	Hello,

	As it seems now, I'll be spending some time in Portugal this

	So, any info on dive-operators / dive-sites / dive *.* is
	appreciated... very much in deed !

	Also any other DO's & DON'T's ..... well you know...
	
	Preferably by e-mail, but I do read this GROUP(er) too...

How much is too much? Are you getting only half an hour out of a tank at moderate depths? How much is involved here? I know I use air very fast, compared to a 
woman, but that's because I'm 6'4" 210 lbs. Last weekend I, two other men, and
a woman (coincidently named Susan) did a 98' 25 min dive with a five minute
saftey stop. We all had full tanks ~3000 psi. After the dive, I had 800 psi, my
buddy had 900, the other man had about 900 psi also. Susan had 1800 psi!!!
She was peeved because we had to go back and get new tanks! (We needed the sit
time anyway!) 
My main question then is how much are you taking, and are you diving with slightmen, or women? If you are out breathing average size men, and you are anaverage
size woman, you may need some work, but really it does get better.
My first tank lasted about 40 min at 40', Now I can get slightly over an hour
and I've only had about tweleve dives! Sommeone else also mentioned BC. Fight
bouancy, and other stress are very significant, remember to breathe long and slow to get that good exchange.

Luck,

I've since received some e-mail on this from David Hunt 
(David.Hunt@GANGES.EDRC.CMU.EDU) who says that he and others
have written to Hawaiin officials and been assured that there
is no such plan to eliminate sharks.

Shark control isn't something isolated to Hawaii.  Sydney beaches
were first meshed to prevent shark attacks in 1937, and there has
not been a shark fatality on a meshed beach since then, although
fatalities have occurred on unmeshed beaches and in the harbour.

I've heard that the problem with the meshing is that it doesn't
discriminate between large marine animals, and more than sharks
are killed in it.  The Sydney experience might also bade against
any eradication plan.  In the 1950s a bounty was put on sharks
(1 Guinea per dorsal fin from memory).  This offered such an
encouragement to hunters/fishermen that the grey nurse population
off Sydney, which never really posed a threat to the land population,
was decimated.  The result was that in the 1980s the grey nurse was
declared a protected species in Sydney waters, in response to its
endangered position in the area.

JR>Does anybody know of a recent diving accident at the Andrea Doria?

There have been two seperate incidents. One involved a fairly experienced
CA diver, the other an equally experienced NJ diver.

JR>Is this wreck even a common dive site?

It used to be the ultimate challange for a few hardcore NY/NJ wreck diver.
Few captains took the long ride and wanted the liability. The R/V Wahoo
required several deep dives with that dive operation before you were 'invited'
to join in on a 'Doria' Trip (if AT ALL).

Today, anyone with the money and time can find some captain who'll provide
transportation to the site. There's a lot of concern among the wreck diving
community about the unsafe practices currently becoming common when
diving the Doria.

JR>A friend of a friend's husband was reported to have died in a recent 
JR>diving accident at this site.

Sorry for your friend. But no matter HOW experienced that husband was in 
his particular locality - he is just a beginner in the local conditions
(current, visibility, temperature,...) of NY/NJ. You can't just fly over,
jump on a boat and dive the Andrea Doria. The depth exceeds any 
conservative safe limit for Nitrogen Narcosis AND O2 Toxicity. And if you
want to dive on mixed gases, then the Doria is NOT the site to gain
first experiences. 

The Doria allows for extensive wreck penetrations in limited visibility
and requires the diver to be utmost alert, totally comfortable with local
conditions and equipment.  NOT a vacation dive, but rather a demo site for
Darwin's law and how it applies to Scuba Diving.

You couldn't pick a better place to dive! I have fished, rafted, kayaked 
this portion of the river numerous times and it is absolutely beatiful!

One problem/caution that might apply to diving, I know it did to fishing, 
rafting and kayaking, is that the river fluxuates greatly. While camping
on the shores we were very careful to pull our equipment very high on the
shore to avoid losing it.  I have seen the river rise serveral feet over
the course of a few hours due to the release of water from Flaming Gorge.
This also causes the water to get murky.

Last time I was fishing there we caught some good size rainbow and german
brown trout (3 to 8 lbs.), so take along a fishing pole if that is your 
thing, you won't regret it.

I don't know what the altitude is there, but that is one definite thing
to consider.

You forget the primary purpose for which damsels are sold is to cycle tanks.
Because there part of the orignal sale (almost) it is in the interest of shop
owners to keep the price down.

Also usually damsels are returned after about 1 month and traded in on the more
expensive, higer margin fish.  This keeps profits up and also allows the same 
damsel to be resold many times.

As many folks have mentioned, hypercapnea (excess CO2, could be the
culprit).  Taking a deep breath and flushing the lungs out every few
breaths will help.  Additionally, sinus problems could cause
headaches, and so forth.  One thing that happens to many new divers is
TMJ, or something related.

I once had a severe CO2 headache, caused by trying to sleep on a
poorly ventilated car, under a hatchback.  It seemed to mostly be a
general dull ache, centered in the back of my head.  Sinus headaches
mostly seem to be in the front of the head.  If you have headaches
right in the top of your head, they could be simple tension headaches,
or possibly TMJ related, caused by something quite simple:  Holding
your regulator mouthpiece too tightly in your mouth.  

My belief is that clenching your jaw can cause muscles on the top of
your head to tighten up and begin to hurt.  In some animals, such as
dogs, the jaw muscles seem to be directly attached to the top of the
head.  I don't think that there is much action imparted into the human
jaw from those muscles, but I believe they tense when you clench your
jaws. 

There are also people who have some abnormality in their jaw joints.
Try this simple test:  Look in a mirror, and open and close your jaws.
Watch the tip of your chin.  Does it displace laterally at some point
during the action of opening and closig your mouth?  If so, you may
have TMJ:  See your doctor for a confirming diagnosis.   TMJ can cause
severe headaches, earaches, jaw pain, and so forth.  These actions can
be aggrivated by scuba.

What can you do?  If it is a mild case, a better mouthpiece might
help.  Widely suggested is the U.S. Divers comfo-bite, which has an
arch in it that keeps you from having to clamp down on the reg.  There
are other expensive mouthpieces.  

One simple tip is to just not hold your mouthpiece as tight.  Just
tight enough not to drop it.

I myself lean more toward ZEN tendencies.

Be as one with the aquatic environment.
Cause no harm (Fire Coral is mighty powerful instant KARMA).
Breathe slowly and deeply as you meditate.
Move gracefully and serenely with efficiency and purpose.
Seek and embrace knowledge - for enlightenment is the key to understanding.

Standard neoprene dry suit do well down to about 50-60fsw where the rubber's
air cells crush enough to loose insulating power; vulcanized rubber "shell"
suits (like Viking) don't have this problem.  If you don't move much
(photographer or researcher), you are small, or just usually dive "cold",
this difference could be accentuated.  However, neoprene dry suits are
far less expensive that the "shell" suits. 

The new, "crushed neoprene" dry suits should fall somewhere between the
standard neoprene and the vulcanized "shell" suits in price/performance.

Watersport Publishing publishes a good book on all types of dry suits and
dry suit diving by Steve Barsky, _DRY SUIT DIVING_.  Check your local dive
stores for a copy.

For the record, I dive with a Viking Sport dry suit (vulcanized rubber "shell"
with insulating underwear).  But if I were to buy a neoprene dry suit, SAS
would top my list due to raves/recommendations from people who use them 
(besides, they are the *best* looking dry suits on the market).
