Diving in Dominica

--by Carol Cox

Many people mistake the island of Dominica for the Dominican Republic. Other than both are in the Caribbean, the two couldn't be further apart. Dominica is in the southern Caribbean, north of St. Lucia and south of St. Kitts. There are two areas of great diving, Cabrits in the north end, and the Scotts Head Pinnacle area of the south end. There are several good places to stay and dive in Dominica, my preference being the Castle Comfort Lodge near Roseau. They are right on the water, just outside of town and have comfortable, clean rooms, a restaurant and bar featuring delicious Caribbean cuisine and best of all, right on the premises is Dive Dominica, a complete dive operation with a fleet of roomy, comfortable dive boats. One of the most famous dive sites in Dominica, just south of Roseau, is Champagne, where you can 'effervesce' in the bubbles rising from volcanic vents under the sea floor.

There are dozens of dive sites near the south end of Dominica from easy to difficult, depending on the current. Dangleben's Pinnacles are easy to moderate, while the dives on the other side of Scott's Head Pinnacle can be demanding. Diving is not all there is to do in Dominica. After a morning of clear water diving, an leisurely hike to one of Dominica's many waterfalls and pools easily fills the afternoon. Hikes to Titou Gorge (where you can swim or float through the caverns), Emerald Pool, and Trafalgar Falls all have non-taxing access trails. Try a more demanding hike on an non-diving day. Boiling Lake is a 6 hour round-trip to a volcano-heated lake of boiling water. A guide is recommended on this hike.

If hiking is not your forte, Dive Dominica has fabulous shore diving right off their dock. Grab a tank and jump in. Octopus, sea horses, corals, sponges, schools of fish, and anemones, along with anchors and miscellaneous boat parts are found in less than 25 feet of water. There is a long cable that extends underwater from the dock that you can use for finding your way back to shore.

So, if you are into diving and hiking, the mountainous island of Dominica is worth it, even including the narrow canyon landing on an airstrip that ends at the water's edge! Flights from San Juan, Puerto Rico are readily available as well as from other Caribbean islands. Many cruise ships also have one day stops in Dominica and have shore excursions to Champagne or other nearby dive sites. Caribbean diving at its best!

Photography Part 4 - Lighting

--By Dan Baeza

Summary - Desirable Features in a Strobe:

  • Large Guide Number
  • Master/Slave Capability
  • Fast Cycle Time
  • Variable Beam Angle
  • TTL Compatibility
  • Small Size and Low Weight
  • Daylight Color Temperature
An Example of Backscatter
Note the white particles on the blue background in the upper left.

In photography, the proper lighting is vital to make your photo “pop”. Underwater photography is an even more critical environment with regards to lighting. Because water absorbs the color spectrum in graduated steps as you descend, the flash or strobe is necessary to restore color to your subject. The terms “flash” and “strobe” are used synonymously, although “flash” typically implies a light source integral to the camera, while a strobe is a separate outboard device.

The strobe, when properly positioned, also reduces backscatter that tends to show up on dark backgrounds or subjects. Backscatter is caused by particulate in the water that reflects back light into your lens and looks like “snow” on your photo.

What features are desirable in a strobe? Some of the desirable features are a large guide number, capability of being used as a master or a slave, fast cycle time, variable beam angle, TTL compatibility, size and weight, and color temperature. Let’s examine each of these in detail.

Guide Number: Light output in strobes can be measured in several ways including lux, lumens, and watt-seconds. The most popular measurement and one that can be used across all strobes is the guide number. The guide number, abbreviated as GN, is defined as the light needed to produce a correctly exposed photograph at a subject-to-strobe distance of one meter multiplied by the recommended f-stop (see Photography Part 2 – The Mechanics in the March Newsletter) at ISO 100 with the strobe operating at full power. What’s all that mean? Say for example, the GN of your strobe is 20. To get the aperture setting, divide the GN by the distance. If your subject is 3 meters away (about 10 feet), then you need an f-stop of 20/3 or 6.67 (round down to the next available f-stop, f-5.6). A camera with a built-in flash may have a GN 20 or 30, while a strobe’s GN may be 250 or more. In the case of strobes, bigger is always better, albeit at a price. A strobe can cost as little as $100, all the way to $3000 or more, depending on features.

