Dive Doctor?

How many of you have a doctor? OK… Pretty much most of you. Now, how many of you have a dive doctor? What is the difference? Why does this matter?

We mention this because we are always influenced by other forces and sometimes we limit our ability to dive because of various appliances we are wearing, physical problems we are experiencing or possibly, poor guidance from our “trusted” physicians because, they themselves, do not have all of the facts surrounding the effects of diving on the human body.

The motivator behind jumping into this topic is the fact that I have been wearing braces on my teeth for the past two years and in my consultation with my orthodontist, one of the first questions I asked was, “Will this impede my ability to dive?” Fortunately, his answer was no and I have been on several dive trips where I have not experienced any difficulty with my braces and diving. I thought, at first, that I may have a mouthful with my regulator and two rows of braces but it felt no different from what I remembered in not having my braces. In fact, I think it has helped me improve my “bite” by holding the regulator in my mouth more securely without chewing on the mouthpiece. So braces are okay!

Wear glasses? Two options are available for you here. If you are like me and hundreds of thousands of other divers, you can simply wear contact lenses while you dive. Some of the mask flooding and clearing exercises may be a little more uncomfortable because you are focused on keeping your contacts, but with practice you learn to not panic so you can get the job done. I recommend practicing many times first in shallow depths under controlled conditions before you venture into heavy currents and try mask clearing exercises. The alternate option, and growing in popularity, is to have prescription lenses built into your mask. Many companies offer this and our very own, Esther, had this done with great success. If you are unsure where to start, connect with your optometrist and your local dive shop who can guide you through this decision.

Sinus issue? I’ve had this, too! This is where the dive doctor came into play. Until I found a dive physician, I was receiving speculative answers regarding a bloody discharge from my nose as I surfaced. After consulting a dive physician he provided me with both a prescription inhaler to aid the sensitive capillaries in my nostrils and sinuses prior to my dive and then provided me with techniques and suggestions in slowing my ascent to allow my sinuses more time to adjust to the changes in atmospheric pressures. The benefit of the dive physician was cemented in my mind from that moment.

Ear issue? This is tricky. I have been fortunate not to suffer from ear blockages or equalization problems. How many of you have had problems here? What did you do? I don’t profess to have the answer, but pool sessions or controlled dives in shallow depths will allow you to adapt to the underwater environment slowly and build a physiological confidence in an unusual environment. A dive physician may help here but they can always recommend an ear, nose and throat specialist who can carefully diagnose your problem. However, if you are ever in doubt when it comes to your ears or sinus passages related to congestion, it is better to err on the side of caution than risk the possibility of losing your hearing or suffering permanent damage that will limit your ability to dive. “When in doubt, sit it out.”

Finally… Are you claustrophobic? This is difficult to remedy and happened to be Lana and Esther’s biggest fear when we started off in diving. What can help here? A very patient instructor who will not push you beyond your own limitations and a pool or dive site with a gentle slope to depth will certainly allow you to test your bodies’ response to full submersion. Once you are ready for open water, start off in water with great visibility. We remember our first open water dives at Mamutik Island off Kota Kinabalu. The sandy shore was gradual and there was never any fear of being too far away from the surface. For Esther, once we got away from the shore, she immediately began to feel the claustrophobia subside because suddenly the water was clear and she could see 360 degrees around her. If you suffer from claustrophobia or anxiety, just take it slow and let everyone in your group know that you might need a little extra time to adjust. With a great instructor and understanding friends, you will be enjoying many dives in no time at all.

As with anything medical, we want to heavily emphasize that we are not discounting any non-dive physician recommendation to not dive, nor are we providing you with a blanket waiver to get out there and dive without repercussion, but we recommend that you seek the counsel of a physician who is also an avid diver and may be able to offer you options that other physicians are not aware of.

Happy Diving!

