While Dianna is recovering, I'm leaving her videos running 24/7 in the background so her channel gets more views. The algorithm is hungry for this attention, so I feed it to support her.

[@randint]

I appreciate your effort to get her videos more views, but KZbin probably has taken some measures to stop counting repeated views of a video from the same device. Therefore, if you watch a video over and over again, say 20 times, it would probably only count as five or six views. Even if you watch all her videos on the channel one by one, it'd probably not be much better since KZbin can detect that you are trying to farm views. A much better option would be to like all her videos.

Some of you caught the drone at 18:25 was stuck suspiciously close to us. That's true, usually DJI drones can fly miles away from the operator. Here's what happened: The drone was originally paired with Levi's phone. But in the extreme cold, Levi's (older) phone battery died within minutes - an Arctic weather issue we hadn't considered. So we weren't able to use the drone at all. Fortunately, I had downloaded the DJI app on my phone. Unfortunately, we didn't think to log in before leaving Alaska. (There's no wifi on arctic sea ice, it turns out). Flying without logging in meant the drone was limited to 50m horizontal, and 30m vertical. Wah wah. Also, we’re still working on the videos about how the submarine navigates and communicates with the outside world as well as what it was like living on board if y’all have any questions!

Or even just pumping bilges when you have an 'angle on the boat'. Lots of little things like that, but then we had a great comradery. Like forming a 'trim party' for the new dive officer. Or earning your 'blue nose' certificate when you went 'up north'. Don't want to go back, but glad I did it.

@@sittingturtleduck I assume something to do with oxygen generation

[@extrastuff9463]

@ Probably a bit more too, removing CO2 is pretty important even when there's enough oxygen left to breathe. I could see locally stale air being an issue too in a submarine with various rooms and narrow corridors/closed doors between them without any kind of draft from outside air. So probably a mixture of forced ventilation and various measuring points along the boat. And I'm sure there are other byproduct gases of humans living in an enclosed area for too long one might want to take care of on top of that. I'm tempted to look up that series Destin (smartereveryday channel) did again to see if it has any specifics for whatever submarine class he was in.

@@extrastuff9463 yeah Destin has one whole video on it from the submarine series

​@@sittingturtleduck I have no idea, at the time that's all he would say. When I would ask him for specifics about his work, he would just laugh and say, "that information is only shared on a need-to-know basis, and unfortunately, according to the US Navy, you don't need to know." Heh. He was a big ol' soft-spoken nerd, so imagine Mr. Rogers saying that and you'll get an idea of the tone he used with me as a kid. All I know is that he was first designing electrical stuff for life support systems for various deep sea craft (one of his early projects was working on a deep sea craft with Jacques Cousteau, who had some kind of brief partnership with the US Navy on developing the tech, from what I understand) and then after many years of working in ocean engineering and getting successive security clearances eventually was in charge of a team that designed/developed systems to keep people alive in nuclear subs when they were submerged. I always assumed it had to do with making sure people could breathe, so that's all I got! The other comments talking about supplying oxygen and removing CO2 are probably correct.

I served on both a 637 class and a 688 class submarine during the height of the cold war (70's and early 80's). Crossed the Artic Circle but never under the ice. I do remember when we were at periscope depth up north and ran through a temperature inversion and popping to the surface. We had to flood hard to get us back down, but once we got out of the inversion we sank pretty fast and the trim pump could not keep up with the depth change. The Officer of the Deck considered blowing the ballast tanks but changed his mind and ran up a couple of knots of speed instead. Submarine life is 99% boring interrupted by shear terror.

Brings back some memories. I have done more than one Ice-X on a submarine. It is indeed serious business. We started doing these in the late 70s and early 80s as the Soviet Union started to use the Arctic more and more as their private lake. This is where they like to hide some of their ballistic missile submarines and wherever you find a Soviet or Russian missile sub you are going to find an American fast attack submarine to make sure it will not be able to launch its deadly payload. The Soviets designed the Typhoon class of ballistic missile submarine specifically to remain motionless under ice thin enough for them to blow their ballast tanks break through the ice and then launch their missiles. That is why it is so big with specific design features to enable them to break through the ice and clear their missile tubes for launch. It was never a "Cold War" for submariners and the war to protect the United States from unimaginable destruction is still ongoing. The silent service never wants publicity or thanks. Just knowing what they do is vital to our survival as a nation has always been enough.

The sonar sphere extends past the forward main ballast tanks to allow clear sound transmission though.

Just a minor correction for you. The main ballast tanks don't run the entire length of the ship, they are only in the forward and aft part of the ship. Also, variable ballast is not pushed around the ship using compressed air. A large pump moves water from tank to tank and tank to sea in the variable ballast system. Compressed air is used to rapidly push water out of the main ballast tanks during emergency situations to get the boat to the surface quickly. During a regular surfacing operation, air is blown into the main ballast tanks using a blower.

It depends on submarine design: some have only forward and aft tanks, but most have centrally located main ballast tanks, with forward and aft trim tanks. 600 psi compressed air is used to surface the boat by driving water out of the ballast tanks. This is standard practice, not just in emergencies. Once on the surface, a 10psi blower system pushes outside air into the tanks to finish the job and conserve compressed air. The blower system cannot be used while submerged, of course, as there is no source of air.

[@mrt1r]

@@paulmaxwell8851 To clarify, specifically the class of Submarine she was on works the way I mentioned. You are correct though that some configurations use HP air as a standard method for deballasting the MBTs.

[@fasfan]

@@paulmaxwell8851 not sure where you get the "most have" info from. All submarines in the US have forward and aft main ballast tanks and trim tanks throughout. I believe old WWII fleet boats had ballast tanks along the sides of the hull. So I would say most boats (at leslast in the US) have forward and aft main ballast tanks.

[@daveschlom4033]

So glad to see you healthy and creating. Love to you and yours Diana.

[@DavidVerch]

I'm not sure I would call the change in hull shape significant when the sub is at depth. It certainly does change shape. We had a system where we had to clean out the heat exchangers when we were underway. We did this by removing a spool piece that was maybe 2 feet long. The flanges were sealed by an o-ring. When we were on the surface the spool pieces could be installed easy peasy. Important point the heat exchanger was installed cross wise in the hull. When we were at depth the pipes moved such that you could still put the spool piece in but the clearance was so small that it would cut the o-ring. We used chain falls and all sorts of stuff to try to get that piece in without cutting the o-ring.

With a moving home position you can set the home position of the drone to the radio controller (operator) and not the GPS position of take off. Rookie mistake.

Great work on this deep dive (of your deep dive), Di! Awesome that, even in the Arctic, GPS is accurate enough to detect ice sheet movement within an hour. Can't imagine how bizzare a 14-degree tilt was surrounded by water colder than the Titanic sank in, but seems you had a *ball as t*-ypical and rolled with it! Would be interesting to see that sub crew sit down with some astronauts to compare their experiences, since a submarine is kind of the opposite of a space station.

Feel your pain about (almost) losing your footage in the harsh environment. CNN, Nat Geo and I went in the drink (briefly) during SCICEX '99 (USS HAWKBILL).

[@Andrew-wv7qp]

When you listen to the crew talk about buoyancy as weight, it drives home a fundamental fact; mass and weight are related but not the same. Mass is the amount of matter in something, weight is the net effect of gravity on said thing. So, the submarine, in dealing with the varying buoyancy conditions, was altering its mass to keep its weight constant.
