Offshore baseline for Cape Cod coastal region generated to calculate shoreline change rates from Provincetown to the southern end of Monomoy Island, Massachusetts (CapeCod_baseline.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.  
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

EAARL Coastal Topography--Cape Hatteras National Seashore, North Carolina, Post-Nor'Ida, 2009: First Surface

A digital elevation model (DEM) of a portion of the National Park Service Southeast Coast Network's Cape Hatteras National Seashore in North Carolina, post-Nor'Ida (November 2009 nor'easter), was produced from remotely sensed, geographically referenced elevation measurements cooperatively by the U.S. Geological Survey (USGS) and the National Park Service (NPS). Elevation measurements were collected over the area using the 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 meters, resulting in a laser swath of approximately 240 meters with an average point spacing of 2-3 meters. 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 kilohertz or higher results in an extremely dense spatial elevation dataset. Over 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

Geodatabase of the datasets used to represent the High Plains aquifer, Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

This geodatabase includes spatial datasets that represent the High Plains aquifer 
in the States of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, 
Texas, and Wyoming. Included are: (1) polygon extents; datasets that represent the 
aquifer system extent, (2) raster datasets for the altitude of the top and bottom 
surfaces of the High Plains aquifer, (3) altitude contours of the top surface and of 
the bottom surface used to generate the surface rasters. The altitude contours are 
supplied for reference.
			
The extent of the High Plains aquifer is from the digital dataset U.S. Geological 
Survey Data Series 543 (USGS DS 543), and as a references, the digital version 
of the aquifer extent presented in the Groundwater Atlas of the United States 
(the U.S. Geological Survey Hydrologic Atlas 730-D, -E, and -C, 
(USGS HA 730-D, -E, -C). 
			
The altitude contours for the top surface of the High Plains aquifer are from digital 
datasets of U.S. Geological Survey Open-File Report 99-263 (USGS OFR 99-263), 
using the 1980 water-level data.
The altitude contours for the bottom surface of the High Plains aquifer are from the 
U.S. Geological Survey Open-File Report 98-393 (USGS OFR 98-393). The altitude 
of the bottom surface, or base, was originally from the High Plains Regional 
Aquifer-System Analysis study.
			
The resultant top and bottom altitude values were interpolated into surface rasters 
within a GIS using tools that create hydrologically correct surfaces from contour data, 
derive the altitude from the thickness (depth from the land surface), and merge the 
subareas into a single surface. The primary tool was an enhanced version of 
"Topo to Raster" used in ArcGIS, ArcMap, Esri 2014. The raster surfaces were 
corrected for the areas where the altitude of an underlying layer of the aquifer 
exceeded the altitude of an overlying layer.

CMECS geoform, substrate, and biotopes offshore of Tacoma, Washington

This part of USGS Data Series 935 (Cochrane, 2014) presents substrate, geomorphic, and biotope data in the Offshore of Tacoma, Washington, map area, a part of the Southern Salish Sea Habitat Map Series. Given the variable bathymetric resolution, the complex geologic history of the region, and the lack of acoustic backscatter data, automated and semi-automated classification schemes of classifying seafloor substrate and geoform were deemed to have very low accuracy. Instead, classification of these properties was performed manually following the Coastal and Marine Ecological Classification Standard (CMECS; Federal Geographic Data Committee, 2012) using observations from underwater video footage.
The best overall predictors of biotic assemblage were used to generate the CMECS biotopes. However, the nature of the biological data gathered makes it difficult to define clear biotopes. It was difficult to see or identify many organisms in the underwater video, and with an average of only 3-4 taxa identified per sampling unit, it is hard to characterize biotic assemblages. Some biological clusters of taxa were identified statistically for multiple map areas, and within each area, some of these groupings were found at consistent depths and/or with predictable substrates. The maps are not fine-grained enough to capture the physical variation seen within one-minute video units. Depth zones in the biotope map are based on Dethier (1992).

2-meter Swath interferometric backscatter data collected in 2014 by the U.S. Geological Survey along the Delmarva Peninsula, MD and VA (8-bit 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 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 Woods Hole Coastal and Marine Science Center 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

Mean-annual and mean-seasonal water-budget estimates from a Soil-Water-Balance model of the Appalachian Plateaus, 1980 through 2011

As part of the U.S. Geological Survey Groundwater Resources Program study of 
Appalachian Plateaus aquifers, mean-annual and mean-seasonal water-budget 
estimates for the period 1980 through 2011 were determined  for a 162,000 
square-mile area covering parts of New York, Pennsylvania, Maryland, Ohio, 
West Virginia, Kentucky, Virginia, Tennessee, North Carolina, Georgia, Alabama, 
and Mississippi. Mean-annual and mean-seasonal precipitation, recharge, and 
actual evapotranspiration (ET) estimates were derived from annual and monthly 
Soil-Water-Balance (SWB) model (McCoy and others, 2015; Westenbroek 
and others, 2010) output and compiled in a geodatabase. Precipitation estimates 
from the Appalachian Plateaus SWB model were derived from daily Daymet 
climate grids (Thornton and others, 2012). Estimates of recharge from the 
SWB model were calculated using a modified Thornthwaite-Mather soil-water 
accounting method (Thornthwaite and Mather, 1957; Westenbroek and others, 
2010). Estimates of ET from the SWB model were derived by adjusting a 
spatially-variable estimate of potential ET (Hargreaves and Samani, 1985) with 
estimates of precipitation and soil-moisture (Westenbrok and others, 2010). 
The geodatabase contains polygon and point feature classes representing the 
model grid cells and their centers, respectively, and two tables containing 
mean-annual and mean-seasonal estimates for each cell. Mean-annual 
estimates were computed for full calendar years (January through December) 
and are presented in inches per year (in/yr) for the 1980 through 2011 period. 
Mean-seasonal estimates for spring (March through May), summer (June 
through August) and fall (September through November) are presented in 
inches for the 1980 through 2011 period. Mean-seasonal estimates for 
winter (December through February), also presented in inches, were 
calculated for December 1980 through February 2011.

Raw and modified raw continuous resistivity profile data collected in Manhasset Bay on Long Island, New York on May 15, 2008

An investigation of coastal groundwater systems was performed along the north shore of Long Island, New York during May 2008 to constrain nutrient delivery to Northport Harbor and Manhasset Bay by delineating locations of likely groundwater discharge. The embayments are bounded by steep moraines and are underlain by thick fine-grained sediments deposited in proglacial lakes during the last ice age. Beach sand and gravel overlie the glacial deposits along the coast. The continuous resistivity profiling (CRP) surveys that were conducted indicate the existence of low-salinity groundwater in shore-parallel bands, typically 25 to 50 meters wide, along the shorelines of both bays. Piezometer sampling and seepage meter deployments in intertidal and subtidal areas of the two bays confirmed the presence and discharge of brackish and low-salinity groundwater. The large tidal ranges (up to 3 meters), and the steep onshore topography and hydraulic gradients are important variables controlling coastal groundwater discharge in these areas. For more information on the survey involved in this project, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2008-007-FA.
