Close Encounters of the First Kind  - Marine Edition

--by Rachel Davis

Date: August 5, 2017
Location: Boynton Beach, Delray Ledges
Depth: 60 feet
Sighting: Measled CowrieMacrocypraea zebral

Even after 616 logged dives, there are times to this day when I encounter marine life that I've never seen before. And it happened again last Saturday. While diving Boynton Beach, I found a beautiful shell sitting in about 60 feet of water. It looked like a large cowrie with a slimy black resident snail inside.

According to the Humann/Deloach/Wik Reef Creature Identification book (see http://www.fishid.com/), this shell is found in reef recesses occasionally in Southeast Florida in depths from 6 to 35 feet,.

Date: August 5, 2017
Location: Boynton Beach, Delray Ledges
Depth: 60 feet
Sighting: Blade Fire Coral

On the same dive in Boynton Beach I also encountered a very interesting coral patch I had never seen before. I learned from my Reef Coral Identification book that Blade Fire Coral, Millepora Complanata, grows in atypical patterns that make visual identification difficult. That is why this coral looks nothing like any other fire coral I have ever seen.

Date: July 10, 2017
Location: Glover's Island Reef
Depth: 30 feet
Sighting: Juvenile Nassau GrouperEpinephelus Striatus

While diving in Grenada in July both the divemaster and I spotted a very unusual creature that neither of us had seen before. It was a tiny fish about one inch long that was barely moving on its own, and appeared to be carried along by the current. But it was clearly alive. I couldn't find this small fish in any book, but upon carefully analyzing the photograph, I concluded that it was a tiny juvenile Nassau Grouper.

Date: July 11, 2017
Location: Grenada, Veronica Wreck Night Dive
Depth: 50 feet
Sighting: Cryptic Teardrop CrabPelia Mutica

Also in Grenada on the Veronica Wreck Night Dive the divemaster pointed out the smallest crab I had ever seen in my life. It was only 3/4 in. long and it was beautiful flourescent orange with white. According to my Reef Creature Identification book was the Cryptic Teardrop Crab, a nocturnal animal which inhabits reefs and man-made structures.

Date: August 20, 2016
Location: Davis Ledge, Key Largo
Depth: 25 feet
Sighting: Red Serpent StarOphioderma Squamosissima/div>

On another ADA night dive last year over Davis Ledge, I encountered numerous beautiful bright red starfishes littered along the top of the ledge. Due to the lack of sunlight, our flashlights brought out the amazing red color of these animals unfiltered by the sea water. I was gazing upon the Red Serpent Star, a brittle star listed in the book as uncommon in South Florida. It was my first time seeing one and I have never seen one since.

So no matter how many dives you've done in your life, keep your eyes peeled for any unforeseen marine life you may encounter along the way. Then take the time to identify them and keep building on your body of knowledge. The variety and abundance of marine life ensures that we can never stop learning about our magnificent ocean environment.

The Importance of Safety Briefings

--by John Davis

Before every dive in ADA there is a safety briefing.  This article may seem a bit simplistic, because it seems obvious that we should have a safety briefing before each dive.  However, there are some very important reasons that this is a basic and routine part of every dive that we have in ADA.

We all need reminders.  We just do.  A lot of diving safely is due to hearing the same thing over and over again.  We need repetition, because when we find ourselves in a difficult or potentially dangerous situation (and it's going to happen sooner or later if you dive long enough), we will automatically respond in a safe and measured way thereby preventing a tragedy.  These ideas, whether they be about hand signals, buddy separation issues, and issues relating to weather and current need to so ingrained in our mind that we will recall them in a stressful situation.

Nobody knows everything about diving.  We are all in the process of learning new things about diving.  In fact, the more willing we are to admit that we don't know everything, the greater the chance that we will be able to hear that one idea that may just save our lives some day. Every once in a while, I will pick up on a new idea on how to deal with current, or how to stay safe during a thunder storm.  Staying open to new ideas makes me safer.

