Airborne electromagnetic (AEM) and magnetic survey data were collected during July and August 2022 over a distance of 3,588.5 line kilometers covering Delaware Bay and surrounding regipons in New Jersey and Delaware. Data were collected as part of the USGS Delaware River Basin Next Generation Water Observing Systems (NGWOS) project to improve understanding of groundwater salinity distributions near Delaware Bay. The survey was primarily funded by the USGS, with partial support through collaboration with the University of Delaware to extend data collection to parts of Rehoboth Bay and Indian River Bay. Data were acquired by SkyTEM Canada Inc. with the SkyTEM 304M time-domain helicopter-borne electromagnetic system...

This USGS data release represents tabular data for a process to estimate net infiltration using a site-scale water-budget approach, Rainier Mesa, Nevada National Security Site, 2002-05. This dataset consists of the following: (1) Measured and corrected precipitation data from A12 weather station, Rainier Mesa, Nevada National Security Site, July 1, 2002 to June 30, 2005. (2) Inventory of net radiation, latent-heat flux, and sensible-heat flux gap-filled periods, pinyon-juniper evapotranspiration (ET) station, Rainier Mesa, Nevada National Security Site, January, 2002 to August, 2005. (3) Inventory of net radiation, latent-heat flux, and sensible-heat flux gap-filled periods, scrub-brush ET station, Rainier Mesa,...

These data represent the extent and spatial distribution of irrigated acreage delineated from maximum Normalized Difference Vegetation Index (NDVI) derived from Landsat scenes in the Walker River Basin, California and Nevada, at five-year intervals from 1975-2010. The field boundaries in this data set are digitized from one-year composite maximum NDVI data derived from atmospherically corrected Landsat 2 Multispectral Scanner (MSS), Landsat 5 MSS, and Landsat 5 Thematic Mapper (TM) scenes. NDVI was calculated from the corrected reflectance data for each selected scene during the growing season (May through early October) and a single, composite image of maximum NDVI values was derived for each 5-year interval. Selecting...

This USGS data release represents tabular data and water-level modeling files for the 16 Pahute Mesa multiple-well aquifer tests conducted from 2009–2014. The data release was produced in compliance with the new 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public. The dataset consists of 5 separate items: 1. Pumping time-series data (Tabular dataset) 2. Simplified pumping time-series data (Tabular dataset) 3. Drawdown time-series data (Tabular dataset) 4. Water-level models (Macro-enabled Excel spreadsheets) 5. SeriesSEE (Excel Add-In)

This USGS data release consists of two geospatial datasets. One dataset contains contours representing water levels based on depth-to-groundwater measurements made at 98 wells in July of 2012 in the Lahontan Valley near Fallon, NV. The second dataset contains contours representing water level change in the shallow aquifer in Lahontan Valley from 1992 - 2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013. These data support USGS Scientific Investigations Report 2016-5045 - Groundwater-Level Change and Evaluation of Simulated Water Levels for Irrigated Areas in Lahontan Valley, Churchill County, West-Central Nevada, 1992‒2012
