Data

Data from an optical turbidity sensor deployed at the stream station were recorded at 15-minute intervals by a data logger and uploaded every hour to the U.S. Geological Survey (USGS) database (Anderson, 2005; Wagner, 2006). Suspended-sediment samples were collected using equal width increments or grab sampling techniques (Edwards, 1999). The use of an optical sensor to continuously monitor turbid

Data from an optical turbidity sensor deployed at the stream station were recorded at 15-minute intervals by a data logger and uploaded every hour to the U.S. Geological Survey (USGS) database (Anderson, 2005; Wagner, 2006). Suspended-sediment samples were collected using an ISCO automatic sampler (suction pump), equal width increments or grab sampling techniques (Edwards, 1999). The use of an op

The U.S. Geological Survey, in cooperation with the Tennessee Department of Transportation, conducted an investigation of acid-rock drainage from road cuts in Tennessee during 2014-2015. The Devonian Chattanooga Shale contains disseminated pyrite and is a primary producer of acid-rock drainage (ARD) in Tennessee. One objective of the overall investigation was to attenuate ARD by manipulating the i

The U.S. Geological Survey, in cooperation with the Savannah Valley Utility District, evaluated the groundwater hydrology of the Valley and Ridge carbonate aquifer system of Cambrian-Ordovician age in the area of Savannah and Gunstocker Creeks in northeastern Hamilton, southern Meigs, and northwestern Bradley Counties, Tennessee, from 2007 through 2009. The evaluation included and built on: 1) the

This data release contains habitat survey data (quantitative and qualitative) and biological assemblage data (periphyton, macroinvertebrate, and fish) collected among 8 stream sites within the Tribal lands of the Pearl River Community of the Mississippi Band of Choctaw Indians (MBCI). The MBCI is a Federally recognized Native American Tribe and the Pearl River Community, located near Philadelphia,

Karst environments present many challenges to agencies and engineers attempting to work in these landscapes, particularly towards building infrastructure. The interconnectivity of karst hydrologic systems means that activities occurring on the surface of a karst landscape can have an impact on water quality and quantity. Additionally, soil thickness in karst landscape is often highly variable due

The Chicot aquifer system is a vital water resource for Southwestern Louisiana, providing nearly half of the fresh groundwater the region consumes (Sargent, 2011). The aquifer’s surficial confining unit consists of a wedge-shaped thickening sequence of south to southeastern dipping, interbedded clays and courser material (primarily sand and gravel). In collaboration with the Louisiana Department o

Reelfoot Lake, in northwestern Tennessee and southwestern Kentucky, is home to a Federal wildlife refuge, a State wildlife-management area, and to a tourism industry that is based on hunting, fishing, birding, and the area’s unique cultural history. In 2012, the U.S. Geological Survey, in cooperation with the Tennessee Wildlife Resources Agency, began a series of hydrologic investigations to suppo

The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings help the MDOT

The recent completion of the US Army Corps of Engineers (USACE) Hurricane and Storm Damage Risk Reduction System (HSDRRS) for New Orleans has effectively blocked surface water exchange between Bayou Sauvage National Wildlife Refuge (BSNWR) and the surrounding Lake(s) Pontchartrain and Borgne and the Gulf of Mexico to which it was once connected. Monitoring changes in hydrology, water quality, bird

This data release contains in situ biomass samples collected from cereal grain winter cover crop fields at the USDA-ARS Beltsville Agricultural Research Center, Beltsville, MD, in the winters of 2019-20 and 2020-21. It also contains corresponding spectral reflectance and radar data acquired from the Sentinel-2 and Sentinel-1 satellite platforms on dates proximal to the biomass collection. Data are
