Description:

Abstract:

This dataset, 20130626_bathy_xyz.zip, consists of single-beam point data collected in June 2013 during a bathymetry survey of the Wilderness Breach and adjacent coastline that has been output in American Standard Code for Information Interchange (ASCII) format. Scientists from the U.S. Army Corps of Engineers (USACE), in collaboration with the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), conducted a bathymetric survey from June 22-26, 2013. The survey focused on a breach (Wilderness Breach) created by Hurricane Sandy near Pelican Island, NY, which is located in Great South Bay. A total of 41 shore-perpendicular transects with a 50-meter spacing were collected using a Knudsen 320BP single-beam echosounder, centered on the breach.

Purpose:

In October 2012 Hurricane Sandy created a new breach in Fire Island, one of the barrier islands along the southern coast of Long Island, New York. The objective of this study was to create an updated bathymetric map in order to better understand the geomorphological progression of the breach.

Supplemental_Information:

Data were collected onboard the LARC-5 survey vehicle, which is 10.6 m (35 ft) long, 3 m (10.2 ft) wide and 3.3 m (11 ft) tall. It has a maximum land speed of 40 kph (25 mph) and approximately 11 kph in water, with a typical survey speed of 7 kph. Data were collected during USGS field activity number (FAN) 13CCH06, additional survey details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=13CCH06.

Native_Data_Set_Environment:

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

A GPS base station was established on 22 June 2013 by USGS staff and occupied for three consecutive days before submitting the coordinates to the Online Positioning User Service (OPUS) for precise quality control.

Logical_Consistency_Report:

This dataset was acquired on one research event over the course of 5 days in 2013 and is therefore internally consistent. Forty-one shore-perpendicular transects with a 50-m spacing were acquired using a single-beam echosounder.

Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The LARC's onboard RTK GPS system computes its location from available transmitting GPS satellites. After it determines its location, the correction from the base station is received and applied to that computed position for a more accurate positioning. An accuracy of +/- 2 m in all three dimensions can thus be achieved. Horizontal Coordinate System: North American Datum 1983 (NAD83), meters Projection: New York State Plane Long Island, meters (3104)

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The Knudsen 320BP echosounder is capable of measuring depths as shallow as 10 cm. The accuracy is determined as three percent of the selectable depth range. The elevations of above water points are based on the height above the ground of the GPS antenna on the LARC. The GPS control monument was located on Fire Island at the National Park Service Visitor Center benchmark, with a latitude of 40 43 58.16252 and a longitude of -72 52 01.04782.

Lineage:

Process_Step:

Process_Description:

Single-beam data were collected in the Atlantic Ocean (offshore of Fire Island, NY), through the breached area and in Great South Bay (near Pelican Island, NY) onboard the USACE's LARC-5 amphibious vehicle. The LARC operator used the RTK GPS to follow a pre-defined course of survey lines entered into HYPACK, prior to the start of the survey. The Trimble 4000 RTK GPS software combined with HYPACK 2013 Hydrographic survey software helped ensure the operator stayed on course throughout data acquisition.

Process_Date: 2013

Process_Step:

Process_Description:

HYPACK software was used to merge the GPS and echosounder data to create text files, in .RAW format, which were later analyzed by the custom-built USACE Field Research Facility FORTRAN software. Conductivity, temperature and depth (CTD) were measured at the beginning of the survey (at the -8m isobath) and at the end of the survey (at the -8m isobath) aboard the LARC to determine the speed of sound in the water column. The time-stamp on the echosounder was corrected for 'drift' using the GPS time clock. The custom FRF software was used to remove the motion of the LARC due to waves and changing tide level. It also adjusted the measurements to changes in the speed of sound over the survey area and correctly aligned the time of the echosounder and the GPS data. This was done by dynamically adjusting the time or latency of the GPS data relative to the echosounder data until a best fit was achieved.

Process_Date: 2013

Process_Step:

Process_Description:

Land points were separated from points in the water by first computing the average and standard deviation for all GPS elevations collected when the echosounder data indicated that the LARC was floating.

Process_Date: 2013

Process_Step:

Process_Description:

Post-processed topographic-bathymetric data from USACE were imported into ArcGIS 10.2.1, converted to the NAD 1983 UTM Zone 18N coordinate system. Errant data points were manually removed from the data. The edited X,Y,Z points were exported from ArcGIS into an ASCII text file.
