Cayman Brac - What a Trip!

--by Daryl Johnson

Eleven ADA divers enjoyed what many are calling the best international trip the club has done in recent years! Dan and I had been to Cayman Brac many years ago and a few hurricanes visited the island since we had been there. We knew the diving was spectacular but what we didn’t know is that the resort had been almost completely rebuilt and also recently remodeled. But what was really amazing is how accommodating all of the staff were at the resort- from the dive operations all the way to the front desk. We had an all inclusive food package and the food was terrific at all three meals every day.

Speaking of the dive operations, they had three large Newton dive boats which are great to begin with but they also did “valet diving” so that once we handed them our gear we never had to lift it for the rest of the trip. We would simply take our fins and masks to platforms at the rear of the boat and they would bring the rest of the gear to us and help us get it on. And they really worked had to make sure that the dive site we went to had the best visibility and lowest current available. All of the divers did the 12 dives that came with the trip but Rachel and John Davis are the “iron divers” of the trip with a total of 19 dives for the week.

There were lots of photos taken and if you visit  our FaceBook page you can see the photo album  with all of the terrific pictures. It will be hard to top this trip for next year but if you have a place in mind send it to me at and it will be added to our list to check out as we plan for 2017.

Close to Home: The Beauty of Boynton Beach

--by Rachel Davis

ADA divers may have noticed the location of Boynton Beach showing up on the dive schedule more frequently this year. We have three dives planned for Boynton Beach - including one coming up over Labor Day weekend on Saturday, September 3rd.

Situated half-way between Fort Lauderdale and West Palm, Boynton Beach is still relatively undiscovered and the sites are far less visited than many South Florida dive sites. The reefs of the Boynton and Delray Ledges systems are in pristine condition, hosting an impressive bio-mass of fish and other sea creatures including sharks, eels, turtles, and rays. In fact it's not uncommon to see pods of dolphins following alongside the boat. If your captain is nice enough, he may even stop the boat and let you snorkel around with them, as we did recently with Starfish Enterprise charters.

Dry Tortugas National Park - Part 2
--by Jerry Kosakowski

You may have wondered how I previously wrote about the Dry Tortugas and there was no mention of diving. Well there is diving, but not on any of the trips to Fort Jefferson. There is snorkeling there however. Diving in the Dry Tortugas has to be done properly by liveaboards.

There are several that make the trip. The diving is pristine and the lobsters are huge because of the distance from the mainland.

A cold front in 1976 came thru it wiped out 96 \% of the branching corals. Most of the park is now patch reefs. Lionfish have also added to the parks diving problems. However that is being addressed by management.

The club has made several trips to the park but none lately and none are planned that I am aware of. So, you are on your own to discover and report what your experience has been. The boats require permits to dive here so it should be spectacular. Do it and tell us about your experience.

The Secrets of Sea Creatures that Change Color

--by John and Rachel Davis

While diving Boynton Beach recently on the 4th of July we noticed a flounder on the sandy bottom. We almost didn't see him because he was so well camouflaged. His body was exactly the color of the sand, complete with subtle brown speckles. We observed him move a few feet away into a bed of algae, where his body color miraculously changed to a deep green hue to match the algae-covered bottom. He disappeared into the algae as effectively as he had disappeared into the sand. This change was immediate. So we began to wonder how these amazing creatures are able to change their body color so perfectly and rapidly. This article is our attempt to understand what causes this miracle of nature.

"Many thousands of color-changing cells called chromatophores just below the surface of the skin are responsible for these remarkable transformations. The center of each chromatophore contains an elastic sac full of pigment, rather like a tiny balloon, which may be colored black, brown, orange, red or yellow. If you squeezed a dye-filled balloon, the color would be pushed to the top, stretching out the surface and making the color appear brighter—and this is the same way chromatophores work. A complex array of nerves and muscles controls whether the sac is expanded or contracted and, when the sac expands, the color is more visible. Besides chromatophores, some cephalopods also have iridophores and leucophores. Iridophores have stacks of reflecting plates that create iridescent greens, blues, silvers and golds, while leucophores mirror back the colors of the environment, making the animal less conspicuous," per Fox Meyer, Smithsonian National Museum of Natural History.

