PREFACE

Over the past few months, AUE has conducted several exploration dives on 
numerous deep wrecks off Cape Canaveral where we have noted abundant 
accumulation of ivory tree coral (Oculina varicosa).  This species of 
deepwater coral, stark white in color, forms extensive "thickets" on the 
benthic features known as pinnacles or cones from just south of Ft. Pierce, 
to well north of Daytona off the east coast of Florida.  It can be found 
sporadically elsewhere, including as far north as North Carolina, however, 
the abundance off the central east coast of Florida, known as Oculina Bank, 
is unparalleled anywhere else on the planet.  Unfortunately, Oculina Bank 
has been seriously impacted, with perhaps 90% of the coral habitat 
eliminated.  Recent evidence indicates that the source for this destruction 
is illegal trawling activity.

Ongoing research and restoration efforts conducted by NOAA, Harbor Branch 
Oceanographic Institution (HBOI), and Florida State University have studied 
this most important species and the habitat it provides.  The Oculina 
thickets support numerous species such as snapper, tilefish, gag, scamp, 
snowy grouper, and amberjack, which, in turn, support important recreational 
and commercial fisheries.  Unfortunately, the destruction of habitat will 
undoubtedly have a similar impact on the associated fisheries.  However, 
efforts to restore the natural habitat are being pursued.  Material such as 
concrete slabs and reefballs, each seeded with sprigs of live Oculina, have 
been deployed in hopes of jump-starting the repair of Oculina Bank.  This 
coral  restoration project is as unique as the Oculina coral itself, in that 
it is one of the only projects where the exact cause of destruction is known 
(as compared to tropical coral diseases and bleaching).

In the past, the source of this transplant coral has originated from 
submersibles, ROVs, and dredges.  Collection efforts have been frustrating, 
as getting sufficient amounts of the coral in good shape has proved 
difficult.  Knowing that the deep wrecks off Canaveral provided discreet 
sample locations where sufficient coral could be collected, AUE readily 
volunteered our services�

THE DIVES

We were fortunate to again have the vessel "Reel Time" to support our dive 
activities.  Captain Tony is one of the most enthusiastic and accommodating 
captains I have had the pleasure of meeting.  In fact, he had recently 
manufactured and installed a brand new dive ladder on the boat, an action I 
considered amazing since he has stated that we will be the only group diving 
off his boat.  The use of his boat and his talent really makes for an 
enoyable trip.  We were joined by our sponsor and the Principal 
Investigator, Dr. Chris Koenig (FSU), as well as one of Captain Tony�s 
fishing buddies who turned out to be former NASA shuttle astronaut, Bruce 
Melnick (STS-41, STS-49).  Bruce had heard about our antics from Tony and 
really wanted to check out our operations.  I think all of us were blown 
away that a former astronaut considered what we do as cool!

After loading the boat up early Saturday morning, we departed Port Canaveral 
towards our first dive on the "Oculina Wreck," otherwise known as the 
"Fuggedaboudit Wreck."  This unidentified wreck sits in approximately 305 
feet, with the main deck around 285 feet, and has only been visited one time 
by a couple of AUE divers.  This would be my first visit to the wreck, and I 
was looking forward to trying and identify the sunken vessel.  As we pulled 
up to the site, it appeared that the surface current was only 1.5 knots.  
However, we would soon learn that appearances can be deceiving.  After we 
deployed our hook and shotline, the trio of divers geared up and prepared 
for our drop on the ball.  We all would have scooters so we anticipated a 
very easy dive, given the moderate surface current.  Once in position, we 
all piled through the tuna door and motored down.  The surface waters were 
pretty murky, but I soon saw my other two buddies flash past me in the other 
direction.  I soon gave chase, dumbfounded that we had already been swept 
past the shotline.  Apparently, the wind had slowed down the drift of the 
boat, as the current just under the surface was still moving along at a 
brisk pace.  After motoring for a while in a shallow descent, I became 
disenchanted with our "progress."  I aimed upwards to get a glance at how 
far we were from the ball, eventually breaking the surface and finding 
ourselves still far downcurrent of the float ball.  I saw the futility of 
continuing and signaled the boat for recovery.  As the boat turned in my 
direction, the other guys popped to the surface and "cut in line" to be 
picked up, so I enjoyed floating around a bit before boarding the boat.

