Airborne geophysical survey: Ashland HEM data

This report is a digital data release for a helicopter
electromagnetic and magnetic survey that was conducted during March
2007 in three 93-square-kilometer (36-square-mile) areas of eastern
Nebraska as part of a joint State of Nebraska and U.S. Geological
Survey study.  The objective of the survey is to improve the
understanding of the relationship between surface-water and ground-
water systems critical to developing water resource management
programs. The electromagnetic equipment consisted of six different
coil-pair orientations that measured electrical resistivity at
separate frequencies from about 400 hertz to about 115,000 hertz.
The electromagnetic data were converted to electrical resistivity
geo-referenced grids and maps, each representing different
approximate depths of investigation for each area.  The range of
subsurface investigation is comparable to the depth of shallow
aquifers. The three areas selected for the study, Ashland, Firth, and
Oakland, have glacial terrains and bedrock that typify different
hydrogeologic settings for surface water and ground water in eastern
Nebraska. The geophysical and hydrologic information from U.S.
Geological Survey studies are being used by resource managers to
develop ground-water resource plans for the area.

AA_Q26.TIF - Aleutian Arc U.S. EEZ GLORIA sidescan-sonar data mosaic (26 of 31) (LCC, 50 m, WGS84)

During late July through September 1987 and June and July 1988 the U.S. Geological Survey (USGS) conducted four cruises to cover the U.S. Exclusive Economic Zone (EEZ) region of the Aleutian Arc. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 31 digital mosaics of a 3 degree by 3 degree (or smaller) area with a 50-meter pixel resolution were completed for the region.

DS-777 Spatial Location the Model Cell Boundaries for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

This data set is one of many developed in support of The High Plains Groundwater Availability Project 
and the U.S. Geological Survey Data Series Report: Geodatabase Compilation of Hydrogeologic, 
Remote Sensing, and Water-Budget-Component data for the High Plains aquifer, 2011 (DS 777).
		
The creation of the model grid is an important first step in developing a groundwater-flow model, 
because all model inputs including properties, wells, and boundary conditions are assigned to 
the model cells. The northern High Plains groundwater-flow model boundary feature dataset 
contains three feature classes; the model grid cells for the northern High Plains groundwater-flow 
model in both polygon (cell) and point (centroid) format and the external boundary of the model. 
The model grid contains 449,175 cells, 565 rows and 795 columns. Each cell is 1,000 feet per 
side. The model grid is not rotated. The external boundary includes the active and inactive areas 
of the model.
		
The projection for the model grid and all feature classes in all geodatabases for this study are 
Albers Equal-Area Conic coordinate system, North American Datum1983.

Infiltration-excess overland flow estimated by TOPMODEL for the conterminous United States

This 5-kilometer resolution raster (grid) dataset for the conterminous United States represents the 
average percentage of infiltration-excess overland flow in total streamflow estimated by the watershed 
model TOPMODEL. Infiltration-excess overland flow is simulated in TOPMODEL as precipitation that 
exceeds the infiltration capacity of the soil and enters the stream channel.
		
TOPMODEL was applied to 5- by 5-kilometer areas across the conterminous United States using 
national climate, soils, and terrain geographic information system (GIS) datasets. The model was 
run for 1,000 days for each 5- by 5-kilometer area. The average percentage of infiltration-excess 
overland flow in total streamflow was computed for the 1,000-day simulation in each grid cell.

Sea Turtle Nesting Decision Points and Cross-Shore Beach Profile Data Collected on May 22, 2019, from Jensen Beach, Florida

On May 22, 2019, surveys were conducted on ‘high-density’ sea turtle nesting areas located on Jensen Beach, Florida. This dataset, Jensen_20190522.zip, was collected and processed by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and includes sea turtle nesting decision point locations (.csv) and cross-shore beach profiles (.xyz) at those locations. Utilizing previously published methods for collecting beach profile data (Henderson and others, 2016; Brown and others, 2018), data were acquired by USGS scientists walking along cross-shore transect lines while carrying a survey backpack that was equipped with a Global Navigation Satellite System (GNSS) receiver and GNSS antenna. The horizontal position data are provided in the Universal Transverse Mercator (UTM) coordinate system, Zone 17 North (17N), referenced to the North American Datum of 1983 (NAD83), and the elevation data are referenced to the North American Vertical Datum of 1988 (NAVD88), GEOID12B.

