Citizen Dive Watch

  Good Morning (at least here in Asia!),

  Have any SCUBA News readers had any experiences,
  good or bad, with Citizen Watch Company's Aqualand
  dive computer watches?  I'm particularly interested in
  their Nitrox watch but, as my concern is one of easy
  of interpreting so small a display, ability to
  accurately discern what it's telling you quickly, and
  how well it functions in switching modes, comments on
  any of their computer dive watches would serve as a
  good model.

  Thanks

  recommend any diving shool which would help me finish 
  my certificate. we are looking to stay a week to 
  10 days in the beginning of July. Furthermore any 
  locations you think are a MUST ?

  Thanks

Bookshelf: Interview with Joyce Huber 
=====================================

Joyce Huber is the author of a travel guide for divers 
titled Best Dives of the Caribbean.  This 
was first published in 1988, but an updated version is 
out in May. 
 
This first diving book spawned another on the sea - 
Best Dives' Snorkeling Adventures.  This came about 
when she put her email address in an edition of the 
diving book, and was inundated with questions.  Not 
from divers but from snorkellers. 

After many nights staying up until 3 am answering the
e-mails, Huber decided the snorkellers should have their 
own book.  Her publisher, Michael Hunter, didn't see a 
market in snorkelling, but she had worked in print for 
so many years that it seemed simple enough for her to 
put a snorkelling guide together for them.  It is now 
in its third edition. 

Her scuba diving guide has been in need of an upate 
for a few years - but she put it on hold as her 
co-author/dive buddy/husband was diagnosed with brain 
cancer in 2002.  He died in 2003. She was so devastated 
she did nothing till 2005.  His name as co-author is on 
the new edition of the guide as he contributed much time 
to it. 

The first dive book was the result of 20 years of dive 
travel and note taking.  Back in the 1970's, Joyce and 
her husband Jon put on slide shows of underwater 
sites for their local dive club.  Friends asked about 
places to stay, best time of year, where to eat etc. 
It grew into a book from there. 

Joyce signed a contract with Dodd Mead publishing, but 
the publishing company folded.  Putnam Publishing bought 
out the contract. They dropped "Best Dives".  Since she 
was a new writer, she hired a crusty editor - Eliot Tozer 
- to make the book more saleable. He got hooked on the 
subject and took off for Bermuda for a resort course.  
He nearly drowned when his mustache let water in his mask. 

Simon and Schuster's editor then wanted the book, but 
she was over-ruled as no one had ever published 
a dive-travel guide and they didn't want to be the first. 
Meanwhile, Michael Hunter started a travel book company. 
He moved to south Florida and lived on the beach where he 
saw lots of divers going in and out of the ocean so he 
figured there must be a market.  He published the first 
Best Dives book in 1988 and it was an instant success. 
"We meant it to be for new divers" says Joyce "but 
everyone loved it."

You might imagine that writers on diving have been 
a major influence on Joyce Huber, but oddly enough 
she sites instead people from Flying Magaine and 
Aviation International News.  She worked on aviation 
magazines as an art director for many years and in 
corporate and general aviation doing promotional 
work. She is a licensed seaplane pilot.

Huber grew up in northeastern New Jersey, an area 
that is a suburb of New York City.  She spent summers in 
south Jersey swimming and beach-combing and watching 
seaplanes. After studying art at Pratt Institute and 
the Art Students League she worked as everything from 
a fashion designer to a mural painter. She went back 
to school for writing specifically to do the dive 
books when she was 35 years old. She's now 58 now. 

Joyce Huber's books are available from Amazon, with 
up to 35% off.

Did You Know? Coral Reef Facts
==============================

The plural of fish is "fishes" when referring to a group 
that consists of more than one species, but "fish" when 
referring to a group that consists of just one species.