After discussing the situation for a moment, we opted to drop in directly on 
the ball on the second attempt and go hand-over-hand to the bottom to insure 
we hit the wreck.  After repositioning, we all piled in and began the long 
descent to the wreck below.  Around 180 feet, amberjack showed up to escort 
us to the bottom as we passed into darker and cooler water.  Around 270 
feet, I could see Mikey�s HID light touching down on the wreck ahead, as I 
observed the wreck appear underneath me.  The obtuse and wide bow passed by, 
outlined in the white Oculina coral.  As we all set down, we went to work on 
a nearby thicket attached to the deck.  After deploying one of our high-tech 
coral bags, we quickly fractured the coral colony into manageable pieces and 
placed it in the bag.  This deeper specimen had the consistency of a thin 
pretzel and was easily broken with bare (gloved) hands.  With the bag 
quickly filled, we attached a liftbag and sent the collection to the 
surface.  I decided that with the time elapsed on the long descent and coral 
collection, that we deserved to investigate the wreck a bit.  I was also 
still a bit tired from the workout pulling down the line (time to hit the 
gym!) so I looked forward to a leisurely swim around the vessel.  With 
perhaps 20 feet of gloomy visibility, we started to slowly swim aft.  
Oculina appeared to adorn every available surface, with only a random whip 
coral the only other prominent benthic species.  It appears that the wreck 
is a large freighter, perhaps 300 feet in length.  She is sitting upright 
and has settled well into the muddy-sand seabed.  As we turned the dive and 
headed back towards the hook for our departure I observed a fascinating 
artifact.  Settling down on the deck, I picked up a spent 88mm brass shell 
casing.  After the first visit to the wreck, the divers thought that the 
wreck may be pretty old, perhaps turn-of-the-century; however, with this 
find it appears that it may be a World War II casualty.  I did not notice 
any deck guns on the wreck, though we did not make it back to the extreme 
stern.  Reaching the shotline, I remained adjacent to the deck, holding the 
line pinned against the wreck to facilitate the removal of the hook.  I 
could barely make out the glow of my buddies light who were less than 20 
feet below me as they pulled the hook loose from some blown out hull 
plating.  They efficiently removed the hook and rose to foul it as we 
drifted alongside and off the wreck.  After raising the hook a little more 
off the bottom, we proceeded to complete our decompression.  We were 
eventually joined by a curious three-foot long Atlantic sharpnose shark that 
poked around for the shallow portion of our deco.

We boarded the boat to discuss the dive with the others and find that Chris 
was happy with our gift we sent him.  We were amazed to find out that 
several red barbiers (Hemanthias vivanus) and roughtongue bass 
(Pronotogrammus martinicensis) were found in the coral by the crew.  These 
small fish are very abundant around the coral and utilize it as a refuge 
from predators.  While Chris was ecstatic, we all felt like we skimped a 
little with the amount of coral, especially considering it took us perhaps 
two minutes to complete the task.  We all knew that our second dive on the 
Cities Service Empire (CSE) would allow much more time to collect a 
sufficient amount of coral and would be an easier dive � at least we thought 
it would be�

On the way to the CSE I took the opportunity to talk at length with Bruce.  
We traded stories, with me fascinated with his shuttle missions and space 
exploration, and he equally interested in our exploration dives.  I found it 
funny that as I generally tire of talking about diving, I tried to control 
the discussion and learn about some of the cool stuff Bruce has done.  
However, Bruce apparently has tired of talking about his space exploits just 
as much, and he tried to keep the subject on diving.  We eventually both 
recognized this and got a good chuckle about it.

