Reef Farmers
-- by Daryl Johnson
Diver Planting Coral

On September 6, 2014, the Active Divers Association (ADA) received training and participated in a coral reef restoration dive with the Coral Restoration Foundation in Key Largo, Florida. A classroom session was conducted at the CRF facilities. Divers gained familiarity with the mechanics of growing and planting corals and with the tools needed to perform the various delicate operations.

Once the divers learned how to do the coral restoration activities above-water, it was time to take their new-found skills to the ocean. The first dive consisted of harvesting and planting staghorn coral in the CRF nursery. A second dive followed to attach the harvested corals on a nearby reef. In all, 50 new pieces of coral were planted. See a related story on the coral reef initiative below.

Fiji Dive/Cruise Vacation Update

--by Daryl Johnson

Four ADA members have signed up for the Fiji trip and were able to take advantage of early booking discounts we were able to secure to date.There is still space on the ship for both divers and non-divers, although the price will vary over time. The ship, the Reef Endeavor operated by Captain Cook Cruises out of Australia, is a small cruise ship ideally suited for navigating the waters off the Fiji Islands.

I will continue to keep the pricing information and other details updated in the trip briefing on our ADA website page located at Fiji.html. If more ADA divers show interest in the trip, I may be able to negotiate an additional discount. If you have any questions contact Dan at dmbaeza@bellsouth.net or Daryl at diverdaryl@bellsouth.net

Southeast Florida Coral Reef Initiative

--by Roy Wasson

Coral Tree

The Active Divers Association supports the Coral Restoration Foundation's work in restoring the reef eco-system in south Florida. In addition to ADA’s role in supporting the mission of the Coral Restoration Foundation, there are numerous other opportunities for us to help preserve and restore Florida’s coral reefs.  I recently was invited to attend a monthly meeting of the South Community Working Group of the Southeast Florida Coral Reef Initiative (“SEFCRI”) held at Nova Southeastern University’s Oceanographic Center in Dania Beach.  Below is an overview of that initiative.

In 2000, the U.S. Coral Reef Task Force (USCRTF) adopted a National Action Plan to conserve coral reefs. With guidance from the USCRTF, the Florida Department of Environmental Protection and the Florida Fish and Wildlife Conservation Commission coordinated the formation of a team of interagency and non-agency marine resource professionals, scientists, resource users and other stakeholders. This SEFCRI Team, first gathered in May 2003 to develop local action strategies targeting coral reefs and associated reef resources from Miami-Dade, Broward, Palm Beach and Martin counties to improve the coordination of technical and financial support for the conservation and management of coral reefs. SEFCRI is targeting this region because the coral habitats are close to shore and co-exist with intensely urbanized areas that lack a coordinated management plan (like that of the Florida Keys National Marine Sanctuary)

The SEFCRI Team is comprised of four focus teams, each responsible for addressing one of the four focus areas of concern: 1) Awareness and Appreciation; 2) Fishing, Diving and Other Uses; 3) Land-Based Sources of Pollution and Water Quality; and 4) Maritime Industry and Coastal Construction Impacts.

SEFCRI focus teams have identified issues and threats to coral reefs and have developed and are implementing Local Action Strategies (LAS) for their component of the SEFCRI. This includes defining and revising goals, objectives and actions, priority setting, budget development, building implementation teams and tracking progress. Numerous stakeholders participated in the development of Florida’s LAS, using a facilitated process including public review and input. The outcome is a coordinated plan to address causes of coral reef degradation and provide a roadmap for successful conservation and management.

Caribbean Reef in Paradise Meets Sanford & Sons

Author’s Name Intentionally Withheld
(currently in the witness protection program)

Sign

As you may recall, this year’s international diving adventure took us to Bonaire in the Netherlands Antilles.  It is a diver’s paradise with crystal clear water, 100’+ visibility, and lots of fish and coral.  About a dozen of us were fortunate enough to be able to go on this July 2014 trip, planned by our adventure dive aficionados Daryl Johnson and Dr. Dan Baeza.

This article is not about how great the diving was, the pristine reefs, the abundant sea life and the great people on the trip.  Yes, it was an absolutely fabulous trip, but that’s a story for someone else to tell.  This story is about a particular reef dive a few of us took one afternoon off the dock of the hotel in Bonaire.

Just north of the hotel resort was the pier dock.  It is a relatively small pier where the cruise and cargo ships dock.  As the sign says … “It is Strictly Prohibited to Dive Near or Under a Cruise or Other Ship While Docked, at the North Pier”.  So I won’t say we did that, and I won’t even admit to being on the dive, but I will say that some of us were curious to see what the reef looked like near the pier, so off we went.

