NOAA Ship Ferdinand R. Hassler is a hydrographic survey vessel whose primary mission is to map coastal waters to update nautical charts. The ship also supports many other activities, including testing of autonomous underwater vehicles, buoy deployment and recovery, and general oceanographic research.
The shipâs side scan sonar collects imagery of the sea floor, which can identify obstructions or wrecks that could be navigational hazards. The sonar emits sounds waves in a swath, which generates a detailed image of objects on the sea floor.
The ship is one of NOAAâs most valuable assets following a severe weather event or ocean emergency. Even before she was officially commissioned in 2012, the ship was deployed in response to a U.S. Coast Guard request for assistance following Hurricane Irene. The ship conducted hydrographic surveys around the clock in Hampton Roads, Virginia, applying its state-of-the-art assets to looking at seafloor changes, searching for underwater hazards that would pose a danger to ships, and helping to restore port operations to its full capacity.
