Initial deep diving survey and
imagery of intact 1800’s-era sailing vessel
Geographic
Region: Dry Tortugas, Florida

Country/Countries of Destination: USA
Ultimate Destination: 19th century
ship wreck of unknown sailing vessel
Approoximate bundaries: Classified |
Description:
The wreck lies in a soft silt bed at approximately 220/fsw,
in U.S. territorial waters. Future goals, with the
information gathered from this expedition, are to develop a
10-year summer excavation plan partnering with one or more
major universities and/or museums.

Purpose/Objectives: Captain Tim Taylor was the first person
to dive this wreck in October of 2004, at the behest of a local
fisherman who had drug up a piece of copper sheeting (part of
the hull) while trawling and shared his find with a salvage
company. The salvagers completed a week of initial side scan
sonar imagery on the site and wanted a video survey. After a
solo bounce dive to 220 feet on air, Tim recorded enough video
and retrieved a small brass port which allowed them to arrest
and claim the site with the admiralty court. R/V Tiburon, Inc.
returned with mixed gas and rebreathers in December 2005 for a
quick video survey that led to the belief that the vessel is
from the early to mid 1800’s era. Deemed of no commercial value
by the salvage company, the site was donated to our non-profit
Ocean Outreach Inc. so that we could carry out a long-term
archeological project with a national university and/or museum.
Our first step in this long -range project was to photo document
the site with the intention of having Dr. John Broadwater assess
its historical significance. This initial information would
allow us to seek funding and form strategic partnerships for a
long-term project. All indications are that we have found an
intact time capsule in diving range that provides a rare
opportunity for exploration. We plan to model this after
terrestrial academic archeological programs and engage graduate
and post graduate students in working the site every summer
season. The winter months will be spent preserving, cataloging,
researching, and planning the next year’s project. The end
results could be an underwater archeological site at 200 plus
feet deep that is fully excavated, documented, and displayed.