Master/Slave: Strobes come in two flavors, master and slave. A master strobe is electrically attached to the camera’s shutter mechanism and fires when the shutter is tripped. A slave strobe uses flash detection circuitry to trigger the slave when it “sees” the master flash. The ability to use your strobe in either mode allows it to be used as a primary or, if two strobes are needed, as secondary illumination.

Fast Cycle Time: A strobe only delivers its maximum output if it is fully charged. The charge rate depends on the condition of the batteries and the speed of the charging circuitry. Look for a cycle time of under 2 seconds with a fresh (fully charged) set of batteries. As the batteries discharge, the cycle time will increase, meaning you might not be able to take that second shot of the octopus sliding away. Related to cycle time and battery life is the number of shots per full charge. Expect at least 100 shots per fully charged battery pack. Once again, more is better.

Variable Beam Angle: The ideal strobe angle of coverage is dependent on the subject matter. A wide-angle shot will require an angle of coverage of at least 120 degrees. A wider angle requires more power, so you want to be able to narrow the beam angle when a wide shot is not needed to conserve battery life.

TTL Compatibility: If your camera is a TTL (Through-The-Lens) that can intelligently synchronize with your strobe, then TTL Compatibility is a must. Without TTL capability, you would have to shoot in manual mode.

Size and Weight: You’re going to be carrying around a camera, housing, and spare batteries, so the last thing you need is a bulky and heavy strobe. When traveling to international destinations, be mindful of carry-on and checked luggage restrictions.

Color Temperature: Look for a strobe that delivers daylight lighting. That is, color temperatures of 4500K to 5700K. The warmer 4500K (it’s an inverse relationship) delivers better reds in wide angle shots.

A strobe when used properly will make the difference between a bland, average shot, and a vivid, spectacular shot. Without auxiliary lighting, the underwater environment will steal all the color out of your photos. A strobe restores the lost color and detail and makes your photos come alive. If you’re serious about underwater photography, then a strobe is a must!

The History Of Scuba Diving - Part One

--by Roy D. Wasson

Diving BellThe science and technology of scuba diving has evolved rapidly during the time that many of our ADA members have been diving, making some of us older members feel that we have been directly involved in seeing most of scuba diving's history being made. However, modern scuba diving is the result of thousands of years of trial and error, innovation, ideas and daring experiments. This first installment in a two-part series examines the early roots of humans’ efforts to explore the ocean bottoms by breathing while under water.

Before turning back the hands of time, I will remind our readers that the term “scuba” stands for “Self Contained Underwater Breathing Apparatus”. The coining of that acronym for our sport/hobby/profession marked the turning point from diving while tethered to the surface by lines and hoses to being able to move about independently while below the surface. The first practical self-contained system was not invented until 1939 by Christian Lambertsen, whose system was originally called the “Lambertsen Amphibious Respirator Unit.” It was not until a paper Lambertsen wrote in 1952 for the National Academy of Sciences was the phrase used that led to the abbreviation “scuba” for his invention. The next installment of this series will start with Albertsen’s invention, so the present article is limited to the diving apparatus that was not “self-contained.”

For at least five thousand years before the invention of the demand regulator, people have been finding ways to operate below the surface with more than the air they could hold in their lungs with a single breath. Drawn by the desire to harvest sponges, oysters, and other bottom-dwellers, ancient humans started trying to maximize their time under water by breathing through hollow reeds. Alexander the Great, the king of Macedonia,

used military divers breathing through such reeds at shallow depths to install submerged barriers to impede invading ships. Herodotus describes how two Greek divers, probably breathing through short reeds, cut the Persian fleet adrift during the Peloponnesian War in 415 BC. There are many drawings of divers from the Roman Empire wearing leather helmets with long tubes supposedly supplying air from the surface, but such contraptions could not have worked more than a few feet below the surface due to pressure differentials.

The Greek philosopher Aristotle in the fourth century BC wrote about early efforts to spend more time under water with primitive diving bells: “They enable the divers to respire equally well by letting down a cauldron, for this does not fill with water, but retains the air, for it is forced down into the water.” Sponge divers would work near such inverted containers, returning periodically to take a breath or two.

Breathing is not the only challenge under water. Divers also have to be able to see what they are doing. Around 1300 AD divers from Persia were documented as having invented a rudimentary form of goggles, using thin slices of shells from tortoises that were polished until they could be seen through.

During the 1500s, heavily-weighted wooden barrels with open bottoms were lowered onto dive sites to allow divers to come into the air pocket and get a breath while working at depth.