Umpqua River Oregon Active Channel 2000

The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing 
into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District of the U.S. Army 
Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage along the downstream alluvial reaches 
of the North and South Umpqua Rivers and the entire mainstem Umpqua River. This includes the lower 46.8 kilometers 
(29.1 miles) of the North Umpqua River and the lower 122.6 kilometers (76.2 miles) of the South Umpqua River. 
	 
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical channel change 
and estimation of a sediment budget. To support these analyses, digital channel maps were produced to depict channel and 
floodplain conditions along the Umpqua River system from different time periods.
		
GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 1939, 1967, and 2005. 
For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem Umpqua River downstream from the confluence 
of the North and South Umpqua Rivers, GIS layers were also developed for the time periods 1994, 2000, and 2009.
		
For this project, the active channel was defined as area typically inundated during annual high flows, and includes the low-flow 
channel as well as side channels, islands, and channel-flanking gravel bars. The active channel datasets were developed by 
digitizing from aerial photographs. Aerial photographs from 1939 and 1967 were scanned, rectified, and mosaiced for this 
project. Digital orthophotographs from 1994, 2000, 2005, and 2009 are publicly available (See metadata for each photograph 
set for more information on the rectification process and resolution of each dataset). Although our study area encompasses 
the Umpqua River and lower reaches of the North and South Umpqua Rivers, the extent of each dataset depended upon the 
underlying aerial photographs; for example, the 1967 photographs extend only as far downstream as floodplain kilometer 7, 
whereas the 1939 and 2005 datasets extend to the mouth of the Umpqua River at the Pacific Ocean.

EAARL Coastal Topography–Northwest Florida, Post-Hurricane Katrina, 2005: First Surface

ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey (USGS). Elevation measurements were collected over northwest Florida, post-Hurricane Katrina (August 2005 hurricane), using the National Aeronautics and Space Administration (NASA) Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 60 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point spacing of 2-3 meters. The EAARL, developed originally by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 3 centimeters. A sampling rate of 3 kilohertz or higher results in an extremely dense spatial elevation dataset. Over 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

Grey Toned Surface Model Image from the 150 meter grid of the Puerto Rico Trench (gtsurfmod.tif)

The Puerto Rico Trench is a tectonic plate boundary where the North American Plate slides by and descends under the Caribbean Plate.  Although much of the trench lies within the United States of America's Exclusive Economic Zone (EEZ), surprisingly few surveys have been conducted there during the past 25 years.  This data set is a grey toned surface model mosaic derived from the 150 meter grid made from the multibeam bathymetric data collected during the U.S. Geological Survey (USGS) science cruise 03008 in collaboration with National Oceanic and Atmospheric Administration (NOAA) Research Cruise RB0303 from 18 February to 7 March 2003, Leg II of III.

