ADA Dive-Cruise Just Around the Corner

If you signed up for the first Annual ADA Dive Cruise it means in just a few days (November 14th) you will be boarding the Emerald Princess  at Port Everglades. If you haven't signed up but interested in going, contact the trip leader, Daryl Johnson at diverdaryl@bellsouth.net or 954-591-1161 for more information.

Just a few reminders:

  • Bring your C Card!
  • Bring Your Passport!
  • All rental equipment is provided except for wetsuits, which may be rented at the shops. So bring some cash with you if you think you will rent one.

Late Breaking News:
$50 onboard credit per cabin for the ADA Group

We will meet on November 14th in the Explorer Lounge on Deck 7 at 6:30 PM for a short meet-and-greet round of introductions. I think most of us are doing anytime dining, so we can disperse from there to our choice of restaurants. There are a lot of optional excursions that may fit the schedules of divers and non-divers; so this would be a good time for you to see if someone has an interest in joining you on an excursion.

See you on board!

Coral Reefs Revealed

--by Juliana Bach, 9th grade Maritime student at MAST Academy

There are 2 types of Coral Reef Formations in the world: Tropical Coral Reefs and Deep Water Coral Reefs.  Most of us are familiar with the Tropical Coral Reef formations, i.e. Barrier Reefs, Atolls and Fringe Reefs.

(Deep Water Coral Reefs are a relatively new discovery and will be discussed in another article)

BARRIER REEFS: Everybody knows at least one famous barrier reef so-named because at its shallowest point it can create a “barrier” that ships cannot pass through. Barrier reefs are parallel to the shore and are separated by a lagoon. The Caribbean is home to the second largest barrier reef.   It is called the Meso-American  Reef and runs off the coast of Belize.

ATOLLS are a roughly circular oceanic reef system surrounding a large central lagoon.  Atolls occur when a fringe reef forms around an island. When the island sinks into the ocean or the sea level rises, the fringe reef becomes an atoll reef.  Atolls occur mostly in the Pacific Ocean.  However, there are some sinkholes, essentially vertical caves, in the Caribbean. The most famous is the Great Blue Hole, located near the center of Lighthouse Reef off the coast of Belize.

FRINGE REEFS are the most abundant type of reef in the world.  If you are on a snorkeling trip, it is most likely on a fringe reef. Fringing reefs are reefs that grow directly from shore. Fringe reefs don’t have a lagoon to buffer freshwater runoff. Therefore, they are particularly sensitive to pollution and sedimentation.

PATCH REEFS occur inside fringe reefs.  They are small isolated reefs that grow from the bottom of the island platform or continental shelf.  Patch reefs differ in size and usually occur between fringing reefs and barrier reefs1

Identifying reef types is not always as simple as suggested above.  This is especially true in the Caribbean where some of the fringing reefs are separated from shore by open water. Next time you go on a dive, ask yourself: Are the reefs off the coast of South Florida fringing reefs, barrier reefs or something else?

Cook What You Catch: Linguine with White Clam Sauce

--by Daryl Johnson

Okay, so once again you are not likely to catch any clams while diving in South Florida but this dish is so simple and good that every seafood lover should have this in their recipe book. The minced clams are cheap, loaded with protein and store for a long time in cans so you can keep them handy for when you need to come up with a spur of the moment healthy gourmet dinner.

The fact that this recipe uses very few ingredients means that each one needs to be of very high quality and the dish will only be as good as what you put in it, so pay attention to what you use. Here is a list of ingredients:

  • Two 6.5 oz. cans of minced clams
  • Two cloves of fresh garlic finely chopped (see my cooking hack!)
  • One quarter cup extra virgin olive oil (EVOO) -Use olive oil that says “first press” or “cold pressed” and use a good brand. I like Bertolli   and Trader Joe’s.
  • One tablespoon chopped parsley
  • One tablespoon chopped basil leaves (see my cooking hack!)
  • Dash fresh ground pepper- I like course ground from a pepper mill
  • Six oz. whole wheat linguine- I always like to use a whole grain version or you can use a quinoa based pasta
  • One tablespoon of butter
  • Fresh grated parmesan cheese- my favorite brand is BelGioioso which is just as good as the imported varieties costing twice as much. Stay away from store brands as they just don’t have the flavor you want.
  • Dried oregano to garnish

Hermaphroditic Life of a Fish: Are You a Boy or Are You a Girl?

