Baseline_BackBarrier.shp - Baseline Along the Back-Barrier (North-Facing) Coast of Dauphin Island, Alabama, Generated to Calculate Shoreline Change Rates.


Analysis of shoreline change for Dauphin Island, Alabama was conducted using the U.S. Geological Survey (USGS) Digital Shoreline Analysis System (DSAS) v.4.3 for ArcMap (Thieler and others, 2009) and vector shorelines derived from air photos and lidar elevation surveys. DSAS-generated transects were cast at 100-meter intervals along a user defined shore-parallel baseline. The intersections of transects with the mean high water (MHW) shoreline positions are identified by intercept points. The rate of shoreline change was determined by measuring the differences in the distance to each historical shoreline position from the baseline along each transect.

Three analyses of change rates were conducted using a combination of shorelines derived from different data sources. Shoreline change rates from the wet dry line (WDL) shoreline were derived from 10 sets of air photos from 1940 - 2015. Rates of change were also calculated using MHW shorelines extracted from 14 lidar datasets from 1998 - 2014. A final change analysis was conducted using a combination of all WDL (aerial) and MHW (lidar) shorelines, from 1940 - 2015.

Digital Shoreline Analysis System version 4.3 shoreline intersection points used to calculate long-term shoreline change statistics excluding the 1970-1979 and 1994 shorelines within the South Cape Cod coastal region from Stage Harbor Light in Chatham to Nobska Point in Woods Hole (SouthCapeCod_intersects_LTwo.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km in total length) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).

Structure-from-Motion bathymetric maps from the Florida Keys, 2019

Structure-from-Motion (SfM) bathymetric maps were created using seafloor images collected using the new 5-camera system SfM Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). Images were collected during July 2019 by towing the SQUID-5 in 3 to 4 meters of water off of Islamorada in the Florida Keys during 3 days. The five cameras were synchronized together and with a survey-grade Global Positioning System (GPS). Images were collected over diverse benthic settings, including living and senile reefs, rubble, and sand. Bathymetric maps were created from the photos using SfM photogrammetric software.

Gamma spectroscopy data for box core sediments collected from Barnegat Bay, New Jersey in May 2014 (U.S. Geological Survey Field Activity Number 2014-310-FA)

Barnegat Bay, located along the eastern shore of New Jersey, was significantly impacted by Hurricane Sandy in October 2012. Scientists from the U.S. Geological Survey (USGS) developed a multidisciplinary study of sediment transport and hydrodynamics to understand the mechanisms that govern estuarine and wetland responses to storm forcing.  This report details the physical and chemical characteristics of surficial and downcore sediments from two areas within the bay. Eleven sites were sampled in both the central portion of the bay near Barnegat Inlet and in the southern portion of the bay in Little Egg Harbor. Laboratory analyses include Be-7, Pb-210, bulk density, porosity, x-radiographs, and grain-size distribution. These data will serve as a critical baseline dataset for understanding the current sedimentological regime and can be applied to future storms for understanding estuarine and wetland evolution. This report serves as an archive for sedimentological and radiochemical data derived from the surface sediments and box cores. Downloadable data are available as Excel spreadsheets, PDF files, and JPEG files, and includes sediment core data plots and x-radiographs, as well as, physical-properties, grain-size, alpha-spectoscopy, and gamma-spectroscopy data. Federal Geographic Data Committee metadata are available for analytical datasets in the data downloads page of this report.

Combined Thickness of the Modeled Saddle Mountains Basalt and Mabton Interbed Geomodel Units (smthk_f)

The smthk_f grid represents the modeled combined thickness of the Saddle Mountains Basalt 
and Mabton interbed geomodel units at a 500 foot resolution. It is one grid of a geomodel that 
consists of eleven grids and a spatial extent polygon shapefile. As part of a U.S. Geological 
Survey Groundwater Resources Program study, a three-dimensional geomodel was constructed 
for approximately 53,000 mi2 of the Columbia Plateau in Washington, Oregon, and Idaho. This 
geomodel was constructed to define the general aquifer system geometry for use in a regional 
numerical groundwater flow model. Simplifications and assumptions consistent with this ultimate 
goal and the uncertainty in the available data were made. The geomodel units consist of Miocene 
age Columbia River Basalt Group strata and younger alluvial overburden covering approximately 
44,000 mi2. Data were compiled from numerous databases and detailed studies completed 
during the past three decades. These data include stratigraphic interpretations made on more 
than 13,000 wells and a contiguous compilation of surficial geology and structural features 
spanning the study area. These data were simplified and used to construct piecewise-smooth 
trend surfaces that represent upper and lower subsurface geomodel unit boundaries in this 
complex folded and faulted terrain.  The smoothness of the surfaces implicitly represents 
uncertainty in prediction of each surface resulting from data gaps, errors in borehole interpretations, 
errors in mapped contact locations, and uncertainty in the shape of the paleo-surface upon which 
flood basalts were emplaced. Using a rule-based algorithm, surfaces were then recombined to 
construct a fully three-dimensional model with a 500-foot grid resolution that is consistent with 
the data and for which error estimates may be made. The modeling process yielded improved 
estimates of unit volumes, refinement of location of large structural features, and identification 
of features that may be important for ongoing groundwater studies.

