Vibracore photographs, computed tomography scans, and core-log descriptions from Pololu Valley, Island of Hawaii

This portion of the data release contains information on vibracores that were collected by the U.S. Geological Survey in Pololu Valley, Island of Hawai'i in 2014. Five sites were cored in order to describe wetland stratigraphy and to identify potential tsunami deposits. These vibracores contain mud, peat, fluvial sands, and marine volcanic sands, reflecting deposition in a variety of coastal environments. Two (2) pdf files (VC1.pdf, VC2.pdf) describe vibracores that were split, imaged by a line-scanner camera, scanned to generate computed tomagraphic (CT) images, and visually described. A detailed description of the upper 150 cm of VC1 using the Troels-Smith sediment classification scheme (Troels-Smith, 1955; Nelson, 2015) is included in VC1.pdf. Another pdf file (Pololu_cores_legend.pdf) contains a core-log legend. Cores VC3, VC4, and VC5 were collected using shorter sections (less than 200 cm) of extra pipe in order to capture the sand layer from the 1946 Aleutian tsunami that inundated the valley (Chague-Goff et al., 2012) and have not been photographed or CT-scanned. A comma-delimited text file (Pololu_sand_thickness.csv) includes tabulated information on the depth and thickness of sand beds P1, P2, and P3. In addition, a shapefile (pololu_vibracores_2014_locations.shp) provides sample locations of vibracores.

Velocity and water-surface elevation measurements from the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee

This dataset includes 4 sets of velocity measurements and water-surface elevation measurements collected at the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee between April 14, 2021 and September 8, 2021. 
Velocity data were collected by USGS staff from the Columbia Environmental Research Center at different locations in the study reach using an acoustic Doppler current profiler (ADCP) and Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) positioning. Data were used to evaluate the calibration performance of a one-dimensional hydraulic model of the WB reach. Velocity data are provided as mean velocity at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS.
Water-surface elevation data were collected by USGS staff from the Columbia Environmental Research Center using RTK GPS for the length of the study reach. Data were used to calibrate a one-dimensional hydraulic model of the WB reach. Water surface elevations are provided at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS.

Shot point navigation at 100 shot intervals for EdgeTech SB-512i chirp seismic-reflection data collected in May 2012 by the U.S. Geological Survey within the Baltimore Canyon, mid-Atlantic margin (Esri point shapefile, Geographic, WGS 84, BC_all100shot.shp)

A large number of high-resolution geophysical surveys between Cape Hatteras and Georges Bank have been conducted by federal, state, and academic institutions since the turn of the century. A major goal of these surveys is providing a continuous view of bathymetry and shallow stratigraphy at the shelf edge in order to assess levels of geological activity during the current sea level highstand.  In 2012, chirp seismic-reflection data was collected by the U.S. Geologial Survey aboard the motor vessel Tiki XIV near three United States mid-Atlantic margin submarine canyons. These data can be used to further our understanding of passive continental margin processes during the Holocene, as well as providing valuable information regarding potential submarine geohazards. For more information on the U.S. Geological Survey involvement in this effort, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2012-005-FA.

EAARL Topography-Thomas Stone National Historic Site

A first surface elevation map (also known as a Digital Elevation Model or DEM) of Thomas Stone National Historic Site 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.

Coastwide Reference Monitoring System (CRMS) 2021 Site 0338 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 398 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2021 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Five previous assessments have been conducted (2005, 2008, 2012, 2015/2016, and 2018). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Town Neck Beach, Massachusetts, 10 cm 2016-2017 Digital Elevation Models

Low-altitude (80-100 meters above ground level) Unmanned Aircraft Systems (UAS) imagery of Town Neck Beach in Sandwich, Massachusetts, were used in a structure-from-motion (SfM) photogrammetry workflow to create high-resolution topographic datasets. Imagery was collected at close to low tide on twelve days to observe changes in beach and dune morphology. Ground control points (GCPs), which are temporary targets on the ground located by using a real-time kinematic global navigation satellite system (RTK-GNSS) base station and rover, were used to constrain the SfM process. Photoscan (v. 1.2-1.4) was used to create a digital elevation model and orthomosaic for each data collection day. Collection of these data was supported by the U.S. Geological Survey Coastal/Marine Hazards and Resources Program and were conducted under USGS field activity numbers 2016-013-FA, 2016-043-FA, 2016-053-FA, 2016-054-FA, 2016-055-FA, 2017-005-FA, 2017-008-FA, 2017-010-FA, 2017-014-FA, 2017-027-FA, 2017-029-FA, and 2017-050-FA.