So now that we understand how they change color, we then wondered how do they know what color to become in order to camouflage themselves?

"To produce these changes within the skin cells, light stimuli is received through the eyes at the retina and passed through nerves to specialised skin cells. The colouration is a response to the ratio of reflected to incident light directed at the retina, and is generally a mix of the inputs from both eyes. While a flounder with one eye is still able to change colour effectively, a fully blind flounder cannot simulate the background in shade, colour or pattern." Dan Bayley, MarLIN at the Marine Biological Association.

We have also observed this phenomenon with octopi in Belize, as well as with groupers in the Cayman islands. Octopi can change their texture as well as their color for more effective camouflage. Here is a link to an amazing video of an octopus that is perfectly camouflaged on a coral head. He turns bright white when he is startled by the diver. Watch it here.

Diver's Safety Sausage
- Part 1
-- by Lon Von Lintel

The purpose of the safety sausage is to make diver's location visible from long distances on the  surface.  Many boat captains and/or dive shops require all divers to carry this devise for good reason.  A diver's head bobbing in choppy seas is very difficult for boat crews to locate at long distances.  All agree that being visible not only allows your boat to find you, but remember, other boaters need to see you as well.  Being struck by other boaters is a real and present danger.  But there are so many choices to choose from, which is best and how much do they cost?  I am glad you asked. First thing to consider is size.  Yes size does matter is this case. Length should be at least 6 feet.  The objective is to elevate something visible above the waves.  If the waves are 3-4 feet, then a 6 foot devise is needed.  Next consider width.  I recommend at least 9 inches.  Again bigger is better.  Colors range from yellow to green to orange. My experience tells me yellow is best.  Prices range from $20-$30 for a simple oral inflated no frills devise.

Next time, Diver's Safety Sausages part 2


Shark Junction
--by Kiana Sein, Mast Academy 10th grade

Photos taken on a GoPro

At 2:30pm, just 10 minutes off the sandy beaches of the Bahamas we arrived at our destination, Shark Junction. Our group consisted of 10 guests, 1 camera man, 2 safety divers, and at last 1 shark feeder.

The visibility underwater was at its finest as I made my way down 45 feet. Greeted by more than 15 Bahamian Reef sharks I swam to the feeding area. It is very important to keep your movements slow and steady in order to create a safe environment for you and the sharks. While observing these magnificent creatures, I noticed that some had hooks on their mouths. This was one of the most incredible dives I have yet experienced. It helped me clearly understand how harmless sharks can be.

ADA has created a unique concept in local diving: NO FAULT INSURANCE!! For an additional $5.00, per person, per local dive trip, members can eliminate the worry of losing their dive fees because of an unforeseen change of plans. If for any reason you are unable to attend a local dive for which you are scheduled and have paid the insurance, ADA will credit your dive fee to another date. The $5.00 insurance is  non-transferable and non-refundable. When you make a reservation, ask for dive trip cancellation insurance.


All members are reminded to read the “Rules & Guidelines for Diving Activities” you received with your membership package. Number 16 states, “All divers must be present for the pre-dive briefing”. If the diver is not present for the entire briefing, diving privileges may be revoked for that dive. Please plan to arrive on time - or better yet - a bit early. We thank you and appreciate your cooperation.


Because of our contractual agreements with our service agents - dive shops and boat captains, we must notify them - usually seven days in advance - of the final number of spaces we are paying for. Thus, if our members cancel less than seven days in advance, we regret that NO REFUND OR CREDIT can be given, unless trip cancellation insurance has been purchased at the time of the dive trip payment (see next news article!)
