2014 East Coast Maine USACE/NAE ATM Lidar-Derived Dune Crest, Toe and Shoreline, post-Hurricane Sandy

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2014 East Coast Maine United States Army Core of Engineers (USACE) National Academy of Engineering (NAE) topobathymetric (topobathy) lidar survey, post-Hurricane Sandy. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

Airborne geophysical survey: Nushagak Bay

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field intensity values and location. In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.

Geodatabase of the datasets that represent the five vertical subunits of the Coastal Lowlands aquifer system, Alabama, Florida, Louisiana, Mississippi, and Texas

This geodatabase contains spatial datasets that represent the Coastal Lowlands 
aquifer system in the States of Alabama, Florida, Louisiana, and Texas. Included are: 
(1) polygon extents; datasets that represent the aquifer system extent, the entire extent 
subdivided into subareas or subunits, and any polygon extents of special interest 
(outcrop areas, no data available, areas underlying other aquifers, anomalies, for example), 
(2) altitude, and/or if applicable, thickness contours used to generate the surface rasters, 
(3) raster datasets for the altitude of each aquifer subarea or subunit, 
(4) georeferenced images of the figures that were digitized to create the altitude or thickness 
contours. 
The images and digitized contours are supplied for reference.
			
The extent of the Coastal Lowlands aquifer system is from the combined digitized linework 
of the Coastal Lowlands aquifer system extent maps in U.S. Geological Survey Professional 
Paper 1416-C (USGS PP 1416 C), plates 9, 10, 11, 14, and 16, figures A. Included is the 
"no data available" extent of Subarea 2 (see description below).
			
The Coastal Lowlands aquifer system has 5 aquifer subunits, A = shallowest, B, C, D, E = deepest. 
There are two subareas. Subarea 1 is the area described in USGS PP 1416-C. Subarea 2 is the 
part of the aquifer in Alabama and Florida, east of the USGS PP 1416-C extent; there are no data 
for this subarea. 
			
The altitudes of the top surfaces of the subunits were digitized from georeferenced images of 
altitude contours; the altitudes of the bottom surfaces of the subunits were generated from 
the thickness contours of each subunit.
	Subunit A1 (Holocene - upper Pleistocene deposits, Permeable Zone A)
	Subunit A2 (lower Pleistocene - upper Pliocene deposits, Permeable Zone B)
	Subunit A3 (lower Pleistocene - upper Miocene deposits, Permeable Zone C)
	Subunit A4 (middle Miocene deposits, Permeable Zone D)
	Subunit A5 (lower Miocene - upper Oligocene deposits, Permeable Zone E)
				
Digitizing of the extent and thickness/altitude linework was done by the USGS 
Oklahoma Water-Science Center.
				
Subunit thickness datasets, and altitude datasets were interpolated into surface 
rasters within a GIS using tools that create hydrologically correct surfaces from 
contour data, derives the altitude from the thickness (depth from the overlying surface), 
and merges the subareas into a single surface. The primary tool was "Topo to Raster" 
used in ArcGIS, ArcMap, Esri 2014

Time Series of Autonomous Carbonate System Parameter Measurements in Eastern Gulf of Mexico near Tampa Bay, Florida, USA

This dataset contains carbonate system data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center to investigate the effects of carbon cycling, coastal and ocean acidification in the Gulf of Mexico near the Tampa Bay estuary located in west central Florida, USA. These data were collected using an autonomous instrument called the Ocean Carbon System version 3 (OCSv3) deployed on the University of South Florida (USF), Coastal Ocean Monitoring and Prediction System (COMPS) Buoy C12. The OCSv3 consists of four sensors integrated into a Sea-Bird Scientific STOR-X submersible data logger including a Sea-Bird SeapHOx sensor for measurement of pH that incorporates a Sea-Bird SBE 37-SMP-ODO MicroCAT C-T-ODO (P) Recorder for measurement of conductivity (for calculation of salinity), temperature, depth, and dissolved oxygen; a Pro-Oceanus CO2-Pro CV CO2 sensor; and a Wetlabs Eco-PAR sensor for measurement of photosynthetically active radiation. The dataset is a time series of carbonate system parameters including: water temperature (Celsius, °C), pressure (decibar, dbar), salinity, pHT (pH on the total scale), carbon dioxide (parts per million, ppm), pressure from the CO2-Pro Infrared Gas Analyzer (IRGA) (millibars, mbar), dissolved oxygen (milligrams per liter, mg/L) and photosynthetically active radiation (microEinsteins). Each parameter was measured every hour for 24-hour time periods throughout the duration of deployment.

