NOAA Navigation Response Team 5 surveying Liberty Island in April 2013.
NOAA kicked off its spring season with post-Hurricane Sandy hydrographic work on April 11. A NOAA navigation response team—equipped with high-tech surveying equipment—began a survey in the waters surrounding Liberty Island and Ellis Island.
At the request of the National Park Service, Coast Survey's Navigation Response Team 5 (NRT5), one of the first in-water responders to help re-open the Port of New York and New Jersey immediately after Hurricane Sandy, is working to re-establish safe navigation and docking at the Statue of Liberty, in preparation for its planned re-opening on July 4.
Equipped with multibeam echo-sounding technology and side scan sonar, NRT5 will locate storm debris and identify areas that have depths suitable for the installation of temporary floating docks. If NRT5 finds a danger to navigation, they provide the information to Coast Survey cartographers. If warranted, Coast Survey will publish a Notice to Mariners (NM), and distribute the NM to the U.S. Coast Guard. The team will deliver survey results (including any pertinent images) to the National Park Service Submerged Resources Center.
