View Full Version : Charlie can't go back the way he came to the Looking Glass
novagator 05-17-2007, 08:35 AM Charlie is stuck in the station because if he tries to leave the station after being there longer than 20 minutes, he will get the bends on the way up.
The station with the moon pool has a compressed atmosphere to the depth of the station (I would say 60 to 80 feet down). Now dive tables limit yourself there because of the nitrogen building up in your system. Charlie and the others in the station need to decompress before coming out because of the moon pool and the air pressure being the same as the water pressure.
for those that saw movie the abyss know what I mean.

Maybe you should email that info to TPTB so they don't make that mistake and these forums don't become inundated with people crying foul! :rolleyes:
RodimusBen 05-17-2007, 09:03 AM Yeah don't get your hopes up that they are going to take all that into account.
novagator 05-17-2007, 09:09 AM I figured they wouldn't and would screw that up. Just wanted to point it out.

I don't think it is that deep. But it is probably deep enough so that if he spends a long, long period of time down there, he's going to have to deal with decompression.
lostgurl 05-17-2007, 09:23 AM It didn't seem quite that deep to me either, but who knows. Wouldn't you use equipment to decompress on the ascend, or at the end of the dive in a chamber? I don't think doing it before you ascend would do much good since you still have to ascend, your body would go through pressure changes on the way up.
DemonPreyer 05-17-2007, 09:35 AM With all that equipment down there I'm sure they have either an oxygen tank (scuba gear, etc.) for ascension or some "other" (to make a bad pun) way of coming up. We just don't know yet, but probably won't find out til S4!
MtnGrlbytheBay 05-17-2007, 10:04 AM I don't think it was that deep either, but I did happen to wonder if his ears were popping. I mean, even in a 12 ft pool, you'll feel pressure at the bottom.
very-lost 05-17-2007, 10:27 AM I'm not a diver, but it didn't look all that deep ... maybe 40 - 50 feet.
It would be a problem if they keep the atmosphere in the LG mixed different,m but I don
t think they would.
It looked like Charlie came up in the pen for the submarine. If the sub docked therre and then went to the surface, then they would need to constantly changfe the air mix in the sub depending on which direction they were going. :undecide:
Mondoz 05-17-2007, 10:33 AM If you look on the schematic of the station, there's a scale on the side that shows the ocean floor at 80m deep, and the floor of the station at 70m... :eek:
I don't think we're going anywhere near realism here...
mikey_mike 05-17-2007, 10:35 AM in next weeks epi it "seems" that Mikhail and Des confront one another in the looking glass
Now it might be edited to "look" like that but if that IS the case then clearly Mikhail and/or others are able to routinely make that trip
I imagine that whatever would be needed to deal with those kind of pressure changes are available in the looking glass.

No. I expect the moon pool will be in an airtight room with airlocks between the moon pool room and the rest of the station.
That way, the rest of the station will be at normal air pressure. The only place which will have high pressure will be the moon pool room which the occupants will only enter for short periods of time as they're entering/exiting the station.
Milgram Experiment 05-17-2007, 06:09 PM Why are people so eager to jump at the writers' throats? Jeez, how jaded and arrogant can you be....

In 'The Abyss' the platform was a deep sea drilling installation.
The 'Looking Glass' is close enough to the surface that a diver without even scuba gear can make it down there.....
It's probably deep enough that if he stays there a long time there's some risk of 'the bends' but it's not guaranteed that he'd die.
Pythagoras99 05-17-2007, 06:20 PM No. I expect the moon pool will be in an airtight room with airlocks between the moon pool room and the rest of the station.

It didn't seem that way. They came bursting in as soon as he started making noise in there, like they were just hanging out on the other side of that door. There wasn't any time for pressurization. (Not sure if the writers would be going for that degree of realism anyway, though.)
richlost 05-17-2007, 06:22 PM According to this screencap
http://gallery.lost-media.com/displayimage.php?pid=99006&fullsize=1
the entrance to the Moon Pool is at 70 metres depth thats 229 feet deep.
Good luck getting down there, let alone trying to get back up.
According to sources http://www.pbs.org/saf/1102/teaching/teaching.htm second paragraph, for every 10 meters depth, it's equal to one earth atmosphere, so 70 meters would be surface pressure (14.7 psi) plus 7 atmospheres = 8 atmospheres. That would be117.6 pounds per square inch of pressure over every inch if his body.
polusmaximus 05-17-2007, 06:23 PM it didnt look that deep. you could see it from the surface
Pythagoras99 05-17-2007, 06:35 PM The station looks to be about 50 feet down. The ascent rate for decompression is about 40-50 feet per minute. So as long as he doesn't come up faster than that, he should be okay. Right? However, does decompression work just as well holding your breath, or do you need to be actually breathing to help move the excess gasses out of your blood? And how bad would it actually be to come up from an extended stay at 50 feet without decompressing? Are there any divers here who know the answers to those questions?
BoulderGeek 05-17-2007, 06:43 PM Perhaps the schematic should have been noted to indicate 70 feet. That seems more plausible, though you'd still need lots of weight to get yourself down that far.
According to NAUI dive tables, (http://orgs.bloomu.edu/scuba/divetables/divetables.html)you'd exceed your non-decompression free dive parameters at 45 minutes. After that, you'd need at least a 5 minute decompression stop at 10 feet (~3 meters) before being safe to ascend.
More bottom time = more decompression time.
Better not dally down there, Charlie.
BobLoblaw 05-17-2007, 06:44 PM If you're breathing normal air mixture, spending a number of hours even at 50 - 100 feet will require decompression stops. If you surface without them, you will most liekly get bent.
Recreational divers are supposed to limit their depth to 130 feet, since most dives below that depth require decompression stops.
Now, maybe the air mixture in the Looking Glass is not the normal mix and they could have additional time? I don't have any dive tables laying around, otherwise I could give you some specific times for depth..
HatchLatch 05-17-2007, 06:46 PM Tide?
Remember that there also seemed to be a chart that correlated to high and low tides on the station schematics. Maybe they lucked out and got there at low tide. Because of the magnetic anomalies of the place, the tide level may vary dramatically.

An open portal like the Moon Pool would require a constant presssure equal to the water pressure outside the portal. The structure of the Looking Glass would fatigue and fail from the constant changes in pressure required to maintain the Moon Pool, if the tides were as drasctic as you suggest.
tomtalkin 05-17-2007, 08:04 PM The island has apparently cured people from gunshots, paralysis, sterility & a number of other medical issues(besides crushed legs). Do you really think it couldn't cure someone from the bends?
The Looking Glass station also didn't appear to be very deep as it was clearly very visible as soon as CHarlie broke the water's surface.
