NOAA starts 2013 post-Sandy surveys at Statue of Liberty

NOAA kicked off its spring season for post-Sandy hydrographic work on April 11, as a navigation response team — equipped with high-tech surveying equipment — began a search for underwater storm debris and mapped the depths surrounding Liberty Island and Ellis Island. Navigation Response Team 5 wrapped up their project today, after surveying over 110 linear nautical miles. They surveyed for 119 hours, collecting over 578 million depth measurements.
In addition to surveying around Liberty Island and Ellis Island, Coast Survey’s NRT5 surveyed adjacent areas to acquire data for updates to NOAA’s nautical charts. This is the “rainbow” coverage map that shows the surveyed area. (The colors indicate depth.)
