Natural gradient, lakebed tracer tests using nitrite in a nitrate-contaminated groundwater discharge zone in Ashumet Pond, Massachusetts
The U.S. Geological Survey Toxic Substances Hydrology Program at Cape Cod has been investigating the fate and transport of a treated-wastewater, groundwater contaminant plume. A portion of the contaminated groundwater discharges into Ashumet Pond, a kettle hole, freshwater lake. A study was conducted from June 2013 to June 2015 to document transport, transformation, and discharge of dissolved inor
Generalized regions of the Mississippi Alluvial Plain
As part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program study of the Mississippi Alluvial Plain (MAP), a shapefile representing seven generalized regions of the MAP extent as defined by Painter and Westerman (2018) was compiled. The generalized regions provide a framework for analysis, visualization, and regional comparisons of local data within the MAP. Regions nor
Least tern and piping plover responses to the 2011 Missouri River flood: Nest, chick, and adult datasets
This data release includes nest, chick, and adult survival data that were analyzed to evaluate effects of the 2011 Missouri River flood on endangered least terns and threatened piping plovers.
Phytoplankton, Microbial Source Tracking, and Metagenomics Data for Evaluation of Restoration Efforts at Urban Beaches on Southern and Western Lake Michigan, 2016-2018
The U.S. Geological Survey (USGS), in cooperation with the Great Lakes Restoration Initiative, collected data in 2017 to study the sources and occurrences of continual detections of high Escherichia coli (E. coli) detections at urban beaches along the Lake Michigan shoreline in northwest Indiana and northeastern Illinois. High E. coli detections cause the beaches to be closed for recreational use
Wetland Moist Soil Seed Maps for the Central Valley of California 2007-2017
We produced a series of maps of moist soil seed plants within managed wetlands in the Central Valley of California from 2007-2011 & 2013-2017. Moist soil seed plants, such as swamp timothy (Crypsis schoenoides) and watergrass (Echinochloa crusgallim), are a critical food source for migratory birds. Vegetation maps were created by classifying Landsat imagery from 2007-2011 and 2013-2017. A support
Coastal Bathymetry Data Collected in June 2018 from Fire Island, New York: Wilderness Breach and Shoreface
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, conducted a bathymetric survey of Fire Island, New York, from June 2 to 17, 2018. The U.S. Geological Survey is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the wilderness breach and the adjacent shoreface environment. During this stud
Geophysical data collected within and adjacent to the Little Wind River near Riverton, Wyoming
This data release contains geophysical data collected at the Little Wind River site near Riverton, Wyoming in 2015 and 2017. The dataset contains:[1] Fiber Optic Distributed Temperature Sensing data (FO-DTS, August-September 2015) collected in the water along the river bank, [2] Electrical Resistivity Tomography data (ERT, August 2017) collected on land near the river bank, and [3] Frequency domai
Groundwater arsenic data and ASCII grids for predicting elevated arsenic in northwestern and central Minnesota using boosted regression tree methods
This data release contains: (1) ASCII grids of predicted probability of elevated arsenic in groundwater for the Northwest and Central Minnesota regions, (2) input arsenic and predictive variable data used in model development and calculation of predictions, and (3) ASCII files used to predict the probability of elevated arsenic across the two study regions. The probability of elevated arsenic was
Surface water and bottom sediment chemical data and landscape variable input datasets for predicting the occurrence of chemicals of emerging concern in 25 U.S. river basins in the Great Lakes basin
This data release includes concentrations of contaminants of emerging concern (CEC), by chemical class, for sites sampled within 25 river basins in the U.S. portion of the Great Lakes basin and associated watershed characteristics. The CEC data include concentrations in surface water and sediment samples that were collected during 2010-2014. During the first 3 years, sample sites near mostly urban
USGS Surface-Water Data for New Jersey
Nationally, USGS surface-water data includes more than 850,000 station years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual field measurements at installations across the Nation.
USGS Groundwater Data for New Jersey
The Ground-Water database contains ground-water site inventory, ground-water level data, and water-quality data. Additional ground-water information for New Jersey is available at the New Jersey Water Science Center web page. This page includes geologic maps, a description of the aquifers in New Jersey, and references to selected ground-water reports.
USGS Water-Quality Data for New Jersey
At selected surface-water and ground-water sites, the USGS maintains instruments that continuously record physical and chemical characteristics of the water including pH, specific conductance, temperature, dissolved oxygen, turbidity, and percent dissolved-oxygen saturation. At sites where this information is transmitted automatically, data are available from the real-time data system.
