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 Marquesas and the western edges of Tortugas Banks and Rileys Hump in the FKNMS.
<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN><SPAN>This shapefile contains still images and associated coordinates collected from dives conducted during the Nancy Foster Cruise NF 20-08. This effort is part of a larger initiative to describe habitats and fish communities found in depths greater than 20 m for future management decisions.</SPAN></SPAN><SPAN STYLE="font-weight:bold;"><SPAN> </SPAN></SPAN><SPAN><SPAN>The SubAtlantic Mohawk 18 collected video images along transects of bottom features of interest identified from past multibeam seafloor surveys and identified habitat types along these features. 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. 14 Remotely Operated Vehicle (ROV) dives for ground truthing were completed over the course of the 6 day mission, from September 10th to the 12th, 2020. From September 12th to the 15th, the Nancy Foster began surveying and conducting more ROV dives on the FKNMS sheet south Marquesas until the end of the data acquisition.</SPAN></SPAN></P><DIV><DIV><P><SPAN /></P></DIV></DIV></DIV>
