MODFLOW-NWT groundwater-flow models used to delineate areas contributing recharge to selected production wells in unconfined and confined glacial valley-fill aquifers in Chenango River Basin, New York

In the Chenango River Basin, New York, glacial valley-fill unconfined and confined aquifers 
are an important source of drinking-water supplies. The U.S. Geological Survey developed 
three-dimensional groundwater-flow models (MODFLOW-NWT code) of three study areas 
in the basin to improve understanding of groundwater flow and delineate areas contributing 
recharge to 16 production wells as part of an effort to protect the source of water to these 
wells. The modeled areas were the Cortland study area in Cortland County (CCSA), Greene 
study area (GSA), and the Cincinnatus study area (CSA). Production wells in CCSA tap 
unconfined aquifers, whereas the production wells in GSA and CSA are screened in confined 
aquifers. The CCSA, which has an extensive calibration dataset, was calibrated by nonlinear 
regression and included a prediction uncertainty analysis. The GSA and CSA were manually 
calibrated because of the sparse model design and calibration information. The groundwater-flow 
models along with particle tracking (MODPATH code) were used to simulate water levels, 
base flows, water budgets, and flow paths. The USGS data release contains all the input and 
output files and source codes for the simulations described in the associated report:

Surficial Sediment Facies features near the Myrtle Bend Confluence with the Kootenai River near Bonners Ferry, ID

The surficial bed-sediment facies, herein after referred to as the sediment facies, 
quantitatively describes the dominant sediment substrate on the surface of the 
river bed. Sediment facies categories were based on the grain size distribution 
of Wentworth (1922) which included the following ranges or combination of ranges: 
gravel (2-64mm), sand (0.063-2mm) and silt/clay (less than 0.063mm). An 
underwater video monitoring system UVMS was used to collect visual samples 
of the sediment facies determine the type and dominant size of the substrate, 
and record the geographical position of the substrate. UVMS data was collected 
intermittently at each site from 2006 – 2012.

Processed continuous resistivity profile data collected in Manhasset Bay on Long Island, New York on May 16, 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.

L908NC_video_observations

This part of DS 781 presents video observations from cruise L908NC for northern California. The vector data file is included in "l908nc_video_observations.zip," which is accessible from https://pubs.usgs.gov/ds/781/video_observations/data_catalog_video_observations.html.
Between 2006 and 2007, the seafloor in central California was mapped by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB) and by the U.S. Geological Survey (USGS), using both multibeam echosounders and bathymetric sidescan sonar units. These mapping missions combined to collect bathymetry and acoustic-backscatter data from about the 10-m isobath to out beyond the 3-nautical-mile limit of California's State Waters. To validate the interpretations of sonar data in order to turn it into geologically and biologically useful information, the USGS ground-truth surveyed the data by towing camera sleds over specific locations throughout the region. During the 2008 ground-truth cruise, the camera sled housed two video cameras (one forward looking and the other vertical looking), a high-definition video camera, and an 8-megapixel digital still camera. The video was fed in real time to the research vessel, where USGS and NOAA scientists recorded both the geologic and biologic character of the seafloor into programmable keypads once every minute. In addition to recording the seafloor characteristics, a digital still photograph was captured once every 30 seconds. This ArcGIS shape file includes the position of the camera, the time each observation was started, and the visual observations of geologic and biologic habitat.

Post-Hurricane Irene coastal oblique aerial photographs collected from Ocracoke Inlet, North Carolina, to Virginia Beach, Virginia, August 30-31, 2011

The U.S. Geological Survey (USGS) conducts baseline and storm-response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms. On August 30-31, 2011, the USGS conducted an oblique aerial photographic survey (during Field Activity Number [FAN] 11CCH04) from Ocracoke Inlet, North Carolina, to Virginia Beach, Virginia, aboard a Piper Navajo Chieftain aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (Figure 2, http://pubs.usgs.gov/ds/0979/html/ds979_fig2.html). This mission was flown to collect data for assessing incremental changes since the last survey, which was flown in May 2008 (https://cmgds.marine.usgs.gov/fan_info.php?fan=08ACH01), and can be used for assessing future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the position of the aircraft and do not indicate the location of the feature in the images. (See the Navigation Data page, for additional details: http://pubs.usgs.gov/ds/0979/html/ds979_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. ExifTool (http://www.sno.phy.queensu.ca/~phil/exiftool/) was used to add the following to the header of each photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet. All image times are recorded in Coordinated Universal Time (UTC). Table 1 (http://pubs.usgs.gov/ds/0979/html/ds979_table.html) provides detailed information about the assigned location, name, date, and time the photograph was taken along with a link to the photograph. In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail. The KML files were created using the photographic navigation files. Note: A KML number was assigned to each photograph to aid navigation of the Google Earth file. These numbers correspond to the site labels in Google Earth.