Nutrient Impaired 303(d) Streams for the Pacific Northwest

Under section 303(d) of the 1972 Clean Water Act, states, territories, and authorized tribes are required to 
develop lists of impaired waters. These impaired waters do not meet water quality standards that states, 
territories, and authorized tribes have set for them, even after point sources of pollution have installed the 
minimum required levels of pollution control technology. The law requires that these jurisdictions establish 
priority rankings for waters on the lists and develop TMDLs for these waters” (U.S. Environmental Protection 
Agency, 2011). Waterways represented in this data set are a subset of these EPA 303 (d) listed streams 
that were classified as nutrient impaired. Nutrient impaired streams include those listed for nutrients, 
agriculture, crop sources, pH, dissolved oxygen, chlorophyll a, nitrate, phosphorus, and nitrogen. Total 
phosphorus and total nitrogen values attributed to stream reaches are based on EPA Level III Ecoregions 
aggregations for the National Nutrient Strategy values (U.S. Environmental Protection Agency, 2000). 
Values are based on 25th percentiles for aggregate nutrient reference conditions for both phosphorus 
and nitrogen. Data relate to a 2002 time period, with data collected from each of the state agencies 
as close to that period as possible. See processing steps for more detail on individual state data sets 
and time periods.

Point Shapefile of Interpreted Lowstand Horizon Based on Seismic-Reflection Profiles Collected in Apalachicola Bay in 2006 from U.S. Geological Survey Cruise 06001 (LOWSTAND_GEOG.SHP, Geographic, WGS84)

Apalachicola Bay and St. George Sound contain the largest oyster fishery in Florida, and the growth and distribution of the numerous oyster reefs here are the combined product of modern estuarine conditions and the late Holocene evolution of the bay. A suite of geophysical data and cores were collected during a cooperative study by the U.S. Geological Survey, the National Oceanic and Atmospheric Administration Coastal Services Center, and the Apalachicola National Estuarine Research Reserve to refine the geology of the bay floor as well as the bay's Holocene stratigraphy. Sidescan-sonar imagery, bathymetry, high-resolution seismic profiles, and cores show that oyster reefs occupy the crests of sandy shoals that range from 1 to 7 kilometers in length, while most of the remainder of the bay floor is covered by mud. The sandy shoals are the surficial expression of broader sand deposits associated with deltas that advanced southward into the bay between 6,400 and 4,400 years before present. The seismic and core data indicate that the extent of oyster reefs was greatest between 2,400 and 1,200 years before present and has decreased since then due to the continued input of mud to the bay by the Apalachicola River. The association of oyster reefs with the middle to late Holocene sandy delta deposits indicates that the present distribution of oyster beds is controlled in part by the geologic evolution of the estuary.

MODFLOW-2005, MODPATH, and MOC3D used for groundwater flow simulation, pathlines analysis, and solute transport in the crystalline-rock aquifer in the vicinity of the Savage Municipal Water-Supply Well Superfund Site, Milford, New Hampshire

The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency and
the New Hampshire Department of Environmental Services, developed a model for used with 
MODFLOW-2005 and MODPATH5 to evaluate groundwater flow and advective transport under
pre- and post-remediation conditions in the crystalline-rock aquifer in the vicinity of the Savage
Municipal Water-Supply Well Superfund site Milford, New Hampshire. In addition, a previously
developed model (https://doi.org/10.3133/sir20045176 and https://doi.org/10.3133/ofr20121079)
was used with MOC3D to evaluate the solute-transport of tetrachloroethylene (PCE). In 2010 
PCE, a chlorinated volatile organic compound, was detected in groundwater from monitoring 
wells tapping the deep (more than 300 feet below land surface) fractures in a crystalline-rock 
aquifer. The crystalline-rock aquifer underlies the Milford-Souhegan glacial-drift (MSGD) aquifer
(a high water-producing aquifer) and the Savage Municipal Water-Supply Well Superfund site. 
Residential water-supply wells are within one-quarter of a mile of the PCE-contaminated 
monitoring wells and many are likely installed in similar rock types and formations as those of
the monitoring wells. The need to understand and quantify flow and transport in the crystalline-
rock aquifer is crucial in assessing strategies for remediation. The current, area-wide model 
simulates flow in the crystalline-rock aquifer and covers a much larger area than previous models
with the goal of improving the computation of groundwater flow from distal locations to the 
residential wells and the area. This USGS data release contains all of the input and output files
 for the simulations described in the associated model documentation report 
(https://doi.org/10.3133/sir20205137).