In 1715, an Englishman named John Lethbridge invented a one-man diving barrel with a glass porthole and arm holes with watertight leather sleeves that allowed a single diver to perform work below the surface. Also in 1715, an English inventor named Becker invented the first real diving suit, made of leather with a large, spherical metal helmet that had a window. Becker’s suit had three hoses leading to the surface: two for fresh air being forced downward by men operating bellows and one for exhaled hair.

Everyone has heard of Sir Edmond Halley, the astronomer whose name the famous comet shares. What few people know about Halley, however, is that he spent extended periods of time deep underwater. In volume 29 of the Philosophical Transactions, dated 1714-1716, Halley published the results of his experimentation in new ways to work comfortably underwater, titled suggestively: “The art of living under water”. Halley’s work, in which he improved existing models of diving bells, turned out to be influential for years after its publication, and his techniques were implemented by many undersea laborers. One of those techniques was to replenish the air in the diving bell by repeatedly lowering barrels of air. He also invented a system using a watertight hood and hose that allowed workers to leave the bell and walk around on the bottom. Halley’s improved diving bell could send several men (there is no reference to women divers back in those days) to the bottom for salvage work, where they could spend up to ninety minutes at depths of up to sixty feet.

It was not until the late 1700s that divers could spend significant time under the surface, following the invention by British Engineer John Smeaton of an efficient air pump that could easily replenish the air in the diving bell. Smeaton’s bell and pumping system became the “state of the art” in diving bells for the next century and a half. His bell was made from cast iron; it had the first efficient hand-operated pump to sustain the air supply via a hose; an air reservoir system and non-return valves to keep air from being sucked back up the hoses when the pump stopped.

In the 1820s the first traditional “hard hat” metal diving helmet was invented by John Deane, using modified firefighting equipment. Deane’s system was improved in the 1830s by Augustus Siebe of Germany. The suit connected to the helmet was made of rubberized twill which protected the diver from the elements at depth. That system was so successful that the English Royal Navy starting in 1839 used it in operations and founded the first ever diving school.

In 1864 an improved diving suit was invented by Frenchmen Benoit Rouquayrot and Auguste Denayrouze. Although it was still not completely “self-contained” because it used a hose from the surface pumping air into a closed helmet, the suit was fitted with a reservoir that would allow the diver to detach briefly from the hose for a period of a few minutes. During the late 1800s diving pioneers experimented with using pure oxygen, learned the hazards of decompression sickness, and expanded the uses of diving for many military and commercial purposes. Submarines became a permanent feature of Navy fleets of major world powers, and humanity’s connection with the undersea world was firmly established.

The author acknowledges resources used in this article including Trevor Howard’s book entitled Stars Beneath the Sea, The Pioneers of Diving (Carroll & Graf Publishers 1999), and the website entitled Underwater Exploration Timeline, which can be found at http://seagrant.wisc.edu/madisonjason11/timeline/index_1700.html In the next installment of this series, we learn how divers cut their “umbilical cord” tethering them to the surface and how scuba was born and evolved into the present time. Dive safe!

What in Criminy is a Crinoid?

--by Rachel Davis

On my first dive ever off the beach in Cozumel, as we approached 20 feet I saw a furry plantlike thing growing up off the ocean floor. I reached out to stroke it. The divemaster scolded me with a stern look and a shaking finger. My second lesson in diving after “always breathe” was “don’t touch anything!” Unbeknownst to me, I had a close encounter with a crinoid.

criniod

Not a plant at all, crinoids are marine animals that make up the class Crinoidea of the echinoderm family. Crinoidea comes from the Greek word meaning having the form of a lily, which is why I thought it was a plant. Divers see them plentifully in shallow reefs, but they can live at depths as great as 20,000 feet! Though some such as the feather stars are free swimming, most are attached to the sea bottom by a stalk.

Crinoids feed by filtering small particles of food from the sea water with their feather like arms. These are covered with sticky mucus that traps any food that floats past. Once they have caught a particle of food, the cilia are able to propel the food towards the small mouth which is nestled between their arms. They reproduce asexually by releasing both sperm and eggs into the surrounding sea water. The fertilized eggs hatch to release a free-swimming larva. The larva swims free for only for a few days before settling and attaching itself to the bottom. Within 10 to 16 months the crinoid will be able to reproduce.

