[[File:Ocean influence on climate at four example locations.png|thumb|upright=2.5|Air temperatures (degrees C) in [[New York City|New York]], [[San Francisco]], [[Maine]], and the [[French Riviera]] show different influence of the ocean on local climates.]]
Hi [[User:Jturner20]], I've removed the image on the right from the article as it wasn't clear to me how this is relevant (especially putting myself into the shoes of a lay person reader). Also, is this adding more to the US- and Europe-centric nature of Wikipedia? My suggestion is to either improve the caption to make it very clear what this is showing. Or to move this to a relevant sub-article - maybe the one on ocean currents. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 10:38, 31 May 2022 (UTC)

== Needs a bit of content on pH value and alkalinity ==

While looking at [[alkalinity]], in particular the section on "ocean alkalinity" it occurred to me that this article is missing some short content (and links) about pH value and alkalinity. Content could be copied from [[ocean acidification]] for pH value and from [[alkalinity]] for the ocean alkalinity. I am undecided if this would fit better under physical properties or under chemical composition? Maybe it belongs better in the chemical composition section?

== Capitalization of ocean ==

{{User|EMsmile}} changed in a recent edit some capitalization of "the ocean" that I had added. I am ok about the change, but a discussion is worth it in my opinion. I think I used the capitalized version because I had the  Moon in my head and the change into capitalization there. But that case is somewhat different, since we know many moons and dont speak (yet) of other extraterrestrial oceans. That said, maybe it is worthwhile to underline the difference between the particular oceans of Earth and particularly the world-spaning nature of it. [[User:Nsae Comp|Nsae Comp]] ([[User talk:Nsae Comp|talk]]) 10:07, 30 August 2022 (UTC)
: Hi [[User:Nsae Comp]]: I am not sure about this. For me it's just ''ocean'' with a small "o" all the time, except for names like "Antarctic Southern Ocean". Not sure where else you would want to capitalise the word ocean in this article? (the English language is funny how it gives so much freedom; in German - my native tongue - it's clearer: nouns (and names) have a capital letter, other words don't.)

== Hatnote ==

Per a discussion at the Vital-2 Talk page, I added a hatnote here to match the one at [[Sea]]. Does everyone feel it is okay? Thanks :)

[[User:LightProof1995|LightProof1995]] ([[User talk:LightProof1995|talk]]) 04:26, 9 March 2023 (UTC)
: Could you send the link to the discussion at the Vital-2 Talk page (oh wait, I found it here: https://en.wikipedia.org/wiki/Wikipedia_talk:Vital_articles/Level/2)? I am curious. I am undecided if we really need a hatnote. The hatnote at [[Sea]] is more important and it says "{{tq|This article focuses on human experience, history and culture of the collective seas of Earth. For natural science aspects, see more at [[Ocean]]. For individual seas, see [[List of seas]]. For other uses, see [[Sea (disambiguation)]] and [[The Sea (disambiguation)]].}}". I am saying "more important at Sea" because the "Sea" article has to justify its existence more than the "ocean" article does (I had once proposed to redirect and merge Sea to Ocean but was not successful with my proposal; that split into cultural (Sea) versus natural sciences (Ocean) kind of works, I guess). 
: If there is consensus to have a hatnote at Ocean, I would use the About template as follows: <nowiki>{{About|Natural science aspects of oceans|more on human experience, history and culture of oceans|Sea|Other uses|Ocean (disambiguation)}}</nowiki> which would convert to {{tq|This article is about natural science aspects of oceans. For more on human experience, history and culture of oceans, see [[Sea]]. For other uses see [[Ocean (disambiguation)]]}}. 
: Compared with the current proposal of LightProof1995 which is {{tq|This article focuses on the science aspects of oceans, both on Earth and on other planets. While it covers some historical and cultural aspects, more can be found at'' [[Sea]]''.

