[edit] Landforms
Does this qualify under Category:Landforms or what's the alternative? Alren 18:25, 18 Nov 2004 (UTC)
- Not really. I didn’t see Africa on that list. This is a point in the bottom of a trench (the Mariana Trench). The aforementioned trench is there under oceanic trenches. That list is for things that peninsula, not Florida (e.g. mariana trench) and surely not Miami (e.g. Challenger Deep). Cavebear42 21:46, 18 Nov 2004 (UTC)
- Should a new category be started for "deeps?" I think they are just as important as the peaks of a mountain range such as Everest or Denali. Sowelilitokiemu 19:06, 8 January 2006 (UTC)
[edit] Depth
How could it be that the deep is "10,911 meters (35,797 feet) deep at its maximum", but "Trieste descended to 10,916 meters (35,813 feet) deep in the trench"? 10,916 is more than 10,911.

- Okay, let me try to get to the meat of this. there are 3 articels we should be looking at:
- Bathyscaphe Trieste
- "she reached a record depth of 35,813 feet"
- Mariana Trench
- "The trench has a maximum depth of 35,840 ft"
- "[Trieste] indicated a depth of 37,800 ft, but this was later revised to 35,800 ft"
- Challenger Deep
- "the deepest known point in the oceans, 35,797 feet"
- "Trieste descended to 35,813 feet deep in the trench"
- I think that part of the problem is metric - feet convertions messing people up. Part of it is the dates of the measures. according to Guinness World Records "On January 23, 1960, the US Navy Trieste vessel descended to the bottom of the Pacific Ocean, and on March 24, 1995, the Japanese probe Kaiko recorded a depth of 10,911 m (35,797 ft), the most accurate measurement yet taken.". Ironicly, accoring to this article from the navy, it was deeper than 37,000 feet. (the only article I could find on the navy site.) I was the one that put the data in from guinness and didn't mess with the other data from the sourses. I am open to whomever think that there is a clear way to present this.

- Well, you are right. Still, what is the right depths? As far as I understood, no one knows how deep it is. There is just a assumption about 10923 metres, but nothing for sure, right? Reply to David Latapie
- Let's stay away from meters as that it has never been measured in them. The depth is known and has been measured a few times in differnt methods. weve sent people to the bottom, weve meatured with sonar. im inclined to use guinness as a source and trust its measure (which is well quoted ont he web). Still, we should clean these articles to make them match. Cavebear42 23:46, 22 Nov 2004 (UTC)
- I've modified this article alongwith Bathyscaphe Trieste with the depth measured by Kaiko. Other articles updated are Jacques Piccard, Don Walsh, and January 23. Jay 11:53, 9 Jun 2005 (UTC)
- Thought everyone might be interested to know that JAMSTEC'S own KAIKO page lists the depth it achieved at 10,911.4 meters (or 35,798.6 feet). The 35,840 ft number that was floating around comes from the CIA Factbook (take from it what you will). I agree with Sowelilitokiemu's comment below and also believe that a specific number can't be expected.

How much of the difference in measurements is accuracy and how much is actual change in depth? Nature abhors a vacuum, and I'm sure tons of sediment fall into the trench every year. If the subduction slows, I imagine that the Challenger Deep would fill in quite quickly. Sowelilitokiemu 19:01, 8 January 2006 (UTC)
[edit] Soles and flounders
"They observed small soles and flounders..." I don't suppose this was actually at 10.900 m depth? That's what the article seems to say but I don't know if it is possible. Piet 13:23, 23 January 2006 (UTC)
[edit] Allogromids?
A lot of words that I don't understand, and without explanation. Leptohalysis and Reophax are two more. Maybe some of them can be left out and for others a stub/article can be created? Piet 13:28, 23 January 2006 (UTC)
[edit] Clarification or edit in Fauna section
Over the course of six to nine million years, as the Challenger Deep grew to its present depth, many of the species present in the sediment died out or were unable to adapt to the increasing water pressure and changing environment. The remaining species may have been the ancestors of the Challenger Deep's current denizens.
The sentence in bold seems pretty obvious to me, or perhaps I am reading it incorrectly? The section is describing the unique abundance of soft-shelled organisms in the Challenger Deep compared to other deep-sea survey sites. The last few sentences provide a possible explanation stating basically that the reason is because the current species present adapted to the change. How is this different than evolution in any other corner of the world? That is the premise of evolution, no? The species that adapt to change and survive are able to propagate their lines. The last sentence seems the most (my apologies) "duuh" of all. The current living organisms came from their ancestors... Would anyone think any differently? I mean even to people who believe in "intelligent design" :P
But perhaps I'm missing something obvious, and this section is stating something different? --Acefox 19:50, 9 May 2006 (UTC)
The above sentence also mentions that CHallenger Deep grew to it's present depth over six to nine million years. This is a very short period geologically and it would be a great addition to the article to explain briefly how this happened e.g. are there specific currents that caused erosion of the sea bed, or is it plate tectonics and if so what type of plate movements cause the trench to become deeper?
[edit] Typhoon
Just a quibble. It says that the cables snapped during a typhoon on March 29, 2003, but there wasn't a typhoon then. There was a tropical storm in January, and a supertyphoon in early April, but nothing in March. Are you sure that date is right? Hurricanehink (talk) 02:13, 20 July 2006 (UTC)