Diving Into 2000 Years of History

Back in June, we jetted off to Europe for a quick vacation. As we sat at the airport in Brussels, Belgium, with standby tickets set up to go to Lisbon, Portugal, we looked at the dreary weather that was blanketing much of that country and with a swift decision, we changed our plans to a destination offering significantly more sun; Tel Aviv, Israel. Upon arrival in Tel Aviv, armed only with a Lonely Planet guide-book purchased the day before, we made a decision to rent a car. We embarked on an improvised ten-day, self-drive tour around much of the country to explore the fantastic sites in Jerusalem, Palestinian Territories, Galilee, Dead Sea and Golan Heights.

Now, the very mention of “diving in Israel” conjures up thoughts of the Red Sea with a palate of colors decorating the coral reefs and fish teeming about. However, what if we said we chose to explore the Mediterranean dive sites? While lesser known, these dive sites are peppered with archeological possibilities and excite the diver’s imagination and Shira highly recommended them to dive at Caesarea.
A little history… The historic port city of Caesarea in Israel was established by Herod the Great between 22 – 10 BC and named after its benefactor, Augustus Caesar, who bequeathed this region to Herod following the victory at the Battle of Actium in 31 BC. Herod’s determination to make this city great, resulted not only in the creation of a great Roman city with coliseums, baths, theaters & temples but also the construction of the largest artificial harbor in the open sea. Built to Vitruvius’ specifications, the structure of the two moles (breakwalls) was a stunning achievement in using ingenious Roman methods of poured concrete; a method that would be lost for centuries. A tsunami between the 1st and 2nd century would become a factor in the eventual destruction of the harbor which was eventually unusable by the 6th century. To gain a comprehensive understanding of Caesarea, read more on this interesting history on the dive center’s website about the design of Caesarea Maritima.

Caesarea is now a National Park and it must be noted that there is a nominal park entrance fee. The site is simply gorgeous with numerous archeological sites above land as you make your way to the modern coastal esplanade. West facing, the design of the park is impeccable! A great deal of attention has been paid to tastefully blending the design of modern restaurants, cafes, shops and museums with the surrounding archeological beauty. And the beaches? Spectacular and only made better without a cloud in the sky! Wow. We haven’t entered the water yet and this place is already incredible.

We made our way to the Old Caesarea Diving Centre at the end of the pier. With a little advance research, we discover it is the only dive operator located within the National Park and upon arrival, our first impression of the dive center was that of chaos and confusion. There were so many people everywhere! In fact, there were so many people in the dive shop that it was difficult to differentiate between divers and employees. We just needed to figure out the process for renting gear and getting started. Once the crowds seemed to dissipate, we found some counter real estate to talk to the coordinator and set up our time with a dive guide. The dive guide is necessary to explain the underwater archeological sites and review the dangers of the area. Getting outfitted with our gear seemed relatively easy as the rental coordinators were able to guess our sizes with a quick glance. Some of the equipment seemed a little old, but it was functional and would be good enough for the single dive.

Note: The dive center is very strict about only accepting certified divers. Without exception, your dive card, proof of dive insurance (i.e. DAN) and log book, with recent dives or a minimum number of dives, must be presented. All three are necessary to dive this unique historical site. We did not have our log book but the coordinators fortunately accepted the 30 recent dives as shown on our dive computers.

Before we dropped in the water, we were encouraged to discover the Mediterranean water temperature hugging the Israel coastline is much more temperate than previous experiences in the shared body of water around Italy’s southern island of Lampedusa. With temperatures hovering around 24˚C, Lana only required two wetsuits to keep her comfortable for her dive! Our dive master is a delightful Russian Israeli who really knows the area and explained the sites as shown on his map. He described the amount of swimming that would be involved above and below the surface as the archeological site is quite large and the underwater remains of the harbor are no different.

