Thomas Jefferson New York Harbor Wrecks
NOAA Ship Thomas Jeffeson in New York Harbor with the Statue of Liberty in the background.  The NOAA Ship Thomas Jefferson conducted hydrographic survey operation in New York Harbor during the fall of 2006. Thomas Jefferson’s two survey launches (3101 and 3102) collected 200% Sides Scan Sonar and 100% Multibeam Sonar coverage in the harbor to update the nautical charts for the area. Most of the project area was previously surveyed prior to 1982 and parts of the project area had not been surveyed since 1927.

The upper New York Harbor is a dynamic environment with currents from three sources, the Hudson River, the East River, and the Atlantic Ocean. The area also experiences heavy vessel traffic from tourism, recreation and  the commercial/industrial sector. Containerized cargo volumes in the Port of New York and New Jersey rose 7.6% in 2005 to a record high with 5,322 ships called on the Port in 2005. All this combined made it a challenging work area for launches.



This is a poster produced by NOAA Ship Thomas Jefferson.  It shows numerous underwater images of wrecks throughout Rockaway Inlet in New York Harbor. Many small wrecks were found in and around Rockaway Inlet during a Multibeam Echo Sounding hydrographic survey of New York Harbor. The survey was conducted by NOAA launch 3101 and launch 3102 from the ship THOMAS JEFFERSON during the fall of 2006.
A few highlights from the survey work included locating many small wrecks in and around Rockaway Inlet (right) and finding a nearly intact wreck next to an uncharted pier in Dead Horse Bay (below).

Thomas Jefferson is one of four NOAA vessels primarily equipped for hydrographic survey operations in support of nautical charting . For more information on the Thomas Jefferson and other NOAA vessels visit NOAA’s Office of Marine and Aviation Operations.
