   The goal for this dive was to obtain fish counts and video benthics on RBM and for map team to find and map Flagler Bridge Site 1.
   This site is made up of materials from the old Riviera Beach Marina pilings and docks. It has been deployed in several stages beginning in 2011. Material from the Flagler Bridge demolition was placed near this site in January of 2016.
   The map team went east from the site about 9 minutes from the drop point to look for the new Flagler Bridge material, but found nothing but sand, so returned back to the eastern edge of RBM where they swam north along the eastern side.
   The fish counters did their stationary counts on RBM as well as roving counts. A Goliath Grouper was noted, and a Wahoo was spotted near the surface. A Sea Cucumber, Bridled Goby, and a school of around a thousand Scad were also noted on the dive. Three Lionfish were eradicated. It was also noted that about ¼” of sand covers most of the flat surfaces on this site.


Flagler Bridge Sites 2 & 3 – November 20, 2016

Water Temp: 76° F
Max Depth: 54 ft.
Start Time: 10:52 am
Dive Duration: 26 min.
Weather: Sunny
Wind: N @ 13.8 mph

Air Temp: 72° F

    The goal for this dive was to map the site, obtain fish counts and video benthics.
    The team did a drop looking for Flagler Bridge Site 2 but found nothing but sand. After about 15 minutes of searching they surfaced to have the dive boat drop them on the coordinates for Flagler Bridge Site 3. On the site of Flagler Bridge 3, they found the material and proceeded to do their assigned tasks.
   The mapping team did a perimeter of the site, noting that the material is sinking into the sand about 3’. At the far north east side there are two large pillars standing up about 15’ into the water column.
    There was mild surge on this dive. Fish counters identified several Scorpionfish, Blue Cornetfish, Yellow Jacks, tiny 3” Tomtates, two White Margates and a couple of Sea Cucumbers. Ten Lionfish were eradicated from the site, and another was noted.
