Greetings all…. Dive season is
here… Yeah!!!!!!!
This past weekend Mel, Matt,
Lisa & me travelled up to Fort
Weatherill for a season opening
dive & BBQ. Although the weather
was ominous, the dive gods
smiled upon us. As we arrived in
Jamestown, RI the rains stopped
and the parking lot was empty.
We were greeted by excellent visibility and sunny skies. Lots of interesting cold water jellies.
Though the water hovered near
50 degrees, we enjoyed a good
35+ mins dive, and an excellent
meal afterward.
Our April meeting went well
with a good turnout. Capt Noel
shared recent footage of a recent
trip to the Maldives. Our featured
speaker for May is Lisa “Shark
Girl” Jarosik, who will being sharing photos and video clips of a
recent trip aboard the Carib
Dancer to the Bahamas.
In lieu of annual clambake, on
Sat June 6th, Mel Rich has helped
organize “Thrill of The Grill” night.
Festivities planned to start around
7 pm at the cottage. Please respond and bring some things for
grilling or feasting. Rumor has it,
there may be a Karaoke Machine.
If you have not yet returned
your reasonable membership dues
for 2015, they are needed. Additionally, we are in serious need of
a Club Secretary to help organize
the newsletter. No experience
We are still looking for speakers for July & November. Additionally, Sept is Members Present and
we are looking for 3 short presentations, so if you have a cool
photo or video clip you would like
to share please let Matt or myself
know.Stay cool, get wet and have

First warm-blooded fish identified
by Michael Winter
Cold fins, warm heart? Strange but true, scientists
In a discovery that defies conventional biology, a
big fish that lives deep in the Pacific Ocean has been
found to be warm blooded, like humans, other mammals and birds.
Researchers from the National Oceanic and Atmospheric Administration (NOAA) determined that unlike
other fish, opah generate heat as they swim and distribute the warmth throughout their entire disc-shaped
bodies by special blood vessels. Special "countercurrent heat exchangers" in their gills minimize heat
loss, allowing the deepwater predators to keep their
bodies several degrees above the water temperature
250 feet down.
"There has never been anything like this seen in a
fish's gills before," said biologist Nick Wegner, the lead
author of the report.
Though some species of fish can temporarily warm
their swim muscles, including tuna and some sharks,
"whole-body endothermy" has distinguished mammals
and birds from fish and reptiles, which draw heat from
their environments.
"The opah appears to produce the majority of its
heat by constantly flapping its pectoral fins, which are
used in continuous swimming," Wegner toldLive Science.
His colleague Heidi Dewar toldThe Washington
Post, "I think that it's really exciting that we spend so
much time studying especially these larger fish to find
something that's completely unique and has never
been seen before in any fish."
Their team's findings are published in the May 15
issue of Science.
Also known as the moonfish, the opah averages
100 pounds, has a diameter of 3 feet and can grow to
up to 6 feet long. While deepwater fish are slow moving because of the cold, the opah's warm-blooded
uniqueness results in faster swimming, better vision
and quicker responses, giving it an edge in the survival sweepstakes.
"Before this discovery I was under the impression
this was a slow-moving fish, like most other fish in
cold environments," said Wegner, of the Southwest
Fisheries Science Center in La Jolla, Calif. "But because it can warm its body, it turns out to be a very
active predator that chases down agile prey like squid

fish found to be warm blooded.
and can migrate long distances."
Opahs, which don't swim in schools, are regularly
caught either by longline fishermen from California
to Hawaii to New Zealand seeking tuna or unintentionally in commercial driftnets.
An old fish tale held that opah brought good luck,
NOAA says, so fishermen would give the colorful
catch away rather than sell it. But times and marketing have changed, and food fetishists are increasing
demanding it for its "rich, tasty meat."
Two years ago, recreational anglers in Southern
California caught a 125-pound opah during a rockfish outing. The "mystery fish" put up a 45-minute
fight, leading the captain to think it was a shark,
GrindTV reported.

Lionfish Safety:
What To Do If
Stung by Divers
The business listed on this page has donated
dive gear and dive services to help support the
Fairfield County Diving Association.
Alert Network
Lionfish are typically nocturnal
and docile creatures. They allow
curious divers to approach closely,
enhancing their risk for injury from
accidental contact or handling of
marine life. These ornate, elite
predators are an invasive species
that have become a common sight
for many divers as they spread
down the North Atlantic, and into
the Caribbean and northern part of
South America’s Atlantic shore.
Lionfish use venom as a protective mechanism. When divers
come in direct contact with their
spines or fins, venom is injected
into the skin through needlelike
bristles located along the dorsal,
pelvic and anal fins. Envenomations are rare and often not lifethreatening, but benefit from rapid
first aid response and professional
medical evaluations.
These puncture wounds can
cause pain which may last for several hours. They also may result in
rapid edema (swelling caused by
fluid retention) and subcutaneous
bleeding. Swelling typically clears
in two-to-three days, while the tissue discolorations can last up to
five days. In some cases, swelling
can become so severe that blood
flow is compromised leading to
ischemia (inadequate blood flow to
a part or organ) and tissue necrosis (tissue death). This is particularly true for fingertips, where
swelling could significantly compromise the flow of blood. A secon-
dary complication may result in
the wounds becoming infected.
First aid is essential in preventing infections; clean the
wound, control the pain and apply topical antibiotics using these
easy-to-follow steps:
Wash the area thoroughly with
soap and fresh water.
Remove any foreign material.
Control bleeding, if necessary.
Control the pain: Immerse the
affected area in the hottest water
tolerable without causing injury
(the upper limit is 113°F / 45°C)
for 30 to 90 minutes. Repeat as
needed. Test the water on the
same area as the injury to ensure
it is not too hot; intense pain
may impair one’s ability to discriminate between hot and scalding.
Ice/cold packs can also be used
to provide relief and reduce swelling
Apply topical antibiotic ointment
or cream.
Apply bandaging as needed.
If necessary, administer paincontrol medications.
Seek a professional medical
evaluation as medical management
may include sedatives, tetanus
vaccination and antibiotics. Advanced life support may be required in rare instances.
In the event of an emergency,
call 911 (or the local equivalent)
and the DAN Emergency Hotline at

