Coastwide Reference Monitoring System (CRMS) 2021 Site 0531 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.

Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska

Rhenium-osmium (Re-Os) geochronology of molybdenite provides a tool to directly date mineralizing events in hydrothermal systems. In the Yukon-Tanana upland of eastern Alaska, numerous molybdenite-bearing porphyry occurrences are recognized. The deposits are related to middle and Late Cretaceous granitoids (Kreiner and others, 2019; 2020). Some of the porphyry districts have multiple superimposed igneous events with relative timing relationships observed through detailed mapping and core logging. These timing relationships indicate multiple pulses of copper and molybdenite mineralization. This study dated molybdenite-bearing veins from porphyry occurrences across eastern Alaska. This includes five samples from the Taurus district, which attempted to directly date mineralization in an effort to understand which of the seven magmatic pulses was the main cause of mineralization.

Effects of Late Holocene Climate and Coastal Change in Mobile Bay, Alabama: ADCIRC Model Input and Results (Water_Level_RS_PH)

Using version 52.30 of the ADvanced CIRCulation (ADCIRC) numerical model (Luettich and others, 1992), astronomic tides were simulated at Mobile Bay, Alabama (AL), under scenarios of Holocene geomorphic configurations representing the period of 3500 to 2300 years before present including a breach in the Morgan Peninsula and a land bridge at Pass aux Herons, as described in Smith and others (2020). The two-dimensional ADCIRC model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and transport scenarios. For this study, the ADCIRC unstructured finite element mesh domain spans to the 60th meridian west in the Atlantic Ocean and has higher spatial resolution elements (20 - 100 meters (m)) along the northern Gulf of Mexico coast from Louisiana through the Florida Panhandle. The ADCIRC model setup requires the input of topographic and bathymetric elevations at each mesh node. Model inputs in the form of topography and bathymetry and model outputs in the form of water levels and velocities at each mesh node are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Smith and others (2020).

2010 Louisiana and Mississippi USACE Lidar-Derived Dune Crest, Toe and Shoreline

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 2010 Louisiana and Mississippi U.S. Army Corps of Engineers (USACE) lidar survey. 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.

Visible, Near Infrared, Shortwave Infrared and Thermal Infrared Laboratory Spectra of Samples of Compositionally Variable Dune Fields in the Western United States and Alaska - Sample DS8

This data represents laboratory reflectance and emissivity spectral measurements of dune sand samples collected from a variety of dune types and mineralogical compositions from eight dune field locations in Alaska, Arizona, California, Colorado, Idaho, Nevada and New Mexico (labeled and designated as samples DS-1 through DS-8). Each sample were sieved into various size classes and measured both prior to and after sieving. Visible through Near Infrared through Shortwave Infrared (~0.4 - 2.5 microns) reflectance were measured using an artificial light source attached to an Analytical Spectral Devices (ASD) spectrometer. Hemispherical reflectance measurements spanning Mid-IR wavelengths, including the Thermal Infrared (~2.0 - 15.0 microns), were measured using a Nicolet FTIR spectrometer with a gold integrating sphere attachment. These latter measurements were converted from wavenumber to wavelength, and inverted to measure emissivity. TIR spectral measurements were conducted for most of our eight dune samples prior to sieving and does not include measurements of various size fractions, except for one sample (DS-8). VSWIR reflectance measurements are included for each of the full composite samples prior to sieving, as well as selected size fractions after sieving such as the smallest (e.g. pan fraction) and largest measurable size fractions. This metadata entry describes the CSV spectral files associated with sample DS-8, in particular.

Physiographic Zones of the Sea Floor for Vineyard and western Nantucket Sounds, Massachusetts (polygon shapefile, Geographic, WGS84)

Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Vineyard and western Nantucket Sounds, Massachusetts. These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs, and surficial sediment samples. The interpretation of the seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of Massachusetts.

Sediment Volume and Bedrock of the Similkameen River Above Enloe Dam Near Oroville, Washington

This data release contains 3-meter gridded rasters of depth to bedrock below bathymetric surface, the thickness of unconsolidated sediment, and the volume of unconsolidated sediment within a 2.6-km reach of the Similkameen River, Okanogan County, Washington, impounded by Enloe Dam. These rasters were calculated from continuous resistivity profiles (CRP) surveyed using a SuperSting R8 8-channel resistivity meter with a CRP streamer containing a 100-m long array of 11 electrodes was towed behind a boat spaced at 10 m. After collection, the raw CRP files were georeferenced to coordinates concurrently by a global positioning system. Output files were merged and linearized. This was converted to a data file compatible with the software RES2DINV used to perform an inversion of apparent resistivity data to calculate a model of the true resistivity for each profile. Georeferencing and depth information were incorporated. Using Workbench GIS noisy data and data where the array turns were removed. Data was smoothed and an unconstrained 20-layer inversion applied allowing the depth of investigation to be calculated. Sediment-rock interface was interpreted along the 200-ohm-m contour. Points where resistivity indicated bedrock were output to ASCII file with their associated geographic coordinates.

Airborne lidar survey of St Vincent, Eastern Caribbean, following the 2020-21 eruption of La Soufrière Volcano

La Soufrière Volcano is a 1,220 m high stratovolcano that occupies the northern half of the island of St. Vincent, Lesser Antilles, Eastern Caribbean. It has a long history of explosive and sometimes devastating eruptions. Beginning in December 2020 and ending in April 2021, La Soufrière Volcano produced a Volcano Explosivity Index (VEI) 4 eruption that greatly impacted the landscape, communities, and infrastructure on the island of St. Vincent. The eruption produced intense ash plumes, heavy ashfall, and pyroclastic flows down several river valleys. During and following the eruption, destructive lahars (volcanic mudflows) impacted rivers valleys and coastal communities for months. The USGS-USAID Volcano Disaster Assistance Program (VDAP) provided remote assistance to our partners at the University of the West Indies Seismic Research Center (UWI-SRC) throughout the eruption, predominantly through satellite remote sensing observations. Following the eruption, VDAP contracted the acquisition of airborne lidar of the entire island to support our partners throughout the Eastern Caribbean to study the eruption’s impacts, assist in recovery and planning efforts, hazards modeling, and various other scientific investigations. This data release contains the results of this survey that include 0.6 m and 1 m resolution bare-earth digital elevation models (DEMs) and associated shaded-relief rasters of the island of St. Vincent. The DEMs cover approximately 400 square kilometers and were created from high-precision airborne lidar surveys performed between December 4, 2021-February 17, 2022. Some gaps exist in these data due to persistent, dense cloud cover in this tropical region. A shapefile of building footprints throughout the island is also included in this data release. Classified point cloud tiles and ortho imagery are available upon request.