== How many oceans? ==

The content saying that there are five oceans (on earth), has two refs.  I don't have access to the OED one, but the Webster's ref. does not name or give a number for the number.  The simple English, Russian and German Wikipedia articles all agree; however, I have heard the number seven also given, with the Pacific and Atlantic both being divided into north and south.  This pretty authoritative source gives one world ocean and five commonly accepted ones but notes that not all countries have moved beyond the traditional four: https://oceanservice.noaa.gov/facts/howmanyoceans.html .   This site is pretty much consistent with the Encyclopedia Britannica, which says, "Functionally speaking, there is really only one ocean, since every demarcated ocean is connected to at least two others" after talking about the 4+1 that NOAA discusses.  And https://encounteredu.com/cpd/subject-updates/learn-more-how-many-oceans-are-there says it depends, citing  1-, 3-, 4-, 5-, and 7-ocean interpretations.  I think our article should present at least some of this. [[Special:Contributions/2600:6C67:1C00:5F7E:C86B:40D2:FD06:529A|2600:6C67:1C00:5F7E:C86B:40D2:FD06:529A]] ([[User talk:2600:6C67:1C00:5F7E:C86B:40D2:FD06:529A|talk]]) 23:37, 1 April 2023 (UTC)

== Protection - Intergovernmental Oceanographic Commission ==

Hi [[User:EMsmile|EMsmile]], 

I saw that you had deleted my little paragraph the "protection" section. I was talking about the [[Intergovernmental Oceanographic Commission]] (IOC), the UN Decade of Marine Science for Sustainable Development (2021-2030), the [[Convention on the Protection of the Underwater Cultural Heritage]], the [[Global Ocean Observing System|GOOS]] and [[UNESCO Global Geoparks]]. I understand that it is important to get to the point, but I think it is also important and interesting for this article to mention at least the IOC and the Convention. The IOC is the UN body responsible for supporting oceanography and ocean services since 1960. The IOC is helping UN member states to achieve the 2030 Agenda and the Paris Agreement on climate change. Would you agree that we should add it to the article?

Thank you very much, I am at your disposal for any discussion on this subject!  [[User:E.poul|E.poul]] ([[User talk:E.poul|talk]]) 13:52, 5 April 2023 (UTC)
: Hi [[User:E.poul|E.poul]], that content is important but keep in mind that the [[ocean]] article is a very high level overview article, so we cannot dive into detail on every topic. That's what all the connected sub-articles are for. This was your text that I had deleted: {{tq|Through the [[Intergovernmental Oceanographic Commission]] (IOC), UNESCO is supporting global ocean sciences<ref>{{Cite web |title=IOC-UNESCO {{!}} IOC UNESCO |url=https://ioc.unesco.org/node/2 |access-date=2023-03-30 |website=ioc.unesco.org}}</ref>. The Organization is also leading the implementation of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030)<ref>{{Cite web |title=Ocean Decade – The Science We Need For The Ocean We Want |url=https://oceandecade.org/ |access-date=2023-03-30 |language=en-US}}</ref>. The [[Convention on the Protection of the Underwater Cultural Heritage|Convention on the protection of the Underwater Cultural Heritage]], the [[Global Ocean Observing System]] and [[UNESCO Global Geoparks|UNESCO's Global Geoparks]] are also ways to protect the marine ecosystem.}} Consider adding it to [[Marine conservation]] rather? In general, rather look for the sub-articles if you want to add content that is related to UNESCO's work. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 13:08, 18 April 2023 (UTC)

== Ga is unclear ==

“By 3.5 Ga”, something something ocean started cooling. This is the only instance of Ga being used on page instead of billions of years. No nearby billions of years includes (Ga) for reference.  [[User:Detspek|Detspek]] ([[User talk:Detspek|talk]]) 15:31, 25 April 2023 (UTC)

== Added more content about pH, temperature and stratification ==

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. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 09:47, 9 May 2023 (UTC)

== Improving readability ==

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.