Bonaire is breezy and sunny year round, and it hardly ever rains.  But, just as we were ready to jump off of the dock it began to rain.   Fortunately, it never rains underwater, so everyone jumped into the water and we started the dive.  Initially, the reef was beautiful, just like the reef we dove a couple of days earlier in the southern direction.  However, the closer we got to the pier, the more it changed.  Initially, the water was crystal clear, and the reef dive started off with coral, and fish, and sponges.  But the reef quickly transitioned to crystal clear water with tires, old timber pilings, a boat or car motor, assorted pieces of unidentifiable objects of all sizes, and a whole lot garbage that probably had been pushed off of the pier for decades.  It was

a bit surprising, especially since Bonaire is surrounded and protected as a National Marine Park.  The sky above and the water became darker...... and then there was a low pitch “rumbling” sound in the water.   It was really creepy. All that was missing was the “shark” music from the movie “Jaws” and a couple of underwater sniper “frogmen” in hot pursuit shooting at us.  To increase our discomfort, we had been diving for a few days, so the 82 degree water was becoming a cold to some of us.  Cold, dark and kind of creepy was the dive, with a touch of Fred and Lamont Sanford to describe the underwater junkyard.  It was an interesting departure from the beautiful pristine reefs of the days before and after.

Twenty minutes out, twenty minutes back, and we were at the dock again and out of the water.  It was time for a lukewarm shower and a quick nap before dinner. Another day in paradise!

Continuing Education: Enriched Air Diver - Nitrox

-- by Rachel Davis, PADI Open Water Scuba Instructor

Enriched Air, better known as Nitrox, is a special gas mix that contains an oxygen percentage higher than that of air. Technically nitrox is any enriched air mix from 22% to 40%, although the nitrox mixes most practical for recreational diving range between 32% and 36% oxygen.

Nitrox provides the diver several benefits, the most important of which is an extended bottom or no-stop time vs. air diving. Nitrox is most beneficial for dives with extended depths between 60-90 feet. For example, the no-decompression limit for a diver on air at 90 feet is 25 minutes, compared to 40 minutes for the same diver on 36% Nitrox. It is especially beneficial for repetitive diving over many days such as on a liveaboard. The presence of additional oxygen in the mix reduces nitrogen build up in the tissues that could lead to decompression illness. Many divers report feeling less fatigued after diving when breathing nitrox vs. air, especially for repetitive dives.

However, there are certain hazards associated with Nitrox that do not exist with air diving. Breathing excessive oxygen at depth can lead to oxygen toxicity, a rare but serious illness. For this reason there are strict depth limits for diving with Nitrox, which are determined by the percentage of oxygen in the mix. Enriched Air Diver certification is required to use Nitrox, and the class teaches important safety considerations and practices while using Nitrox.

The PADI Enriched Air Diver course is strictly a classroom session and does not require diving. Contact your local PADI professional to sign up for a course, or visit the PADI website at https://www.padi.com/scuba-diving/padi-courses/course-catalog/enriched-air-diver-course/for more details.

The General Hoyt S. Vandenberg Wreck in Key West
--by Rachel Davis

Key West is a fun vacation spot anytime of the year, but over Labor Day weekend, the bars on Duval Street seem a bit wilder than normal, with the revelers taking advantage of the “two Saturday nights” that weekend. It seemed a fine time for John and Rachel Davis to visit Key West, and no visit would be complete without diving the Vandenberg.General Hoyt S Vandenberg

She lies seven miles south of Key West in 140 feet of water, at 510 feet, 10 inches in length, edges out the Spiegel Grove by a mere 10 inches. She was sunk in 2009, but unlike the Spiegel, the Vandenberg sank according to plan and landed upright. The seas over Labor Day weekend were rough, and we waited until Monday morning for the best conditions, but still bucked out to our morning double-dip in 3-5 foot seas. We anchored at mid-ship and explored the back half during the first dive. We found the swim-through satellite dish and managed the moderate current. Fortunately, there was plenty of railing to hold on to. The two huge aluminum satellite dishes are hallmarks of the Vandenberg, but are gradually succumbing to five years in salt water and are now half their original size. I had a piece literally break off in my gloved hand.

For the second dive the Gulf Stream came in and vastly improved the visibility, while also picking up the current. Here we explored the front half of the ship, swam through the bridge and around the bow. But the most amazing thing here was the huge 30 by 40-foot American flag, which formerly flew at a Morris, Illinois, Memorial Park for Sept. 11, and donated to the Vandenberg on July 4th of this year. It was the largest flag I had ever seen up close in my life.

We highly recommend South Point Divers http://www.southpointdivers.com/, who were very safety conscious and took excellent care of us. Key West has so many tourist attractions to explore such as our favorites the Hemingway House, the Butterfly Conservatory and the Coast Guard Cutter museum, but the Vandenberg should be at the top of every diver’s list

Is Barbados in your future??
--by Daryl Johnson

If you go on the 2015 ADA Caribbean dive trip it will be!!! Situated on the outer reaches of the Eastern Caribbean in the Lesser Antilles, Barbados is a unique mix of British influence and West Indies flavor.  At one time Barbados was known for sugar production, but tourism has taken over as the main economic influence. As the natives like to say “Life didn’t start here but it was perfected here!”  Planning and research has already started and we expect to get some more definitive information out there by January. But, go ahead and pencil in July 18-25, 2015,so you don’t miss out on another great diving adventure trip!

