Radon-222 Time-Series Data Related to Submarine Groundwater Discharge Along the Western Margin of Indian River Lagoon, Florida

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, collected time-series of surface water radon-222 (radon-in-water) during two sampling periods in 2017 to investigate submarine groundwater discharge at Indian River Lagoon (IRL). Time-series radon data were collected at two sites, Eau Gallie North and Riverwalk Park, along the western shore of IRL. Eau Gallie North (EGN) is near the central section of IRL while Riverwalk Park (RWP) is approximately 20 km north of the Eau Gallie site. Stationary instrument moorings were deployed concurrently with continuous radon surface water mapping along shore-parallel transects conducted by the U.S. Geological Survey in May, September and November surveys outlined in previously published data releases (https://doi.org/10.5066/F7QF8S05 and https://doi.org/10.5066/F76Q1WG4). At each of the two study sites, a nearshore mooring (~10 meters (m) from shore) and an offshore mooring (~80-120 m from shore) were deployed to collect time-series of surface water radon-222 for six days. Surface water was continuously pumped into an air-water exchanger, where 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 a commercially available radon-in-air detector (RAD7, Durridge, Inc). Water temperatures in the exchanger, as well as water level and conductivity, were measured every 5 minutes. Radon-in-air measurements were corrected to radon-in-water activities using the temperature-salinity dependent air-water partitioning coefficient (Schubert and others, 2012). This data release contains the radon-222 time-series data, water temperature, conductivity, salinity and water level data collected during the mooring deployments of the May 2017, September 2017, and November 2017 surveys.

Estuarine Shoreline and Barrier-Island Sandline Change Assessment Dataset

The Barrier Island and Estuarine Wetland Physical Change Assessment Dataset was created to calibrate and test probability models of barrier island sandline and estuarine shoreline change for study areas in Virginia, Maryland, and New Jersey. The models examined the influence of hydrologic and physical variables related to storm-derived overwash and estuarine shoreline change. Variables were calculated using a transect-based method in a geographic information system (GIS) by creating shoreline-perpendicular lines at regular intervals along the oceanfront shoreline and extrapolating the features from geospatial data, including lidar, bathymetry and aerial imagery. In addition, the dataset provides storm-derived barrier island change for Hurricane Sandy, as well as linear rates of change for long-term sandline and estuarine shorelines.

1-meter sidescan-sonar mosaic image collected by the U.S. Geological Survey along the Delmarva Peninsula, MD and VA in 2014 (GeoTIFF, UTM Zone 18N, WGS 84)

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A U.S. Geological Survey cruise was conducted in the summer of 2014 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Data collected during the 2014 cruise include swath bathymetry, sidescan sonar, chirp and boomer seismic-reflection profiles, acoustic Doppler current profiler, and sample and bottom photograph data. Processed data in raster and vector format are released here for the swath bathymetry, sidescan sonar, and seismic-reflection profiles.  More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/ and https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA

Digital map of hydraulic conductivity for the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

This digital data set consists of hydraulic conductivity
contours and polygons for the High Plains aquifer in the central
United States.  The High Plains aquifer extends from south of 32
degrees to almost 44 degrees north latitude and from 96 degrees
30 minutes to almost 106 degrees west longitude.  The outcrop
area covers 174,000 square miles and is present in Colorado,
Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and
Wyoming.
		
