Data

The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On March 27, 1998, the USGS's NACCH project conducted an oblique

This dataset contains the trace element concentration results for samples collected from tapwater sites in East Chicago, Indiana, August-September, 2017, and Chicago, Illinois, July-December, 2017. Samples were collected one time, from 45 private residences and associated drinking water plants and source water locations. Water-quality samples were analyzed at two U.S. Geological Survey laboratorie

Chemical and biological concentration results, quality assurance and quality control and statistical summaries from 26 tapwater samples, collected from paired residential and work place sites in 11 states in 2016. Samples were analylzed at U.S. Geological Survey and U.S. Environmental Protection Agency laboratories.

As part of the Barrier Island Evolution Research Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey around the northern Chandeleur Islands, Louisiana, in August of 2017. The objective of the project is to improve the understanding of barrier island geomorphic evolution, particularly storm-related depo

This set of spatial data sets provides information pertaining to the known land use and disturbance history for lands within the March 2018 administrative boundaries of Agate Fossil Beds National Monument and Scotts Bluff National Monument in Nebraska; Badlands National Park and Wind Cave National Park in South Dakota; Little Bighorn Battlefield National Monument in Montana; and Devils Tower Natio

Data set containing test results of screening blood and serum samples from five populations of Brown Bears in Alaska. Samples were tested to detect current or previous exposure to bacteria (Brucella spp., Francisella tularensis, and Leptospira spp.), viruses (canine adenovirus, canine distemper virus, canine parvovirus, and influenza A virus), and parasites (Toxoplasma gondii, and Trichinella spp.

This USGS data release consists of three datasets representing three derived outlets or "pour points" for each 12-digit hydrologic unit (HU12) in the Watershed Boundary Dataset (WBD) snapshot delivered with NHDPlus V2.1. The three related pour point locations, each delivered in a stand-alone dataset, are: "from" (fpp) and "to" (tpp) points that identify the location where flow leaves the HU12 poly

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitor

A critical component of the Lake Michigan Diversion Accounting (LMDA) program, which oversees the diversion of Great Lakes water by the State of Illinois, is the U.S. Geological Survey (USGS) streamflow gaging station on the Chicago Sanitary and Ship Canal (CSSC) near Lemont, Illinois (05536890). The long-term application of an up-looking acoustic Doppler current profiler (ADCP) at this gaging sta

This data release of dune metrics for the Massachusetts coast is part of a 2018 update to the Massachusetts Shoreline Change Project. Because of continued coastal population growth and the increased threat of coastal erosion, the Massachusetts Office of Coastal Zone Management (CZM) launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. Maps of historic shoreli

This dataset provides analytical and other data in support of an analysis of lead and manganese in untreated drinking water from Atlantic and Gulf Coastal Plain aquifers, eastern United States. The occurrence of dissolved lead and manganese in sampled groundwater, prior to its distribution or treatment, is related to the potential presence of source minerals and specific environmental factors incl