The dive had some interesting logistics. A dicey entry with moss-covered concrete steps into a one meter deep rocky bottom demanded each divers complete attention. Plan for a long swim to the site (10 minutes) and shallow depths can present buoyancy issues for novice divers (5 – 10m). The dive is pretty much at safety stop depth the entire dive and because of the shallow depth and concrete pylons in the water, it created a surge which can play havoc with persons who may experience underwater motion sickness. Halfway through the dive, Lana was feeling nausea because of a combination of the surge, her mask was too tight, and probably because she had two wetsuits on. It was a 70 minute dive of solid swimming and this left Lana knackered.

The dive visibility was pretty decent for the Mediterranean at about 15 meters despite a sandy bottom. Groups seem to be small at about 6-8 persons which is great and we were fortunate to be in a group with experienced divers from Israel and Italy. A safety buoy is necessary because there is a risk for fisherman lines off the pier and boat traffic nearby.

The true highlight of the dive is the opportunity to see the ancient harbor below, a collection of ancient (stone) and modern (iron) anchors below and the location of where the lighthouse would have stood. While the archeological dive site stole the show, marine life was still present. There was even a cool species of nudibranch which excited Tim. The dive guide was great at referencing the sites on the map under water, and with great coverage and discipline in 70 minutes, one dive proved to be sufficient as the group collectively decided a 2nd dive would not be necessary. Multiple dives are fine for those who want to explore more.

We enjoyed the rest of the afternoon like true divers; loitering around the Old Caesarea Dive Shop sharing stories, planting themselves at one of the cafes and then escaping the heat of the day by taking advantage of the museums and movie presentations which were exceptionally done. We followed up our below water adventure with an above ground exploration of the area as we explored the Roman and Byzantine ruins. Simply fantastic!

Caesarea may have 2000+ years of history but it certainly is well-established in the 21st century for modern-day conveniences. Many other sites may top your list for Israel, but Caesarea should definitely be considered. It will appeal to both diving enthusiasts and land explorers alike.

Sea Shepherd Visits Los Angeles Dive Center

What better way to spend a Tuesday night than with a great group of fellow divers at a local dive shop. Thanks to Eco Dive Center, we had the unique opportunity to spend time with the Sea Shepherd Organization and learn what their conservation efforts are really about. (To those of you in the Los Angeles area, Eco Dive Center holds a monthly diver get-together the first Tuesday of every month!)

We were very excited to learn more about Sea Shepherd and their adventures while filming of Whale Wars. To say that we learned a lot during their visit would be an understatement. They are a group of dedicated individuals who sacrifice having a “normal” life; leaving their families and friends behind, so they can help save helpless animals

As we settled in and began to listen to the seminar, we learned that the Sea Shepherd Organization has actually been operating since 1977, long before the inception of Whale Wars. We were further impressed by the fact that they have wildlife protection efforts not only in the Southern Ocean Whale Sanctuary but also in, Taiji, Japan (where the documentary The Cove was based on), Fiji, Cocos Islands and many other locations around the world.

We learned that over 70% of the world’s population of sharks have already been killed, leaving many species of sharks nearly on the endangered list. This absolutely shocked us. As we continued to listen, we became more and more grateful for the dedication of organizations like Sea Shepherd. Not only does Sea Shepherd defend whales, but they are also involved in the conservation of sharks, seals, dolphins, and blue fin tuna.

Leaving the Sea Shepherd presentation we were overcome with sadness. However, as we thought about the message that the Sea Shepherd team delivered, our sadness turned to hope. With the efforts of organizations like Sea Shepherd, people around the world will be educated and inspired to take action to help save our oceans. The future generations deserve to enjoy seeing a whale, or a shark when they are out enjoying our beautiful world.

We have hope that through the combined efforts of Sea Shepherd and the other organizations in the world along with the voice of the scuba diving community, we will be able to make a difference and be the voice for the animals that are senselessly killed every day.

Thank you Sea Shepherd for leading the charge to bring awareness to the challenges that our ocean is facing and standing up to the world to defend it!
