<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In order to extend the benthic habitat map to waters deeper than 20 m, 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, Warsaw Hole, Dry Tortugas, Tortugas Ecological Reserve, and Riley's Hump. This shapefile contains the first coordinate of the drift, benthic habitat information, general relief category, presence/absence of coral, 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. A Trimble Pro XR Differential Global Positioning System (DGPS) was used to obtain sub-meter accuracy locational data for all video collected. To accurately geo-locate every frame of video, DGPS coordinates were stamped, along with UTC time into every frame using a Horita video labeling device.</SPAN></P></DIV></DIV></DIV> |
