Mercury contamination in Annas hummingbirds

Heavy metal contamination (n=17 metals) of feather and tissue samples from live and deceased Anna's hummingbirds (Calypte anna) was evaluated. Feathers taken from live birds are low in sample weight, therefore a novel method was used in feather sample preparation. Feather samples were then analyzed utilizing an inductively coupled plasma mass spectrometry (ICP-MS) assay. In addition, ICP-MS was us

Data for Comparison of Size, Terminal Fall Velocity, and Density of Bighead, Silver, and Grass Carp Eggs for use in Drift Modeling

Invasive Asian carps established in the United States spawn in turbulent water of rivers and their eggs and early larvae develop while drifting in the current. The eggs are slightly denser than water and are held in suspension by water turbulence. The eggs are believed to perish if they settle before hatching. It is thus possible to use egg drift modeling to assess the capability of a river to s

Replicate surface water and groundwater data analyzed by USGS National Water Quality Laboratory schedule 2437, 2013-15

Replicate water-quality samples are collected and prepared in the field and analyzed in the laboratory in identical ways so that they are considered to be the same in composition and analysis (Mueller and others, 2015). This data set includes one table of duplicate National Water-Quality Assessment Project (NAWQA) surface water and groundwater samples collected between October 1, 2012 and Septembe

Model climate scenario output Upper Charles river basin, Massachusetts, 2036-2065 change from 1975-2004, Representative Concentration Pathways 4.5 and 8.5

This data release provides a set of Hydrological Simulation Program--Fortran (HSPF) model files representing 5 EPA-selected future climate change scenarios for the Upper Charles River Basin in Massachusetts. Output from these models are intended for use as input to EPA Watershed Management Optimization Support Tool (WMOST) modeling. Climate scenarios, based on 2036-2065 changes from 1975-2004 for

Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-2016

Water quality point measurements were collected by the US Geological Survey within the main channel Willamette River and its off-channel features in the summer and autumn of 2015 and 2016. All measurements include location, time, temperature, and depth below water surface, while most also include specific conductivity, dissolved oxygen, and pH.

Modified Land Cover Raster for the Upper Oconee Watershed

This dataset shows land cover in the Upper Oconee watershed. The data layer primarily uses the 2011 National Land Cover Database (NLCD) but was manually edited to include 2,219 additional reservoirs. The reservoirs were identified and digitized using 2010 National Aerial Imagery Program (NAIP) imagery.

Wabash River at Memorial Bridge, Vincennes, Indiana, Flood-Inundation Geospatial Data Sets and Metadata

Digital flood-inundation maps for a 10.2-mile reach of the Wabash River at Memorial Bridge at Vincennes, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Office of Community and Rural Affairs. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict es

Transient Electromagnetic Sounding Data Collected in the San Luis Valley, Colorado Near Great Sand Dunes National Park and Preserve and the Alamosa National Wildlife Preserve (Field Seasons 2007, 2009, and 2011)

Time-domain electromagnetic (TEM) soundings were made in the San Luis Valley, Colorado to map the location of a blue clay unit as well as suspected faults. A total of 147 soundings were made near and in Great Sand Dunes National Park and Preserve. An additional six soundings were made near Hansen Bluff on the eastern edge of the Alamosa National Wildlife Preserve. The blue clay is a significant hy

South Dakota Surface Water Data

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Wisconsin. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

South Dakota Water Quality Data

At selected surface-water and groundwater sites, the USGS maintains instruments that continuously record physical and chemical characteristics of the water including pH, specific conductance, temperature, dissolved oxygen, and percent dissolved-oxygen saturation. Supporting data such as air temperature and barometric pressure are also available at some sites.