Sprague River Oregon Centerline Sycan 2005

The Sprague River drains 4090 square kilometers in south-central Oregon before flowing into the Williamson 
River and upper Klamath Lake. In cooperation with the U.S. Fish and Wildlife Service, the USGS and University 
of Oregon conducted a study to evaluate channel and floodplain processes for the 131 km of the Sprague River 
and its major tributaries, including the lower 20 km of the South Fork Sprague River, the lower 16 km of the North 
Fork Sprague River, and the lower 62 km of the Sycan River. The study involved multiple analyses, including 
assessments of historical channel change, riparian and floodplain vegetation, and surficial geology. To support 
these analyses, digital floodplain and channel maps were prepared from historic notes, maps, and aerial photos 
to depict channel and floodplain conditions at different times between 1866 and 2005. The geospatial database 
of current and historic channel and floodplain conditions will also enable evaluation of long-term trends pertaining 
to aquatic and riparian habitat conditions.

Salt Marsh Turbidity at Altamaha River, GA 2015-2017

We measured turbidity along a transect from channel to marsh interior for 1 year, beginning in June 2016 at a salt mash in the Altamaha River estuary. We measured turbidity (NTU) with three optical back scatter sensors to in a shore normal transect, with one in the channel (YSI 6600), and two on the marsh surface. The “marsh edge sensor” was 2.4m from the channel edge (Seapoint, RBR Solo) and the “marsh interior sensor” was 18m from the edge (Seapoint, RBR Duo; Figure 1c). The sensors measured every 15 minutes and were equipped with automatic wipers to reduce biofouling. Following retrieval, the turbidity time series data was filtered to remove any erroneous points and times when the sensors were fouled or exposed (Ganju et al. 2005).

National Park Service Thematic Burn Severity Mosaic for CONUS in 1985

The National Park Service (NPS) requests burn severity assessments through an agreement with the U.S. Geological Survey (USGS) to be completed by analysts with the Monitoring Trends in Burn Severity (MTBS) Program. The MTBS Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer is a thematic raster image of burn severity classes for all NPS-requested burn severity fires, occurring in CONUS during calendar year 1985. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available, or fires which were not discernable from available imagery.

Coefficient-based consistent mapping of imperviousness in the conterminous U.S. at 60-m resolution for 1974, 1982, 1992, 2002, and 2012

Anthropogenic impervious surfaces affect hydrology, water quality, and ecological health and are widely studied.  Previous studies have been limited, however, by a lack of consistent representation of imperviousness nationally as a time series prior to 2001.  This product presents estimated imperviousness at 60-meter spatial resolution, for the time periods 1974, 1982, 1992, 2002, and 2012.  The mapping was derived by comparing imperviousness from the National Land Cover Database (NLCD) 2011 to national land use from the 2012 U.S. Geological Survey NAWQA Wall-to-wall Anthropogenic Land Use Trends (NWALT) product. The NWALT land use product includes a series of 60-m national rasters, containing 18 land use classes, for five time periods from 1974-2012. Coefficients of imperviousness were derived for each land use class for 2012, and then re-mapped back to the NWALT previous eras of 2002, 1992, 1982, and 1974. The impervious mapping is facilitated by the 7-class urban detail of the NWALT land use product.  Coefficients were derived for each of 909 Census Core-Based Statistical Areas (CBSAs) in the conterminous U.S., and were thus tailored to the characteristics of specific metropolitan and rural areas.  When measured over HUC-12 watershed areas, the coefficients provided very similar 2002 imperviousness estimates to those from the 2001 NLCD:  r2 (RMSE) of 0.93 (0.6), and 96% of HUC-12s mapped to within 1% of their actual imperviousness value.  The resultant rasters provide a tool from which consistent measurements of imperviousness can be made for zonal or watershed areas in the conterminous U.S. for the last 4 decades.

Exposed Precambrian Bedrock in Part of Dickinson County, Michigan, and Marinette and Florence Counties, Wisconsin

The U.S. Geological Survey conducted a program of bedrock geologic mapping in much of the central and western upper peninsula of Michigan and parts of Wisconsin from the 1940’s until the late 1990’s. Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from glaciation of the region during the Pleistocene ice ages.  The USGS mapping, done largely at a scale of 1:24,000, routinely recorded the location and extent of exposed bedrock to provide both an indication of where direct observations were made, and as a guide for future investigations to expedite location of observable rock exposures.  The locations of outcrops were generally shown as colored or patterned overlays on printed geologic maps.  Although those maps have been scanned and are available as PDF files, no further digital portrayal of the outcrops has been done.  We have conducted a prototype study of digitizing and improving locational accuracy of the outcrop locations in parts of Dickinson County, Michigan, to form a data layer that can be used with other data layers in GIS applications.

Florida Keys Corals: A Photographic Record of Changes from 1959 to 2015

This data release contains time-series photographs taken of corals and coral habitats in the Florida Keys between 1959 and 2015 at Carysfort Reef and Grecian Rocks (a total of six sites). The original intent was to show coral reef recovery after Hurricane Donna devastated the area in 1960. Corals, especially elkhorn and staghorn coral, grew prolifically after the storm until the late 1970s, then began to decline, with the maximum period of decline centered around 1983 and 1984. These time-series photographs, showing the same individual coral colonies year after year, document the decline in coral health observed at these locations, mirroring patterns seen region-wide across the western Atlantic. A selection of the photographs was previously published (in low resolution) in Lidz and others (2006), wherein findings and conclusions related to these data were discussed.