Scuba Tips and Tricks
--by Lon Von Lintel

MASK FOGGY, CAN'T SEE?  NO FUN!!Common, de-fog liquids purchased at your dive shop, many times do not work as intended. Why?  You apply just as instructed, and still the mask fogs. The problem is a thin layer of oxidants, usually silicon from the mask skirt, that is deposited on the inside of the glass. This oxidant often starts during the manufacturing process and continues to form over time

Your de-fog liquid cannot do it's job if anything is coating the glass. The solution is to remove the oxidant with an chemical agent designed to dissolve the oxidant. A much more practical approach is to scrub the mask with a mild abrasive such as toothpaste or a household cleaner. I use Softscrub or Comet.  Yes, both will produce microscopic scratches on the glass, but you will never see the scratches, nor do they affect your vision.  Just apply a bit of either cleaner or toothpaste to the inside glass, add a few drops of water, and scrub for a few minutes with a piece of paper towel.  I usually do this every 3 to 6 weeks or 5 to10 dives, whichever comes first.

Rinse well. Then before your dive, apply defogger as usual.  Problem solved !!

Shore Diving in South Florida - North Commercial Blvd
--by Jerry Kosakowski

Last month we talked about diving south Commercial Boulevard. This month, we again visit Commercial Boulverd,  only this time, the north side. The parking has been cut back drastically by townhouse construction, although there still remains public parking one block north of Commercial. Nearby are restaurants and bars including Aruba, a restaurant that is an excellent choice for an after-dive meal right on the beach. Enter the dive location and you may swim in either direction, north or south. The reef is one large reef line and the same in both directions. No need to go to the second reef from here. Just continue north while zig-zagging east and west, then turn around and head south to complete the dive. There are no lifeguards at this location. It is a popular dive spot for beginners and those who are earning their C-cards via shore diving. I did some of my advanced open water certification work at this location. During the lobster season this is popular with the shore divers.  At one time I lived two miles from this location and caught my share of lobster here. It was my favorite and I hope it becomes one of yours.


Fish Identification Series - MarineAngelfish
--Source: Wikipedia: http://en.wikipedia.org/wiki/Pomacanthidae

Marine angelfish are perciform fish of the family Pomacanthidae. They are found on shallow reefs in the tropical AtlanticIndian, and mostly western Pacificoceans. The family contains seven genera and approximately 86 species. They should not be confused with the freshwater angelfish, tropical cichlids of theAmazon Basin.

With their bright colours and deep, laterally compressed bodies, marine angelfishes are some of the more conspicuous residents of the reef. They most closely resemble the butterflyfishes, a related family of similarly showy reef fish. Marine angelfish are distinguished from butterflyfish by the presence of strong preopercle spines (part of the gill covers) in the former. This feature also explains the family name Pomacanthidae; from the Greekπομα, poma meaning "cover" and ακάνθα, akantha meaning "thorn".

Many species of marine angelfishes have streamer-like extensions of the soft dorsaland anal fins. The fish have small mouths, relatively large pectoral fins and rounded to lunate tail fins. The largest species, the gray angelfish,Pomacanthus arcuatus, may reach a length of 60 cm (24 in); at the other extreme, members of the genus Centropygedo not exceed 15 cm (5.9 inches). A length of 20 to 30 cm (7.9 to 11.8 inches) is average for the rest of  the family. The smaller species are popular amongst aquarists, whereas the largest species are occasionally sought as a food fish; however, there have been reports of ciguatera poisoning
Next Column >>

as a result of eating marine angelfish.

The Queen angelfish, grows to be 45 cm (18 in). With neon blue and yellow scales, with iridescentpurple and orange markings, surprisingly it is not conspicuous, and actually hides very well, and is very shy. The larger species are also quite bold and seemingly fearless; they are known to approach divers. While the majority adapt easily to captive life, some are specialist feeders which are difficult to maintain. Feeding habits can be strictly defined through genus, with Genicanthus species feeding on zooplankton and Centropyg epreferring filamentous algae. Other species focus on sessile benthic invertebrates; sponges, tunicates, bryozoans, and hydroids are staples.

Most marine angelfishes restrict themselves to the shallows of the reef, seldom venturing deeper than 50 m (160 ft). The recently described Centropyge abei is known to inhabit depths of 150 m (490 ft). They are diurnal animals, hiding amongst the nooks and crevices of the reef by night. Some species are solitary in nature and form highly territorial mated pairs; others form harems with a single male dominant over several females. As juveniles, some species may eke out a living as cleaner fish.

Shark Week Disappoints
--by Lon Von Lintel

The Discovery Channel's recent program about sharks generated many negative comments from viewers around the country. The following are several, in part, sent to the editor of Dive Training Magazine: "each year it seems to grow increasingly worse", "What should be an opportunity to educate the public is passed up for the ratings", "Pathetic attempt to help us understand the truth about sharks" ,"The most positive development about Shark Week is that fewer people watched it", "For those of us who are weary of Discovery Channel's inferior portrayal of sharks. a 9 million viewer drop in one year is most encouraging". My opinion echoes all of the above and I watched the first night, hoping my skepticism would be unfounded. But alas, I too was disappointed and never watched again.