p192sc.m77t and p192sc.h77t: MGD77T data and header files for single-beam bathymetry data for field activity P-1-92-SC in Santa Monica Basin, Southern California from 01/30/1992 to 02/04/1992

Single-beam bathymetry data along with Loran-C and GPS navigation data was collected as part of the U.S. Geological Survey cruise P-1-92-SC. The cruise was conducted in Santa Monica Basin, Southern California from January 30 to February 4, 1992. The chief scientist was Bill Normark from the USGS Coastal and Marine Geology office in Menlo Park, CA and Dave Piper from the Geological Survey of Canada (GSC). The purpose of this cruise was to define the growth pattern of Navy Fan (offshore from San Diego in the California Continental Borderland) over the past few hundred thousand years. Specifically, the goals were to better understand the processes that lead to the formation of sandy submarine fans and the role of sea level changes in their formation. .The geophysical source was a Raytheon 12 kilohertz (kHz) PTR echosounder and ORE 3.5 kHz echosounder.
These data are reformatted from space-delimited ASCII text files located in the Coastal and Marine Geology Program (CMGP) InfoBank field activity catalog at http://walrus.wr.usgs.gov/infobank/p/p192sc/html/p-1-92-sc.meta.html into MGD77T format provided by the NOAA's National Geophysical Data Center(NGDC). The MGD77T format includes a header (documentation) file (.h77t) and a data file (.m77t). More information regarding this format can be found in the publication listed in the Cross_reference section of this metadata file.

Archive of Post-Hurricane Isabel Coastal Oblique Aerial Photographs Collected during USGS Field Activity 03CCH01 from Ocean City, Maryland, to Fort Caswell, North Carolina, and Inland from Waynesboro to Redwood, Virginia, September 21 - 23, 2003

On September 21 - 23, 2003, the U.S. Geological Survey (USGS) conducted an aerial survey along the Atlantic coast, from Ocean City, Maryland, to Fort Caswell, North Carolina, and inland from Waynesboro to Redwood, Virgina. These photos were used to document coastal changes such as beach erosion and overwash caused by Hurricane Isabel and to identify potential landslide areas inland. They may also be used as baseline data for future surveys. The USGS and the National Aeronautics and Space Administration (NASA) surveyed the impact zone of Hurricane Isabel to better understand the changes in vulnerability of the Nation’s coasts to extreme storms (Morgan, 2009). This report serves as an archive of the post-Hurricane Isabel oblique aerial survey photographs, survey maps, Google Earth files, location tables, navigation files, digital Field Activity Collection System (FACS) logs, and Federal Geographic Data Committee (FGDC) metadata. Attribute data including links to digital scans of the photographs are also provided. Latitude, longitude, and time were gathered simultaneously from three sources: video (with latitude/longitude and time stamps), photographs (with time stamps), and three Precision Lightweight GPS Receiver (PLGR) navigation files (without time) that documented the location of the aircraft. Location data were converted to decimal degrees and merged to create a location and time file that provided estimated location information for where each photograph was taken (see process step below). Slides were digitally scanned as TIFF image files at 3,000 dots per inch and were converted to JPEG images which are provided here. The metadata values for photo creation time, GPS latitude, GPS longitude, GPS position (latitude and longitude), keywords, credit, artist, caption, copyright, and contact were added to each photograph's EXIF header. Refer to the process steps below for more detail on each of these steps.

BS_Q23.TIF - Bering Sea U.S. EEZ GLORIA sidescan-sonar data mosaic (23 of 30) (LCC, 50 m, Clarke1866)

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 1986 through 1989, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the U.S. EEZ off Alaska. Four surveys during that time period (1986-1987) focused on the Bering Sea region. The results of these surveys were 30 digital mosaics of a 3 degree by 2 degree area with a 50-meter pixel resolution.

EAARL Coastal Topography–Eastern Louisiana Barrier Islands Barrier Islands, 09 March 2008: First Surface

A Digital Elevation Model (DEM) mosaic was data were produced from remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey (USGS). Elevation measurements were collected over some of the eastern Louisiana barrier islands in cooperation with the National Park Service (NPS), 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 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.
