<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>In order to extend benthic habitat map</SPAN></SPAN><SPAN><SPAN>s</SPAN></SPAN><SPAN><SPAN>, groundtruth validation is necessary along much of the reef edge. NCCOS continued operations from previous years deploying a drop camera for drifts across the reef edge in the</SPAN></SPAN><SPAN><SPAN> Lower Keys, and</SPAN></SPAN><SPAN><SPAN> Marquesas. 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. Underwater video was collected using system referred to as the “drop camera”. The unit consisted of a video camera that transferred its signal to the surface via cable where it was recorded to a DVR. The camera was mounted in a stainless steel frame that was tethered to a standard commercial fishing spooler for raising and lowering. </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> |
