Transects with net change results for GPS and Worldview shorelines for the Grand Bay National Estuarine Research Reserve in Mississippi from 2013-2020

Shoreline change analysis is an important environmental monitoring tool for evaluating coastal exposure to erosion hazards, particularly for vulnerable habitats such as coastal wetlands where habitat loss is problematic world-wide. The increasing availability of high-resolution satellite imagery and emerging developments in analysis techniques support the implementation of these data into coastal management, including shoreline monitoring and change analysis. Geospatial shoreline data were created from a semi-automated methodology using WorldView (WV) satellite data between 2013 and 2020. The data were compared to contemporaneous field-surveyed Real-time Kinematic (RTK) Global Positioning System (GPS) data collected by the Grand Bay National Estuarine Research Reserve (GBNERR) and digitized shorelines from U.S. Department of Agriculture National Agriculture Imagery Program (NAIP) orthophotos. Field data for shoreline monitoring sites was also collected to aid interpretation of results. This data release contains digital vector shorelines, shoreline change calculations for all three remote sensing data sets, and field surveyed data. The data will aid managers and decision-makers in the adoption of high-resolution satellite imagery into shoreline monitoring activities, which will increase the spatial scale of shoreline change monitoring, provide rapid response to evaluate impacts of coastal erosion, and reduce cost of labor-intensive practices. For further information regarding data collection and/or processing methods, refer to the associated journal article (Smith and others, 2021).

Trackline navigation for multi-channel seismic data collected by the U.S. Geological Survey on U.S. Atlantic Seaboard in 2014 (Geographic, WGS84,  polyline shapefile 2014-011-FA_seistrk.shp)

In summer 2014, the U.S. Geological Survey conducted a 21-day geophysical program in deep water along the Atlantic continental margin by using R/V Marcus G. Langseth (Field Activity Number 2014-011-FA). The purpose of the seismic program was to collect multichannel seismic reflection and refraction data to determine sediment thickness. These data enable the United States to delineate its Extended Continental Shelf (ECS) along the Atlantic margin. The same data can also be used to understand large submarine landslides and therefore assess their potential tsunami hazard for infrastructure and communities living along the eastern seaboard. Supporting geophysical data were collected as marine magnetic data, gravity data, 3.5-kilohertz shallow seismic reflections, multibeam echo sounder bathymetry, and multibeam backscatter. 
The survey was conducted from water depths of approximately 1,500 meters to abyssal seafloor depths greater than 5,000 meters. Approximately 2,761 kilometers of multi-channel seismic data was collected along with 30 sonobuoy profiles.
This field program had two primary objectives: (1) to collect some of the data necessary to establish the outer limits of the U.S. Continental Shelf, or Extended Continental Shelf, as defined by Article 76 of the United Nations Convention of the Law of the Sea and (2) to study the sudden mass transport of sediments down the continental margin as submarine landslides that pose potential tsunamigenic hazards to the Atlantic and Caribbean coastal communities.
More information regarding the field activity can be found in the cruise report:

FTLOADDS (combined SWIFT2D surface-water model and SEAWAT groundwater model) simulator used to assess proposed sea-level rise response and water-resource management plans for the hydrologic system of the South Florida Peninsula for the Biscayne and Southern Everglades Coastal Transport (BISECT) Model

The Biscayne and Southern Everglades Coastal Transport(BISECT) 
model combines a three-dimensional groundwater model with a two-
dimensional hydrodynamic surface-water model with variable-density 
solute-transport. BISECT was constructed by combining two existing 
models, Tides and Inflows to the Mangrove Everglades (TIME) 
(https://doi.org/10.3133/sir20075010), and Biscayne 
(https://doi.org/10.3133/sir20125099), and modifying the Flow and 
Transport in a Linked Overland/Aquifer Density-Dependent System 
(FTLOADDS) simulator (https://doi.org/10.1016/j.jhydrol.2005.04.015) 
to include spatially variations in the solar radiation reflected back into 
the atmosphere from the Earth’s surface (albedo) to improve model 
results. Input data files, containing parameters and boundary condtions 
for groundwater and surface-water, were developed for the calibrated 
model, representing conditions from 1996 to 2004. Input data scenarios 
were developed by altering the relevent parameters to represent the 
likely effects of 
1) different depth aquifer barriers, 
2) possible future changes to current 
water-management practices, and 
3) two values of sea-level rise. 
Output files indicate the effects of these input on surface-water stages 
and flows, hydroperiod, and groundwater levels and salinity. Additional 
input and output files for the model was tested for sensitivity by 
perturbing the parameters for frictional resistance, wind forcing, 
tidal amplitude, thickness of surfical transistion layer, conductance 
of canal beds, vertical and horizontal aquifer conductance, and 
albedo. 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/SIR20195045). This 
data release also includes (1) postprocessing Fortran scripts and 
associated input data files for the sensitivity and scenarios runs, 
(2) the FTLOADDS source code.

