Summary of Activity and Data Gathered:
Notes: 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 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 objectives of this study were to create an updated bathymetric map in order to better understand the geomorphological progression of the breach.
Supplemental_Information: The LARC-5 survey vehicle 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.