Backscatter [8101]--Offshore of Monterey, California

This part of DS 781 presents data for the acoustic-backscatter map of the Offshore of Monterey map area, California. Backscatter data are provided as separate grids depending on resolution. This metadata file refers to the data included in "Backscatter_8101_OffshoreMonterey.zip," which is accessible from https://doi.org/10.5066/F70Z71C8. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Hartwell, S.R., Cochrane, G.R., Golden, N.E., Watt, J.T., Davenport, C.W., Kvitek, R.G., Erdey, M.D., Krigsman, L.M., Sliter, R.W., and Maier, K.L. (S.Y. Johnson and S.A. Cochran, eds.), 2016, California State Waters Map Series—Offshore of Monterey, California: U.S. Geological Survey Open-File Report 2016–1110, pamphlet 44 p., 10 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20161110. 
The acoustic-backscatter map of the Offshore of Monterey map area in central California was generated from backscatter data collected by California State University, Monterey Bay (CSUMB) and by Monterey Bay Aquarium Research Institute (MBARI). Mapping was completed between 1998 and 2012 using a combination of multibeam echosounders including 200-kHz/400-kHz Reson 7125, 100-kHz Reson 7111, 240 kHz Reson 8101, and 30-kHz Simrad EM-300 as well as 234-kHz and 468-kHz SWATHplus bathymetric sidescan-sonar system. Within the final imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic pulse and the seafloor, as well as characteristics within the shallow subsurface, providing a general indication of seafloor texture and composition. Backscatter intensity depends on the acoustic source level; the frequency used to image the seafloor; the grazing angle; the composition and character of the seafloor, including grain size, water content, bulk density, and seafloor roughness; and some biological cover. Harder and rougher bottom types such as rocky outcrops or coarse sediment typically return stronger intensities (high backscatter, lighter tones), whereas softer bottom types such as fine sediment return weaker intensities (low backscatter, darker tones).

Bathymetric Data collected with Backpack and Wheel-mounted GPS within and around the Wilderness Breach, Fire Island, New York, (2014) in XYZ ASCII Text File Format

Scientists from the U.S. Geological Survey St. Petersburg Coastal
and Marine Science Center in St. Petersburg, Florida, conducted a
bathymetric survey of Fire Island, New York, from October 5 to 10,
2014. The U.S. Geological Survey is involved in a post-Hurricane
Sandy effort to map and monitor the morphologic evolution of the
wilderness breach, which formed in October 2012 during Hurricane
Sandy, as part of the Hurricane Sandy Supplemental Project GS2-2B.
During this study, bathymetry data were collected, using single-beam
echo sounders and global positioning systems mounted to personal
watercraft, along the Fire Island shoreface and within the
wilderness breach, Fire Island Inlet, Narrow Bay, and Great South
Bay east of Nicoll Bay. Additional bathymetry and elevation data
were collected using backpack and wheel-mounted global positioning
systems along the subaerial beach (foreshore and backshore), and
flood shoals and shallow channels within the wilderness breach and
adjacent shoreface.

Underwater temperature on off-shore coral reefs of the Florida Keys, U.S.A. (Version 7)

The U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies (CREST) project (https://coastal.er.usgs.gov/crest/) provides science that helps resource managers tasked with the stewardship of coral reef resources. Coral reef organisms are very sensitive to high and low water-temperature extremes. It is critical to precisely know water temperatures experienced by corals and associated plants and animals that live in the dynamic nearshore environment to document thresholds in temperature tolerance. This dataset provides underwater temperature data recorded every fifteen minutes from 2009 to 2021 at six off-shore coral reefs in the Florida Keys, USA. From northeast to southwest, these sites are Fowey Rocks (Biscayne National Park), Molasses Reef (Florida Keys National Marine Sanctuary, FKNMS, site terminated in 2013), Crocker Reef (FKNMS, site added in 2013), Sombrero Reef (FKNMS), Pulaski Shoal Light (Dry Tortugas National Park), and Pulaski Shoal West (Dry Tortugas National Park, site added in 2016). Portions of the dataset included here were interpreted in conjunction with coral and/or algal calcification rates in publications including Kuffner and others (2020), and Lenz and others (2021). See the cross-reference section of the metadata for a complete list of publications.

EAARL Bare Earth Topography-Fire Island National Seashore

A bare earth elevation map (also known as a Digital Elevation Model or DEM) of Fire Island National Seashore was produced from remotely-sensed, geographically-referenced elevation measurements in cooperation with the U.S. Geological Survey (USGS), National Air and Space Administration (NASA), and the National Park Service (NPS). Elevation measurements were collected over the area using the 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 50 meters per second at an elevation of approximately 300 m. The EAARL, developed by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 15 centimeters. A sampling rate of 3 kHz or higher results in an extremely dense spatial elevation data set. Over 100 kilometers of coastline can be easily surveyed within a 3- to 4-hour mission time period. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.
