High-water marks in New Jersey following Hurricane Ida and associated floods, September 2021 High-water marks in New Jersey following Hurricane Ida and associated floods, September 2021
The data contained within include high-water marks collected at 50 sites throughout the regions of New Jersey affected by significant flooding from Hurricane Ida during September of 2021. Each site contains between one to six associated high-water marks that were documented, photographed, and surveyed to datum. The datum represented by the elevations of the high-water marks is the North...
Nitrogen sources to and export from the Chesapeake Bay watershed, 1950 to 2050 Nitrogen sources to and export from the Chesapeake Bay watershed, 1950 to 2050
This U.S. Geological Survey data release contains datasets that combine past data with future projections of nitrogen sources and nitrogen export to the Chesapeake Bay watershed for the years 1950-2050. To help understand the effect of human and environmental changes over this time period, data for nitrogen sources from wastewater, agricultural fertilizer and manure, and atmospheric...
Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed, 1950-2050 Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed, 1950-2050
Reactive nitrogen is transported from the atmosphere to the landscape as wet and dry deposition that contributes to annual nitrogen loads to the Chesapeake Bay. Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed during 1950 to 2050 are presented, and are based on field measurements, model simulations, statistical relations, and surrogate constituents...
Hydrogeologic Data for the Development of the Hydrogeologic Framework of the Coastal Lowlands Aquifer System Regional Groundwater Availability Study Area in Texas, Louisiana, Mississippi, Alabama, and Florida Hydrogeologic Data for the Development of the Hydrogeologic Framework of the Coastal Lowlands Aquifer System Regional Groundwater Availability Study Area in Texas, Louisiana, Mississippi, Alabama, and Florida
The U.S. Geological Survey (USGS) undertook a 5-year study beginning in 2016 to assess groundwater availability for the aquifers proximal to the Gulf of Mexico from the Texas-Mexico border to the western part of the panhandle of Florida; these aquifers are collectively referred to as the coastal lowlands aquifer system. This study is one of several regional groundwater availability...

Historical Produced Water Chemistry Data Compiled for the North Coles Levee Oilfield, Kern County, California Historical Produced Water Chemistry Data Compiled for the North Coles Levee Oilfield, Kern County, California
This dataset contains geochemical and other information for 40 historical samples of produced water from the North Coles Levee Oil Field. Three of these samples are from commingled tanks containing produced water from multiple wells as noted in the Remarks column. Water that is produced as a byproduct of oil production is called produced water. The numerical water chemistry data were...