Itinerary and
routing (locations, transportation, and subsistence
arrangements):
The entire
operation was run from the Research Vessel Tiburon (R/V Tiburon)
based out of Key West, Florida. Owned and operated by Tim
Taylor, FN04, the vessel is 63 feet long and equipped to sleep
14, plus 5 crew. She is a USCG certified and SOLAS-rated vessel
which specializes in research and outreach projects.
Departure
Date: May 30, 2006
Return
Date: June 05, 2006
Departing Key
West, the Tiburon made way to the anchorage of the Dry Tortugas
National Park. We based operations from this location and
motored each morning to the wreck site.
Challenges:
Depth and
location - the wreck lies in 220/fsw and requires technical
divers doing staged decompression diving with limited bottom
time and restrictive repetitive diving sequences. This limited
the dive teams to 1 dive per day and a range of bottom times
from 20-40 minutes, with a run time of just over an hour to
about three hours, respectively.
Archeological
integrity - with a strong desire not to disrupt the site and
provide the highest level of integrity to the process for
historical purposes, some of the possible methods of wreck
identification – which include removal of artifacts, scraping,
digging into the site - were off limits. High definition video
was deployed to provide subject matter experts and divers the
experience of seeing the wreck from topside and remote locations
to assist in identifying key factors of the site without
disrupting current conditions.
Limited
resources - With a small team of four working divers, there
was a limited amount of time available to accomplish work each
dive day.
Accomplishments:
9 dives of
two-diver teams to a depth of 200+ feet over the course of
six days for a total diving time of 34 hours, 36 minutes; bottom
time total of 7 hours, 48 minutes
Daily breakdown as
follows:
5/29/06 day 1 diving: 1 dive of
two divers for 97 min each
5/30/06
day 2 diving: 2 dives of two divers each for a total of 171mins.
(79 and 92 each, respectively)
5/31/06
day 3 diving: 2 dives of two divers for a total of 246 min (176
and 70 each, respectively)
6/1/06 day
4 diving: 1 dive of two divers for 172 min each
6/2/06 day
5 diving: 1 dive of two divers for 154 min each
6/3/06 day
6 diving: final dive day; 2 dives of two divers each for a total
of 198 min (77 and 121 each, respectively)
Initial
analysis of footage by Captain Hare and the dive
team contributed to the following preliminary assessment of the
wreck site:
Although the
desired goal of identifying the wreck was not accomplished, we
were able to broadly document the primary hull structure and
debris fields. We also came to some first conclusions which will
need to be verified, narrowing down the likely period of
building into the late 19th century, possibly 1880s-1890s. This
somewhat contradicts the previous 2004 expedition results in
which the dating of artifacts, including glass bottles, seemed
to indicate a potential mid-19th century (1850s-1870s) period,
based on the bottle manufacturing processes used. Further study
by additional experts of the site and artifacts will hopefully
provide more conclusive dating of the wreck. The successful
collection of video footage provided the raw resources to create
a video mosaic which thus enables the production of a detailed
visual map for future reference. Sketches of the primary hull
structure enabled a broader visual overview of the decking and
locations of specific attributes of the wreck site. The overall
video production of the expedition both topside and below should
prove a valuable asset for further evaluating processes and
accomplishments.
The likelihood
of properly identifying the correct bow and stern orientations,
(which was previously not clear based upon the position of the
rudder on the wreck site), seems to have been clarified to
indicate the bow is to the west and the stern to the east. This
is still to be finalized.
Clear
identification was established for the “rear” mast
(approximately 3 feet in diameter) at 20’ from the stern, with a
possible rake to the stern of maybe 15 degrees. Some divers felt
they saw the rake clearly, while others were not as certain.
Aft and forward
of the exposed wreck site are indications of a cargo of
hardwoods; a sample was retrieved for further analysis. There
were a large number of bronze pins that were used to build the
upper hull structure, which has since deteriorated. In
addition, an abundance of bronze plates with pins were
identified as the pieces that held the upper decks in place.
Mid-ship is
covered with shrimp boat nets and long-line gear, making it
impossible to currently identify the position of the center
mast, but it would appear to be mid-ship at approximately the
50’ mark of the 111’ length of the hull section. The beam runs
just under 30’ at the center of the wreck site.
The rudder
components, three specific parts all oriented on or near the bow
section of the wreck, should yield additional information that
may help to further narrow down the period of shipbuilding. The
largest rudder component lies in the sands on the starboard side
of the wreck and still has intact wood parts that made up the
rudder assembly.
Along the
starboard side of the wreck is a large metal tube that is
surmised to have been around the mast. The length is
undetermined as it is buried into the sand. It is approximately
2-3’ in diameter and is the home to an especially large black
grouper.
The recovery of
a bottle (champagne) may provide additional details in respect
to the dating of the wreck and will be forwarded to a bottle
expert for analysis of the period of the bottle’s manufacture.
Initial survey
of the debris fields off the main hull indicate there is
little-to-no debris in the northeast quadrant of the wreck site;
there is a small collection of rigging components and copper
sheeting in the sands to the north by northeast area of the
debris fields; more significant debris in the east and southeast
sections of the site. The southwest quadrant of the site remains
largely uninvestigated; however, the previous visit had
identified a portion of the port running light just off the
southern side of the wreck site and there may be additional
debris worth review.
Sand sweeps were
made about 100-150’ out from the primary wreck site, but due to
the cursory nature of this effort, provided little information.
Objects are well buried in the sand and silt and there is
minimal visibility, ranging from 10-20’, due to the fine silt
bottom. Objects identified in the debris fields are many metal
“horse collar” pieces that would be used to manage the sails on
the masts and boom arms. In addition, 4-6’ poles (likely iron)
also used to manage the sails of the ship were found in a
concentration in the easterly and southeasterly areas.
The general
consensus of the on-board subject matter experts indicate this
is likely to be a barge or barq of the late 19th century,
possibly of American or Caribbean shipbuilders. Previous
assumptions were that it might be of European origin; however,
this seems less likely based upon the potential later dating for
the ship. Authoritative conclusions await further analysis and
study. [artifact pictures]
Successful
deployment of safe, deep-wreck diving procedures and processes
by a small, efficient team :
The entire team
came from varied backgrounds and disciplines. Of immense value
was Captain Dave Hare, who provided extensive knowledge and
history on maritime practices and ship building history. Dave’s
ability to provide insight into potential artifacts and ship
building timelines enabled us to fully utilize the HD video
footage that was shot each day and provided the team with a
detailed accounting of the things we were seeing and recording.
It allowed us to create a detailed plan for the following day’s
diving, as well as further focus on questions posed during the
reviewing of the footage. The structured video review by the
subject matter experts provided the dive team with focused
objectives and assisted the team in narrowing down the tasks for
each day’s diving. Basic operational processes were tested and
will be optimized for future expeditions, including the staffing
of functions and capabilities required to accomplish the goals
of the expedition.
Successful implementation of video in
situ, with pod-casts production concept also initially
executed. Over 40 hours of high quality video footage was
captured.

