My wife bless her heart cracked me and my daughter up last night. We were watching some lame “b” movie flick with ICE T in it called “Final Voyage”. Anyway an old luxury liner sinks at the end of movie like the Titanic did you know one end up sinking down and she remarks, “boy that must be some deep water.”
Anyway it spawned this question how deep is the deepest part of the ocean. And now for my dumb question is the water any warmer that deep depth?
Oh one more anybody know how long a luxury liner is say like the Titanic?
depression in the Pacific Ocean, 210 mi (338 km) SW of Guam. The deepest (36,198 ft/11,033 m) part of any ocean, it was reached (1960) by two men in a U.S. navy bathyscape.

The hull weighed 26,000 tons
The ship weighed 46,328 Gross Registered Tons. Each ton equal 100 cubic feet
She was 882’ 9" long and 92.5" in the beam.
Each funnel was large enough to drive two trains through.(right)
There were nine decks and
It was as high as an eleven story building.
I don’t know for sure about the temperature, but I would think that the deeper water would be colder because cooler water tends to be denser. You can observe this phenomenon swimming in a lake, and I suppose the ocean would be similar. There is one notable exception, and that is the presence of fissures in the ocean floor from which molten rock occasionally spews. The water near those fissures would be quite hot! But these fissures are only found in certain areas.
Couldn’t locate the temperature, but I believe it’s an active fault, so it should have steam vents along the crack.
If you’re wondering about writing rescue scenarios, ala The Poseiden Adventure, here’s more data.
1 x 10^{5} N m^{-2} Typical atmospheric pressure
1.5 x 10^{6} N m^{-2} High pressure bicycle tire
2 x 10^{7} N m^{-2} Typical scuba tank pressure
9 x 10^{7} N m^{-2} Peak pressure of a fist on concrete during a karate
strike
1.1 x 10^{8} N m^{-2} Pressure at the bottom of the Marianas trench
6 x 10^{9} N m^{-2} Pressure needed for the natural crystalization of
diamonds
According to Britannica.com the temperature of the ocean is roughly constant at any depth below the 2,000 meters (6,600 ft) level. This averages around 3.5 C or 38.3 F.
“The density of ocean water varies. It becomes more dense as it becomes colder, right down to its freezing point of -1.9 degrees C. (This is unlike fresh water, which is most dense at 4 degrees C, well above its freezing point.)”
I ask this because my first instinct was the Marianas Trench. But as I was reading this thread some of the ‘remotest places on Earth’ threads came bubbling up to the surface of my memory. IIRC, there is a lot of ocean floor that is not mapped (at least not on maps available to the public). Or am I wrong, and if I plugged in ‘Kermadec Subduction Zone’ into Mapquest I’ll get set of directions? Or have oceanographers developed relatively low resolution maps of all of the ocean floors and though they can’t account for every peak and valley, don’t see anything that could compare to the Trench?
And by the way, does anyone know what caused the Trench? An extension fault? Monsters? Thanks.
As an avid scuba diver I’ve alwayd been amazed at how going down under water seems further than travelling horizontally. I can swim 150 feet without a breath and seems no big deal at all but 150 feet under water seems one helluva long way (my deepest dive ever was 110 feet).
To get a feel for this think of the ore carrier the Edmund Fitzgerald which sunk in Lake Superior in 1975. The ship was 729 feet long and sunk in 550 feet of water. It was speculated at some point that the ship may have nosed under water and had its bow smash into the bottom of the lake. At this point 179 feet of the hull would have been sticking out of the water (about a 15 story building sticking out of the water). The impact cracked the spine of the ship, it broke into two pieces and promptly sunk.
Since then I’ve heard that the ship probably broke in two on the surface from wave action but it still illustrates the depth of water we are speaking of and just how long these ships are.
I have been wondering about this? Pretty much you should be able to find and answer to anything on the internet right? So what is considered a good GQ question and when is something not?
Also I do try(looking up sites) but my internet service is sooo slow loading sites and you people here are soooo knowledgable.
I read a really good book, I believe it was called MEG about megalodons (sp?) surviving extinction by living in superheated water (caused by thermal vents) trapped (by the cold water) at the bottom of the Marianas Trench.
It’s not very cerebral, but it was very good and sounded almost plausible. (Well, only if you disregard the MEG escaping and wreaking havoc around the world.)
Here it is at Amazon:
There are reasonably detailed global-scale maps of the ocean floor available to the general public, as well as more precise maps of “non-sensitive” areas (the Navy has released some data in recent years), so we know for sure that there aren’t any features comparable to the Marianas Trench in depth. You can bet your bippy, though, that highly detailed maps of the seafloor in potentially sensitive areas (like the Norwegian Sea) are in the hands of the military only.
BTW, the Marianas Trench is a subduction zone that marks where the Pacific Plate is going down under the Philippine Sea Plate.