Every dive situation is different.  We don't dive with the same considerations when we are diving on a 15 to 20 foot reef in Key Largo as we would when we dive on a sheer wall in the Cayman Islands.  Some basic diving elements are always in play, but there are many different challenges that should be evaluated in each situation.  It would be dangerous to jump into the ocean having no general idea about the current, depth, or style of diving (drift or coming back to anchored boat).  To not know the situation would be extremely foolish.  No diver who cares about his/her safety would dive without a through briefing about the landscape of the dive site.  So, we talk about current, depth, what type of gauges (air integrated, etc.), nitrox/air issues, type of dive (drift or anchored boat), and whether to do safety stops, controlled emergency ascents or buddy breathing (depending on depth).  We must know these things, so that if that emergency occurs we will know exactly how to react in a safe way.

Safety briefings are such an important element of every single dive in ADA.  ADA prides itself in it's incredible safety record.  This record in large part is due to the importance put on a through safety briefing every single dive.  Diving is fun.  We must however always put safety first.  If it's not safe it will not be fun.  Thanks to ADA's safety briefings we will continue to have many more years of enjoyable diving!

Is Treating DCS Necessary?

--by Mo Smith

Years ago I remember reading an article discussing if there was a need to treat Decompression Sickness (DCS) or with time would the body self heal. I can’t recall if the article was published by Divers Alert Network (DAN) or by one of the other dive magazines, which I frequently read. Recently this discussion once again surfaced with a group of long time dive buddies.

Recompression Chamber: LeisurePro.com

The article explained that the bubbles with time will eventually dissipate but the untreated symptoms of DCS could last a lifetime. The problem is that even though the bubbles disappear with time, the damage created can become permanent and can generate long-term effect.  DCS if not treated can damage the affected area by impeding blood flow or impinging nerves.  Long term DCS can cause biochemical changes (ie: the way the body fights diseases or how it responds to drugs). Even with DCS therapy residual symptoms is common.  The sooner the DCS treatment is attained the better chance the diver has for a comprehensive recovery.

A divers body does self heal with what is consider DCS stress.  It is theorized that a diver is exposed to DCS stress on every dive.  The exposure is so minor that the body will self-resolve the exposure. An example of DCS stress is the fatigue feeling that can occur after a single or multi-days of diving.

A simple formula to diminish dive injuries is to keep training and learning, Scuba Diving Physics often change. Stay within your training and safety dive limits as well as keep current. Reduce the possibility of DCS injuries by following the rules (Plan your Dive and Dive your Plan).

The ADA is very proud of their record of not ever having a dive injury within an ADA sanctioned dive.  They’ve accomplished this by understanding safe diving.

Knowledge is power.

Surprising Shark Facts
--by Lon Von Lintel
  1. Some sharks can walk on the bottom.  In 2012, a new species was seen in Indonesia walking, seeming to avoid swimming.
  2. Flat sharks, some call them, but they are better known as rays. They are closely related to sharks.
  3. The Great White shark is called white pointers in Australia, and blue pointers in South Africa.
  4. The Greenland shark is the oldest living invertebrate and lives to be 400 years old.
  5. Some sharks, like the thresher shark, give live births.
  6. The blue shark is the most caught for their fins, some 20 million yearly.
  7. Some sharks return to their birth place to reproduce, like the lemon shark in the Bahamas.
  8. The whale shark feeds only on small fish, invertebrates and plankton.

Is Your Sunscreen Poisoning
the Ocean?

-- from the New York Times (submitted by Ellen Siegel)

Up to 14,000 tons of sunscreen enter the world’s reefs annually, according to a 2015 paper published in the journal Archives of Environmental Contamination and Toxicology. Most of it — including products by Aveeno, Banana Boat, Coppertone, Hawaiian Tropic and Neutrogena — contains a chemical called oxybenzone to deflect UV rays.

Even in minute doses, the researchers found, oxybenzone rapidly bleaches coral and slows new growth: A single drop in 4.3 million gallons of water — about six and a half Olympic-size swimming pools — is enough to be deadly.

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!)
