Thanks!

Diving with Dugongs: Marsa Alam, Red Sea
========================================

Around 10 years ago I stayed in a tent in the desert and 
dived every day up and down the coast.  It was the most 
relaxing holiday I've ever taken.  A mix of nationalities 
ate together each evening in the communal tent, and 
agreed that the Egyptian Cleopatra wine was just as bad 
as it had been the night before.

The place was Marsa Alam and this year I went back. This 
time I flew into the recently built airport, was whisked 
to my hotel and air conditioned room.  We drove past my 
original campsite but I didn't recognise it at first as 
an "eco village" had been built. The coast which we'd 
travelled up and down in a pickup truck, and that had been 
nothing more than desert, had been carved into 
hotels and resorts.

But what about the diving?  Marsa Alam is very close to 
Elphinstone Reef.  This is a fantastic dive site, 
featuring deep pinnacles and a very deep archway 
concealing a sarcophagus-shaped rock.  There is always 
the possibility of seeing sharks, dolphins and turtles.  
It has steep walls and shelving plateaus, including one 
at around 5 m so plenty to see at the end of the dive. 

If you are staying at Marsa Alam you take a day boat out 
and do 3 dives on Elphinstone.  However, you may have 
a 30 m depth limit, which on this dive I consider a 
serious limitation.  With Emperor Divers' day boat, the 
two first dives are very close together (1 hour surface 
interval).  You've barely time to warm up after the 
first dive when it's time to start kitting up for the 
second.  Also, the day boats wallow in the waves so the 
two hour journey can lead to sea-sickness.

The other dive sites are closer inshore. They are 
generally pretty, with good vis and swim-throughs.  
Especially interesting is the nearbye Abu Dabab where 
dugongs may be seen.  However, as many people swim 
with the dugongs - snorkellers as well as divers - 
it will probably not be long before the dugongs 
are driven away.

If you would like a hotel-based holiday with 
uncrowded dive sites, Marsa Alam is the place for you. 
If you want to take your time diving some of the best 
sites in the Red Sea, then you would be better off 
taking a liveaboard.  One which visited the Brothers, 
Elphinstone and Daedalus would be a good choice, 
or one going further south perhaps.

Where to Stay
-------------
For people with partners or children who don't dive the 
Kahramana hotel is a good choice.  This is a sprawl of small 
buildings, each one comprising two or four rooms (a room 
being a large bedroom, bathroom and hallway).  There 
is plenty to do: horse and camel riding, beach volleyball, 
tennis courts, two swimming pools, two beaches and a 
children's playground.

As you will not be near a town, paying a little extra 
for a hotel with three restaurants plus bars and 
bar-snacks is definitely worth it. They've managed to 
convert the desert into a garden with a huge array of 
gardeners keeping the plants healthy.  Palm trees have 
been planted on the beaches and the buildings are the 
same red and ochre as the desert sand.

Creature of the Month: Dugong (Dugong dugon)
================================================

About 50 or 60 million years ago, a group of animals 
related to the elephant moved to the coast marshes.  They 
spent more and more time in the sea until eventually they 
lived most or all of the time there.  These were to become 
the present day sirenians - manatees and dugongs. 
Sightings of these were thought to have inspired the 
myths of mermaids.

Also known as a sea cow, Dugong's feed in the seagrass 
beds of the Indo-Pacific.  They are the only 
herbivorous, truly marine mammal.  (The related manatee 
spending some of its life in fresh water.)

You'll find dugongs in sheltered lagoons and bays rich 
in seagrass, in warm water such as are found in the 
Red Sea, East Africa, Japan, the Philippines and 
Australia.   

They have dense, massive bones, which help to keep them 
submerged.  Their lungs lie along their back and act 
like floats, keeping them horizontal in the water.  
They can eat as much as 40 kg (88 lb) of seagrass 
a day, leaving distinctive troughs in seagrass meadows.

Adult dugongs can grow to over 3.5 m (11 ft), and may 
weigh over 900 kg (2000 lb).  They can travel several 
hundred miles in a few days, through the waters of 
many different countries. 

Male dugongs begin to grow tusks between the ages of 
12 and 15 years. If food is plentiful, the habitat 
protected, and predation low, dugongs may live more 
than 70 years. 

Dugongs are thought to use the "lek system" whereby 
males establish and defend courtship territories 
in traditional areas where females come only to mate.

Dugongs are natural prey for sharks, killer whales, 
and crocodiles, but they are most vulnerable to 
human activities. Hunting has drastically reduced 
dugong populations in some areas.  Dugong habitat 
is under pressure from coastal development, 
pollution and other degradation.

New Article Discusses SCUBA Diving Medical Conditions
  Immersion in water increases the load on the heart 
  with a rise in both cardiac output and blood pressure. 
  Exposure to cold and increased oxygen partial pressure 
  during SCUBA diving also increase heart rate. Any 
  history of cardiac disease or abnormalities detected 
  during the routine medical examination should prompt 
  further evaluation and specialist referral.

Scuba Diver Killed in Shark Attack in California
  California has recorded its first fatal shark attack 
  of the year. The US Coast Guard has recovered the 
  headless body of the diver killed Sunday off the 
  coast of Northern California.  Randy Fry was 
  attacked in shallow water by a shark estimated to 
  be up to 18 feet long.

Dead Zone Spreads across Gulf of Mexico
  Water so devoid of oxygen that sea life cannot live 
  in it has spread across 5800 square miles of the 
  Gulf of Mexico this summer, in what has become an 
  annual occurrence caused by pollution.

16 Hour Swim to Protect Dive Spots
  After seeing some of his favourite dive spots 
  deteriorate, a 61-year-old Texan decided to swim the 
  rough Caribbean waters between Cozumel and 
  Cancun to promote the protection of coral reefs. 
  The crossing is 14 miles longer than the English 
  Channel.

Fishermen can Reduce Turtle By-Catch
  Fishermen who use large circular hooks baited with 
  fish rather than squid may not only boost their 
  catches, they may also significantly reduce the 
  number of turtles killed and harmed in fishing gear 
  every year.  The booklet, 'Catch Fish Not Turtles 
  Using Longlines', is available online at 
  http://www.wpcouncil.org/
 
India Trust Acts to Save the Whale Shark  
  The Wildlife Trust of India (WTI) has launched a 
  project along the Gujarat coast to save the 
  whale shark.  Its numbers have shown a steady 
  decline owing to illegal hunting.  Whale sharks 
  undertake long migrations.  They come to the Gujarat 
  coast annually as part of their migration routine.

Conservation of Sea Cucumbers Victory in Galapagos  
  Ecuador's highest court struck down a ruling that 
  undermined limits for sea cucumber fishing in the 
  Galapagos islands, in a victory for environmentalists 
  fighting to conserve the species.

Military sonar harms Whales, says new report
  Sonar used by the military to spot enemy submarines 
  is to blame for increasing cases of whales being 
  stranded on beaches and dying, the scientific committee 
  of the International Whaling Commission (IWC) said in 
  a recent report.
  http://www.enn.com/news/2004-07-23/s_26126.asp  

Whale Strandings Theory
  An analysis of data collected over more than 
  80 years in Tasmania has revealed that a 
  disproportionate number of whales and dolphins 
  beach themselves in the region every 10 to 12 years. 
  The strandings appear to be triggered by a 
  climate phenomenon called the zonal westerly winds. 
  The information will be useful in preparing volunteers 
  to deal with the strandings.

Mexican Prosecutor investigates Turtle deaths
  The discovery of 125 dead sea turtles snared in 
  an underwater net will be investigated to find out 
  who was responsible, Mexican prosecutors have 
  announced.
