Diving Trip to Sipadan

SCUBA Diving News Feed (RSS)

Manchester - Singapore - Sipadan

With a business trip to Singapore looming and no holiday

organised for the Red Sea this winter, I looked for an
extension to the Singapore trip to get in some good diving.



I first tried some UK dive tour operators to see if a
stop-over in Singapore could be organised but the flights
were not available. Then it was onto the web for a local
operator to book a tour out of Singapore. I found several
but selected Waikiki Divers because they seemed to have
flexible tour lengths and times. A quick email followed
by a phone call put me in touch with Stella Lee from
Waikiki who was able to create a six day, five night trip
to Sipadan on the day required, and returning in time for
the flight back to Manchester.

From Singapore it was a 9:30 am taxi to the Senai airport
across the border in Malaysia, a flight to Kotu Kinabalu,
followed by another to Tawau, and then a one hour minibus
ride to get within one last leg of the destination. A one
night stay at the very spacious and quite luxurious
Seaquest Hotel in Semporna was the break in the journey.

The following morning at 8:30 am we were met by the
mini-bus which transferred us the short distance to the
jetty where Palau Sipadan resort tours have their shore
base. A 1 hour speedboat ride was the final staqe to get
to Kapali where the accomodation is in wooden chalets
connected by wooden walkways built over a submerged reef,
with a small very white beach uncovered at low tide. No
one has been able to stay on Sipadan itself since 1/1/2005,
apart from some soldiers whose job is to prevent divers who
land there for their surface interval, from wandering off
down the beach or into the inerior of the island.

Our group comprised one from England, an American, a
Canadian, a Turkish couple and a Japanese, so plenty of
opportunity for swapping notes on world diving.

The Sipadan Diving

The check out dive followed later in the morning and
was a dive from the jetty at the dive centre. Basically
a sandy bottom with coral blocks and quite a variety of
small fish. In the afternoon a short boat ride to
sweet-lips table led to a similar dive but with somewhat
bigger fish (sting rays, large jacks) giant mantis
shrimps and a very large turtle. Most evenings the dive
centre organised a dusk dive for those with the energy
left. Some considerable time was spent trying to get
photgraphs of a shy mandarin fish.

Copyright Fatimah Duffy-Renfro, http://www.scuba-azusa.comThe next day we took the boat to Sipadan (about half an hour away with 300-400 horsepower behind us). In the morning we dived at the coral garden area, and after a break went to the South Point. Here the life was what you might expect from one of the top dive sites in the world. I counted 11 white tip reef sharks resting on the bottom, was passed by a six foot tiger shark going the other way, one Napolean wrasse, too many turtles to count
and an octopus in the shallows at the end of the dive.

For variety we also went to Mabul Island where we dived
in the junk underneath the SeaVentures rig. Here were
plenty of exotic small creatures (nudibranchs, frog fish
etc) but too much man-made rubbish for my liking.

Further dives at Sipadan saw similar numbers of macro
creatures, including a large shoal of barracuda forming
the traditional swirling cylinder, and again an unlimited
selection of turtles.

We were extremely well looked after by the staff at
Kapalai, the food was good, the weather warm but really
quite windy (which keeps the huts cool at least).

Trip of a Lifetime

The trip was well organised, everything went just like
clockwork but was very relaxed at the same time. So if
you get as far as Singapore I stringly recommend you
contact Stella at Waikiki Divers and let them organise
the trip of a lifetime for you.

Medical considerations for child and adolescent SCUBA divers

SCUBA Diving News Feed (RSS)

A new report in Pediatr Emerg Care condiders the medical implications for young SCUBA divers. Worldwide, more than 1000 scuba (self-contained underwater breathing apparatus) diving injuries per year require hyperbaric recompression. Approximately 80 to 90 fatalities per year are reported in North America. On average, there were 16 diving injuries requiring recompression in scuba divers aged 19 years and younger in North America between 1988 and 2002. The youngest injured diver was 11 years old and the youngest fatality was 14 years old.

Journal reference: Pediatr Emerg Care, October 1, 2005; 21(10): 681-6.

Creature of the Month: Hermit Crab, Dardanus species

SCUBA Diving News Feed (RSS)

Hermit Crab

Hermit crabs scuttle about the sea-floor using someone else's
shell for a home. They always use empty shells and never
kill the original occupant.

When the crab becomes to large for its shell, it looks for
another. When it finds a likely looking one it will
try it on. If the shell doesn't fit, or is too heavy,
the crab returns to its old shell and continues it search.

Where there is a large population of hermit crabs and
a shortage of shells, the crab will accept a sub-standard
home: maybe a cracked or uncomfortable shell. But in good
conditions it will be very particular about the new shell
it chooses. Two hermit crabs will fight for the possession
of an empty shell, or even a shell inhabited by one of the
combitants.

Some of the Dardanas species of Hermit crab stick sea
anemones on their shells. This camoflauges the crab and
the stinging cells of the anemone protects the crab from
predators such as octopus.

The anemone also benefits from the arrangement. It becomes
effortlessly mobile and shares the crab’s meals.