This digital data set was created by digitizing the hydraulic
conductivity contours from a 1:1,000,000 base map created by the
U.S. Geological Survey High Plains Regional Aquifer-System
Analysis (RASA) project (Gutentag, E.D., Heimes, F.J., Krothe,
N.C., Luckey, R.R., and Weeks, J.B., 1984, Geohydrology of the
High Plains aquifer in parts of Colorado, Kansas, Nebraska, New

Satellite-derived shorelines for the U.S. Atlantic coast (1984-2021)

This dataset contains shoreline positions derived from available Landsat satellite imagery for five states (Delaware, Maryland, Viginia, Georgia, and Florida) along the U.S. Atlantic coast for the time period 1984 to 2021. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are presented in KMZ format. Significant uncertainty is associated with the locations of shorelines in extremely dynamic regions, including at the locations of river mouths, tidal inlets, capes, and ends of spits. These data are readily viewable in Google Earth. For best display of results, it is recommended to turn off any 3D viewing. For technical users and researchers, data can be ingested into Global Mapper or QGIS for more detailed analysis. Similar shoreline positions for North Carolina and South Carolina are available from Barnard and others, 2023 at https://doi.org/10.5066/P9W91314.

Knudsen 3202 seismic-reflection data trackline navigation collected by the USGS within Red Brook Harbor, MA, 2009 (RB_SeismicTrackline)

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/). This is the spatial dataset for the Red Brook Harbor survey area within Buzzards Bay, Massachusetts.  These data are the results of a high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples and bottom photographs) survey, conducted in 2009.
In addition to inclusion within the USGS-CZM geologic mapping effort, these Red Brook Harbor data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system.

Point Shapefile with a Point Every 100 meters Along the Neuse River 2004 Resistivity Survey Tracklines

The Neuse River Estuary in North Carolina is a broad, V-shaped water body located on the southwestern end of Pamlico Sound. This estuary suffers from severe eutrophication for which several water quality models have recently been developed to aid in the management of nutrient loading to the estuary. In an effort to help constrain model estimates of the fraction of nutrients delivered by direct ground-water discharge, continuous resistivity profile (CRP) measurements were made during the spring of 2004 and 2005. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to difference in salinity of submarine ground water. The 2004 and 2005 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software. CRP data enables the mapping of the extent and depth of the fresher ground water within the estuary.

Seafloor character offshore of Eureka, California

This seafloor character raster for the Offshore of Eureka, California, map area is part of USGS Data Series 781 (Golden and Cochrane, 2019). Seafloor character is a combination of seafloor induration (surface hardness) and rugosity, was derived from multibeam echosounder (MBES) and annotated underwater video data collected offshore of Eureka, California. The MBES and underwater video data were collected in support of the U.S. Geological Survey (USGS) California Seafloor Mapping Program, under a collaboration with the California State University Monterey Bay Seafloor Mapping Lab, the California Ocean Protection Council, and the National Oceanic and Atmospheric Administration (NOAA). Substrate observations from the underwater video were translated into Coastal and Marine Ecological Classification Standard (CMECS; Federal Geographic Data Committee, 2012) induration classes to use as training for a supervised numerical classification of the MBES data. The seafloor character raster is provided as a 2-meter resolution GeoTIFF.

Topographic Lidar Survey of the Alabama, Mississippi, and Southeast Louisiana Barrier Islands, from September 5 to October 11, 2012 -- Bare Earth Digital Elevation Models

A topographic lidar survey was conducted from September 5 to October 11, 2012, for the barrier islands of Alabama, Mississippi and southeast Louisiana, including the coast near Port Fourchon.  Most of the data were collected September 5-10, 2012, with a reflight conducted on October 11, 2012, to increase point density in some areas.
The data were collected at a nominal pulse space of 1-meter (m) and processed to identify bare earth elevations.
Bare earth Digital Elevation Models(DEMs) were generated based on these data.
Aero-Metric, Inc., was contracted by the U.S. Geological Survey (USGS) to collect and process the lidar data.
The bare earth DEMs are 32-bit floating point ERDAS Imagine (IMG) files with a horizontal spatial resolution of 1-m by 1-m. They are projected to UTM zone 15N or 16N NAD83 meters. Their vertical datum is NAVD88 (GEOID12) meters.
The DEMs are organized on a 2-kilometer (km) by 2-km tiling scheme that covers the entire survey area.
These lidar data are available to Federal, State and local governments, emergency-response officials, resource managers, and the general public.
