Data

This U.S. Geological Survey data release contains datasets that combine past data with future projections of nitrogen sources and nitrogen export to the Chesapeake Bay watershed for the years 1950-2050. To help understand the effect of human and environmental changes over this time period, data for nitrogen sources from wastewater, agricultural fertilizer and manure, and atmospheric deposition are

This data release includes data processing scripts, data products, and associated metadata for a study investigating trends in Mississippi River (MR) nitrogen and phosphorus loads to the Gulf of Mexico. This data release consists of three main components: 1) Nitrogen and phosphorus balances, which account for major nutrient inputs (fertilizer, manure, waste water treatment facility effluent, atmos

This data release includes videos acquired from a helicopter and field measurements of flow depth and velocity from the Tanana River near Nenana, Alaska, obtained on July 24, 2019. This parent data release includes links to child pages for two data sets produced during the study: 1. Acoustic Doppler Current Profiler (ADCP) field measurements of flow depth and velocity from the Tanana River, Alas

Rio Tinto, Spain, is an example of a fluvial system strongly influenced by acid rock and acid mine drainage. During the spring of 2018 and 2019, samples of stream waters and mine waters, biofilms, sediments and rocks, were collected in the field by Aubrey Zerkle. These samples were analyzed for comprehensive geochemistry, including Cr isotope geochemistry, anions and cations. Mineralogical analysi

A large spill of wastewater from oil and gas operations was discovered adjacent to Blacktail Creek near Williston, North Dakota in January 2015. To determine the effects of this spill on streambed microbial communities over time, bed sediment samples were taken from Blacktail Creek upstream, adjacent to, and at several locations downstream from the spill site. Blacktail Creek is a tributary of the

Ephemeral springs and other groundwater sources in Pinnacles National Park (San Benito and Monterey Counties, CA) were sample in the Spring and Fall of 2015-2017 during several field visits. Field parameters such as in-situ pH, TDS/conductivity, and temperature were assessed. GPS coordinates for all samples were taken. Comprehensive water chemistry, including major and minor elements, alkalinity,

This U.S. Geological Survey (USGS) data release consists of two hydrographic datasets with spatial modeling units consistent with the National Hydrologic Model (NHM) Geospatial Fabric for National Hydrologic Modeling (abbreviated within this document as GFv1, Viger and Bock, 2014). The two datasets found as subpages to this landing page are 1) the GIS (geographic information system) features of th

Evaluating technologies and approaches to identify the movement of fine sediment over coarser substrate has implications for monitoring the condition of habitat restoration sites. This goal motivated testing the efficacy of Fiber Optic Distributed Temperature Sensing (FO-DTS) as a technique for detecting the migration of sand bedforms over coarser bed material. Experiments were conducted in a labo

This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wells within the oil zone and groundwater monitoring wells away from the oiled zone at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji MN (USA) from 1985-2015. The site located in Beltrami County is where a high-pressure pipeline carrying crude oil burst in 1979 and spilled approximat

A Geographic Information System (GIS)? shapefile and summary tables of irrigated agricultural land-use are provided for Broward and Miami-Dade Counties, Florida compiled through a cooperative project between the U.S Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the locations in

The U. S. Geological Survey- Water Resources Mission Area is currently developing Integrated Water Availability Assessments (IWAAs) - multi-extent (regional and national), stakeholder driven, near real-time water availability census and prediction for human and ecological uses. To provide appropriate user accessibility to data delivery systems developed for IWAAs, a user-centered design process in

This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wastewater (including flowback and produced water) samples, co-produced with natural gas, collected from the Marcellus Shale Energy and Environment Laboratory (MSEEL) site. MSEEL is a long-term field site and laboratory at the Northeast Natural Energy LLC (NNE) production facility, adjacent to the Monongahela River,
