Talk:Water distribution on Earth

Deep underground water

I don't have the technical background to insert it, but can someone please read this article and comment on how it changes the scientific view of the water cycle? Deep Earth has oceans' worth of water, $10 diamond reveals: University of Alberta researchers find 'meteorite mineral' that formed naturally on our planet Thanks, --Kevlar (talk • contribs) 22:55, 12 March 2014 (UTC)

Yeah, this needed some mention, I've reworded the introduction and started a stub at Water in Earth's mantle.Forbes72 (talk) 19:02, 13 March 2015 (UTC)

Water in earth

Re [1] The reference -- a reliable source quoting another reliable source, clearly says "water." NE Ent 14:23, 1 October 2015 (UTC)

I can't access the full article except this sentence: "The bulk of Earth’s water, hidden deep underground, has a slightly different composition from that of ocean water." Could that "slightly different composition" be "the components of water (hydrogen and oxygen) are held within mantle minerals as hydroxide ions"? I also fixed the sentence you just deleted at the Water in Earth's mantle article. Raquel Baranow (talk) 15:04, 1 October 2015 (UTC)

No, it's talking about isotopes of the atoms, not chemical composition.NE Ent

Two issues here. First the Science News article is quoting from an address by an astronomer at the International Astronomical Union meeting regarding isotopic differences in the water components of ocean water vs deep earth hydroxide vs water in comets from the viewable blurb for those of us w/out access. It would be nice to see a peer reviewed source.
Second, the "water" in the mantle isn't water as H₂O, rather it is the hydroxide (OH) content of a silicate mineral that isn't stable under the conditions of Earth's surface where water (H₂O) is stable. Relying only on popular news blurbs, press releases etc for writing articles can be/is problematic and misleading. The Scientific American article mentions this in passing, but continues to refer to Earth's deepest ocean. The article also discusses the subduction of water rich oceanic crust (basalt and sediments) into the mantle at subduction zones. The SA article quotes: a significant portion of the water in the mantle transition zone is from the emplacement of these slabs. Vsmith (talk) 14:34, 3 October 2015 (UTC)

Relying primarily on secondary sources is actually policy: WP:SCHOLARSHIP "Articles should rely on secondary sources whenever possible. For example, a review article, monograph, or textbook is better than a primary research paper. When relying on primary sources, extreme caution is advised: Wikipedians should never interpret the content of primary sources for themselves." Since what the articles mostly say is simply "water" -- not "liquid water," not "hydoxide," Wikipedia should simply say water. Of course it's fine to add a note about the water in the mantle transition zone, if desired, as long as that is not extrapolated to a conclusion about all water beneath the crust. NE Ent 15:12, 3 October 2015 (UTC)

Yup, best to let the reader visualize Earth's deepest ocean as a vast body of water sloshing around in some huge mantle cavity. :) Vsmith (talk) 17:46, 3 October 2015 (UTC)

So we shouldn't refer to it as "water sloshing around" but "water bound in minerals, and it's several hundred miles beneath the Earth's crust." I.e., it's not a practical solution to mine it to solve drought problems. I don't see any reliable sources saying we can mine it. Here's a fringe science website that advocates mining it. It looks like a scheme to get money from investors. Raquel Baranow (talk) 19:01, 4 October 2015 (UTC)

This "water" in the earth mantle/interior is seriously misleading, especially in the lede. The way it's worded it sounds like there is actual water there when it is just theoretical and in the form of ions or minerals. I'm going to remove it all unless this is properly worded in the article. Raquel Baranow (talk) 14:59, 7 October 2015 (UTC)

Merge proposal

Water in Earth's mantle should merged into this article as it does not contain enough distinct content to warrant a separate article. NE Ent 21:36, 1 October 2015 (UTC)

Merge and rewrite to dilute the news hype per above comment. Vsmith (talk) 14:34, 3 October 2015 (UTC)

Duplicate images on top right

The two images on the top right appear to be nearly identical; are both needed? CoolieCoolster (talk) 22:55, 28 February 2017 (UTC)

Linking my Wikipedia article

I am linking my Wikipedia article on the deep Earth water cycle to this page, under the section "Water in Earth's Mantle." Smcminn1234 (talk) 07:49, 12 March 2019 (UTC)

Question of difference with another Wikipedia article

This article confidently states that the amount of water in the mantle is equal to the water in the Earth's oceans. The article on the "Deep water cycle" https://en.wikipedia.org/wiki/Deep_water_cycle says estimates range from 1/4 to 4 times the amount in the oceans, and relies on an older source. (https://en.wikipedia.org/wiki/Deep_water_cycle#cite_note-Hirschmann630-10) Is that estimate out of date, such that equality is now the correct estimate, and if so should not that article be updated to match this one? 98.244.76.229 (talk) 17:11, 29 October 2020 (UTC)

possible water reservoirs inside Earth

Edited the deep water section of the article, and added that the water stored inside Earth is much less understood than its surface counterpart. The actual amount of water inside the planet is still under debate. Updated the numbers and the references accordingly. --Dong2j (talk) 20:09, 12 January 2021 (UTC)

The lead is not a good summary of the article

I have just noticed that the lead of this article is not very good as per WP:LEAD. It should be a good, concise summary. I'll try to do some work on it. EMsmile (talk) 12:14, 2 June 2021 (UTC)

I've moved some content from the lead to the main body, in order to transform the lead into a better summary of the article. There was content in the lead that appeared nowhere in the article itself which is not good practice. EMsmile (talk) 12:28, 2 June 2021 (UTC)

on Section ==Variability of water availability==

Can the writer or anybody help add more citations to support the saying in the 1st 2 paragraphs? As a layman, I'm not convinced by the wordings. As for 3rd, 4th and 5th paragraphs, citations are also needed. Thank you for your kind attention. ThomasYehYeh (talk) 13:57, 3 July 2023 (UTC)
