GA review (see here for what the criteria are, and here for what they are not)

---

Welcome to GA! This is my first time reviewing an article in this topic area, so I may have questions about the topic.

1. It is reasonably well written.

   a. (prose, spelling, and grammar):

   See the copy changes below.

   b. (MoS for lead, layout, word choice, fiction, and lists):

   Consider beefing up the lead section a bit to be more representative of the article content. MOS:LEAD

   @Sammi Brie: Lead section was expanded. Reego41 13:50, 26 March 2023 (UTC)

2. It is factually accurate and verifiable.

   a. (reference section):

   b. (citations to reliable sources):

   Given the track record of the lead author (Chadwick), I am OK with the Frontiers in Marine Science paper as expert self-published even though the journal publisher is possibly predatory.

   c. (OR):

   d. (copyvio and plagiarism):

   Earwig mostly flagged titles of other cited works.

3. It is broad in its coverage.

   a. (major aspects):

   b. (focused):

4. It follows the neutral point of view policy.

   Fair representation without bias:

5. It is stable.

   No edit wars, etc.:

6. It is illustrated by images and other media, where possible and appropriate.

   a. (images are tagged and non-free content have non-free use rationales):

   b. (appropriate use with suitable captions):

   Encouragement: Add alt text.

7. Overall:

   Pass/fail:

   Mostly copy changes. I'd like to be walked through ref 5 since it is very hard to verify for a non-expert editor. Ping me when you're done and if you have any questions.

(Criteria marked are unassessed)

Copy changes

• The seamount is mostly known for its 2009 eruption, where it erupted pillow lava and tephra into the water from 2 vents. The "2" should be "two". See MOS:NUMERAL. There are a few more instances of this in the article.

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• The east-northeast rift zone curves towards the east as it deepens and the west-southwest rift zone is west‐oriented towards its end. This needs a comma after "deepens" because you can split this into two sentences. Read User:Sammi Brie/Commas in sentences, which I wrote to help GA nominators parse this.

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• "a lot of" maybe "many" would sound better

Fixed, you're not wrong. Reego41 11:55, 26 March 2023 (UTC)

• "were the Pacific Plate" should be where

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• I see the use of NE for Northeastern as an abbreviation is common in the academic literature. Should we spell it out or follow the literature's lead?

I think both of them work. If NE isn't understandable and prose enough, I can replace it with northeast/northeastern. I'm going to let NE stay. Reego41 11:55, 26 March 2023 (UTC)

• On the northern border of the basin can be found in the area where the Tonga Trench subduction transitions into convergent strike-slip where the direction of the faulting also changes from north–south to northwest–southeast. Very awkward sentence... I don't see a subject. What can be found in the area? This could be two sentences, honestly.

Fixed. The "in" in the first section of the sentence messed everything up, even I had trouble understanding it. I split it into 2 sentences, and reworded them. It should be more clear now. Reego41 11:55, 26 March 2023 (UTC)

• Capitalize "Lau Basin" consistently

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• The NE Lau Basin has one of the highest upper mantle temperatures in the world, has one of Earth's coolest slab thermal parameters which is caused by the speed of convergence of the slab into the crust and its age and has among the highest slab water flux values of any oceanic subduction zone. An Oxford comma after "age" would tremendously help reading here. I'd also consider setting off "which is caused ... age" somehow.

At first I couldn't understand what the age was referencing in the paper but now I think the age refers to the age of convergence. So the cool slab thermal parameters are caused by the convergence speed and the convergence age. That's what I understand. Reego41 12:02, 26 March 2023 (UTC)

• These factors cause ... and causes Should be "cause" instead of "causes" to agree with the plural "factors".

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• West Mata and the surrounding NE Lau Basin is home should be "are" home

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• The hydrothermal ecology of the Lau Basin is home to many endemic organisms including the Lamellibrachia columna which shows similarity to Lamellibrachia satsuma that can be found in Japan, Neobrachylepas relica which are a close relative to the Brachylepadomorpha which was extinct since the Miocene and more. This needs some grammar fixing. Try... The hydrothermal ecology of the Lau Basin is home to many endemic organisms, including the Lamellibrachia columna which shows similarity to Lamellibrachia satsuma that can be found in Japan; Neobrachylepas relica, a close relative to the Brachylepadomorpha which was extinct since the Miocene; and more.

Fixed. Replaced it with your recommendation, works perfectly. Reego41 11:55, 26 March 2023 (UTC)

• Hades was erupting with frequent magma bursts meanwhile Prometheus was showing a rapid degassing eruption. This needs punctuation. Add a semicolon after "bursts" and a comma after "meanwhile".