Crew Logs/Observations

Daily Dive Operations -
All deep exploration and shallow support diving requirements for
Trimix, Heliair, EANx, Sofnolime scrubber, and air were provided
by R/V Tiburon, Inc. One rigid, inflatable boat (RIB) along
with surface support of RIB pilot, safety diver, and
videographer (when required) provided support for each dive.
Support aboard the Tiburon included boat captain, diving safety
officer, lookout, videographer, and stand-by safety diver.
Diving equipment consisted of Inspiration rebreathers (CCR),
Twin 100 and 95-cubic foot tanks open circuit (OC) SCUBA, travel
gas tanks, decompression tanks, bailout tanks of 80, 63, and 40
cubic feet, regulators, diving gauges and computers, as well as
laptop computers with decompression and gas blending software,
and many other items provided by individual team members or out
of ship’s store. Safety divers used 80 and 63 cubic ft. tanks
with standard SCUBA configuration.
Breathing gas selections for deep diving were as follows:CCR-
Heliair 10% oxygen/50% helium (10/50) used on set point of 0.7
and 1.3 with bailout tanks of 14/33 and 50/50 in 40 cubic ft.
aluminum tanks carried by each diver
OC - twin steel tanks of 100 and 95 cubic ft. were used. Each
diver carried as well one 80 cubic ft. aluminum tank with 32%
oxygen for a travel mix and one 40 cubic ft. tank with 100%
oxygen for decompression. The final mission dive was conducted
with a 63 cubic ft. aluminum tank in place of the larger 80
cubic ft. travel gas tanks.
Each team conducted one dive per day. CCR run times were 123 to
180 minutes; OC run times were 68 to 76 minutes. Average bottom
times of 30-40 minutes for CCR and 20-22 minutes for OC were
planned and executed.
Safety divers primarily used 21% NITROX (air), with an EAN25
used on one day.
Additional emergency decompression of 60% was available from
RIB/safety diver.
Estimated total gas used during the Expedition dives were 650
cubic ft. of oxygen and
700 cubic ft. of helium.
Captain David Hare
David holds a 3,000-ton Oceans Masters license, commercial jet
pilot’s license, and is a SCUBA diver and businessman. With two
circumnavigations under sail and over 125,000 ocean miles, David
has a substantial background in worldwide sailing exploration.
Currently David is the Captain of a Delta expedition yacht –
Thunder - based in Fort Lauderdale. As the son and grandson
of wooden sailing boat builders, David has had a life long
passion for the sea and especially for 19th century Baltimore
Clippers. As the previous Master of sailing vessel LYNX, (an
1812 privateer replica designed by Melbourne Smith), Hare was
excited to join the expedition as the co-captain in search of a
here-to-for unexplored sailing wreck. His in-depth knowledge of
shipbuilding brought an added dimension of expertise to the
project.
Having two captains on board also allowed Captain Taylor the
opportunity to dive on the wreck without worrying about onboard
ship activities. Captain Hare’s responsibilities consisted of
getting the Tiburon to and from the dive site and ensuring that
a ‘watch person’ was consistently monitoring the divers
throughout their two-three hours of decompression stops. During
this time, the vessel slowly circled the divers as they floated
underwater with the current.
Doug Rice, CC rebreather diver
The wreck:
Returning to the site 18 months after our initial dives to
“discover” the wreck was a great luxury. To have reviewed seeing
the site in one’s mind for months leading into years –
the “magic” came into play when the artists’ renditions combined
with our video transects and footage to confirm the “vision” I
had built in my mind’s eye from the pervious dives. In my mind,
I had imagined a great history for this vessel; she was cruising
the open seas for months at a time, making the transatlantic
passage between Europe and the Americas, and moving with the
winds through history over the great international trade
routes.
So it may be … but it seems more likely she was a hard working,
robustly built barge that moved lumber and materials from place
to place, perhaps in long hauls - perhaps in short runs, but
maybe not quite as glamorous a history as I had fantasized.
Despite the small let-down, it was an outstanding experience to
dive a virgin wreck in deep waters, piecing the parts of an
archeological puzzle together to uncover the story of a vessel
lost at sea.
The dives:
Undertaking long deep dives is as exciting as it is challenging;
the “40 minute” dive exacts a harsh penalty of a long
decompression. It takes about 4
minutes to get down to the 220’ depth, thus leaving us 36
minutes of bottom time exploring the wreck site. The journey
back to the surface from the bottom begins with the first
decompression stop at about 150 feet. One hangs on the down
line, trying to embed each image and impression of the dive into
one’s mind. Then you check-in with your dive partner, making
sure all systems are “go” for the long ascent to the surface.
The process continues with stops along the way, each getting
progressively longer until you reach the final 20-foot stop. At
around 50 feet, we are greeted by the safety diver and the
comfort of knowing we are back in the realm where everyone else
is. Shortly after dropping off some of our gear with the safety
diver, we prepare to leave the down line and do a drifting
decompression, where the boat will follow us as the currents
move us through the blue water. As we drift along, we continue
to maintain our depth to assure a safe and clean decompression.
It has taken over an hour and a half to get to that 20-foot
stop, so close to the surface, the warmth of the sun and the
comfort of your bunk for a nice long nap. Thankfully,
the water temperature has warmed from the slightly cooler
71 degrees on the bottom to a balmy 81 degrees as you reach the
last stop. Despite the water temperature rising as you ascend,
your core body temperature has begun to drop and you feel the
chill through your bones during your final decompression stop.
The 20-foot stop lasts for almost 70 minutes, a period where
you just hang in the blue, drifting under your lift bag. At
times, we got really lucky … when we were joined by a small pod
of six dolphins playing in the afternoon sun, or a small Silky
shark which would often come to visit us for a while as we
floated through his neighborhood of the ocean. Other times, we
would simply see nothing but blue and the small little creatures
that make up so much of the ocean’s mass. I entertain myself by
watching minute colonies of plankton and jellyfish floating
through the water column, imagining for this little jellyfish
that his journey really is a lifetime, where mine only has to
last another 70 minutes until I break through the ocean surface
and feel the warmth of the sun again.