Dardanas species are nocturnal with dark-adapted eyes.
Look out for them on night-dives in the Indian and
Pacific oceans.

The Simple Guide to Commercial Diving

SCUBA Diving News Feed (RSS)
The Simple Guide to Commerical Diving
Are you thinking about a career in commercial diving? If so read "The Simple Guide to Commercial Diving". Barsky and Christensen's book covers the skills and attitudes needed by a successful commercial diver in a straight-forward and forthright way.

The book starts with a scary warning page before you even get to the contents, summarising the physical and emotional dangers of commercial diving. Once you get past that it describes the training you need to be a commercial diver, the types of work the divers do, the equipment used and the the attitude you need to be successful. The book is amply illustrated with 160 black and white photos and diagrams.

At the end of each chapter the authors elegantly illustrate their points by recounting their own experiences: foolish dives they shouldn't have done, near misses, equipment failures...

If one of the lines in the book is true: "The more you know the longer you live" then any aspiring commercial diver should buy this book for the insight and advice it provides.

The Simple Guide to Commercial Diving is available for $25.46 from Amazon.com at http://www.amazon.com/ and also from Hammerhead Press for $29.95 at http://www.hammerheadpress.com/

Divers call for crocodle warning devices

SCUBA Diving News Feed (RSS)

Divers in northern Australia, are calling for development of crocodile warning devices following the second fatal attack in under a week.

About a dozen people have been killed by saltwater crocodiles in Australia in the past 20 years.

The numbers of crocodiles have increased rapidly in recent years, due to a ban on hunting passed in the 1970s. The deaths have also reopened debate as to whether limited limited hunting should resume.

The saltwater crocodile (Crocodylus porosus) is the largest living reptile in terms of mass. There is a large population in Australia, with the majority being in the Northern Territory.

Shark Travels from Africa to Australia and Back

SCUBA Diving News Feed (RSS)

A great white shark, nicknamed Nicole, has made the journey between South Africa and Australia and back in under nine months. The new research published in Science is the first proof of links between populations of different continents.

"This is one of the most significant discoveries about white shark ecology and suggests we might have to rewrite the life history of this powerful fish," said researcher Dr. Ramon Bonfil, shark expert and lead author of the study. "More importantly, Nicole has shown us that separate populations of great white sharks may be more directly connected than previously thought, and that wide-ranging white sharks that are nationally protected in places such as South Africa and Australia are much more vulnerable to human fishing in the open oceans than we previously thought."

The story of Nicole began on November 7, 2003, when Bonfil and his colleagues from the Marine and Coastal Management Department of South Africa and the White Shark Trust attached a satellite tag to Nicole’s dorsal fin as part of a large study on white shark migrations. The tags—specifically known as pop-up archival tags—record data on time, temperature, water depth, and light levels as the shark moves through its habitat. On a pre-recorded date, the tag detaches from the shark and floats to the surface, where it transmits its data sets to a researcher’s computer via satellite.

An additional 24 white sharks were tagged with similar tags and seven more with real-time satellite tags during this study, with Bonfil and his team often having to wrestle the dangerous sharks while on a cradle in order to fix the satellite transmitters to their dorsal fins. While most of the tagged white sharks revealed at least three different movement patterns, including wide-ranging coastal migrations up and down the eastern side of South Africa, Nicole headed out into the vast and deep basin of the Indian Ocean. The track estimated from the data transmitted by the tag revealed that Nicole followed a strikingly direct route towards Australia, on a path void of oceanic islands. Although Nicole took frequent plunges to depths as great as 3,215 feet (980 meters—a record for white sharks) while crossing the Indian Ocean, she spent most of her time (61 percent) swimming along the surface, leading researchers to suspect that perhaps great white sharks use celestial cues for transoceanic navigation.

Ninety-nine days later, Nicole was swimming about a mile from shore just south of the Exmouth Gulf in western Australia, where her tag detached and floated to the surface with all of her secrets.

This leg of the journey alone—some 6,897 miles (11,100 kilometers)—was one for the record books. However, Nicole would resurface again on August 20, 2004, not in Australian waters, but back in Gansbaai, South Africa, where she was tagged just under nine months before. Her distinctively notched dorsal fin was photographed by Michael Scholl, one of Bonfil’s team researchers and compared to previous photographs he had taken over a period of six years. After a detailed comparison of images of dorsal fin notches and markings, there was no longer any doubt: Nicole had returned to her home waters.

No More Shark Fishing in Red Sea

Whitetip Reef SharkA recently issued Eyptian decree will finally ban shark fishing in the Red Sea. This gives the conservation association HEPCA the legislative means to put a stop to the dozens of shark massacres that are reported daily throughout Egypt's Red Sea coastline from Hurghada to Marsa Alam

Shark fishing has, theoretically, been illegal since 1973, when Egypt became one of 100 countries to sign the CITES (Convention of International Trading of Endangered Species) Treaty. Sharks in the Red Sea were on CITES' list of endangered species, but the Egyptian law that regulates fishing made no mention of sharks.

