For an Undersea Environment, there is the Pressure, the Darkness, and the Cold

from http://www.southernfriedscience.com/bioshock-oceanographic-how-deep-is-rapture/
"Based on its geologic setting, the limitations of human engineering, and the marine species found swimming and crawling around the city, the base of Rapture is no more than 150 meters from the water's surface."
( I gave it about 200 Meters )

Why MY 600 foot Depth For Rapture ? :
I watched the games initial Descent of 10 .. 18 fathoms, then the window was covered, I kept counting time and then you emerge near the seabed on a ridge where you look across/down on the Cityscape ( and the elapsed time made it something like 400 feet down ). From there you mostly move sideways and go by some buildings, descending a little more, and finally enter up on the side of the Rapture Transit Authority building, with its numerous floors below that spot ( and a seabed some indistinct distance below ).
A 600 foot depth is far enough down to be completely dark - without any sunlight ever reaching it. Deep enough to have tall buildings, which at their top, still are some ways below the Ocean's surface ( one iceberg, too close, would tear the tops off skyscrapers any higher (surface-scrapers ?) - Even with the Mount Ryan (volcano) blocking progress of most icebergs ). The Lighthouse is perched at a shallow spot on the top of the Sea Mount (undersea mountain/volcano) - which gives us my possible/likely 600 foot depth for Rapture's buildings - instead of the 2000+ foot depth of the seafloor of Rapture's given location in the North Atlantic Ocean ( see Ocean depth Maps#Depths West of Iceland ).
Being too much deeper and it becomes horrendously impractical engineering-wise ( ie- "Six miles under the Sea" - muttered by a deranged Splicer/Atlas, isn't any great evidence for the actual depth, and there are actually VERY few spots in the Ocean THAT deep ). Such a greater depth also has incredible water pressure -- which would require Star Trek Sci-Fi or bad Magic Fantasy. Having thick reinforced concrete, and the Novel's Ryanium windows a foot thick, good pressure seals, and workable submarines -- IT is all problematic enough at just 600 feet.
Rapture's Buildings have to not only support their own weight, but also the weight of the water pressure at that depth.

Fathom : A Fathom Equals 6 Feet :
So my 'typical' depth for the lower 'street' levels of Rapture are at 100 fathoms
There probably will be some 'club' in Rapture called the "100 Fathom Club" (yes very original)
"20000 Fathoms Under The Sea" wasn't how Deep, but how Far ... 120,000 ft = 22 miles ( not actually very far, but likely further than a 'Bathysphere' could go on one battery charge )
"Your New Life AT One Hundred Fathoms" ( introductory book given to new immigrants )

No Doubt There Would Be Undersea Euphemisms :
Slang Fun For Rapture :
Flush THAT Out into the Sea ( dismissing someone's statement/idea )
Fontaine Fishfood - Referencing the people it was discovered Fontaine murdered.
Suckered Like a Squid - to be ripped off ( someone wasn't 'Buyer Beware' enough ... )
Can't Drink the Sea ??? These don't all have to make sense if Splicers are heard saying it.
20000 League This Sucka !!! - "Up Your Ass With A Bunch of Glass""Welcome Back Kotter", season five
Cat Or Fish, but NOT Catfish - Some comment/slogan about the quality of the catfish grown in some Rapture fish farms
Hey Charles, Not Today - a 'blow off' of someone ( alluding to elitist-type pretenses - like someone 'Cutting in Line' ).

Shearing the tops off buildings if they were too close to the ocean surface - THAT would be a 'bad thing'. Look how many hundreds of feet deep the ice extends under this only moderately sized iceberg.

Birds have big lungs ? Some Airspace within the Suit ? INSTANTLY COMPRESSED.
Explosive Shock Wave traveling thru the body - pulping capillaries - Instant "Songbird Pate"
Songbird is hardly explained and quite magical (Fantasy).
Magical Tear Portals ( We saw 'reaching thru Tear' in the Selling Baby Anna scene - All So Vague. )
