Royal Park Bridge – April 30, 2016

Water Temp: 73° F
Max Depth: 77 ft.
Start Time: 8:55 am
Dive Duration: 46 min.
Weather: Mostly Sunny
Wind: ESE @ 11 mph

Air Temp: 77° F
Current: N @ <.25 kts
Visibility: horiz. 40 ft.; vertical 40 ft.
Seas: 2 ft., occasional 3 ft.
Boat: Deep Obsession
Lat/Long: 26°47.687/80°01.049

   The goal for this dive was to obtain a fish count and video benthics.   
   Royal Park Bridge Reef is made up of 15,000 tons of concrete, along with a 50’ tug, a 130’ and a 70’ barge. The concrete material was from the old Royal Park Bridge and deployed between 2000 and 2001 in 80’ of water.
   The varying rubble piles make great habitat for a large number of species and it seems to be holding up very well. The three fish counters identified over 68 different species, including Goliath Groupers and a Reef Shark that must be a normal resident because we saw one the last time we dove this site on March 7th, 2015. There is also great benthic growth and inverts on this site.
   The Team dropped in on upside down bridge tender house, noting these invertebrates: branching vase, azure vase, algae hydroids, bulb tunicates, star encrusting, pink lumpy, white condominium and black tunicate. The shear volume and diversity of sponges was absolutely amazing. A large stingray with its tail/stinger cut off was noted off in the sand.
   Per Captain Jim Harris, the drop coordinates were 80°00.033/26°47.630, since the team GPS unit was malfunctioning.

 

Larsen's Valley – April 30, 2016

Water Temp: 72° F
Max Depth: 75 ft.
Start Time: 10:42 am
Dive Duration: 41 minutes
Weather: Mostly Sunny
Wind: ESE @ 11 mph

Air Temp: 77° F
Current: N @ <.25 kts
Visibility: horiz. 40 ft./ vert. 40 ft.
Seas: 2 ft, occasional 3 ft.
Boat: Deep Obsession
Lat/Long: 47.240/00.745

   The goal for this dive was to obtain a fish count and video benthics.
   Larsen’s Valley is a natural reef consisting of a shallow valley running between the low relief ledges. The Team dropped in a little further south than we normally do, so a lot of the reef was covered with sand. As we progressed up the reef, we noted an abundance of Algae hydroid & Dictyota as the dominant benthic species on the reef. Lavender rope sponge, barrel sponge, and elephant ear covered with algae hydroids were spotted. A few hard corals were present, and a low quantity of fish species. Maze coral, Brain coral, Montastraea cavernosa, and Siderastrea siderea were identified on the reef. A few deep water sea fans were observed. Lots of sponges including brown variables, pink lumpy, lavender rope, and small barrel just to name a few. A large Sand Tilefish was noted swimming above the sand. Per Captain Jim Harris, the drop coordinates were 80*00.745/26*47.240, since the Team’s GPS unit was malfunctioning.