== Unclear term in introduction ==

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? [[User:Ribidag|Ribidag]] ([[User talk:Ribidag|talk]]) 12:25, 2 June 2023 (UTC)
: I agree with you that this is unclear. I'll check with Tim Jickells who has been helpful with this article in the past. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 06:57, 14 June 2023 (UTC)
:: I got the following answer from Tim: "Sorry for any ambiguity over the 1% light thing. I quote below a sentence from Grant Bigg's book which I hope is unambiguous. "The euphotic zone is defined to be the depth at which light intensity is only 1% of the surface value" p36 The Oceans and Climate Grant R Bigg Cambridge University Press. I don't know if you want to actually use this reference or simply edit the existing text to be unambiguous, I'll leave that up to you. The basic concept is that with that little light photosynthesis is unlikely to achieve any net growth over respiration. The actual optics of light reflecting and penetrating at the ocean surface are complex, but I think this approach to the euphotic zone is pretty universal. " I'll try to improve the wording accordingly. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 07:56, 15 June 2023 (UTC)

::::: Hi [[User:Pbsouthwood|Peter Southwood]], I am a little bit unsure of this edit of yours: https://en.wikipedia.org/w/index.php?title=Ocean&diff=prev&oldid=1160773618 . As I had included the sentence in quotation marks, it's a direct quote from the book so we cannot change it in the way you have changed it. Maybe we leave the quoted sentence as is but we rather add your additional explanation after the quote (but maybe not in the lead but in the main text). The quoted sentence was: {{tq|The <nowiki>[[photic zone]]</nowiki> 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 {{tq|... 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 {{tq|... the depth at which light intensity is still at least 1% of the surface value"}}. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 08:09, 19 June 2023 (UTC)
:::::::{{U|EMsmile}}, {{tq|... 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.

::::::We could say: ''The euphotic zone  is the layer of water in which the natural light intensity is at least 1% of the surface value.'' (correct, but maybe not sufficiently clear to all readers) It extends continuously from the surface to the depth at which intensity has dropped to 1%, typically at about 200 m in the open ocean, and light intensity decreases continuously with increasing depth. &middot; &middot; &middot; [[User:Pbsouthwood|Peter Southwood]] [[User talk:Pbsouthwood|<sup>(talk)</sup>]]: 17:57, 19 June 2023 (UTC)
::::::: Yes, I think that sounds OK. So we leave off the quotation marks but keep the reference and page number? (some people would put the quote into the ref so that it appears in the ref list at the end) Perhaps it would also be good to state that photic zone and euphotic zone are the same thing (they are, aren't they?). - The reason why I had originally used quotation marks is because I was scared of either being hit with [[WP:close paraphrasing]] or that I would change the exact meaning by mistake... But I agree that quotation marks look inelegant here. - Make sure to change it not just in the lead but also in the main text. Thanks.

== More content on ocean density or even a separate article? ==

I'd like to bring to your attention a proposal by [[User:Pbsouthwood|Peter Southwood]] to have a separate article on [[density of seawater]], see here: https://en.wikipedia.org/wiki/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. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 11:28, 18 June 2023 (UTC)
: I've asked Tim Jickells about that and here's his input: "Hi Elizabeth, I'm not quite sure what to say about the density questions. It's really an issue for physical oceanographers. Density is really fundamental to ocean circulation, it ultimately drives the whole thermohaline circulation. The section in "[[seawater]]" wiki is nice and short but doesn't really tell you much about how the density changes (with temperature and freshwater/salt mixing) which is really important. The section in the [[Ocean stratification]] wiki starts well in explaining density, why it matters and what drives changes in it. There are then that rather daunting set of equations. I assume these are correct but I'm not the person to ask that. However, I suspect they may frighten off many wiki readers. I think this is an editorial issue for you and your colleagues but personally I'd leave the "ocean circulation" section much as it is but perhaps just add a bit of text that says for those interested in the mathematical representation of this, here's the relevant equations but make clear that they don't need these to go on to the next section. Here speaks a chemist not a physicist or mathematician!" [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 11:01, 20 June 2023 (UTC)

== Overly detailed info box? ==

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 ([https://www.ripublication.com/ijome22/ijomev12n1_03.pdf 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):

