[edit] Depth: slightly less or slightly more than 11 km?
The German Wikipedia has the information that "Marianengraben's" depth is 11.034 m and that 10.912 m was the lowest point reached by human, so this should be examined and corrected in this article. --Romanm 23:57, 8 Jul 2004 (UTC)
Article Challenger Deep indicates 10,911 m (and is said verified by Guinness) and here it is 10,912 m. Wich one is right? [[User:Vrykolaka|Reply to Vrykolaka]] 01:35, 24 Oct 2004 (UTC)

[edit] Pressure ?
Normally, that would be P = ρ g h. Using ρ = 1000 kg/m³, g = 9.80665 m/s² and h = 10,923 m, I get 107.12 MPa (15,536 psi). So why does the article say « 108.6 MPa (15,931 psi) » (which is incorrect anyway since 108.6 MPa = 15751 psi)? Water being ever so slightly compressible means may explain the difference, but it seems a large one...

Seawater has a density higher than 1000 kg/m^3. Salinity varies, but at the surface, it's about 1020-1030 kg/m^3 according to hypertextbook. Working backwards, assuming the depth and pressure measurements are correct, the average density over the depth of the water column would be ~1013 kg/m^3. A minor considering: the atmosphere exerts 1 atm (14.7 psi) of pressure in addition to the weight of the water.

- Ah, that makes sense. Should have thought of that!

[edit] Plural
In French the name is definitely plural; should it be in English too? Aren't the islands the Marianas rather than the Mariana (like the current entry says)? I suggest we look up the Britannica on the one hand, and the UN toponymy committee on the other. Right now I'm off to bed.

- Whatever the islands are called, the oceanic trench seems to be called both "Mariana Trench" and "Marianas Trench". However, "Mariana Trench" seems to be a bit more common based on Google hit counts. Usgs.gov seems to use both: [1] [2], but again "Mariana Trench" is a bit more common. -- Curps 05:51, 23 Mar 2005 (UTC)

- The Britannica is quite clear: both the islands and the trench are singular (they are named after Mariana of Austria). The mproblem I had initially was with the Google method: Google polling is a very poor way of deciding these kinds of things, for several reasons. Internet page counts do not reflect accurately usage in the widest context, because of severe population biases. Google counts also do not discriminate between pages which are semi-automatic copies of each other (several web servers pump content from Wikipedia, for example), and the aforementioned population biases are also reflected in the way errors (as well as corrections and facts) spread from page to page.
- To summarise, an overwhelming Google "vote" in favour of one of several alternatives should be counted only as one corroborating, weak element of proof.

- You are right that Google hit count is only one element to take into consideration, although an important one. Brittanica usage is also only one element to take into consideration. I would have hoped that the scientists who actually study oceanic trenches would have a clear preference, but as usgs.gov usage shows, they are also divided. All in all, though, I think we can leave it at Mariana Trench. -- Curps 20:08, 23 Mar 2005 (UTC)
[edit] Broken image?
The picture seems broken, to me. Does anyone else not see the image? Wadsworth 22:46, 19 April 2006 (UTC)
[edit] The Abyss?
The Movie: The Abyss took place near the Cayman Trench, not the Mariana Trench.
[edit] The Band?
What about the rock band from vancouver, british columbia? anyone feel like at least creating a stub for this talented and catchy group? check out http://www.myspace.com/marianastrench
- not unless they are notable. It is irrelevant here anyway.
