JI_Q10.TIF - Johnston Island U.S. EEZ GLORIA sidescan-sonar data mosaic (10 of 16) (LCC, 50 m, WGS84)

In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology, launched a program using the Geological LOng-Range Inclined Asdic (GLORIA) sidescan-sonar system to study the entire U.S. Exclusive Economic Zone (EEZ). From December 1990 through February 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted three surveys within the Johnston Atoll U.S. EEZ surrounding Johnston Island. The results of these surveys were 16 digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution.

CACO2002_EAARLA_FS_z19_n88g12B_metadata: EAARL Coastal Topography--Cape Cod National Seashore, Massachusetts, 2002: First Surface

ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements acquired cooperatively by the U.S. Geological Survey (USGS) and the National Park Service (NPS). Elevation measurements were collected over Cape Cod National Seashore using the first-generation National Aeronautics and Space Administration (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 60 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 originally by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 3 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 resultant 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 two subunits of the Central Valley aquifer system, California

This geodatabase includes spatial datasets that represent the Central Valley 
aquifer system in the State of California. Included are: (1) polygon extents; 
datasets that represent the aquifer system extent, the entire extent subdivided 
into subareas or subunits, (2) raster datasets for the altitude of each aquifer 
subarea or subunit, (3) altitude, and thickness contours used to generate the 
surface rasters, (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 Central Valley aquifer system is from the spatial dataset of the 
USGS Professional Paper 1766 (USGS PP 1766) alluvial aquifer extent - modified 
to make internal areas where the aquifer is not present equal to "Null" - and was 
referenced to a digital version of the aquifer extent presented in the Groundwater 
Atlas of the United States (the U.S. Geological Survey Hydrologic Atlas 730-B 
(USGS HA 730-B).
			
The Central Valley aquifer system has two aquifer subunits, in order from the most 
surficial to the deepest: A1: continental deposits, A2: marine deposits. The altitude 
and thickness contours for each subunit were digitized from georeferenced figures 
of altitude contours in U.S. Geological Survey Professional Paper 1401-D 
(USGS PP 1401-D), and U.S. Geological Survey Open File Report 95-96 
(USGS OFR 95-96). The resultant top and bottom altitude values were interpolated 
into surface rasters with a GIS using tools that create hydrologically correct surfaces 
from contour data, deriving the altitude from the thickness (depth from the land surface). 
The primary tool was a  version of "Topo to Raster" used in ArcGIS, ArcMap, Esri 2014.

2011 East Coast New York/New Jersey NOAA/NGS 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 2011 East Coast New York/New Jersey National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS) 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.

GAK_250M_LCC_WGS84.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar composite mosaic (LCC, 250 m, WGS84)

The Gulf of Alaska U.S. EEZ GLORIA digital sidescan-sonar mosaic covers about 806,000 square kilometers (sq km) of sea-floor. The mosaic shows the sea-floor morphology from Uminak Pass to Dixon Entrance, from the shelf break seaward to about 400 km. An additional 70-km-wide swath was imaged along the British Columbia margin to follow the trace of the Queen Charlotte Fault south of the Dixon Entrance. Major features visible on the mosaic include continental-margin deformation structures and submarine-channel systems. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the sea-floor. A total of 30 digital mosaics with a 50-meter pixel resolution were assembled to complete the Gulf of Alaska overview mosaic.

