I've just added some more content to explain how the whole pH and temperature issues is connected, how it varies over the depth, what "surface" means in this context, how it's related to stratification and so forth. I am not an expert though and have no professional background in this. I've been discussing this article with Tim Jickells and he's been helpful with suggesting suitable text and sentences (with reference to his textbook and other textbooks and publications). If you have additional ideas or suggestions for making this clearer and more succinct or for adding more accessible sources (not behind a paywall), I am all ears. I think pH is important to explain here (because of ocean acidification) but I am also mindful of not making the pH section too long in this kind of overview article. Perhaps what I have added could be condensed a bit. EMsmile ( talk) 09:47, 9 May 2023 (UTC)
Quite suprising I only realized now that the lesser oceans have infoboxes, but not the Ocean it self. So here I will put together based on the Atlantic Ocean infobox the appropriate data.

Hello, I am currently editing this article to improve its readability. My work is part of a project focusing on improving the readability of climate change articles on Wikipedia. To learn more about the project, visit: Wikipedia:Meetup/SDGs/Communication of environment SDGs. Bradextw ( talk) 12:13, 12 May 2023 (UTC)
I just edited a little in the second half of the second paragraph of the introduction, which I felt read unevenly. One additional thing I would like to rephrase is the "1% of the surface light depth" thing. However, I am not exactly sure what it means, which is why I think it should be clarified or rewritten.
Just reading what is says, my best guess is 1% of the total depth that light reaches. However, it continues to state that "1% of the surface light depth" is about 200m in the ocean. Now by my guess, that would mean that light reaches (200 * 100)m = 20000m, and there simply is not that much ocean. What seems more likely is that it is the depth at which only one 1% of light remains, which really is not obvious from the statement itself. So yeah.. could someone who knows clarify what it's supposed to mean? Ribidag ( talk) 12:25, 2 June 2023 (UTC)
The [[photic zone]] starts at the surface and is defined to be "the depth at which light intensity is only 1% of the surface value". Your wording was
... is defined to be "the depth at which light intensity is at least 1% of the surface value". Or we drop the quotation marks and write it in a way that is not copyright violation, i.e. paraphrase (?). For it me would sound clearer as
... the depth at which light intensity is still at least 1% of the surface value". EMsmile ( talk) 08:09, 19 June 2023 (UTC)
... the depth at which light intensity is still at least 1% of the surface value"is not actually correct. It is the depth range (i.e. a continuous region of all depths from the surface down to the bottom limit) at which light intensity is still at least 1% of the surface value, The depth at which light intensity is 1% of the surface value is the bottom limit of the photic zone, and is a dynamic 3-dimensionally curved surface. When I edited I didn't notice it was a quote, as it was not very well expressed and needed clarification, and why would we want to use a quote that does not make things clear? The important points are that the natural light level continuously decreases with increase of depth, depends on several variables, and it can fluctuate quite rapidly at times.

I'd like to bring to your attention a proposal by Peter Southwood to have a separate article on density of seawater, see here: /info/en/?search=Talk:Ocean_stratification#Density_of_seawater . This makes me wonder if we need a bit more content on the density of ocean water also here. Density is mentioned 10 times but perhaps it needs its own dedicated section, like we have a section for pH? Or one could argue that it's only a sub-topic at seawater. I am not sure but am leaning towards a new (short) section about density which could then link out to another article where more detail is provided. EMsmile ( talk) 11:28, 18 June 2023 (UTC)
Hi User:Nsae Comp, I think you made the info box overly detailed in the end. It was flagged up to me by the Ref 5 that you used which is flagged as unreliable ( this one). I believe you have added it? I think we should remove these two sections from the info box as they are not that important and just clutter of this info box (if you think they are very important, they could be included in the main text maybe): ++++++++++++ Pole of inaccessibility:

The deepest point of the Ocean though is not the lowest point of the ocean, or of Earth's crust. This would be the Litke Deep in the Arctic Ocean at 6,351.704 km (3,947 mi) from Earth's centre, 5.449 km (3 mi) below sea level, which makes it 14.726 km (9 mi) closer to Earth's centre than the Challenger Deep. [1]The "unreliable" flagging is from this script by Headbomb.

I've removed this recently added content because it's outside of the scope of this article. Perhaps add it to another article. The scope of the article is clearly explained in the very first sentence. Already that section on "extraterrestrial oceans" doesn't really fit but serves to point readers to other interesting content (I wouldn't be opposed to removing the entire "extraterrestrial oceans" and rather put it under See also or in a hatnote.
+++++ Earth's outer core: The Earth's outer core is an ocean inside the planet Earth, composed mostly of liquid iron and nickel. Its depth is about 2,260 km (1,400 mi). It lies above the Earth's solid inner core and below the Earth's semisolid mantle. The outer core ocean begins approximately 2,889 km (1,795 mi) beneath the Earth's surface at the outer core-mantle boundary and ends 5,150 km (3,200 mi) beneath the Earth's surface at the outer core-inner core boundary.

I made a calculation a few years back that the Continental surface area was close to 0.2904 ( 29.04 % ), so the Ocean surface area would be 0.7096 ( 70.96 % ). I suppose it all depends on how deep down the continental slope you go to reference your cut off between Ocean and Land. 70.8 % and 29.2 % is fairly close. 98.245.219.152 ( talk) 01:41, 10 November 2023 (UTC)