Upon reaching the wreck, a few of the guys tried their hand at fishing.  
Unfortunately, the recent ground swell that murked up the water earlier in 
the week had really put off the bite and success was limited.  We eventually 
deployed the shotline after judging the current was approximately 1 knot.  
We anticipated the same effect as found at the other site, but figured with 
the massive size of the CSE and shallower depth, we would have no problem 
hitting the wreck with the scooters.  As we lined up at the door, Tony 
motored the boat adjacent to the ball and we hit the water.  I was first out 
the door and upon splashing I was tossed a bit by the churning wake behind 
the boat.  I felt something bang into my legs and at first thought I was 
pulled under the boat and was worried that I might impact with one of the 
screws so I quickly balled up.  However, I then saw Mikey motor past me and 
realized that he had just banged into me upon entry.  Greatly relieved, I 
began to give chase when I noted the tow harness had gotten wrapped on my 
collection gear.  Holding onto the shotline, my other buddy came over and 
helped with the tangle.  After the quick fix, we proceeded to scooter along 
the shotline, slowly making our way into darker waters.  Around 180 feet, 
someone turned out the light.  I could faintly make out an HID light in 
front of me, but it appeared like a little brown dot.  I eventually saw the 
wreck when I touched down on the deck at 210 feet, though with *maybe* five 
feet of brown visibility I had no idea where on the huge wreck we where.  To 
complicate things, the current was strong along the top deck and we had to 
keep gunning the scooters just to stay in place.

I managed to touch down on the wreck and brace myself, whereupon I saw a 
compass that I had observed on an earlier dive.  This luckily provided me 
with an exact location on the wreck.  I knew there was a massive Oculina 
cluster nearby and I tried to communicate this to my buddies.  I eventually 
stumbled across the cluster and lassoed my scooter to a piece of wreckage.  
The other guys got in position and I whipped out the collection bags.  I 
decided to pull myself over to the other side of the cluster in order to 
avoid crowding the other guys.  Once in place, I proceeded to do my best 
Jackie Chan imitation on the coral.  This thicket was perhaps seven feet 
across and as I worked I would occasionally pop up to look over at my 
buddies.  Dark shadows and two muted lights were the only confirmation that 
they were busy working also.  While working, I laughed to myself as I 
realized the bottom temperature was the same 77 degrees as the surface 
waters � at least one thing was nice about the dive!  Unlike the coral at 
the deeper wreck, the branches on the CSE were very dense and crowded, which 
made it harder to break off large pieces from the cluster.  However, we soon 
completed in filling both bags and reunited to rig them with liftbags.  Once 
we shot the bags to the surface, I tumbled over to the scooter and joined 
the other guys so we could find to hook.  While we had planned for a longer 
dive, due to the miserable conditions we elected to bug out early.  Mikey 
managed to find the hook and we worked to pull it off the wreck.  I managed 
to notice a few of the vertical bulkhead supports -- appearing like spooky 
trees in the murky vis -- actually oscillating due to the current flowing 
over the wreck.  Perhaps this attributes for the advanced deterioration of 
the upper decks of the wreck.  After freeing the hook, we tried moving off 
the wreck though we couldn�t really tell where we were or where we were 
going due to the soupy water.  We fouled the hook and then made our way to 
the surface.

Boarding the boat, we found a very happy PI with two coolers full of coral.  
Chris stated that this is the most coral he has collected in the past five 
years using any other method (i.e., submersibles, ROVs, dredges).  With the 
amount of coral obtained, he felt he could easily restore several hundred 
acres of habitat.  Pleased with the success of the trip, we all enjoyed the 
ride back in as the sun slipped over the horizon.

Unfortunately, the weather on Sunday took a turn for the worse and our 
planned dives on the Pan Mass and CSE were scrubbed.  However, Chris felt 
that he had enough coral to easily supply him for the upcoming deployment 
cruise in a couple of weeks.

Pictures of the dives should be added to the AUE website shortly.

Cheers,
Mike