Fixed. Reego41 11:55, 26 March 2023 (UTC)

• Elevation changes at the flanks of the volcano were observed over the years, pointing out that West Mata has had many landslides at the years of the eruption. These landslides were observed by hydrophones and bathymetric surveys at the area over the years. The second sentence is redundant to the first; consider reconfiguring.

Fixed. Merged the sentences. Reego41 11:55, 26 March 2023 (UTC)

• Following the main eruption, several papers (including Chadwick Jr et al. 2019) suggests that in 2010–11 Several papers suggest.

Fixed. Removed the paper in the parentheses as well. Reego41 11:55, 26 March 2023 (UTC)

Spot checks

• 2: Height. Its pre-2011 summit at 1159 mbsl rose from a base at ∼2900 mbsl Y
• 3: The details cited to Chadwick appear to be reproduced faithfully. See the note above. Y
• 5: Unsure how to parse this list of vents. Is "active, confirmed" what vouches for the source? It seems right, but again, not my field.

No idea why, but I seem to have cited the list to active hydrothermal vents. I replaced it with a page on the website dedicated to West Mata ([1]). Reego41 11:14, 26 March 2023 (UTC)

Almost there @Reego41... Can you tell me how the West Mata page supports the sentence Compared to these volcanoes, West Mata is the most hydrothermally active one, and its activity is not disputed? Cuz I'm having some trouble. Sammi Brie (she/her • t • c) 17:54, 26 March 2023 (UTC)

@Sammi Brie Oh, now I get why I put the link to the list. I put the list because the pages dedicated to the volcanoes nearby don't all say it's hydrothermally active, but ehh...

I guess I'd be better off without that sentence. Reego41 15:18, 27 March 2023 (UTC)

Any updates? @Sammi Brie: Reego41 08:28, 1 April 2023 (UTC)

I just blanked on passing this. Let me do that now. My bad. Sammi Brie (she/her • t • c) 18:27, 1 April 2023 (UTC)

• 13: An extant representative of the Brachylepadomorpha, Neobrachylepas relica gen. et sp. nov., has been discovered associated with hydrothermal vents in the Lau Basin. Y

West Mata erupting underwater.

• ... that the two vents of West Mata (pictured), an underwater volcano, are called "Hades" and "Prometheus"? Source: NOAA "In 2009, the first ROV dives at West Mata Volcano discovered active volcanic activity and hydrothermal venting associated with primarily two vents on the central promontory: Hades and Prometheus..."

Overall: @Reego41: Good article. But, it says in the source quote that the vents were on the central promontory and the entire volcano. So are those the only two vents on the volcano? Also, I would like some wikilinks to Hades and Prometheus but it's fine either way. Onegreatjoke (talk) 20:50, 3 April 2023 (UTC)

@Onegreatjoke: Hades and Prometheus aren't the only vents on West Mata, it's just that they were the first ones discovered in 2009 and because they're located near the summit. Since West Mata is a fissure volcano, it has many many vents but Hades and Prometheus are the more significant ones. Reego41 14:18, 4 April 2023 (UTC)

• @Onegreatjoke: The source doesn't talk about any other vents, as far as I can tell, but this can be easily remedied. How about this:
• ALT1: ... that the two active vents of West Mata (pictured), an underwater volcano, are called "Hades" and "Prometheus"?
• 〜 Festucalex • talk 03:32, 4 April 2023 (UTC)

Works for me. Reego41 14:18, 4 April 2023 (UTC)

Seems fine Onegreatjoke (talk) 19:21, 5 April 2023 (UTC)

It looks to me like ALT1 has the same problem: we don't know that these are the only two active vents. The source implies there may be others: active volcanic activity and hydrothermal venting associated with primarily two vents on the central promontory: Hades and Prometheus (my emphasis). This is easily resolved by removing the word "the" from the hook. Sojourner in the earth (talk) 06:02, 6 April 2023 (UTC)

@Sojourner in the earth: Or maybe we take ALT1 and replace "active" with "primary". Pinging the others: @Onegreatjoke: @Reego41: 〜 Festucalex • talk 18:29, 6 April 2023 (UTC)

• ALT2: ... that the two primary vents of West Mata (pictured), an underwater volcano, are called "Hades" and "Prometheus"?

That does seem better. Reego41 07:50, 9 April 2023 (UTC)

That looks okay. Reaffirming tick and striking the other hooks just to be clear. Sojourner in the earth (talk) 16:25, 9 April 2023 (UTC)
