Science Datasets
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Hydrogeochemical Mixing data from Lake Michigan Tributaries 2011
This dataset describes the hydrogeomorphic structure and lake-tributary mixing in three intermediate-sized Lake Michigan rivermouths: Ford River, Manitowoc River, and Pere Marquette River. Data were collected from May to October 2011. Water chemistry variables were measured with a multiparameter sonde along longitudinal, lateral, and vertical transects. Magnesium, boron, and stable
Hakalau Forest National Wildlife Refuge, Hawaii Akepa point-transect survey, 2002
This dataset contains the point-transect distance sampling records of Hawaii Akepa collected at Hakalau Forest National Wildlife Refuge in 2002, including survey point locations, distance to detected birds, number of detected birds, elevation, and alliance-level habitat classification. This data release consists of two tabular datasets, one that contains distances and the other that c
Electrical Resistivity Tomography in the Anza-Terwilliger Valley, Riverside County, California 2018
The Cahuilla Valley and Terwilliger Valley groundwater basins, 9-006 and 7-026 respectively (California Department of Water Resources 2016) located approximately 25 miles southwest of Palm Springs, are the sole-source for groundwater supply for the rural disadvantaged community and two Native American Tribes, the Ramona Band of Cahuilla and the Cahuilla. The characteristics and sustaina

Watershed Data Management (WDM) Database (SC18.WDM) for Salt Creek Streamflow Simulation, DuPage County, Illinois, January 1, 1997, through September 30, 2018
This data release is the update of the U.S. Geological Survey (USGS) - ScienceBase data release Bera (2019b), with the processed data for the period October 1, 2017, through September 30, 2018. This data release describes the watershed data management (WDM) database SC18.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data %
Total Mercury Concentrations in Smallmouth Bass from Chesapeake Bay Tributaries, USA Dataset, 2013-2017
This dataset includes fish scientific name, fish common name, site identification codes, latitude, longitude, site name, sample identification codes, collection date, tissue type, percent moisture content in fish samples, and wet and dry total mercury concentrations in fish tissues.
Adirondack New York soil chemistry data, 1992-2017
This dataset contains measurements of chemical concentrations of soil samples representing 28 headwater drainage basins completely within the Adirondack Park of New York State (ADK Park), one basin partially in the ADK Park, and one watershed 2 kilometers from the ADK Park boundary. Seven of these watersheds have been sampled 2 or 3 times over periods of 12 to 22 years. Soil samples wer
Statistical summaries of simulated groundwater residence times for the 10 regional aquifers of the Northern Atlantic Coastal Plain aquifer system, at a 1 square-mile grid resolution
Groundwater residence times were simulated for the major regional aquifers of the Northern Atlantic Coastal Plain aquifer system from New York to North Carolina using particle tracking in a regional groundwater flow model. Millions of particles were distributed throughout the aquifers of the North Atlantic Coastal Plain in a MODFLOW model with a volume-weighted algorithm, then tracked...
Watershed Data Management (WDM) Database (WBDR18.WDM) for West Branch DuPage River Streamflow Simulation, DuPage County, Illinois, January 1, 2007, through September 30, 2018

This data release describes the watershed data management (WDM) database file WBDR18.WDM. The WDM database file WBDR17.WDM (Bera, 2019b) is updated with the quality-assured and qu
Hurricane sedimentation in a subtropical salt marsh-mangrove community in the Mississippi River Delta Complex unaffected by vegetation type
Hurricanes periodically deliver sediment to coastal wetlands, such as those in the Mississippi River Delta Complex (MRDC), slowing elevation loss and improving resilience to sea-level rise. However, the amount of hurricane sediment deposited and retained in a wetland may vary depending on the dominant vegetation. In the subtropical climate of the MRDC, the black mangrove (Avicennia
