title: Archive of Ground Penetrating Radar and Differential Global Positioning System Data Collected in April 2016 from Fire Island, New York

description: Researchers from the U.S. Geological Survey (USGS) conducted a long-term, coastal morphologic-change study at Fire Island, New York, prior to and after Hurricane Sandy impacted the area in October 2012. The Fire Island Coastal Change project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving storm-related impacts, post-storm beach response, and recovery. In April 2016, scientists from the USGS St. Petersburg Coastal and Marine Science Center conducted geophysical and sediment sampling surveys on Fire Island to characterize and quantify spatial variability in the subaerial geology with the goal of subsequently integrating onshore geology with other surf zone and nearshore datasets also collected under the Disaster Relief Appropriations Act of 2013, using the U.S. Department of the Interior Hurricane Sandy supplemental funding. This data release serves as an archive of ground penetrating radar (GPR) and post-processed differential global positioning system (DGPS) data collected from beach and back-barrier environments on Fire Island, April 6-13, 2016 (USGS Field Activity Number 2016-322-FA). These data can be used to map shallow subsurface sediments such as erosional surfaces or washover deposits and can also be used to image deeper stratigraphic features that may aid in linking terrestrial geology to nearshore and offshore geologic features. Data acquisition and processing methods are described in USGS Data Series 1078.

title: USGS Field Activities 13BHM01 and 13BHM02 on the West Florida Shelf, Gulf of Mexico, July and August 2013

description: The United States Geological Survey (USGS) is studying the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in cruises on the West Florida Shelf and northern Gulf of Mexico regions aboard the research vessel (R/V) Weatherbird II or Bellows, ships of opportunity led by Dr. Kendra Daly, of the University of South Florida (USF) in July and August, 2013. Cruises left from and returned to Saint Petersburg, Florida, but followed different routes. The USGS collected geochemical data pertaining to pH, dissolved inorganic carbon (DIC), total carbon dioxide (TCO2), and total alkalinity (TA) in discrete samples at various depths from predetermined stations. Discrete surface samples were also taken, while in transit, during both cruises.

title: Radon-222 and Physical Water Column Parameter Data Concerning Submarine Groundwater Discharge Along the Western Margin of Indian River Lagoon, East-Central Florida-September 2016 to July 2017

description: 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 the 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. Note: This data release was versioned on March 12, 2018. Please see the Suggested Citation section for details.

title: National Assessment of Hurricane-Induced Coastal Erosion Hazards: Gulf of Mexico Update

description: These data sets contain information on the probabilities of hurricane-induced erosion (collision, inundation and overwash) for each 1-km section of the Gulf of Mexico coast for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the direct landfall of category 1-5 hurricanes. Hurricane-induced water levels, due to both surge and waves, are compared to beach and dune elevations to determine the probabilities of three types of coastal change: collision (dune erosion), overwash, and inundation. Data on dune morphology (dune crest and toe elevation) and hydrodynamics (storm surge, wave setup and runup) are also included in this data set. As new beach morphology observations and storm predictions become available, this analysis will be updated to describe how coastal vulnerability to storms will vary in the future. The data presented here include the dune morphology observations, as derived from lidar surveys. For further information regarding data collection and/or processing methods refer to USGS Open-File Report 2012?1084 (http://dx.doi.org/10.3133/ofr20121084).

title: ATRIS Seafloor Images-Crocker Reef, Florida, 2014

description: Underwater digital images, single-beam bathymetry, and global positioning system (GPS) data were collected June 24-25, 2014 within a 1-km x 1-km area around Crocker Reef in the Florida Keys, USA. A total of 91,206 images of the seafloor and water column were collected along pre-defined transect lines and organized into 3 sets: track1, track2, and track3. This data release contains a subset of those images (25,485 images), all of which were used for benthic habitat classification, and contain GPS data. The data were collected using the U.S. Geological Survey (USGS) shallow Along-Track Reef-Imaging System (sATRIS), a boat-based, pole-mounted sensor package for mapping shallow-water benthic environments. Two other implementations exist: A towed system called Deep ATRIS and a profiling system called Drift ATRIS. All three ATRIS implementations incorporate a digital still camera and an acoustic depth sounder.

title: Vector Shorelines and Associated Shoreline Change Rates Derived from Lidar and Aerial Imagery for Dauphin Island, Alabama: 1940-2015

description: In support of studies and assessments of barrier island evolution in the Gulf of Mexico, rates of shoreline change for Dauphin Island, Alabama, were calculated using two different shoreline proxy datasets with a total temporal span of 75 years. Mean High Water line (MHW) shorelines were generated from 14 lidar datasets from 1998 to 2014, and Wet Dry Line (WDL) shorelines were digitized from ten sets of georeferenced aerial images from 1940 to 2015. Rates of change for the open-ocean (south-facing) and back-barrier (north-facing) coast were calculated for three groups of shorelines: MHW (lidar), WDL (aerial) and MHW and WDL shorelines combined. Calculations were performed using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey (Thieler and others, 2009). For more information about the Digital Shoreline Analysis System (DSAS) see https://www.usgs.gov/centers/whcmsc/science/digital-shoreline-analysis-system-dsas.

title: Continuous Resistivity Profiling, Electrical Resistivity Tomography and Hydrologic Data Collected in 2017 from Indian River Lagoon, Florida

description: Researchers from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) in collaboration with USGS Caribbean-Florida Water Science Center (CFWSC) and St. Johns River Water Management District (SJRWMD) investigated spatial variability of bulk resistivity in the Surficial Aquifer located along the Indian River Lagoon (IRL), Florida, USA. Continuous resistivity profiling (CRP) measurements, electrical resistivity tomography (ERT), and hydrologic parameters (for example, depth and temperature) were mapped to investigate submarine groundwater discharge at two locations within IRL. The lagoon extends 200 kilometers (km) along the Atlantic coast of central Florida, varies between 0.5 and 9 km in width, and is characterized by shallow, brackish waters. Both study areas are located along the western shore of the lagoon within approximately 1000 m offshore from the mainland shoreline. Eau Gallie North (EGN) is positioned near the central section of IRL and Riverwalk Park (RWP) is approximately 20 km north of the EGN site. At each CRP study site, an 11-electrode marine resistivity array was towed over seven north-south shore parallel transects (EA-EG at EGN and RA-RG at RWP) measuring roughly 1.5 km in length. Repeat streaming resistivity surveys were collected bimonthly along these same tracklines, between March and October 2017, to determine seasonal and temporal variability. As part of 2017-328-FA and 2017-342-FA, additional stationary electrical resistivity tomography surveys were conducted proximal to the shoreline to further characterize the coastal aquifer beneath IRL. Three shore-perpendicular and three shore-parallel ERT surveys were conducted at both the EGN and RWP sites in May 2017 with the position of electrodes determined by a Real-Time Kinematic Global Positioning System (RTK-GPS). The surveys were repeated at EGN in September 2017 and at RWP in November 2017, using RTK-GPS to place electrodes at the exact location of the May-2017 survey. This data release serves as an archive of resistivity, global positioning system (GPS) and water column data collected in 2017 during USGS Field Activity Numbers 2017-313-FA, 2017-328-FA, 2017-334-FA, and 2017-342-FA. Data products including apparent resistivity, water depth and temperature, geographic coordinates, field notes, and inversion model images (which accounted for salinity and geologic parameters) are provided. Previously collected CRP resistivity data from December 2016 and January 2017 are available at, https://doi.org/10.5066/F7PZ5725.
