolved sediment trap time series (2008-2014) in the northern Gulf of Mexico demonstrate that 92% of Globorotalia truncatulinoides flux occurs in winter (January, February, and March), and that encrusted and non...

This dataset includes information from multiple taxa collected from four main reaches in the Upper Mississippi River Basin, including La Grange reach of Illinois River, Pool 2 of Mississippi River, Pool 19 of Mississippi River, and the St. Croix River. Taxa include hydropsychid caddisflies, chironomids, hexagenia mayflies, threeridge mussels, mapleleaf mussels, Wabash pigtoe mussels...

This dataset includes the field measurements and laboratory analyses of surface water, seston, fish tissue, and sediment samples collected from Bighorn Lake, within Bighorn Canyon National Recreation area (BICA), during high flow (July 2015) and low flow (August 2016) conditions. The study area includes 7-9 sampling sites that follow a transect spanning the entire length of the reservoir...

This data release is comprised of tidal marsh biomass data and spatial predictions of peak biomass and Julian day of peak biomass using data from the Landsat archive. Aboveground biomass dry weight of mixed-species plots (25x50 cm) at a tidal marsh in Willapa Bay, Washington were used to establish a relationship between biomass and tasseled cap greeness (TCG). The julian day of annual...

This data release provides measurements of dye concentration collected to support and validate numerical simulations of dispersion on the Kootenai River, downstream of Bonners Ferry, Idaho. On August 13, 2008, at 06:00, 25.4 kilograms of rhodamine WT was diluted using raw river water in a 378.5 liter tank and released as a nearly single slug. The dye was released near River Kilometer...

Coral reefs around the world have degraded over the last half-century as evidenced by loss of live coral cover. This ubiquitous observation led to the establishment of long-term, ecological monitoring programs in several regions with sizable coral-reef resources. As part of the of the U.S. Geological Survey (USGS) John Wesley Powell Center for Analysis and Synthesis working group "Local...

This data release is the update of the U.S. Geological Survey - ScienceBase data release by Bera and Over (2017), with the processed data through September 30, 2017. The primary data for each year is downloaded from the Argonne National Laboratory (ANL) (Argonne National Laboratory, 2017) and is processed following the guidelines documented in Over and others (2010). Daily potential...

The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data. A Python toolbox for ArcGIS was built to calculate key metrics describing channel and floodplain geometry. Channel and Floodplain Metric Toolbox provides this ability in an automated fashion, allowing for...

This dataset includes marine magnetic data collected by the U.S. Geological Survey (USGS) in 2011 during field activity B-05-11-CC between Point Sur and Piedras Blancas, central California.

This dataset describes water-quantity and -quality data measured from the parking lot influent and underdrain and overflow effluent from the permeable asphalt, concrete and paver test plots in Madison, Wisconsin, USA. Data include precipitation statistics, volumes, and concentrations and loads of total and dissolved forms of solids, nutrients, chloride, and bacteria. Samples were...
