What I think (/hope) they may be intending with this schedule is to squeeze
in a dive during what should be the surface interval for the deeper divers,
intending that the people who did dive #1 could sit out #2 and then go on
#3 and maybe skip #4 or #5 if their group letter was getting too high.

If you're putting people in the water all day, you can run a lot more
dives than any individual diver can do without a whack of a lot of
decompression, although it seems evident they're not standing in the way
of anyone who's willing and capable of going that route.  A good computer
can correctly figure out shallow-to-deep as well as deep-to-shallow,
although the tables are a lot more simplistic and you have to be nice to
them and do your dives their way.

On the other hand, if you're an NDL diver, it looks like the second,
fourth, and night dives might be your package.  You're hopefully not doing
that first dive on an OW-I card anyway (or really anything short of AI or
DM, with a fair bit of deep experience), and even the third dive is really
an advanced dive.

I agree that you should read a lot before you start buying
equipment, but in my experience (maybe I was lucky), keeping
a marine tank was a fairly easy thing to do.

I started with a 20 gallon marine tank, which many people said
was just too small.  Maybe I was lucky, but I had no problems
whatsoever.  I had several small fish (damsels and dominos, which
btw cost around 4 bucks in NC; however they do tend to want 
to eat one another).  I had a sea urchin, a small starfish,
a flaming scallop (starfish was much smaller than scallop),
an anemone and clownfish, and a puffer - all in a 20 gallon 
tank with a couple of fair sized pieces of coral.

I later went to a 125 gallon tank.  I found there was much 
more work involved (imagine a 25% water change - thats >30 
gallons - hard to do with a couple of buckets).

Anyway, IMHO, a 30 to 40 gallon tank is ideal.  You can have
a good variety of marine life, it doesn't take up THAT MUCH
room (my 125g tank was over 6 ft long!) and will provide you
with a beautiful addition to any room!

So, read up and go for it!

Following the recent thread of discussion on sharks in this group, I opened
my newly arrived April '92 edition of Ocean Realm (it takes a while for this
to make it to the Antipodes) to read of a decision by the State House Marine
Resources Committee of Hawaii to invest $200,000 on the eradication of
tiger, gray and Galapagos sharks in near shore waters.  The article claims
this is in response to the first fatal shark attack in over thirty years.

Does anyone have any details on how they plan to do this?
Without knowing anything about the Hawaiin conditions, this eradication plan
sounds like an over-reaction to me.

I've never dove in California, so I'm not sure what you're used to, but 
Oregon and Washington have some excellent diving opportunities.  As a 
photographer, I prefer the protected waters of Puget Sound to the high current
diving off the Oregon Coast.  There are two good books you should look at,
141 Dives by Betty Pratt-Johnson and Northwest Shore Doves by ??.  Anyway,
the water is cold, but most divers have no problems with a full 1/4" wet
suit.  The best visibility is in the winter, when the algae isn't so thick.
Right now there's a layer of bad visibility at about 25-35 feet, but if you
drop below that layer, the visibility increases dramatically to 30 feet or
so.  Good luck!

By the way, is there anyone in the Seattle area that would be interested in
telling me what I need to know about diving the Narrows, or better yet,
be willing to let me accompany you on your next Narrows dive?  I've heard
about the currents...

To some extent, it is only reasonable to expect this kind of behavior
from mags that accept advertising; after all, offending their advertisers
may lead directly to loss of revenue.  There may be better ways to handle
it that SDM does (proposals, anyone?), and there may even be mags 
available that do a better job than SDM, but the only way to get
Consumer-Reports-level objectivity is to set up a Consumer Reports.
They don't accept advertising and they don't allow their reviews to be
quoted in advertisements.  They don't accept donations of review items
or any other perqs.  They are funded entirely by subscriber fees and
maybe foundation grants.  Is the diving community prepared to fund 
a corresponding entity for ourselves?

What I have heard lately is that reverse profile diving makes micro-bubbles
in the blood unstable. This can cause DCS, even on dives well within the 
tables. There have been some reported cases of DCS on very shallow dives 
(about 12m, 36 ft.) of about 30 min's. The newest theory I have heard is that
multi-level dives can cause DCS even without coming close to the limits as
well as multiple dives over several days. The advice given was, The first 
dive should be the deepest, you should spend aprox. 10 - 15 min's at 1/2 
the deepest depth. This should stablize the micro-bubbles for about 1 week.
If you go on a deeper dive latter in the week, then you should repeat the
above dive profile. This came from a german dive mag, but the author was 
someone in ca. in the good old USA.

