The FKNMS and NCCOS contracted the University of North Carolina in Wilmington, NC Undersea Vehicles Program to investigate the habitats found in depths deeper than 20 m in certain parts of the sanctuary. The ROV was piloted on dives on reefs and banks in the Tortugas Ecological Reserve North in the FKNMS.

The ROV collects georeferenced video and digital still photography. Navigation is provided by differentially corrected positioning system on the NOAA Ship Nancy Foster and offsets of ROV position provided by an ultra short baseline acoustic tracking system. Still images have time stamps that are synchronized with the navigation data and hyperlinked for viewing in the data atlas. 50 Remotely Operated Vehicle (ROV) dives for ground truthing were completed over the course of the 25 day mission, from March 18</SPAN></SPAN><SPAN><SPAN>th</SPAN></SPAN><SPAN><SPAN> to April 10</SPAN></SPAN><SPAN><SPAN>th</SPAN></SPAN><SPAN><SPAN>, 2021.</SPAN></SPAN></P></DIV>