:Hi. Well I do see the lengthyness of the infobox, but even more I have quite streched the understanding of the sections since e.g. one section of the infobox in question says "Max depth", so I concede that only "deepest point" and not also "lowest point" fits. Same with "coordinates" section.
:Though since I find the information and differentation important Ill find a spot in the main body. [[User:Nsae Comp|Nsae Comp]] ([[User talk:Nsae Comp|talk]]) 20:38, 26 June 2023 (UTC)
:: Thanks for moving it out of the infobox. However, if you want to use this content in the main text, can you please find a more reliable source for it? This one has been flagged as unreliable and I also find it odd that the link goes directly to a pdf file, not a journal location with a DOI: {{tq|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 {{cvt|6,351.704|km|0}} from Earth's centre, {{cvt|5.449|km|0}} below sea level, which makes it {{cvt|14.726|km|0}} closer to Earth's centre than the Challenger Deep.<ref name="ripublication.com">{{cite web |title=''Revisiting "Ocean Depth closest to the Center of the Earth"'' |url=https://www.ripublication.com/ijome22/ijomev12n1_03.pdf |accessdate=18 September 2022 |publisher=Arjun Tan, Department of Physics, Alabama A & M University |language=English}}</ref>}} The "unreliable" flagging is from [[User:Headbomb/unreliable|this script by Headbomb]].

== Content about Earth's outer core not needed here ==

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 {{cvt|2260|km|mi}}. It lies above the Earth's solid [[inner core]] and below the Earth's semisolid [[Earth's mantle|mantle]]. The outer core ocean begins approximately {{cvt|2889|km|mi}} beneath the Earth's surface at the outer core-mantle boundary and ends {{cvt|5150|km|mi}} beneath the Earth's surface at the outer core-inner core boundary.<ref>{{cite web |date=18 January 2017 |title=Earth's Interior |url=https://www.nationalgeographic.com/science/earth/surface-of-the-earth/earths-interior/ |access-date=14 November 2018 |website=Science & Innovation |publisher=National Geographic}}</ref><ref>{{Cite web |last=Sue |first=Caryl |date=2015-08-17 |editor-last=Evers |editor-first=Jeannie |title=Core |url=https://www.nationalgeographic.org/encyclopedia/core/#:~:text=The%20outer%20core%2C%20about%202%2C200,%C2%B0%20and%209%2C932%C2%B0%20Fahrenheit). |access-date=2022-02-25 |website=National Geographic Society |language=en}}</ref><ref>{{Cite journal |last1=Zhang |first1=Youjun |last2=Sekine |first2=Toshimori |last3=He |first3=Hongliang |last4=Yu |first4=Yin |last5=Liu |first5=Fusheng |last6=Zhang |first6=Mingjian |date=2014-07-15 |title=Shock compression of Fe-Ni-Si system to 280 GPa: Implications for the composition of the Earth's outer core |journal=Geophysical Research Letters |volume=41 |issue=13 |pages=4554–4559 |bibcode=2014GeoRL..41.4554Z |doi=10.1002/2014gl060670 |issn=0094-8276 |s2cid=128528504 |doi-access=free}}</ref><ref>{{Cite journal |last1=Young |first1=C J |last2=Lay |first2=T |date=1987 |title=The Core-Mantle Boundary |url=https://www.annualreviews.org/doi/10.1146/annurev.ea.15.050187.000325 |journal=Annual Review of Earth and Planetary Sciences |language=en |volume=15 |issue=1 |pages=25–46 |bibcode=1987AREPS..15...25Y |doi=10.1146/annurev.ea.15.050187.000325 |issn=0084-6597}}</ref> [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 08:20, 3 July 2023 (UTC)

:Then, the name of this article should be "Ocean on Earth", if you would like to delete the section "Extraterrestrial oceans". Your arguments for deleting the sections I wrote ("[[Magma ocean]]" and "[[Earth's outer core]]") contradict to this very article because of the very existence of the "Extraterrestrial oceans" section in this very article, and that section you refused to delete, and thus discriminating me as an editor from editors who wrote the "Extraterrestrial oceans" section in this article, and discrimination on Wikipedia is unacceptable. If the "Extraterrestrial oceans" is in this article, then readers need to know about the existence of other oceans too, not only "the salty water on Earth", why geocentrism here?[[User:Bernardirfan|Bernardirfan]] ([[User talk:Bernardirfan|talk]]) 17:32, 3 July 2023 (UTC)

