Mercury speciation and other constituent data for surface water and bed sediment associated with the Hamilton Airfield Wetland Restoration, Novato, California. USA
The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stage
Tabular data for selected items from the Census of Agriculture for the period 1950-2017 for counties in the conterminous United States
This product provides tabular data from the U.S. Department of Agriculture (USDA) Census of Agriculture for selected items for the period 1950-2017 for counties in the conterminous United States. Data from 1950-2012 are taken from LaMotte (2015) and 2017 data are retrieved from the USDA QuickStats online tool. Data which are withheld in the Census of Agriculture are filled with estimates
Datasets and scripts used for estimating streamflow and base flow within the nontidal Chesapeake Bay riverine system, water years 2006-15
This U.S. Geological Survey (USGS) data release contains estimated daily streamflow and base flow for HUC12 in the nontidal areas of the Chesapeake Bay watershed, monthly average streamflow and base flow, flow statistics, MATLAB scripts, and a document that describes how to create similar datasets in other watersheds. Daily streamflow was estimated for all the nontidal parts of the Ch
Twelve-digit hydrologic unit actual evapotranspiration and snowpack water equivalent storage from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System 1980-2016
This dataset is part of the National Water Census Water Budget Estimation and Evaluation Project's ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of actual evapotranspiration and snowpack water equivalent storage are added to the already released estimates of soil moisture, rech
Floating transient electromagnetic (FloaTEM) surveys in the Eel River near Falmouth, Massachusetts
Floating transient electromagnetic (FloaTEM) data were acquired on the Eel River during November 2018. During the survey, approximately 1.6 line-kilometers were collected in the Eel River, Falmouth, Massachusetts study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and New England Water Science Center. FloaTEM data acquired along the Eel
Towed transient electromagnetic (tTEM) surveys adjacent to the Tallahatchie River near Shellmound, Mississippi
Towed transient electromagnetic (tTEM) data were acquired adjacent to the Tallahatchie River during March 2018. During the survey, approximately 35 line-kilometers were collected in the Shellmound, Mississippi study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and the Aarhus University HydroGeophysics Group. FloaTEM data acquired near the
Floating and Towed Transient Electromagnetic Surveys used to Characterized hydrogeology underlying Rivers and Estuaries: March to December 2018
Surface and water-borne geophysical methods can provide information for the characterization of the subsurface structure of the earth for aquifer investigations. Floating and towed transient electromagnetic (FloaTEM and tTEM) surveys provide resistivity soundings of the subsurface, which can be related to lithology and hydrogeology. In the TEM method, electrical current is cycled through
Hyperspectral and RGB image data used to map salmon spawning locations on the American River, California, November 5-7, 2018
An unmanned aerial system (UAS) was used to acquire red/green/blue (RGB) and hyperspectral image data from the American River in California November 5-7, 2018, to support research on remote sensing of rivers, specifically mapping salmon spawning locations (redds) as part of an overall salmon habitat assessment program. The RGB images were acquired uisng a DJI MAtrice 210 equ
Salmon spawning locations (redds) mapped in the field along the American River, California, November 5-7, 2018
This data release includes images and field measurements used to map salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely sens
Floating transient electromagnetic (FloaTEM) surveys in the Tallahatchie River near Shellmound, Mississippi
Floating transient electromagnetic (FloaTEM) data were acquired on the Tallahatchie River during October 2018. During the survey, approximately 18.3 line-kilometers were collected in the Shellmound, Mississippi study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, Lower-Mississippi Gulf Science Center and the Aarhus University HydroGeophysic
Field measurements of water depth from the American River, California, November 5-7, 2018
Field measurements of water depth were acquired from a reach of the upper American River in California, November 5-7, 2018, to support research on mapping salmon spawning locations (redds) via remote sensing. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the wat