Rare Spanish Shipwreck From 17th Century
Uncovered Off Panama by Jane J. Lee
Archaeologists searching for
real-life pirates of the Caribbean
stumbled on a mysterious shipwreck in 2011. Now after years of
historical detective work, they
know what they discovered.
In 1681, the Spanish merchant
ship Encarnación sank during a
storm near the mouth of the Chagres River on the Caribbean side of
Panama. Built in Veracruz, Mexico,
the cargo vessel was part of the
Tierra Firme fleet, the economic
lifeline of 17th-century Spain.
Though it sank in less than 40
feet of water, the Encarnación
somehow escaped major looting
and is surprisingly well-preserved,
with the bottom half of its hull intact thanks to burial in the seafloor. (Learn about a cursed warship that's also been stunningly
well preserved.)
The Encarnación gives a rare
glimpse of a major shift in world
history during the colonial era,
says Filipe Castro, a nautical archaeologist at Texas A&M University. "It is the rise of capitalism,

imperialism, rationalism, and the
middle classes that are going to
buy art and consume literature."
At the time, gold and silver
mines in Mexico and Peru fed the
ambitions and coffers of Spain's
royal family. To transport the
wealth of the New World to
Europe, Spanish colonists built
fleets of merchant vessels that
were escorted by armed galleons
and warships, explains Fritz
Hanselmann, an underwater archaeologist at Texas State University.
After delivering their treasures
to Spain, the fleets would turn
around and, laden with European
goods, hopscotch throughout the
Spanish colonies selling their
Spain's two main fleets, the
Tierra Firme and the New Spain,
serviced Central and South America and Mexico, respectively.
"These ships were the backbone
of the Spanish colonies," says
Hanselmann, who is part of the
team studying the Encarnación.
Oceanic Lifeblood
The Encarnación is one of about
16 Spanish shipwrecks discovered
in the Americas, says Jennifer
McKinnon, a maritime archaeologist at East Carolina University who
is not involved in the study. But
nearly all the wrecks found to date
have been heavily looted. Ocean
bacteria and shipworms that feed
on exposed wood usually consume
what looters miss.
“Thus we know very, very little
about 17th-century Spanish shipwrecks," McKinnon says.
To find a wreck with much of its
cargo still onboard, as well as part
of its hull intact, can provide a
wealth of new knowledge. "Ships
that were built hundreds of years
ago didn't come with blueprints,"
Hanselmann says. Studying the

(Continued from page 6)
Encarnación’s hull has already
helped reveal how these vessels
were constructed.
An initial examination revealed
the use of a material called granel,
a kind of permanent ballast, says
Chris Horrell, a maritime archaeologist working with Hanselmann.
It's "basically a cement consisting
of sand, lime, and pebbles," he
explains, that shipbuilders used to
coat a ship's hull with a thin veneer.
Researchers think granel stabilized ships and was also used as a
construction material for buildings
throughout the New World. Horrell
is not yet sure whether granel was
a New World invention or an Old
World import, but finding out is
part of his research agenda.
An Accidental Find
Hanselmann and colleagues didn't set out to find the Encarnación.
They were looking instead for
ships belonging to the notorious
English privateer and pirate Captain Henry Morgan, a legendary
figure who at the height of his
power commanded a fleet of 36
ships and more than a thousand
In 1670, 11 years before the
Encarnación went down, Morgan
was on his way to sack Panama
City when a storm sank five of his
ships at the mouth of the Chagres
River. Hanselmann and his team
were searching for those ships
when they found a surprise.
Sensors that detect magnetic
anomalies alerted the researchers
to the presence of metal objects
about 0.6 miles (a kilometer) from
the mouth of the river. Divers sent

to investigate discovered a shipwreck loaded with cargo—an indication that it probably wasn't one
of Morgan's ships. "If he's en route
to sack a city, his holds aren't going to be full," says Hanselmann.
Further investigation revealed a
merchant ship instead. "These
ships were the ones the privateers
were always after," says Hanselmann.
The Encarnación didn’t carry
flashy cargo like gold coins or silver cups, says Horrell. But its
workaday materials were valuable—both to pirates and now to
