A winter break seems to short of a time span to get a good DM course. I suppose it could all be squeezed in, but in my experience DM courses are more internship than anything else. They tend to last months, not weeks.

Dunno. I work with everything but animals. I think the meaning was layers of cells. Cells (with a few weird bacterial exceptions) have just a single membrane around the outside. (Though some internal structures have two.) Bored yet? I could go on....

Next I think you meant cell layers. Last I heard, animals don't have cell walls. Critters I work with do! :wink:

Pietsch and Orr have a three volume set called "Fishes of the Salish Sea" that all the cool fisheries biology folks like. If that's too much for you, my fishery friends recommend Coastal Fishes of the Pacific Northwest by Lamb and Edgell. For no good reason I have both on a shelf at work...

Couple thoughts: 1. There's more than one way to get gas into the arterial system. However, the way you're thinking of is due to lung overexpansion injury which ---wait for it--- involves overexpansion of the lungs. 2. Don't even think of doing the experiment from 20 m up holding your...

Interesting. Redondo worries me far more than the Alki Coves. But I hear you: It's the sketchy folks cruising by eyeing cars and such that worry me. The only thing I've ever had stolen at the Coves was a pair of ankle weights, and I'm pretty sure another diver unrelated to our group grabbed...

Cool. What part of town are you in or will you be in? For clubs unaffiliated with shops in Seattle proper, Marker Buoy is a good option. There's also some great folks up north a bit (Edmonds/Lynnwood etc) but I'd need to find names as they escape me now.

Bare used to (and as far as I know still does) offer a dizzying array of size combinations to fit a lot of body sizes with a "stock" suit.

Lots of dive shops have regular shop dives. Underwater Sports alone has 5-6 satellite shops and they generally each run a shop dive once a month. Marker Buoy is Seattle's oldest dive club. A good question to ask is do you just want to dive, or do you want to meet socially when not diving...

Edited: Question deleted because answered while I was typing....

That'd be the Bitter Lake (Aurora Ave. N.) Home Depot? I often kill time there as well. (Or do all dive shops have Home Depots near by? I'm genuinely curious.)

It depends. Tanks are re-filled immediately after diving so they're ready for the next day. We often will top them off the next day.

You've gotten good advice here. Let me reiterate a few things and add a couple: 1. Drop it off one day, pick it up later. 2. Find a shop that will overfill slightly so when it cools it's at pressure. (My LDS does this routinely. They know how much to "overfill" any cylinder to it's at...

Welcome! Sorry I missed your initial arrival. Great name, by the way. -Another Tim

To answer your question, not so much. My female dive buddies have been trained for the situation we're diving in. If touching is required in that scenario, they are already aware of how it's going to go down and shouldn't be too surprised. (I do go over a few things if it's a new buddy, male...

I usually see a 6 pound difference going from a steel to aluminum, but that may be the details of my steel tank (HP 120)

I love this idea on principle, but I wonder about situations where touching is expected? At least equipment touching (e.g., shared-air exercises and tired-diver tows). Less applicable to OW, but you can't get around touching in Rescue. You can give the option to opt out, but then they're...

I know my instructor training included a discussion of this. I also know instructors who were "fired" for such inappropriate actions, though I don't know if the agency revoked their credentials. For my part, I tend not so much to ask permission as to tell them "here's what I'm going to be...

Speaking strictly from the scientific diving perspective in the USA , AAUS Is the key. It doesn't matter where you got the tech certs, as long as you have them. I focus on undergraduate education and my divers on research projects are these undergrads. Since getting an undergrad who is tech...

A question of personal interest from a local: When folks dive with a sidescan sonar company, are they following OSHA rules? I work in academic diving, where it's AAUS. I've heard OSHA rules are a pain to work with.