--by Dr. Dan Baeza

We all think that absent surgery and hormone therapy, the equipment you’re born with is the equipment you’ll always have. Not so true with fish. There are several species of fish, notably certain wrasses, parrotfish, gobies, clownfish, eels, and groupers, among others, that can changes from female to male, or male to female. The process is called sequential hermaphroditism and like everything else in nature, is designed to maintain the survival of the species.

Was Nemo a boy or a girl?

Normally, schooling fish organize in hierarchical groups with a single dominant male and several females in the school, referred to as a harem. Because of the high mortality rate of hatchlings, mostly due to being eaten by predators, females can lay hundreds or even thousands of eggs during a spawning period. The eggs must be fertilized by a male during the reproductive cycle. Males generally can produce sperm almost at will, while females will take a lot longer to produce eggs. To eliminate contention among several alpha males for dominance, only a single male gets to be the Romeo for all the harem’s Juliets.

So, why would a fish change its sex? Well, in the fish-eat-fish underwater society, sometimes the dominant male dies, either from old age, disease, or as a snack for a larger predator. When that happens, the herd must get a new male to assure survival. At this point, generally the largest female will undergo a hormonal process to become the dominant male. The process will take several days, after which the fish is a fully functioning male, with no visible aftereffects or the need for psychotherapy.

Occasionally, a male will change into a female if the harem suddenly finds itself with more than one male. Although most fish only change one time, some are able to change back and forth between male and female several times. Indeed, some fish can simultaneously be both male and female, Talk about an identity crisis!

By the way, lest you think this process is solely the purview of fish, some corals routinely change sex. Even certain birds, reptiles, and amphibians, can sometimes change sex when conditions are right. Nature is truly amazing!

What Exactly Are the Seven Seas?
From worldatlas.com

Some ancient civilizations used the phrase “seven seas” to describe the bodies of water known at that time. The ancient Romans called the lagoons separated from the open sea near Venice the septem maria or seven seas. Most current sources state that "seven seas" referred to the Indian Ocean, Black Sea, Caspian Sea, Adriatic Sea, Persian Gulf, Mediterranean Sea, and the Red Sea.

Not all geographers agree on this list of seven, believing that the seven seas reference will be different depending upon the part of the world and the time period in question. Some geographers point to the Age of Discovery and suggest that the seven seas represent the Atlantic, Pacific, Arctic, and Indian Oceans, as well as the Mediterranean Sea, the Caribbean, and the Gulf of Mexico. Other geographers state that the seven seas were the Mediterranean and Red Seas, Indian Ocean, Persian Gulf, China Sea, and the West and East African Seas.

Today we recognize more than 50 seas worldwide. A sea is defined as a division of the ocean which is enclosed or partially enclosed by land. With that said, the Caspian Sea, Dead Sea, and Aral Sea are actually saltwater lakes, because they lack an outlet to the ocean. Conversely, by this definition, the Gulf of Mexico and Hudson Bay are seas.

Interesting Sea Facts:

  • The largest sea is the Bering Sea at 876,000 sq. miles or 2,270,000 sq. kilometers.
  • The saltiest sea in the world is the Red Sea with 41 parts of salt per 1,000 parts of water.
  • The warmest sea in the world is the Red Sea, where temperatures range from 68 degrees to 87.8 degrees F depending upon which part you measure.
  • The coldest seas are found near the poles such as the Greenland, Barents, Beaufort, Kara, Laptev and East Siberian Seas found near the north pole and Weddell and Ross Seas found in the south poles. The Baltic Sea is also considered one of the coldest seas.
  • Depending upon the amount of salt in the water, sea water freezes at about 28 degrees F. High salt content lowers the temperature for freezing and low salt content raises the temperature for freezing.

