The United States Geological Survery sends out a Light Amphibious Resupply Cargo (LARC) as well as smaller remote control boats, call Q-Boats, into the newly formed inlet on Fire Island.  The LARC, being able to be driven on both land and in water, was originally manufactured for the NAVY in the 1960s, and has since been recommissioned for research purposes.  The LARC drives in lines, back and forth from the shore to a few hundred feet out into the water, on both sides of the breach.  As it does this the LARC gathers data about the shoreline and ocean floor, such as the depth and geographics of the area surrounding the inlet.

The smaller Q-boats are more easily able to infiltrate the actual inlet, gathering data about tidal velocity, depth, and the geographics of the inlet.  

The inlet, formed by Hurricane Sandy, is on the eastern end of Long Island in Shirley.  Many environmentalists would like to keep the inlet open, claiming that it has created more of diversity in sea life and has increased the quality of the water in the bay.  Opponents claim that the the breach leaves Fire Island vulnerable for the next storm, and are seeking to have it filled.  Studies since the storm have shown that the tides in the bay side have no seen any particularly drastic changes- but this measurement will not be able to determine the intensity of tidal surges during storms.