Digital data sets that describe aquifer characteristics of the Rush Springs aquifer in western Oklahoma

This data set consists of digitized water-level elevation
contours for the Rush Springs aquifer in western
Oklahoma. This area encompasses all or part of Blaine, Caddo,
Canadian, Comanche, Custer, Dewey, Grady, Stephens, and
Washita Counties. The water-level elevation data set was
created to be used as input into a computer model to simulate
the ground-water flow in the Rush Springs aquifer. In the
ground-water flow model, Mark F. Becker (U.S. Geological
Survey, written commun., 1997) defined the Rush Springs
aquifer to include the Rush Springs Formation, alluvial and
terrace deposits along major streams, and parts of the Marlow
Formations, particularly in the eastern part of the aquifer
boundary area.
The Permian-age Rush Springs Formation consists of highly
cross-bedded sandstone with some interbedded dolomite and
gypsum. The Rush Springs Formation is overlain by
Quaternary-age alluvial and terrace deposits that consist of
unconsolidated clay, silt, sand, and gravel. The Rush Springs
Formation is underlain by the Permian-age Marlow Formation
that consists of interbedded sandstones, siltstones,
mudstones, gypsum-anhydrite, and dolomite beds. The parts of
the Marlow Formation that have high permeability and porosity
are where the Marlow Formation is included as part of the
Rush Springs aquifer (Mark F. Becker, written commun.,
1997).
The Rush Springs aquifer underlies about 2,400 square miles
of western Oklahoma and is an important source of water for
irrigation, livestock, industrial, municipal, and domestic
use. Irrigation wells are reported to have well yields
greater than 1,000 gallons per minute (Mark F. Becker,
written commun., 1997).
The water-level elevation data set was prepared at a scale of
1:250,000 by Mark F. Becker (written commun., 1997) from
water levels measured in wells prior to the year 1950 that
represented "pre-development" water-level conditions.
Pre-development is a term used to indicate a time
before many irrigation wells were constructed in the Rush
Springs aquifer. The digital data set contains water-level
elevations that range from 1,200 to 1,850 feet above sea
level or the National Geodetic Vertical Datum of 1929
(NGVD29) (Mark F. Becker, written commun., 1997).

1-Meter Sample Resolution Interferometric Swath Backscatter Data Collected in 2012 from the Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Number 12BIM03)

As part of the Barrier Island Evolution Research Project, scientists from the U.S. Geological Survey's St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys off the northern Chandeleur Islands, Louisiana, in June of 2012. The overall objective of the study is to better understand barrier-island geomorphic evolution, particularly storm-related depositional and erosional processes that shape the islands over annual to interannual timescales (1-5 years). The collection of geophysical data will allow us to identify relationships between the geologic history of the island and its present day morphology and sediment distribution. This mapping effort was the first in a series of three planned surveys in this area. High resolution geophysical data collected in each of 3 consecutive years along this rapidly changing barrier-island system will provide a unique time-series dataset that will significantly further the analyses and geomorphological interpretations of this and other coastal systems, improving our understanding of coastal response and evolution over short time scales (1-5 years). This report serves as an archive of processed interferometric swath and single-beam bathymetry data that were collected during two cruises (USGS Field Activity Numbers 12BIM03 and 12BIM04) along the northern portion of the Chandeleur Islands, Breton National Wildlife Refuge, Louisiana in July of 2012. Geographic information system data products include a 50 m-cell-size interpolated bathymetry grid surface, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata.

Archive of Digitized Analog Boomer and Minisparker Seismic Reflection Data Collected from the Alabama-Mississippi-Louisiana Shelf During Cruises Onboard the R/V Carancahua and R/V Gyre, April and July, 1981

In April and July of 1981, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework of the Alabama-Mississippi-Louisiana Shelf in the northern Gulf of Mexico. Work was conducted onboard the Texas A&amp;M University R/V Carancahua and the R/V Gyre to develop a geologic understanding of the study area and to locate potential hazards related to offshore oil and gas production. While the R/V Carancahua only collected boomer data, the R/V Gyre used a 400-Joule minisparker, 3.5-kilohertz (kHz) subbottom profiler, 12-kHz precision depth recorder, and two air guns. The authors selected the minisparker data set because, unlike with the boomer data, it provided the most complete record. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS). This report serves as an archive of high-resolution scanned Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) images of the original boomer and minisparker paper records, navigation files, trackline maps, Geographic Information System (GIS) files, cruise logs, and formal Federal Geographic Data Committee (FGDC) metadata.

MODFLOW-NWT model used for the simulation of the Cimarron River Alluvial Aquifer in the Pawnee Nation jurisdictional area in Payne County, OK, 2016-17

A three-dimensional, finite-difference MODFLOW 2005 groundwater model using the 
Newton formulation solver (MODFLOW-NWT) was created for the Cimarron River 
alluvial aquifer in Payne County, north-central Oklahoma to assess the impacts of 
current groundwater withdrawal rates with respect to current and future groundwater 
availability and the impacts to baseflow to the Cimarron River. To better understand 
current (2021) water resources and possible future water availability in the Pawnee 
Nation Tribal jurisdictional area, the U.S. Geological Survey, in cooperation with the 
Bureau of Indian Affairs and the Pawnee Nation of Oklahoma, compiled available 
hydrogeologic data and developed conceptual and numerical groundwater-flow models. 
The numerical model consists of a single layer representing alluvium and terrace 
deposits within the alluvial aquifer model area. The calibrated model contains one 
steady-state stress period and 24 monthly, transient stress periods for 2016-17. 
Streamflow-capture analysis was applied to the steady-state simulation to identify 
areas of the aquifer where base flows in the Cimarron River were most sensitive to 
groundwater withdrawals. 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/sir20215073).