Pufferfish

--by Jerry Kosakowski

Pufferfish (some species are also called toadfish) have been given the title ‘Most Poisonous Fish’ and have also been labeled the second most poisonous vertebrate in the world. The toxin responsible for ranking this fish so high in the “danger zone” is called tetrodotoxin. Tetrodotoxin is neurotoxic and inhibits neural transmission leading to weakness, paralysis, and even death at relatively low concentrations (~2mg). This toxin is found in the fish’s liver, ovaries, intestines and skin, leaving muscle tissue with relatively low and somewhat safe levels to eat. However, only highly trained and certified chefs are allowed to prepare this fish for consumption; a common practice in Japan where pufferfish are considered a delicacy.

Why Dives Get Cancelled
--by Lon Von Lintel

On at least 4 occasions this year, ADA Safety Officers have canceled dives. Why? The are several reasons for this. Understanding all of the reasons will help our membership avoid confusion and disappointment.

  • Mechanical problems- with boats or dive equipment such as compressors.
  • Boat crew family emergencies- no one available to drive the boat.
  • Limited u/w visibility- can make dives unpleasant and even dangerous.
  • Large waves- making dives unpleasant or dangerous.
  • Severe weather warnings- such as tornadoes.
  • Boat sinkings- yes, this actually happened. Several years ago, American Dream was rammed and sank while tied to the dock. We now dive on American Dream II in Ft. Lauderdale.

So the moral of this story is ALWAYS CALL LON at 30-251-4975 FOR A WEATHER CHECK AND DIVE STATUS UPDATE. For afternoon dives, call between 9 AM and 10 a.m. and you will never be misinformed. This vital information needed to make a decision is not available before 9 a.m. because the dive boat operator will have not yet reported ocean conditions for the morning dive. If you call after 10 a.m. chances are no one from ADA will be available to take your call. Remember, we can't call you due to the large numbers of divers involved.  So, 30 seconds of your time to make the call may save you hours of driving time and a lot of gas money.

My First Dive
--by David Goldberg

My first dive took place so long ago, my instructor’s PADI number was MXLVI. When the big day arrived, I was ready as ever: Quarter-inch wetsuit, check. Regulator consisting of a only one hose, check. (In those days, we buddy-breathed through the one good regulator.) My safety equipment consisted of a snorkeling vest with a CO2 cartridge. There was no pressure gauge or J-valve on my tank.

Most New York divers are introduced to the sport at a location 2000 yards off the shore of Jones Beach, Long Island. As we approached the dive site, I wondered if I had the courage to throw myself into the black, cold, and polluted waters of my home state. Little did I know that this fear would be dwarfed by the Herculean task of squeezing myself into a quarter inch wetsuit on a small rocking speedboat.

After suiting up fully, I was insanely uncomfortable. I couldn’t wait to throw myself into the water. In I went. Soon, I was 30 feet under, amazed at the glorious 5 foot visibility surrounding me. I didn’t actually see anything noteworthy, but none of that mattered. This was my childhood dream, 10 years in the making, now realized.

Until this day, I cannot remember anything other than the complete sense of satisfaction from having survived my checkout dive. That sense of childhood wonder and nostalgia is still as visceral, and always comes flooding back whenever I think of my first dive.

Shallow versus Deep
-- by Lon Von Lintel

Several years ago, I was diving; shore based, in the Maldives. I was buddied with a guy from Germany who was an excellent, experienced diver.  We did all the scheduled  boat dives and also many beach dives which were a shallow reef and then a vertical wall.  It seems Europeans typically like deep diving, given the option.  When we planned our first beach dive, he assumed we would do at least 100' (30 meters)

I finally convinced him to try 20' with long bottom times.  He  agreed and after our fist dive he remarked, "Wow, I had no idea we could see so much more in shallow!"  That brings me to some points to ponder.

