Is it possible to define (2drms)? thanks 151.29.76.84 (talk) 05:53, 5 December 2021 (UTC)[reply]

see Circular error probable

Another question: I feel that

Such a claim will require a survey of all three basins by both echosounders and pressure gauges, such that all depths are measured by one set of equipment and use the same correction calculations.

is somehow contradictory with the above statement that the DSV Limiting Factor has measured all the three deeps. Probably the DSV LF have not claimed this even if they could, but a less doubt-evoking text is welcomed (I know: I see trouble were no other finds them). thanks again 151.29.76.84 (talk) 09:46, 5 December 2021 (UTC)[reply]

The measurements were not made during one dive. Even the best CTD's measurements have to deal with (minor) instrument drift.--Francis Flinch (talk) 14:55, 5 December 2021 (UTC)[reply]

No link to what they are or how they’re made. 2600:1700:6756:4830:9DFB:D817:1B88:C1CD (talk) 23:39, 10 February 2022 (UTC)[reply]

The samples taken were depth soundings. All the information was there in the paragraph about the 1875 Challenger expedition, but it was presented in a slightly confusing order. I have tweaked this to make things a bit more clear. Does that help? Pyrope 02:50, 11 February 2022 (UTC)[reply]

There are a lot of mentions here of bomb soundings or explosive soundings, which are not explained in the article. I would like to link these to another appropriate article, but I don't know what the right target would be. The articles on echo sounding, depth sounding, and multibeam echosounder don't seem to cover this. One thing I found was Sofar bomb but it doesn't seem like the right topic. Can anyone help to find the right article, or do we have a gap here? Orange Suede Sofa (talk) 03:27, 24 June 2023 (UTC)[reply]

I've started a discussion at Talk:Mariana Trench about the inconsistency between the values used in the two articles. Mikenorton (talk) 12:12, 7 May 2024 (UTC)[reply]

The article needs a section at the start saying what it is and how it formed. I find it most odd that there isn't a section about the geological processes that formed it. Just endless willy-waggling accounts of the various expeditions. 86.189.141.23 (talk) 19:53, 11 May 2024 (UTC)[reply]
