Judging from the pictures on the U.S. television networks, and
places I recognized from my own trip to Kaui, Iniki made a real
mess of things.  Places that weren't outright blown away will
not have basic services for a while, and I doubt it will be cleared
up by Oct. 9.  The other(more southern) islands appear to have
been completely undamaged so I would switch my vacation to 
one of the other islands(Oahu, Maui, the Big Island) if I was you.  
I've heard good things about Maui and Molokini diving, but haven't
been there myself so can't say much.

I am planning on spending some time in Malta soon.  Accommodations are not an
issue; does anyone have any suggestions or comments on the diving in this 
area?  Dive outfits to recommend?  I've dived primarily on warm-water Caribbean 
reefs/wrecks, and don't know what to expect or look (out) for.  Thanks!

After reading the San Jose Mecury today I would have to say; pick another 
Island. Kauai is not going to the same for many months. Lihue airport is
closed according to the paper. Many tourists are stranded and trying to
leave. And my wife just called to tell me that another storm is hitting
the island. Not something you want to voluntarily get into.

Last January, both my buddy and myself had apparent DCS hits.  The hits 
manifested as pain while at the 10 ft stop.  The pain was located in the
front part of the upper leg (not a joint pain, as is apparently most common).
(Not sure what part of leg on buddy hurt.)  I increased depth for some time
and approached the 10 ft stop again later.  No professional treatment was
sought.  This was an extreme dive on air with more than 80 mins total 
decompression time.  There is no way to tell if these were actually DCS
hits or something else (denial?).  Obviously, if this was DCS, it was fairly
mild.

I've had this fear that you had.  I had an inner ear problem at the
beginning of this year and even though I had not had the vertigo for
many months, I was afraid of the problem reoccurring when I went diving
this July.  I told my husband/buddy that he had better stay close beside
me on this trip because I didn't know what I'd do if I had that awful
dizziness down under. Luckily, I didn't.  Please post any info you get
from the specialist (since he's also a diver).  I'm wondering what
effect diving has on the inner ear -- most problems I've heard about are
the regular kind -- trouble clearing, etc. -- not inner ear stuff.

A part of the same post not quoted by Dave Waller said the guy was in
only 60 feet of water (which is itself doubtful at the Flower Gardens,
from what I hear.) In that case death from DCS, though not impossible,
is to say the least highly unlikely. I would say that what we have here
is typically bad reporting by a newspaper writer who probably didn't
know a thing about scuba diving.

You should probably not include PADI, since it sounds like they have

Being new to Texas I have heard a little about the Flower Gardens.  I would

Any information about the Flower Gardens and dive trips to them would be
greatly appreciated.

I would also like to know if anyone has any suggestions for spear fishing trips
from the TX coast.  Some of the dive shops around here say that I am looking

Allow me to attempt a summary of the preceding posts as a reflection of my
understanding of the advantages of O2-enriched mixtures (including "100%" O2) 
for decompression.

	1)  Better oxygenation: 
	
		With an O2 enriched mixture, the gas that
	    	does get past blockages is richer in O2.

	2)  Better nitrogen elimination: 
	
		O2-enriched mixtures are "N2-impoverished" mixtures.  
		Not only is there less N2 to absorb but the reduced N2 
		in the breathing mixture encourages the N2 in the body
		to off-gas.


Note that most O2 delivery systems cannot deliver 100% O2 due to mixing with
ambient air prior to inspiration.  The best units are carried by paramedics.
Next best is probably a demand-regulator like the DAN unit.  However, when
in doubt, any O2 is better than no O2.

BTW, it is rapidly becoming a "standard of the community" for dive leaders
(instructors, dive masters, dive boats) in California to carry O2... have it
available at the dive site, know how and when to use it, and *actually use it*.

In a day or two you'll be able to see for yourself. Outgassing takes place
in 6 hours. But even then you total NDL is very short (as if you still had
some residual nitrogen on some of the other tables). I think I had posted
some comparison profiles.
 
My quick comparison made me think that they were a combination of PADI RDP
and NAUI revised tables: SHORT first dive (PADI), SHORTER second dive (NAUI),
fast controlling tissue during SIT (PADI), eventually decompression stops
(NAUI). Another factor is, that VERY short SITs or repetitive deep dives
in quick sequence are HEAVILY penalized with longer decompression stops.
 
Overall, I believe the total NDL bottom time for 2 or 3 dives per day
are probably shorter. Multiday dives don't reduce NDL, but flying after diving
essentially is very conservative.

I agree with you on the convenience factor.  I did one of these sailboat
charters in the BVI about 5 yers ago, before I was certified :( .

I remember that there was a dive shop at the dock of the yacht rental
marina ("The Moorings" on Tortola).  Other folks who were obviously
divers would rent about a dozen filled tanks for their week's outing and
stow them wherever they could, often lashed to the stern railing.
What I DON'T remember seeing was alot of places to get airfills without
going out of your way each day.

I'd recommend calling the yacht charter place and asking if they have
a similar arrangement with a dive shop nearby.  These places are used
to catering to the charter sailors.  An alternative would be to inquire
about renting a portable compressor.  In either case, I'd much rather
rent tanks down there than deal with the airlines.

There was a thread earlier here on the topic of flying with tanks.
I think the bottom line was that they had to be completely opened
before checking them, and therfore inspected before re-pressurizing on
arrival.

When I took the DAN O2 administrator course, there was a slide presented
with data about the outcomes of recompression.  About 45% recovered
fully, another 40% were permanently left with minor symptoms and the
remaining folks saw little improvment as a result of treatment (subject
to the errors of my memory).

Note that these numbers are for all groups, so that they included both
those that waited 5 days before admitting they may have been bent, and
those that were treated with O2 immediately and wisked off to a chamber.
I suspect that these variables have a profound effect on recovery, but
were not discussed.

Well, once I spent 5 hours at 250' (I had to ascend when O2 toxicity

badly at 60'.  So you must be wrong, Dave. :-) :-)

There is especially one weak point on the Nikonos IV and V: The O-ring seal
at the shutter speed dial. You can easily service this point yourself.
It a good description on this in "The manual of underwater
photography". As far as I recall there is no need for full disassembly
to do this, just remove the retaining screw at the top.

I did a full service myself after 6 years on my Nikonos IV just in time:
Small leaks at this point had caused some rust in the underlying
spring. No flooding of the camera, just slow degradation. Many of my 
friends had similar problems. I think the probability that this should 
happen is very high if you do not regularly maintain it. Else there
were no signs of leakage. Just maintaining this point every ear could
cause your camera to last another 5 years. Nikonos is a very simple
camera. It is not to hard to service the other o-rings as well.

Thanks for the detailed info. I'm not sure just exactly *what* constitutes
a "minor" symptom, but if it is things like permanent tingling or numbness
of an area, then that would better explain the incosistency in our remarks
-- I lump those people in with the "fully recovered" folk, although this is
admittedly a personal view (I don't consider minor symptoms such as this as
handicapping).

How extreme do you require the tables to go?  Sport diving tables exist from
various sources at the local dive shops.  NAUI Canada will sell both the
NAUI and DCIEM tables (sport version).  For the more extreme, or in water 
O2 decompression tables, photo reduction and lamination seem to be the best 
route.