RES2DINV format continuous resistivity profile data collected by the U.S. Geological Survey in Great South Bay on Long Island, New York, on Sept. 24, 2008

An investigation of submarine aquifers adjacent to the Fire Island National Seashore and Long Island, New York, was conducted to assess the importance of submarine groundwater discharge (SGD) as a potential nonpoint source of nitrogen delivery to Great South Bay. More than 200 kilometers (km) of continuous resistivity profiling (CRP) data were collected to image the fresh-saline groundwater interface in sediments beneath the bay. In addition, groundwater sampling was performed at sites (1) along the northern shore of Great South Bay, particularly in Patchogue Bay, that were representative of the developed Long Island shoreline, and (2) at sites on and adjacent to Fire Island, a 50-km-long barrier island on the southern side of Great South Bay. Other field activities included sediment coring, stationary electrical resistivity profiling, and surveys of in-situ pore water conductivity. The onshore and offshore shallow hydrostratigraphy of the Great South Bay shorelines, particularly the presence and nature of submarine confining units, appears to exert primary control on the dimensions and chemistry of the submarine groundwater flow and discharge zones. Sediment coring has shown that the confining units commonly consist of drowned and buried peat layers likely deposited in salt marshes. Based on CRP data, low-salinity groundwater extends from 10 to 100 meters (m) offshore along much of the northern and southern shores of Great South Bay, especially off the mouths of tidal creeks, and beneath shallow flats to the north of Fire Island adjacent to modern salt marshes. Human modifications of much of the shoreline and nearshore areas along the northern shore of the bay, including filling of salt marshes, construction of bulkheads and piers, and dredging of navigation channels, has substantially altered the natural hydrogeology of the bay's shorelines by truncating confining units and increasing recharge near the shore in filled areas. Better understanding of the nature of SGD along developed and undeveloped shorelines of embayments such as this could lead to improved models and mitigation strategies for nutrient overenrichment of estuaries.

Tracklines of swath bathymetry collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center offshore of the Elizabeth Islands, MA, 2010 (2010-003-FA_Swath_tracklines.shp, ESRI polyline shapefile)

These data were collected under a cooperative agreement between the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (&lt;http://woodshole.er.usgs.gov/project-pages/coastal_mass/&gt;). The data collected in this study area located around the western extent of the Elizabeth Islands includes high resolution bathymetry, acoustic-backscatter intensity, seismic-reflection, and navigation data. These data were collected during a nearshore cruise in September 2010 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, an Edgetech 424 chirp subbottom profiling system, and 4 GPS antennae. More information about the cruise conducted as part of the project: Geologic Mapping of the Seafloor Offshore of Massachusetts can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage:

OahuN_baseline - Offshore baseline used to cast shore-perpendicular transects for measurement of historical shoreline positions along North Oahu, Hawaii (Camp Erdman to Kahuku)

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.

Klamath Basin Restoration Agreement Off-Project Water Program Sub-basin Analysis Pour Points v3

The Klamath Basin Restoration Agreement (KBRA) was developed by a diverse group of stakeholders, 
Federal and State resource management agencies, Tribal representatives, and interest groups to provide 
a comprehensive solution to ecological and water-supply issues in the Klamath Basin. The Off-Project 
Water Program (OPWP), one component of the KBRA, has as one of its purposes to permanently provide 
an additional 30,000 acre-feet of water per year on an average annual basis to Upper Klamath Lake through 
“voluntary retirement of water rights or water uses or other means as agreed to by the Klamath Tribes, to 
improve fisheries habitat and also provide for stability of irrigation water deliveries.” The geographic area 
where the water rights could be retired encompasses approximately 1,900 square miles. The OPWP 
area is defined as including the Sprague River drainage, the Sycan River drainage downstream of Sycan 
Marsh, the Wood River drainage, and the Williamson River drainage from Kirk Reef at the southern end 
of Klamath Marsh downstream to the confluence with the Sprague River. Extensive, broad, flat, poorly 
drained uplands, valleys, and wetlands characterize much of the study area. Irrigation is almost entirely 
used for pasture.
    To assist parties involved with decisionmaking and implementation of the OPWP, the U.S. Geological 
Survey (USGS), in cooperation with the Klamath Tribes and other stakeholders, created five hydrological 
information products. These products include GIS digital maps and datasets containing spatial information 
on evapotranspiration, subirrigation indicators, water rights, subbasin streamflow statistics, and return-flow 
indicators.