Advantages of shallow water

  1. Longer bottom times- an hour or more vs 20 minutes at 100'
  2. More light/color- all red, orange and yellow are absent at 100'.
  3. Safer- out of air is a minor problem at 20', major emergency at 100'.
  4. Safer- decompression sickness is not possible at 20', at 100' it is.
  5. Easier navigation- from 20' you can surface for boat check, then continue dive, not so from 100'.
  6. Warmer- thermoclines occur in deeper water, plus wet suits compress with depth and lose insulation properties.
  7. See more- 80 percent of marine life lives in shallow water.
  8. See more- many corals do not thrive in deep water.
  9. Everyone welcome- junior divers, inexperienced divers, students, occasional divers, resort course divers ok for 20', not for 100'.
  10. Better pictures- even simple point-and-shoot cameras work well at 20', at 100' you need strobes and expensive equipment.

Next time: Advantages of deep water

Why You Should Never Fall In LOVE with a Scuba Diver
--by Jerry Kosakowski

I’m certainly not one to claim I know all about love but I’ll give you my advice on why not to choose a scuba diver. Do you like spending weekends by yourself while he is on a boat with scantily clad, sometimes naked women? Yeah, I didn’t think so. Can you accept that he’ll love diving more than you? Can you accept that he’ll talk about diving more than you? Yeah, that may be a deal breaker. Can you accept that he’ll be at the ocean every weekend that is a good weekend for diving and not with you? Yeah, those special occasions will not interfere with his diving. Can you appreciate that he’ll be flying off to exotic spots w/o cell coverage to enjoy the water? Those naked women pop into your mind again?

When you do accompany him to the ocean can you accept that he just stares at it and not you? Please don’t interrupt his staring with any conversation, it distracts him from his thoughts of being in the water and all the other times he was there enjoying himself. In winter can you accept that he’ll do a lot of reading? About the diving he is missing, again don’t interrupt this activity. Can you accept that he has a small group of friends, all of which love diving and some are good looking ladies (yeah, that naked thing just rang a bell again, didn’t it?)? Can you accept he has an uneven tan all the time? Can you accept the fact that when you do get to kiss him he probably has wet hair and smells of the ocean? Can you accept that he thinks bubble rings are fantastic? And describes them all to you? Can you accept he dislikes fancy dinners and prefers to have a sandwich on the beach, close to the ocean water? Can you accept that when a mermaid calls him he has to rush right over? Yes, he realizes it is your birthday, but he can’t help himself. Can you accept that he thinks you are weird for being afraid of sharks? Do you really think this is the relationship you want? I guess, only if you are a diver yourself. Then it’s a match made in the oceans.

A Fun Time Was Had by All at our Annual End of Season Event!

--by Rachel Davis

About 30 ADA members gathered at John U. Lloyd State Park in Dania Beach for the Annual ADA End-of-Season event on Saturday, Oct 10, 2015. Eleven divers enjoyed the beauty of the reef with flat calm seas. Kudos to new ADA member Sergio Figuera for bringing in the largest lobster!

Chef Roy Wasson cooked up a wonderful BBQ lunch, with grocery shopping done by Daryl Johnson. Jerry Kosakowski ran the raffle and many scuba related prizes were raffled off, including a wonderful haul of used dive gear donated by ADA members. It was a great opportunity to get together and socialize, and to commemorate a wonderful 2015 dive season. A very fun time was had by all.

Are Tanks Included?

A common and legitimate question we hear from our members. The answer is yes and no. Some dive shops/boat captains include tanks, others do not. Their reasons vary, but some find private tanks, for example steel 120s, do not fit in in the boat's custom-designed tank racks, others consider tanks a part of their professional service. When in doubt, just refer to our dive schedule page and those operators including tanks as part of their service will display "TANKS INCLUDED". If it is not noted, tanks are not included.

ADA TRIP CANCELLATION INSURANCE

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.

IMPORTANT MESSAGE FROM THE SAFETY OFFICERS’ COMMITTEE

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.

CANCELLATION AND REFUND POLICY FOR LOCAL DIVE TRIPS

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!)