Historical boundary of the Death Valley regional ground-water flow system by Harrill and Prudic (1998), for the Death Valley regional ground-water flow system study, Nevada and California

This digital data set is a historical definition of the extent (approximately 42,600 square-kilometers) 
and lateral boundary of the Death Valley regional ground-water flow system (modified from Harrill and 
others, 1988; and Harrill and Prudic, 1998). Harrill and others (1988) developed boundaries for the 
major ground-water flow systems in the Great Basin region of Nevada, Utah, and adjacent states 
using the boundaries of hydrographic areas.  Harrill and Prudic (1998) refined the delineation of the 
Death Valley ground-water flow system by using a more accurate base map.  The studies by Harrill 
and others (1988) and Harrill and Prudic (1998) served as historical references used to support 
development of the transient ground-water model of Death Valley regional ground-water flow system 
(DVRFS) completed in 2004 by the USGS (see "Larger Work Citation", Chapter A, pages 9-10, for 
details).

Sea Turtle Nesting Decision Points and Cross-Shore Beach Profile Data Collected on July 21, 2021, from Melbourne Beach, Florida

On July 21, 2021, surveys were conducted on ‘high-density’ sea turtle nesting areas located on Melbourne Beach, Florida. This dataset, Melbourne_20210721.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.

Storm-Impact Scenario XBeach Model Results – Scenario 20 Digital Elevation Model (DEM) Grid

The numerical model XBeach (version 4937) was used to investigate how different storm scenarios impact the sediment berm constructed offshore of the Chandeleur Islands and adjacent areas. The XBeach model solves coupled 2-dimensional, horizontal wave propagation equations to predict flow, sediment transport, and bottom changes for varying spectral wave and flow boundary conditions (Roelvink and others, 2009 ). The XBeach model setup requires the input of a merged topographic and bathymetric DEM, and inputs of wave spectra (based on significant wave height, peak wave period, and wave direction) and water level (tide and surge) time series at the seaward model boundary that span the duration of each storm bin. The Xbeach model input and output of topography and bathymetry resulting from simulation of storm-impact scenarios at the Chandeleur Islands, LA, as described in USGS Open-File Report 2017–1009 are provided via a USGS data release (storm scenario bins where no events were observed are excluded). For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Mickey and others (2017).

Radon-222 and Water Column Data Related to Submarine Groundwater Discharge Along the Western Margin of Indian River Lagoon, Florida—September 2016 to July 2017 (ver. 2.0, March 2018)

Indian River Lagoon (IRL) is one of the most biologically diverse estuarine systems in the continental United States, stretching 200 kilometers (km) along the Atlantic coast of central Florida. The width of the lagoon varies between 0.5-9.0 km and is characterized by shallow, brackish waters with significant human development along both shores.
Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center, working in collaboration with the St. Johns River Water Management District, mapped surface water radon-222 (radon in water) and basic physical water column properties (for example, salinity and temperature) to investigate submarine groundwater discharge at two locations, Eau Gallie North and Riverwalk Park, along the western shore of IRL. Eau Gallie North is near the central section of IRL. Riverwalk Park is approximately 20 km north of Eau Gallie site. At each study site, the radon mapping surveys were performed over seven north–south shore parallel transects (EA–EG and RA–RG, respectively), situated between 75–1000 meters offshore, and approximately 1.5 km in length. Each transect was mapped three times in an alternating north–south direction. Surface water was continuously pumped on-board into an air-water exchanger; dissolved radon-222 was purged from the water into a gaseous phase inside the exchanger. Radon-222 in the exchanger was continuously pumped into and measured by commercially available radon-in-air detectors (RAD7, Durridge, Inc.). In situ surface water temperature and salinity, as well as the water temperature in the exchanger, were also measured.  Radon in air measurements were corrected to radon in water activities using the temperature-salinity dependent air-water partitioning coefficient (Schubert and others, 2012). Starting in September 2016, surveys were conducted bimonthly along the same transects to determine seasonal and temporal variability of radon-222. This data release contains the raw radon-222 data, physical water column data, Esri GIS data files and data distribution maps of the radon-222 activity and surface water salinity collected from September 2016 through July 2017.

Acquisition and observation logs for seabed video and sediment samples from Stellwagen Bank during U.S. Geological Survey field activity 2016-004-FA, aboard the R/V Auk, January 28, 2016

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 19 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Klamath Basin Water Rights Place of Use

The Klamath Basin Restoration Agreement (KBRA) was developed by a diverse group of stakeholders, 
Federal and State resource management agencies, Tribal representatives, and interest groups to provide 
a comprehensive solution to ecological and water-supply issues in the Klamath Basin. The Off-Project 
Water Program (OPWP), one component of the KBRA, has as one of its purposes to permanently provide 
an additional 30,000 acre-feet of water per year on an average annual basis to Upper Klamath Lake through 
“voluntary retirement of water rights or water uses or other means as agreed to by the Klamath Tribes, to 
improve fisheries habitat and also provide for stability of irrigation water deliveries.” The geographic area 
where the water rights could be retired encompasses approximately 1,900 square miles. The OPWP area 
is defined as including the Sprague River drainage, the Sycan River drainage downstream of Sycan Marsh, 
the Wood River drainage, and the Williamson River drainage from Kirk Reef at the southern end of Klamath 
Marsh downstream to the confluence with the Sprague River. Extensive, broad, flat, poorly drained uplands, 
valleys, and wetlands characterize much of the study area. Irrigation is almost entirely used for pasture.
    To assist parties involved with decisionmaking and implementation of the OPWP, the U.S. Geological 
Survey (USGS), in cooperation with the Klamath Tribes and other stakeholders, created five hydrological 
information products. These products include GIS digital maps and datasets containing spatial information 
on evapotranspiration, subirrigation indicators, water rights, subbasin streamflow statistics, and return-flow 
indicators.
