Summary

The natural resiliency of the New Jersey barrier island system, and the efficacy of management efforts to reduce vulnerability, depends on the ability of the system to recover and maintain equilibrium in response to storms and persistent coastal change. This resiliency is largely dependent on the availability of sand in the beach system. In an effort to better understand the system's sand budget and processes in which this system evolves, high-resolution geophysical mapping of the sea floor in Little Egg Inlet and along the southern end of Long Beach Island near Beach Haven, New Jersey was conducted from May 31 to June 10, 2018, followed by a sea floor sampling survey conducted from October 22 to 23, 2018, as part of a collaborative [...]

Purpose

This dataset contains trackline navigation for approximately 741 kilometers of multibeam echosounder bathymetry and backscatter data collected by the U.S. Geological Survey during cruise 2018-001-FA collected off southern Long Beach Island, New Jersey. This information can help spatially correlate the bathymetry and backscatter data with other geophysical data.