Creature of the Month: Tube Sponge, Acervochalina sp
=====================================================
Tube sponge, copyright Tim Nicholson, SCUBA Travel
For a photo of a Tube Sponge see
http://www.scubatravel.co.uk/sponge.html

Sponges are amongst the simplest members of the animal 
kingdom.  They have no digestive, nervous or 
circulatory systems for example. 

The lack of sophistication in sponges has been shown in 
a classic experiment.  A sponge was pushed through fine 
silk to completely break it down.  However, it soon 
succeeded in resassembling itself.

A sponge feeds by drawing water into its central cavity 
through its pores - the tiny holes covering its body.  
The filtered water leaves through the big outlet pores.

With their varied colours and intricate shapes, sponges 
add beauty to the reef or rock.  Some sponges are 
greenish, violet or pinkish in colour because they 
harbour symbiotic algae.  The more symbionts and light, 
the stronger the colour.   When there is low light 
these sponges are a much paler colour - almost 
white.

The sponge uses the algae as a source of oxygen, a 
screen against sunlight and as a food source.  It 
provides the algae with a secure habitat.

Our picture (http://www.scubatravel.co.uk/sponge.html) 
shows a Tube sponge, Acervochalina species. This sponge 
can produce a chemical which is highly toxic to  
Pocillopora and Acropora corals.

Dahab Blasts
  23 people have been killed and 62 wounded in three 
  blasts in Dahab - a town in the Sinai peninsula 
  popular with divers.  After the explosions, dive 
  instructors entered the bay to search for body 
  parts and pieces of shrapnel.

Scientists Discover New Species of Hammerhead Shark
  A recent study into scalloped hammerhead sharks, 
  Sphyrna lewini, shows that although the fish in the 
  Atlantic and Indo-Pacific populations appear 
  identical, genetically they are different. The 
  scalloped hammerhead in the western north Atlantic 
  is actually a different species.

Movements of whale sharks tagged at Ningaloo Reef, Western Australia
  Whale sharks aggregate from March to June to feed 
  in coastal waters off Ningaloo Reef.  According to 
  research published in the journal Marine Biology, 
  the sharks then travel northeast into the Indian 
  Ocean.  They use both inshore and offshore habitats 
  and frequently travel vertically up and down, 
  occasionally to a depth of at least 980 m.  Vertical
  migration over a 24-hour period, and twilight descents, 
  were evident in the depth records.

Sign the El Quseir Charter to Protect Coral Reefs
  Worldwide about 30% of all reefs are badly damaged 
  and additionally 30% are endangered.  Several factors 
  play a role in the damaging of corals reefs including
  changes in climate, rapid developments along the 
  coast and influx of nutrients.  Other problems are  
  over-fishing with gill nets, dynamite and poison and, 
  last but not least, tourism.  Sign the EL QUSEIR 
  CHARTA and undertake to conserve coral reefs.

Tiny Island Nation Creates Third Largest Marine Park
  The tiny Republic of Kiribati, in the Pacific, 
  has created the world's third-largest marine 
  reserve.  The Phoenix Islands Protected Area 
  bans commercial fishing to protect more than 
  120 species of coral and 520 species of fish 
  inside its 184,700 sq km (73,800 sq miles). It 
  is the world's first marine park with deep-sea 
  habitat, including underwater mountains. Kiribati 
  is in the central Pacific between Hawaii and Fiji. 
  It comprises 33 islands stretching across several 
  hundred miles.

China to Establish Reserve for Rare White Dolphin
  China plans to set up its first reserve for the 
  endangered white dolphin off the coast of the 
  southern city of Zhuhai in the Guangdong 
  province. The city has allocated 460 sq km 
  (178 square miles) for the reserve.  Pollution 
  from paper mills, chemical plants and plating 
  factories along the river had been destroying 
  the dolphins' habitat.

Australia Says New Research Proves Scientific Whaling is A Sham
  A new study shows there is no justification for 
  scientific whaling programs under which thousands 
  of the mammals have been killed in the name of 
  research, Australia's environment minister said.