"Sharks are a valuable source of revenue for the country. Many people don’t realize that tourists spend millions of dollars in the Red Sea because of the sharks. For example, a dive destination like the Brother Islands (off the coast of Marsa Alam) is sold primarily because of its abundant shark population. It has been estimated that each shark in the Red Sea generates approximately 10,000 pounds sterling in income to the country," said HEPCA's Director.

The problem began to reach alarming levels in 2000, when divers and conservationists started noticing a marked decrease in shark populations. The decline in numbers was mainly attributed to an increase in the number of fishing boats in the Red Sea.

This new wave of commercial fishing, coupled with the rise of a handful of trading companies that were being established solely for the purpose of exporting in-demand seafood delicacies (including sea cucumbers and shark fins) to the Chinese market, were an environmental catastrophe in the making.

It is difficult to quantify Egypt’s current shark population and how much it has suffered over the years, but divers claim that sites near Sharm El-Sheikh and Hurghada that have always been known as prime shark viewing destinations are becoming less and less inhabited with by sharks.

Melting of sea ice speeds up in Arctic

After four years of record lows in the extent of sea ice, researchers say the trend can no longer be blamed on short-term variability. Sea ice in the Arctic reached a record low this summer, accelerating a melting trend evident for a quarter-century. The data reveal that the rate of disappearance of ice has now risen to an average of 8% per decade. The figures reinforce previous forecasts that the Arctic is likely to be free of ice during most summers by about 2080.

There remains a question mark over whether the warming is tied to some natural long-term cycle, such as the Arctic Oscillation, which brings warmer air across much of the Arctic. But while the oscillation is currently in a warm phase, this has not increased during the past four years and the suspicion is growing that climate change caused by human activities is to blame.

Climate models predict that global warming will be amplified in the Arctic. This is because as white ice is replaced by dark ocean, the sea surface will absorb more of the sun's radiation and reflect less back into space.

Diving Restrictions Lifted in Greece

Greek MPs have passed in principle new laws to lift restrictions on SCUBA diving. They hope to help make Greece one of the most popular worldwide destinations for scuba-diving holidays. In past years, recreational diving was strictly restricted in Greece in order to deter antiquities smugglers, with diving only permitted in specific, closely-watched locations.

The Communist Party of Greece (KKE) and the Coalition of the Left, Movements and Ecology party expressed reservations about whether the new laws adequately protected submerged archaeological remains, however.

Merchant Marine Minister Manolis Kefaloyiannis stressed that all measures in the bill were fully harmonised with Community law and aimed to allow full exploitation of the favourable weather conditions prevailing in Greece for the greater part of the year, as well as its natural, historic and cultural attractions, to draw the recreational diving sector.

New Research Predicts the Damage from Increased Carbon Dioxide in the Oceans

Increases in carbon dioxide are bad for corals – no matter how you look at it. That’s the conclusion of two researchers in the September issue of the Journal of Geophysical Research-Oceans, who investigated the effects of doubling carbon dioxide on two coral species that are important reef builders in Kaneohe Bay, Hawaii.

“The ocean is known to absorb carbon dioxide, causing measurable changes in seawater chemistry of the surface ocean,” said Chris Langdon, associate director of the National Center for Caribbean Coral Reef Research and one of the paper’s authors. “If this process continues to increase at the current rate, we expect carbon dioxide levels (and consequently the acidity of the ocean) to increase 200-300 percent in the next 50-100 years, so it is important to learn how these changes might affect marine ecosystems.”

Langdon and his colleague and co-author, Marlin Atkinson from the Hawaii Institute of Marine Biology, found that this manipulation of seawater chemistry, carefully designed to mimic conditions that might happen in the next 50 to 100 years, significantly damaged the coral. Langdon and Atkinson observed a 50 percent decrease in skeletal growth at the same time that the photosynthesis of the guest algae within the coral increased. The results indicate a breakdown in the normally mutually beneficial relationship between this guest algae and host coral. A similar breakdown has been widely reported when corals are exposed to elevated nutrient concentrations.

Competition for carbon between the algae and the coral may be the explanation, Langdon said.
While this study did not examine the effects of elevated water temperature associated with global warming, this is also known to be a result of increased carbon dioxide levels in the atmosphere. Scientists predict global ocean temperatures to increase two to five degrees Celsius by the year 2100. “Because many species of coral are already growing very near their thermal threshold, any warming will reduce their growth,” Langdon said. “The combined effects of global warming and ocean acidification on coral growth could be even worse than what we observed in our study. A major unknown is whether corals possess the capacity to adapt or acclimate to these environmental changes, if the rate of change is not too fast.”

Divers in Australia may need New Licence

THE NSW government is considering establishing an annual licence for scuba divers similar to that required by fishermen. The Primary Industries Minister Ian Macdonald said the scheme would involve the creation of an independent scuba diving trust, made up of industry members, who would allocate licence costs to programs to improve amenities for divers.

The trust also could invest funds towards programs to protect the habitat areas of the critically endangered grey nurse shark.

"The state government was previously considering introducing a fee to dive in these areas but the licence system will be simpler and fairer – instead of paying a fee for each dive in the habitat sites, divers will now have an annual fee," Mr Macdonald said.

He said he had recently met senior diving industry representatives, who expressed support for the proposal.