Next time you go diving look out for these beautiful feathery creatures and you will have yet another marine life specimen to identify and admire.

Coral Bleaching

--by Jerry Kosakowski

This is the perfect picture of coral bleaching. It is destructive and harmful to our reefs. It makes me wonder if the reefs will even survive. Here are some important facts about it. The main cause is exploitation. That means manmade and I’m not talking global warming, although that can have an effect. It is: overfishing, increased sedimentation and nutrient overloading. The good part is that we as scuba divers have a minimal effect on it.

It can also be caused by extreme temperature changes, both cold and hot. Sometimes the coral may recover depending on how bad the situation is. But overall more and more coral is being killed off by this process. This does not bode well for our reefs our scuba diving adventures.

In 2005 there was a loss of 50% of coral in the Caribbean due to warming. In 2010 there was a massive loss in the Keys due to cold water.

Here is an excellent diagram from National Ocean Service on the topic:

 

The bottom line is that it is not visual or healthy for the oceans. If the coral dies the fish and everything around it goes too. Sadly most of the fish species live or procreate around coral.

But there is hope. There are many experiments being done to find solutions to this situation. One is the Coral Reef Foundation. We will be having a dive with them this June and learning and helping on this matter. I personally have done this several times and have found it to be very rewarding and informative. Plus the Nedimyerr family (who operates it) are just great people. It’s a family operation and you feel like part of them. If you have tried it, you know, if you haven’t give it a try and help the oceans.

ADA Dive-Cruise Update

--by Daryl Johnson
Emerald Princess Exterior

Our first annual ADA Dive-Cruise aboard the beautiful Emerald Princess is filling up. So far we have five cabins booked for this November 14, 7 day trip to Roatan, Grand Cayman, and Cozumel, and I have heard a lot of enthusiastic chatter among ADA members!!! Just a little reminder that cruises prices vary throughout the year as they are marketed very aggressively, so the sale price on balcony cabins that many of us booked earlier is not currently available. However, I expect that there will be various offers with combinations of on board credits (OBC) and price changes between now and this fall.

Emerald PrincessKeep in mind that our Princess Cruise Planner, Karen Bradder (1-800-901-1172 ext. 41643 ) ,can only offer what Princess has to offer when you call. However, she has promised that she will re-fare the entire group (you must be part of the ADA Group Booking) to any lower fare that Princess advertises if I simply call her when I see a better fare. And don’t forget, depending on the number of cabins booked and the average price, everyone in the ADA group will get an OBC for the group booking.

See you on board!!

What Should I Take On An International Dive Trip?


--by Daryl Johnson

There are many options when traveling abroad these days, all the way from taking every conceivable item you own, to taking a credit card with a high limit and buying what you need when you get there! When it comes to a dive trip you need to make additional preparations, as most good dive locations can be a bit remote. First and foremost, you must take a passport and your C-card. You can get “electronic” versions of your C-card from some agencies and as a backup, you can store pictures on your smartphone. Here is a short list of other items you should consider:

  1. Standard Dive gear: mask, fins, snorkel, BC, regulator, wet suit, gloves, and booties.  Be sure and check if some of this gear is included in your dive package, as you may wish to use some rental gear to save weight for air travel. At a minimum, I suggest you take your own regulator and mask in your carry-on luggage.
  2. Extra dive gear: dive lights and spare batteries for dive computers and lights, safety sausage, maintenance kit, dive bag. These days you need to take all lithium-ion batteries out of any gear that you put in checked baggage due to the fire hazard they can present, not to mention the weight savings. However, it is difficult for the scanners to tell whether your batteries are lithium-ion, nickel-cadmium (nicad), or alkaline, so remove them all to avoid the TSA from tearing apart your luggage.
  3. Dry bag
  4. Cameras, chargers, spare batteries, and extra SD cards
  5. Swimsuits
  6. T-shirts, shorts, sandals, and a windbreaker. This is one place where the high limit credit card can come in handy to add locally purchased “resort wear” to your wardrobe!
  7. Sunscreen, medications, contact lens paraphernalia (if you wear them).
  8. Inform your credit card company that you will be traveling out of the country. Also, make sure that you have more than one credit card in case you have any unexpected problems. Credit cards with security chips in them are frequently required outside the USA, so you should try and have one of these too.

