Did a nice 77-minute dive at Day Island Wall with Pete Gelbman last night. Man, it was crowded down there with at least 30 divers in the water. But there was little current, the vis was decent, and there was lots to see ... spotted 11 wolfies, 3 octos, and 3 dogfish along with all the other usual suspects.
Here's a photo show from the dive ...

Nice pics, and a great tally on wolfies, octos and dogfish . . .Grateful Diver wrote:Did a nice 77-minute dive at Day Island Wall with Pete Gelbman last night.

Wish I could have joined you. Work had me there late, filing two different briefs . . . someone make it stop, please.
(As always!)
Yeah - 77 minutes, and he was probably on a LP95! 
Great pictures Bob! How big were those octos? 10-15lbs?

I was on a 119 ... used about 92 cubic feet of gas for the dive.Sounder wrote:Yeah - 77 minutes, and he was probably on a LP95!

OK ... so here's a quick quiz for those of you who were at the Gas Management seminar ... 92 CF of gas, 77 minutes, average depth of 54 fsw.
What's the RMV (surface consumption rate in cubic feet/minute)?

PS - Those octos were pretty small. The biggest one was maybe the size of a grapefruit.

Indeed it is. For reference, dig up the video of the Six Gill Bob posted on the Six Gill sightings sticky over on northwestdiver. The slow, almost silent breaths are Bob's. The "omigod, that is a big freakin' shark" breaths are mine . . .aquanautchuck wrote:Bob: You sure you were even breathing??That like a breath every 15 seconds.
I used 90 cubic feet of gas on that dive, Bob used something like 60 or so.
If you look carefully behind that guy's ears, I swear there have to be gills there.

A great day on the wall....
Lee, Kirk, Richard and I arrived at about 7pm. Lee and I buddied up and decided to go south along the wall. We were lucky enough that when we hit about 70', we saw a couple of small octos fighting on the bottom, and low and behold, in a small cavern above the wrestlers, was a big GPO. Is is mating season about now??? She looked great and we sat and watched the little guys tussle and eventually, one went into the cavern with her. Could this be romance??? Hope he did not become dinner. Lee and myself continued on and saw another octo in the open. After 90', we turned the dive and started the ascent. It sure is fun ascending a wall. I love that feel of flying. Did short deco stops every 10 feet and at about 50' on a ledge we found a sailfin sculpin. My first. Got a couple of good shots, but the little guy would not sit still for anything. Met up with our other dive team and and did our 3 minute saftey stop and 20'. Popped up about 10' feet away from our entry point. A fun dive. Max depth was 90' and total bottom time was 56 minutes. Thank you Lee and the critters of Puget Sound..

It's ALL good in the world today ......
Exactly what I got. My RMV actually dipped below 0.7 recently, people say it happens around 50 dives or so, and I'm approaching that, so I hope it keeps dropping.lamont wrote:I got .45:dsteding wrote:Answer (and not to ruin it for others):
About 0.25-0.35 cu feet/min less than what my RMV is.
54 / 33 + 1 = 2.63636 ATA
92 cu ft / ( 77 min * 2.53636 ATA ) = .45320 cu ft / min / ata
(which is about equal to my personal best ever)
heh, I missed the "less than what my RMV is" part -- remedial reading comprehension 101 for me...dsteding wrote:Exactly what I got.

Yeah, I was hiding the ball on the actual answer. What is amazing is that Bob's RMV is almost half of what mine is. I guess that means I should always dive doubles with him . . . which is the next project.lamont wrote:heh, I missed the "less than what my RMV is" part -- remedial reading comprehension 101 for me...dsteding wrote:Exactly what I got.

But my bottom time is more than 30 times what yours is ... at the rate you're improving, you'll probably be using less gas than me in a year or two ...dsteding wrote:Yeah, I was hiding the ball on the actual answer.

Actually, where I think I have a higher RMV is at the beginning of the dive-it may be inflating the wing and suit initially, but I find that I'm still focussing on trim and buoyancy in the first 10 minutes of the dive before getting settled in. Because of that, I focus less on nice, even, deep, slow breaths, and blow through air in that part of the dive. Second half of the dive--and even accounting for depth--I find I use less air. So, to get my RMV down, my goal is to just remember to breath slow, deep, and even from the get-go.
Okay, hijack over, these pictures are really amazing . . .

After awhile you just settle down and you're basically good right from the start... Its not something that you can really practice very effectively you just get more experience...
