Scuba Diving in Seychelles and Coral Bleaching


Most visitors to the islands of Seychelles never get to experience the wonders that await you when you go scuba diving or snorkeling there. They stay on the beach and marvel at the incredible sands and do not think much about whence it came.

Seychelles is a group of 155 tropical islands scattered around almost one million square miles of sea in the Western Indian Ocean. It is well known for its gorgeous white coral-sand beaches but its underwater beauty and abundance of fish is still relatively undiscovered and unknown.

Scuba diving in Seychelles is as good as ever. People are talking about "coral bleaching" and coral dying in Seychelles like it were a new phenomenon that somehow should be stopped and reversed if possible. That's because people are not being given all the facts especially by those who should know better. Coral bleaching is only nature's work in progress. And those that have been diving around these islands for 10 years or more know differently. And it's not all bad.

But some scientists may have their own agenda. So you end up not knowing all the facts. Put in a nutshell, the death of corals has been happening for thousands of years in Seychelles. As Charles Darwin put it best, it's all about evolution, survival and adaptation. Do corals die? Absolutely, but should we be concerned? Definitely not! Not in Seychelles anyway.

In Seychelles the resultant dead corals provide more pasture for herbivores like surgeon fish and parrot fish, which saw an increase in numbers after the so-called coral-bleaching event of 1998. Those who study it seem to recognise that it comes in a cycle, every 10 to 12 years linked to the El Nino effect. So it's a natural phenomenon.

At that time the weaker ones die. The law of natural selection kicks in. The strong survive and propagate and the world carries on turning. So it's not the end of the world. And the reef is as good as new after a relatively short period of time of 2 to 3 years. And during that time some fish species increase in numbers due to increased forage provided by new algae growth. And it will come again...

When I go scuba diving in Seychelles and notice some coral bleaching happening again in 2010 it reminds me of the nature of life - growth and decay, life and death, adaptation and survival, and evolution through natural selection. But more importantly it reminds me that this same process has been happening for thousands of years. So why all this fuss now?

It also reminds me that this is the reason that we have such beautiful white beaches in the Seychelles. It's all part of the same process. Some of the bleached coral will eventually add to the sand store on the beach, a thousand years from now. So it's all good.

Would I campaign to try stopping the cyclic coral event? Absolutely not! Why would I want to fight nature? How would you fight it anyway? It sounds like a recipe for failure. When I see this I actually enjoy it. It's like the winter snow. And I know that when the "sub-marine spring" comes, just as certain as the next sunrise it will be even better and more beautiful.

Look at it with a fresh pair of eyes. Let nature do its work and get pleasure from it next time you go scuba diving in Seychelles. And when I get back to the beach I know that nature has been good to us. How can anyone fault it when you see the amazing white coral sands of the Seychelles?








And you know that the bleached coral was only a tiny link in the chain of events that led to these amazing Seychelles beaches.

Shadow Divers: The True Adventure of Two Americans Who Risked Everything to Solve One of the Last Mysteries of World War II

Shadow Divers: The True Adventure of Two Americans Who Risked Everything to Solve One of the Last Mysteries of World War IIIn the tradition of Jon Krakauera€?s Into Thin Air and Sebastian Jungera€?s The Perfect Storm comes a true tale of riveting adventure in which two weekend scuba divers risk everything to solve a great historical mysterya€?and make history themselves.

For John Chatterton and Richie Kohler, deep wreck diving was more than a sport. Testing themselves against treacherous currents, braving depths that induced hallucinatory effects, navigating through wreckage as perilous as a minefield, they pushed themselves to their limits and beyond, brushing against death more than once in the rusting hulks of sunken ships.
But in the fall of 1991, not even these courageous divers were prepared for what they found 230 feet below the surface, in the frigid Atlantic waters sixty miles off the coast of New Jersey: a World War II German U-boat, its ruined interior a macabre wasteland of twisted metal, tangled wires, and human bonesa€?all buried under decades of accumulated sediment.
No identifying marks were visible on the submarine or the few artifacts brought to the surface. No historian, expert, or government had a clue as to which U-boat the men had found. In fact, the official records all agreed that there simply could not be a sunken U-boat and crew at that location.

Over the next six years, an elite team of divers embarked on a quest to solve the mystery. Some of them would not live to see its end. Chatterton and Kohler, at first bitter rivals, would be drawn into a friendship that deepened to an almost mystical sense of brotherhood with each other and with the drowned U-boat sailorsa€?former enemies of their country. As the mena€?s marriages frayed under the pressure of a shared obsession, their dives grew more daring, and each realized that he was hunting more than the identities of a lost U-boat and its nameless crew.

Author Robert Kursona€?s account of this quest is at once thrilling and emotionally complex, and it is written with a vivid sense of what divers actually experience when they meet the dangers of the oceana€?s underworld. The story of Shadow Divers often seems too amazing to be true, but it all happened, two hundred thirty feet down, in the deep blue sea.

Scuba Diving in Belize - What Does the Fascinating Adventure Package?


Located in the western Caribbean ocean and south of the Yucatan peninsula, you will find the small Central American country of Belize. Home to the second largest barrier reef in the world, scuba diving in Belize offers an adventure to see the hundreds of different types of coral, sponges and other marine life from the dozens coral atolls or cayes as they are called in Belize.

Whether you are a beginner or experienced diver, you will find everything you need available at the many dive shops or resorts to make your diving adventure truly one for the log book.

If you have never been scuba diving before you can sign up for classes at one of the many dive shops or dive resorts. The classes range from very basic scuba breathing in shallow water, open water certification or advanced certifications. All scuba diving in Belize is done under the watchful eye of the Belize regulated dive masters.

Check out dives and certifications are available for those who have completed their classroom work and basic scuba instruction, but have not completed the final exam. It is a good idea to call ahead to the dive shop to make sure you bring all of the needed paperwork from your stateside instructor.

Several dive operators offer Live-Aboard diving boats that will take you to many of the popular diving locations in the lap of luxury. The all inclusive rates include room, meals and air all just a few feet away from your room. Make your reservations well in advance as these boats are quite popular.

Located on the southern end of Ambergris Caye and a short boat ride from San Pedro are the popular diving locations known as the Hol-Chan Marine Reserve and Shark-Ray Alley. This protected area is divided into 4 zones, each with its own unique habitat and bio-diversity. Coral reefs, mangroves and sea grass beds make up the different sections of the reserve. Hol-Chan is also one of the best night diving sites.

Expect some company when you arrive at Shark Ray Alley. For years the local fishermen have been cleaning their catches here so the sharks and rays will appear near your boat expecting a free lunch.

Another popular diving spot located on Lighthouse Reef, a day trip east of Turneffe Reef is the famous Great Blue Hole. Explored and filmed by Jacques Cousteau in the early 1970's, it is more than 400 feet deep and 1000 feet across. Blue Hole offers the experienced diver a chance to go deep, while exploring the corals and stalactites that were formed when the sea levels were much lower.

The scuba diving in Belize is different from other areas in the Caribbean as the water temperature only varies between the mid 70s to the mid 80s year-round. Water visibility varies upon location but you can expect to have 50 foot or better viewing with 100 foot visibility not uncommon in some areas. Water clarity will be less in the rainy season during the summer months.

Swim with the Whale Sharks, chase the rays, feed the groupers or relax in the shallow mangrove cayes beside the manatees. Going scuba diving in Belize has something to offer all divers regardless of experience. Make your reservations early and be prepared for the diving experience of a lifetime.
