Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>In order to extend the benthic habitat maps, groundtruth validation is necessary along much of the reef edge throughout the sanctuary. NCCOS continued operations from previous years deploying a drop camera for drifts across the reef edge in the Marquesas, Dry Tortugas Ecological Reserve, and Riley's Hump. This shapefile contains the site name, the date of collection, first coordinate of the drift, a coordinate if the habitat changes, the end coordinate, benthic habitat information, bottom habitat category, drift direction, depth, and links to the drift video clips. </SPAN></SPAN><SPAN><SPAN>The videos were collected with two video cameras mounted in a stainless steel frame. One was a lower resolution (720p) camera (Sartek Industries Inc.) that was teathered to the surface where the video was recorded to a DVR. The other was a higher resolution (1080p) GoPro. The lower resolution camera was down looking – perpendicular to the bottom. Video from the low resolution camera could be viewed at the surface and was used to locate the bottom and maintain a viewable, safe distance from it. The GoPro was the video source used in the FKNMS Digital Atlas.</SPAN></SPAN></P></DIV></DIV></DIV>