It’s a good idea to take paper copies of your important documents such as passports, C-card and credit cards and store them separately from the originals. And it always helps to make sure that all your gear works before you leave, as it is very expensive to get equipment repaired at a resort.

That’s about it. Get ready for that great dive trip knowing that you will be ready with all that you need!!

Diving Attitude Part 1 - The Pitch Axis

--by Lon Von Lintel

A diver's physical attitude u/w refers to the pitch axis of the body, (the head-to-feet axis) and its position relative to the surface.  For maximum locomotion efficiency, energy conservation, minimal air consumption, and comfort, a diver's attitude, while swimming, should be parallel to the surface, 0 degrees.  Lets review several of the reasons that can cause a misalignment.  Being over weighted, (lead weight, not body fat) requires a diver to swim at a head-high, feet-low attitude, an angle of 15-45 degrees, to compensate and maintain a given depth.  The obvious correction is to adjust the amount of weight.  (see previous articles on buoyancy control)   Less obvious, but nearly equal in importance, is the placement of the weight along the axis.  If a properly weighted diver still experiences the necessity to swim on an angle, and his feet sink when he stops, weight placement is the culprit.  The solution is to move the center of gravity toward the diver's head. For divers who use a weight belt, slide the belt from the lower hips toward the mid-section of the torso. This is difficult while above water, but under water is easier. If this is not physically possible, (divers less than 6' tall will find this difficult) remove 1-2 lbs from the belt and clip to upper BCD.  For divers using the integrated weight system, remove 1-2 lbs. from the BCD pocket and clip an equal amount on the upper BCD.

Finally, air in the BCD will shift the center of gravity toward the diver's feet and cause the diver to swim on an angle, even though his buoyancy is neutral.  In previous articles on buoyancy, it was assumed that the diver makes weight adjustments to achieve neutral buoyancy with no air in the BCD.  So this diver should go back and adjust weights with no air in BCD.

A footnote: Peter Taylor and I were diving the Tenneco Towers several years ago.  At about 80 feet we noticed a diver (not an ADA diver) in a vertical position, about 50 feet from the tower.  She was kicking frantically to maintain depth control.  Her breathing rate was off the charts.  We instantly recognized this as a classical symptom of gross over-weight.  We knew instinctively she would soon panic, exhaust her air, and plunge rapidly to the 120' bottom.

Her "buddies" were oblivious to her plight. With no one else to help, we raced out, grabbed her arms, and pulled her over to the tower.  Gripping a cross beam of the tower, she regained a normal breathing cycle and calmed herself.  Then her buddies arrived and escorted her to the surface.

Points to ponder: Do you want that kind of "buddy"?  Did she have the necessary experience/skill to make that dive?  Why was she grossly over-weighted?  Wonder why ADA screens members for advanced dives?

Diving Tips & Tricks: Clearing Ears
--by Carol Cox

One of the most common reasons for a diver to abort a dive, or give up diving altogether, is the inability to clear ear passages when descending and, in some cases, ascending. The Valsalva maneuver is the most common method – pinching your nose shut while gently exhaling but this doesn't always work for everyone. If you experience ear pain, stop and ascend until the pain ceases then continue a slow descent as long as the pain does not return. If you cannot descend, try some of these tricks:

  • 'Pop': when you swallow, you should hear a 'pop' in both ears, letting you know both eustachian tubes are open.
  • Chew gum before the dive because it makes you swallow often. Gently equalize your ears every few minutes.
  • Pre-pressurize at the surface but remember to do it gently. Descend feet first – it is more difficult to equalize when your head is down.
  • Look up. Extending your neck tends to open your eustachian tubes. Also, bend your head from side to side to help open tubes.
  • Use a descent line. Stop descending if you feel pressure and wait or ascend a few feet.
  • Avoid milk before diving – milk tends to increase your mucus production.
  • Use a good fitting mask. Water up your nose can irritate mucus membranes.
  • Push your jaw forward and tense your throat muscles until you hear your ears 'pop'
  • Pretend that you are going to yawn – push the jaw forward and down to pull the eustachian tubes open. Some divers are able to control those muscles and hold their tubes open for continuous equalization.

Although not recommended but practiced by many divers, take a Sudafed prior to diving. The ramifications of this method are that the medicine might wear off before the end of your dive or make you feel nervous but many divers swear by it. The natural methods of equalization should be practiced before using a prophylactic. Have a safe and comfortable dive!

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!)
