Hey man, Let throow some thing to you in slighly larger perspective!

lets just say you have a mason jar - and you found a mound of Black ants
and you pulled off all the limbs to symbolize the electrons of Nitrogen atom
and the heads are the protons (discard the rest of the body) and then you found
a red ant mound and did the same thing to symbolize Oxygen atoms.  Now if you
were to loosly mix the two as to get 78% black and 21% red 1% percent air(to
 represent
1 percent of other gases present) now I want you to jam a couple hundred pounds
of pressure of ant parts in the mason jar then add some more including about
 another
hundred pounds of pressure red parts to symbolize your valued ENRICHED AIR that
everyone seems to be so fond of and then close the lid.  now to copy your
 suggestion:

>mix. It appears as though the gas does stratify, at least for awhile.  We've
>found that either letting the tank sit for several hours, or rolling it
>vigorously will stir up the contents sufficently to homogenize the mix.

Well, yeah thats the ticket - NOT!  Gas molecules mix very fast due to electron
 sharing
positive/negative charge ions not to mention kinetic friction (maybe thats the
 reason
the Tank gets so warm when filling - gee why don't people think of these things)
Naturally the mason/ant jar is not going to mix due to the density and mass per
 volume
of the jar is far to great and ant bodies have for static friction than atoms.
 However the
belief that rolling a tank vigorously will mix the gases then I might assume
 someone
rolled your head around vigorously and stirred the brain cells contents
 sufficently
to homogenize the mix.

Amen Dave!!!!!!

It is just another case of gross misinformation of ENRICHED AIR diving.
Oh, for the original poster, my instructor is Special Forces retired.  So
the UDT/SEAL statement means nothing to me.  No disrespect to UDT/SEALs; my
father was UDT.  But a statement that UDT wouldn't do it,  therefore it is not
good is idiotic.

        I am a Public Safety Scuba Instructor (I teach members of Dive Rescue
        teams) and if it's any consolation, your instructors had to go through
        the same thing you did.  Instructors in particular HAVE to be the
        strongest and most informed.  I realize it's hard work, but it is
        something to take pride in as well - something that sets you apart
        from the average scuba tourist.  Recreational diving is great, and you
        don't have to be the strongest or smartest for that.  If recreation
        is all your after, you don't need to work that hard.  If your goal
        is to be an example and superior diver (Divemaster) or to teach
        others the skills (Instructor) - you get what you pay for!

Subject:      Tiger sharks in Hawaii

On the news today, it was told that there has been two more Tiger
attacks in the last two days. The last one on a boggie boarder who
lost his leg and was recovered dead. If the story in one of my
scuba mags is right, this makes three this year.
This is a little strange for the islands. They have not had any
shark problems for years. Can some of you marine egg heads who
study this type of occurence help me on this one.

The reason being is that I find it real strange that in a area
where there is good feed available, why would these sharks start
to feed so close to shore. I have been in Hawaii and there are
hundreds of people wading in the water or surfing. Why now is
there a Tiger problem? All of the problems are comming from Tigers.
The young woman taken in December was in murky water and she swam
there every day. This is understandable. However, now people who
are not there every day and are moving rather fast, as in a boogie
board are now under threat.

My reason for asking is in the realm of :

Has the weather changed the feed in the waters?
Has the pop of Tigers increased?
Has fishing by the world nations changed the area in which
    large sharks are to be found?

The authorities have already taken three Tigars and are
    hunting a larger one as we speak.

Just so I am not misunderstood, I can understand a few sharks in the
water and the sighting of them. These problems this year in Hawaii are
a little different. Something has changed in the environment there.
Do we have any one out there doing their Masters or PHD in this
type of area?

Subject:      New Co-Listowner for SCUBA-L Needed

Howdee SCUBA-L Folk:

I'm presently the owner of SCUBA-L. However, in the past 6 months
or so my workload has increased to a degree that I simply don't
have enough time to administer to the list. As a result, many
of the requests that are posted to the list to be deleted, or
mail that bounces from deleted accounts are either missed, or
not taken care of for several weeks. This is, no doubt, extremely
troublesome for those people that are trying to change their
settings on the list and are unable to.

So, I'm asking for someone's to volunteer to become a co-listowner.
The co-listowner would, basically, take care of the day-to-day
administrative needs of SCUBA-L. Since the list is based at
Brown, I would remain co-listowner, and if anything happened
to the LISTSERV that SCUBA-L is running from, etc., I would take care
of it. I'd also have no problem assisting the new co-listowner
in any mail problems they couldn't resolve, etc.

Please send e-mail to cyang@brownvm.brown.edu if you are interested.
The administration needed should only take up a few minutes a day.

Also another observance of new equipement sold is to divemasters and instructors
of a store (majority which is sold at keyman price) so new students will usually
 have
exposure to top of the line which is always more expensive to bring a profit
to those stores.

I own and use a Genesis regularly (all the way from OW to Divemaster).
It has worked fine, but if I had to do it over again, I'd buy a
U.S. Divers Cousteau.  The Cousteau has a really nice internal harness
arrangement that makes hovering easier and appears to generally make the
jacket ride more stably on your body.  The instructors I worked with
when I did the Divemaster work all used them and swore by them above any
other jacket available - this is high praise considering that they can
use anything they want, more-or-less for free.

Subject:      Shipwreck Festival announcement

  I just received a circular from the Ford Seahorses Scuba Diving Club
announcing the 1993 Great Lakes Shipwreck Festival, to be held on Saturday,
February 20, 1993 in Dearborn, Michigan.  (The club is made up of employees of
Ford Motor Company, for those curious about the name)  It says that the next
show is coming, and to order tickets soon, if you're interested.  I went last
year, and had a good time.  This group puts on a decent show, and do
especially well with their seminars on special topics, in my opinion.

  Speaking of seminars, there are two this year.  The morning seminar is
titled "Deep Diving Controversy:  Real Answers to Practical Questions".  It is
offered by Bret Gilliam, a professional diver with over 12,000 dives logged
since 1958.  The afternoon seminar is called "What Is This NITROX Stuff?", and
is offered by Larry Taylor, Ph.D, a biochemist at the University of Michigan
School of Medicine.

  This year's brochure does not mention what films or video will be shown for
the day or evening films, as has been done in the past.  However, it does say
that the main film festival will be shown twice, at 3 pm and 7:30 pm, so I
assume that the omission was due to lack of room on the one page mailer.
They also promise "dozens of shipwreck artifact displays and historical
exhibits", and that the show will be "Exclusively Great Lakes oriented".

  Tickets are $13 for the exhibits and films if ordered before Feb. 6, and $18
after.  The seminars cost $15 for the deep diving presentation in the morning,
and $12 for the afternoon presentation on nitrox.  There is also something
called the DAN O2 course, which costs $55 for DAN members, and $85 for
non-members.  The non-member price includes a 1-year DAN membership.  Nothing
in the brochure explains what this course is, however.

  Mail your ticket orders to GLSF, PO Box 3858, Ann Arbor, MI  48106.  Checks
should be made out to Ford Seahorses Scuba Diving Club.  I recommend you mail
the order quickly, as the seating is limited at both the film show and in the
seminars.  In the previous years, the show has been sold out months in
advance.
