NOAA Ship Thomas Jefferson prepared for 2013 survey season

By Ensign Brittany Anderson, Junior Officer, NOAA Ship Thomas Jefferson
After a quiet winter at home port, the NOAA Ship Thomas Jefferson completed her sea trials this week in preparation for the 2013 field season.
Each year, prior to departing for working grounds, the Thomas Jefferson transits to the Chesapeake Bay to perform tests on the ship’s and launches’ systems and hydrographic survey equipment. Crews conduct numerous tests to check the accuracy and precision of multibeam echosounders, side scan sonar, and the sophisticated suite of programs that process all the data.
