Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In the first six years, we chose to adopt a sampling protocol that focused on habitat interfaces (i.e., areas where coral reef meets seagrass/algal plain), using randomly selected, permanent transects. The area within and outside the Reserve was divided into three strata: 1) the existing Dry Tortugas National Park (DTNP, Park), 2) the Reserve (not falling within the existing jurisdiction of the DTNP), and 3) a 5 km buffer around the Reserve not within the DTNP (Out) for before/after comparisons (a Before-After Control Impact (BACI) sampling strategy (Underwood 1991). Lines were drawn through the longest axis of the Tortugas Bank and DTNP, normal to the prevailing northwest-southeast currents and bisecting these features into areas facing either upstream (North) or downstream (South; Fig. 1). In conjunction with the Reserve, Park, and Out strata, the interface zones along both of the large reef structures in Tortugas North (Tortugas Bank and DTNP) were designated as one of six categories: 1) Out North; 2) Out South; 3) Park North; 4) Park South; 5) Reserve North; and 6) Reserve South. We then used bathymetry to expand our sampling to reef and bank edges throughout all of the desginations. Paired band transect visual censuses were made by divers over the reef and soft bottom habitat along the 30 m transects conducting fish counts were made within 1 m on either side of the permanent transect. These methods also included using video then to collecting in situ images every meter that were later analyzed for benthic cover using CPCe.</SPAN></P></DIV></DIV></DIV>

A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V 510 equipment. All raw data streams are transferred to the office for downloading and processing in CZMIL's Hydro Fusion software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid and have the withheld bit set. PFM_ABE software then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID12B model and exports valid lidar data as a series of unclassified LAS files.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>These data are served to the public at the following NOAA site:</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>https://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=6330</SPAN></P><P><SPAN /></P></DIV></DIV></DIV>

Description: <DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN><SPAN>In Summer 2015, National Oceanic and Atmospheric Administration (NOAA) Center for Coastal Fisheries and Habitat Research (CCFHR) division contracted Geodynamics services for a complete processing and reviewing of multibeam sonar data collected on the NOAA Ship Nancy Foster (NF) and Thomas Jefferson (TJ) from the years 2004-2016. The seabed elevation and acoustic imagery data (backscatter) were collected using multibeam echosounders (MBES) on the respective ships. The data were preliminary processed and corrected for motion, sound speed, and other major artifacts before assessment by Geodynamics. However, the data were only semi-cleaned, contained various artifacts, and converted with the real-time tide. Therefore, Geodynamics was contracted to complete a full review of the data and apply a NOAA zoned definition file (ZDF) to permit CCFHR’s later use of the data for characterizing Florida Keys National Marine Sanctuary (FKNMS) and adjacent areas bottom habitats. The corrected bathymetry base surface will be used to interpret the seafloor topography habitat types and extend the range of existing habitat map products that were created by manual interpretation of satellite imagery. The acoustic imagery (backscatter) aspect of the data will help further this interpretation. However, Geodynamics was not responsible for processing backscatter data but were responsible to ready the backscatter data for eventual processing. This version of the FKNMS Digital Atlas also contains multibeam data collected on the NOAA Ship Nancy Foster during the summer of 2018, and multibeam data collected in 2018 around the Marquesas on small vessels under contract to NOAA, OCS.</SPAN></SPAN></P></DIV>

The parameters for the EM2040 and the 710 were set to operate in Medium CW and Very Shallow mode respectively. Watercolumn data was logged with the EM2040 only, since there was some interference between the EK60 and the EM710 while the two units were being used simultaneously. The swath angles for both sonars were set to 64 degrees on starboard and port side, unless sea conditions or depth determined a narrower beam swath would improve coverage. Preliminary cross line analysis was used to develop adaptive line plans in Hypack for all multibeam surveys. Multibeam data were processed in near real-time to produce preliminary maps of bathymetry and backscatter.</SPAN></SPAN></P><DIV><DIV><P STYLE="margin:0 0 11 0;"><SPAN /></P></DIV></DIV></DIV>