:: Copied another, very similar comment by User:Bernardirfan from my talk page (this belongs on the article talk page not on the editor's talk page): "Hello! You deleted, pardon, removed two new sections I wrote ("Magma ocean" and "Earth's outer core") because you are "not convinced this content is needed here. We don't need to mention any kind of term that has the word "ocean" in it, when the core topic of this article is clearly spelled out in the first sentence: salty water on Earth.". Then, what the section "Extraterrestrial oceans", which are obviously not on Earth, is doing in this article? Will you delete that section as well? Your argument contradicts to this very article. "Extraterrestrial ocean" means "ocean that is not on Earth". And "two types of oceans" is not equal to "any kind of term that has the word "ocean" in it". You are not convinced, well, sorry, but I am convinced. There is a whole article about the magma ocean, and it needs to be mentioned here for readers, as a link to the "Magma ocean" article, so readers can get more info about the magma oceans by clicking the link in the "Magma ocean" section. And yes, a magma ocean is an ocean, read the "Magma ocean" article, readers must be informed that other types of oceans exist, not only those of "salty water on Earth", no matter of your personal opinion." [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 19:29, 3 July 2023 (UTC)
::: The hatnote and the first sentence of the article makes it very clear that his article is about water oceans on Earth. I agree the section "Extraterrestrial oceans" doesn't actually fit either. I suggest it's moved to a sub-article. That sub-article (depending on its scope) could then also contain your new content about [[magma ocean]], or a link to that article as a sub-article. Same with the content about [[Earth's outer core]]. This is has nothing to do with "geo-centrism" but it has to do with [[WP:COMMONNAME]], please review this policy and you'll see why this article is called [[ocean]] and not [[water ocean on Earth's surface]]. Note we already have [[Ocean (disambiguation)]]. You could use that as a starting point to figure out where your proposed content would fit best. It doesn't fit at [[ocean]] and neither does the section on "Extraterrestrial oceans". Those kinds of things could be mentioned under "See also" if needed. - Let's see what other page watchers think about this? [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 19:36, 3 July 2023 (UTC)
:::: The relevant article for extraterrestrial oceans is most likely [[Planetary oceanography]]. I think we simply move the section to there, and just leave a link behind. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 19:53, 3 July 2023 (UTC)
:::::Then remove all sections about non-Earth oceans, and eventually rename the article to "Oceans on Earth" or similar.
:::::OR
:::::Do not delete my sections about non-water and non-earth oceans and the other editor's section named "Extraterrestrial oceans" in the article, and leave the title of this article as "Ocean", because the term "ocean" refers not only to the salty water oceans on Earth, but to [[magma oceans]] either on Earth or on another planets and natural satellites, water ocean on [[Europa]], liquid hydrogen ocean on [[Jupiter]], possible liquid carbon ocean on [[Uranus]] and [[Neptune]], hydrocarbon oceans on the [[Saturn]]'s moon [[Titan (moon)|Titan]], etcetera. In the "Extraterrestrial oceans" section, I added a link to the main article "Magma ocean", for readers to click on it if they want to know more about magma oceans, and the editor EMsmile added the magma oceans paragraph at the end of the "Extraterrestrial oceans" section, so, thanks to that editor. [[User:Bernardirfan|Bernardirfan]] ([[User talk:Bernardirfan|talk]]) 20:44, 3 July 2023 (UTC)
:::::: Your first option is likely the way forward but we are for sure NOT going to rename this article. Please read [[WP:Commonname]]. It explains very clearly why "ocean" is exactly the right title for this article. If anyone gets to this page and is still confused because they wanted to read about oceans that are not water on Earth, they can easily click through to [[ocean (disambiguation)]] from the hatnote! [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 21:37, 3 July 2023 (UTC)
::::::: So as there has been no further objections, my plan is to move the section that is called "Extraterrestrial oceans" to [[Planetary oceanography]] in the next few days. I'll also move the section "Earth's outer core", probably to [[Earth's outer core]] if the content isn't there already. None of the 3 refs provided in that section use the phrase "an ocean of molten iron and nickel inside Earth" by the way. [[User:EMsmile|EMsmile]] ([[User talk:EMsmile|talk]]) 17:19, 4 July 2023 (UTC)
:::::::: I've moved the content now. I don't know where to move this content to, should it go to [[Earth's outer core]]?
