Abstract:
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, conducted a bathymetric survey of Fire Island, New York, from October 5 to 10, 2014. The U.S. Geological Survey is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the wilderness breach, which formed in October 2012 during Hurricane Sandy, as part of the Hurricane Sandy Supplemental Project GS2-2B. During this study, bathymetry data were collected, using single-beam echo sounders and global positioning systems mounted to personal watercraft, along the Fire Island shoreface and within the wilderness breach, Fire Island Inlet, Narrow Bay, and Great South Bay east of Nicoll Bay. Additional bathymetry and elevation data were collected using backpack and wheel-mounted global positioning systems along the subaerial beach (foreshore and backshore), and flood shoals and shallow channels within the wilderness breach and adjacent shoreface.
Purpose:
To determine the change Hurricane Sandy caused in the shoreface morphology and breach evolution at Fire Island, New York, USA, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a bathymetric survey of Fire Island from October 5 to 10, 2014. The objectives of the data collection effort were to map the morphology of the wilderness breach and adjacent shoreface, Fire Island Inlet, Narrow Bay, and Great South Bay east of Nicoll Bay the shoreface as part of the USGS Hurricane Sandy Supplemental Project GS2-2B. This dataset, 201410_Ground_Based_XYZ_Bellport_Bay.zip, consists of elevation data collected from Bellport Bay, using a backpack GPS system, where personal watercrafts (PWC) were unable to survey.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the data is determined during data collection. This dataset is derived from a single field survey using identical equipment, setup procedures, and staff; therefore, the dataset is internally consistent. Methods are employed to maintain data collection consistency. During setup, each piece of equipment is isolated to obtain internal and external offset measurements with respect to the survey mount. All the critical measurements are recorded manually and digitally entered into their respective programs. For backpack collected elevations, the antenna height relative to the ground was measured for the surveyor in a walking stride position and accounted for during post-processing. For the wheel-mount collected elevations, the antenna height relative to the ground was 2 m and accounted for during post-processing.
Logical_Consistency_Report:
The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center collected shallow water bathymetric data in the wilderness breach, Bellport Bay, Narrow Bay, Great South Bay east of Nicoll Bay, Fire Island Inlet, and the ocean shoreface within approximately 2.5 kilometers (km) of Wilderness Breach. Backpack-collected GPS was collected over subaerial and shallow flood shoals. Wheel-mounted GPS was collected on the subaerial beach. This zip archive contains the post-processed backpack and wheel-mounted (ground based) GPS data (x, y, z) from October 2014 that were acquired during a single field survey.
Completeness_Report:
This is a complete, post-processed x,y,z bathymetric data point file acquired with a backpack GPS system within Bellport Bay, New York.

Horizontal_Positional_Accuracy_Report:
The GPS antenna and receiver acquisition configuration used at the base station was duplicated on the survey mount (rover). The base receiver and the rover receiver recorded their positions concurrently at 10 Hz recording intervals throughout the survey. All processed measurements were referenced to the base station coordinates. All static base station GPS sessions were submitted for processing to the Online Positioning User Service (OPUS), which was created by the National Oceanic and Atmospheric Administration/National Geodetic Survey (NOAA/NGS). OPUS results provided an error measurement for each daily solution with a horizontal accuracy estimated as 0.007 m root mean squared (RMS). The combined horizontal error is assumed to be at most half of the vertical offset.

Vertical_Positional_Accuracy_Report:
The GPS antenna and receiver acquisition configuration used at the base station was duplicated on the survey mount (rover). The base receiver and the rover receiver recorded their positions concurrently at 10 Hz recording intervals throughout the survey. All processed measurements are referenced to the base station coordinates. OPUS results provided an error measurement for each daily solution. Applying these error measurements, the vertical accuracy of the base station was estimated to be 0.007 m root mean squared (RMS). The kinematic (rover) trajectories were processed using GrafNav v8.50 software by Novatel, Inc. Occurrences where a backpack and(or) wheel-mounted GPS trackline crossed a line it previously surveyed were evaluated to determine vertical error. The combined vertical error from base station coordinate solutions and rover trajectories was 0.125 m.

Process_Description:
GPS Acquisition: Horizontal and vertical positioning of each vessel and backpack was were collected determined using a base-rover configuration. Data were recorded at 10 Hertz (Hz) using Ashtech ProFlex™ 500 Global Navigation Satellite System (GNSS) receivers with Thales choke ring antennas. Three stationary base stations (REST, VC, and U374) were occupied during the surveys. The stationary base at published NGS benchmark U374 (Permanent Identification number (PID#) KU0206) was equipped with an Inmarsat Broadband Global Area Network (BGAN) satellite uplink system for remote monitoring of the base station. U374 consisted of an Ashtech Proflex 500 GNSS receiver and an Ashtech choke ring antenna with a vertical offset of 1.24 meters (m). GPS data acquired by the PWCs, backpack, wheel-mount, and the REST and VC base stations were downloaded at the end of each survey day. A small segment of the U374 data was downloaded via the BGAN network nightly to ensure the system was operating properly. Reference station coordinates were verified with Continuously Operating Reference Stations (CORS) stations using OPUS, (http://www.ngs.noaa.gov/OPUS/). OPUS computed reference positions had a vertical error of 0.007 m and horizontal errors of 0.8 cm and 0.6 cm for East-West and North-South, respectively.

Process_Description:
Backpack GPS Acquisition: Elevation data were collected from shallow flood shoals and channels, using a SECO GPS backpack containing an Ashtech Z-Xtreme receiver with Ashtech Marine antennas attached to a pole extending above the head of the surveyor. Positions were recorded at 10 Hz. The elevation of the antenna relative to the ground was measured for the surveyor in a walking stride position (2.112 m). The surveyors did not follow a pre-defined path but collected data over as much of the subaerial and shallow shoals as possible during low-tide.

Process_Description:
Ground-Based Uncertainty Calculation: Backpack GPS elevation errors were calculated by computing the vertical differences at crossings occurring at least 1 minute apart. Using Matlab, the calculated RMS error was 12.5 cm. Elevation differences between the ground-based data points and single-beam data points indicate the backpack elevations were 5 cm higher than elevations recorded using PWCs. Given the high degree of uncertainty arising from the backpack surveyor striding over a subaqueous shoal surface, the ground-based data were adjusted to the PWC elevation at the crossings. The adjusted positions, elevation, and date of sampling were saved as an ASCII file.

Extract Bellport Bay XYZ: The adjusted backpack data points were imported into ArcGIS using the “create feature class from XY table” tool in ArcCatalog. A polygon was then created surrounding the data points within Bellport Bay. The polygon vertices were converted to points using the “feature vertices to points” tool, “add XY coordinates” tool, and exported as an ASCII file using the “export feature attribute to ASCII” tool. This polygon ASCII file was subsequently imported into Matlab. Ground-based data points within or on this polygon were then extracted and saved as an ASCII file.
