The SEAHORSE AUV, developed by Penn State University, is the Naval Meteorology and Oceanography Command's (www.cnmoc.narg.mil) modular autonomous underwater vehicle that gathers side-scan images of the ocean bottom, ocean current data using acoustic Doppler current profilers, water-column temperature and salinity, and bathymetry. More than 9,000 alkaline D-cell batteries power the AUV to last over 90 hours and more than 300 miles. Based on commercial off-the-shelf technology to simplify maintenance at sea, the SEAHORSE works autonomously.
