Amphibious vehicle used to collect shoreface sub-bottom data

Detailed Description

USGS scientist Jennifer Miselis stands on board the US Army Corps of Engineers' (USACE) Lighter Amphibious Resupply Cargo (LARC). USGS collaborated with USACE to analyze coastal change due to Hurricane Sandy. Miselis is preparing to deploy a Chirp sub-bottom profiling system with a towfish attached in between the pontoons to collect sub-seafloor geological data. The purpose of this survey was to better understand how the geology of the shoreface varies along the length of Fire Island, New York and how that might impact post-storm recovery processes and barrier island response to sea-level rise.