Note: I will be gone next week, so I won't see anything posted for the next
5 days or so.(even though I manage news here there are limits to my freedom)

I was talking to a friend in Ohio this week and she told me of two accidents
at the Gilboa Quarry in North West Ohio recently.  According to her, one diver
was at the deep end of the quarry (120 feet) and suffered a regulator freeze
up.  He apparently made a rapid ascent and suffered barotrauma requiring a
lifeflight to the hospital.  In the second incident a man and woman team were
in the deep water when the woman signaled she was out of air.  The man started
to surface and when he failed to see his partner, returned to the bottom and
re-located her.  She at this time signaled she was OK, but they should surface
anyway.  Again, he started to surface but lost sight of his partner.  This
time when he returned to the bottom he could not find her.  She was found
several days later in the deep water.

This information is word of mouth and could be inaccurate.  If anyone has
additional information please feel free to correct me.

Watersport Publishing strikes again!

I believe that the reference to _Women_and_Diving_ is actually _Women_in_Diving_
by Erin O'Neill and Ella Jean Morgan (aka O'Neill-Morgan).  The book is an
expansion of a series of articles that appeared in _Discover_Diving_ magazine
a few years ago (this series has been the basis of most of my class discussions
on "Women & Diving").  I just ordered a copy.

If you can't find it in a local dive shop, you can order it from Watersport
Publishing for $12.95 (they will accept phone orders).

I've been reading this group for about 2 months now, and followed
the "beginner afraid of sharks" thing for a while.

I was just in Hawaii for three weeks, and saw my first shark.
As could be expected, I freaked out at first.  I saw it and my brain
went "SHARK!  AAAAAAHHHHH!!!"  After I calmed down, though, it was really
tempting to get up closer and maybe even touch it.  It was just sitting
there, doing nothing, going "duhhhhh..." (in shark-speak, of course)
It was really beautiful, in a way.  Not a particularly aesthetic
animal, but when I thought about it, it looked so harmless and yet could
have bitten off my arm if it had really wanted to.  It's like watching
the surf on a rocky coast:  It's pretty to watch, but you don't want to be
IN IT.

The moral of the story is, the biggest danger inherant in most sharks is
that they'll give you enough of a scare to drop your regulator beforre
you collect your wits.  Don't worry about it.

Summary: Dive trip on board Bilikiki for 10 days in Solomon Islands
Keywords: Solomon Islands, Bilikiki

     Wind and salt spray hurtled past the cockpit as the giant B-17 skimmed
the surface of the South Pacific just outside of Henderson Airfield.  It was
mortally wounded, and I was trying to save it along with the crew.  We had
been North bombing Rabaul, and on the trip home we had been attacked by
Japanese Zeros.  One wing was shot nearly in half and the other was on fire.
We were close to the surface now, and the waves were beginning to lessen our
air speed.  Just a little closer to land!  As I dropped the nose into the
ocean, the water exploded up over the top of the plane in a plume of white and
green.

     The stewardess was leaning over me mopping up the steaming hot tea, she
had just spilled into my lap, startling me awake from my day dream.  Once
again I had dozed off thinking about the upcoming trip to the Solomon Islands
in August of 1993.

     The trip is still twelve months off, and yet I am excited about it.  This
will be **the trip** for '93. :-)

     The trip begins with two days of exploring the Japanese wrecks off of
Guadacannel.  There will be two dives each day on these wrecks with Island
Dive Services.  We will be staying in the Mendana Hotel for the shore based
portion of this trip.

     The highlight of the trip is ten days of diving the Solomon Islands from
the world class liveaboard **Bilikiki**.  Under Current Magazine rated the
Bilikiki and Solomon Islands 5 *s across the board.  Renowned underwater
photographers Chris Newbert, and Stan Waterman have scheduled three months of
trips on the Bilikiki for 1992 and 1993 which are already full.  The magazine
"SCUBA Times" called the Solomons the ***EPICENTER OF THE MARINE WORLD***.

Trip Includes:    -- Airfare from SFO to Honiara, Guadacannel
             -- Hotel and 4 beach dives on wrecks in Guadacannel
             -- 10 nights on Bilikiki diving the Russel and New Georgia groups
             -- Transfers to and from the airports, and stopover in Nadi Fiji.

Trip Costs:  $4500.00
             $ 300.00 Deposit  required to hold your spot
             The rest paid in installments between now and June 1993.

     This is our second trip to the Solomons.  They were so spectacular the
first time that we had to do a repeat performance in August of 1993.  This
trip will be the highlight of an divers logbook!!!  8-)

     The next trip meeting is scheduled for 30 Nov 92, at 7:30 pm at Any Water

  Actually, the situation Steven describes sounds exactly like the PADI basic  
open water guidelines.  A PADI instructor who recommends daytime-only dives  
with a 60' depth limit for graduates of the basic class is not an exception;  
s/he is following the rules.

According to a recent dive article I read (I think in Scuba Diving, the
new mag from Rodale), use of scuba in Greek waters is illegal except for
accredited researchers.  This is intended to stop treasure hunters and
collectors from taking items from some of the submerged ruins.

I don't know much else about Med diving except it is said to be cold in
there, compared to the Gulf of Mexico/Carribean.
