Talk:Seismic velocity structure

Peer feedback from Morris

Hi Louis,

Your work is amazing! The contents are well-structured and easy to follow. Here are some comments:

1. I like the list of methods to study velocity structures of planets, looks comprehensive. Perhaps the methods can be discussed in more detail and placed before the illustrations of the velocity structures in various terrestrial bodies. Readers will learn about the methods and how they contribute to the findings of the velocity structures on Earth and beyond.

2. Interesting to point out some recent research advancements in velocity structures, say the hypothesis of an inner core boundary. Maybe a few more sentences can help explain the rationale (the connection between the travelling time anomaly and its existence) and possible implications.

3. Instead of giving an overview of the future plans, you may as well mention the objectives/ breakthroughs in them and how they could address the current limitations (if any).

Keep up the great work!

Cheers!

1. May rephrase some sentences to make expressions clearer, e.g. "While light elements also present in the inner core modulate this velocity, their impact is relatively contained."

2. Minor formatting issues: Can consider using the same expression wordings for describing the behaviour of P- and S-waves in the planets.

3. Some paragraphs may have more referencing/ hyperlinks. Overall the page looks professional!

Hi Louis,

Great work! The page makes rich use of figures to enhance readers' understanding throughout the content. These visual aids can effectively illustrate complex concepts and processes. Here are some comments:

1. The section of Method could be placed after the Principle of Seismic Velocity Structure and before the Velocity Structure of different celestial body to facilitate a smoother transition of content.
2. May also mention the impacts of the proposed future plan to raise the significance of having such space mission.
3. A figure contrasting the difference between the velocity structure of the Earth in 20th and 21st Century may added to demonstrate the actual improvement brought by the advancement in seismic tomography and the expanding GSN.

Welldone!

Cheers,

1. Avoid using abbreviation (e.g. PKJKP, I don't understand it even after checking anther page linked to it)
2. Some technical terms can be explained briefly or bluelink them (e.g. non-unique solutions, iterative, Snell's Law... )
3. Some minor positional issue of the figures inside the table.

Feedback from Jasmine

1. Could maybe have a section dedicated to P-waves and S-waves, their characteristics etc and maybe a figure to help describe them to the reader.

2. Structurally would make sense to have the sections for velocity structure of Earth, Moon, Mars and Enceladus at the end of the page in an 'examples' section or after the applications section.

3. Double check the hyperlinks in the methods table as the last two for ANT and FWI do not lead to a page.

Great page!

1. Proof read for misplaced/missing punctuation and the odd spelling mistake - there's not many at all just a couple of bits at the start.

2. Could expand on terms such as Snell's Law in text, diagram shows this well but would benefit from a basic sentence explaining the law. Also a breakdown of the terms PKIKP wave and acoustic impedance in methods section.

Feedback from Tony

1. Label the x- and y-axes of the velocity graph in “velocity structure of Earth”.

2. It would be better to use table to list all P-wave and S-wave velocities of each planet.

3. Appreciate your hard work in writing this page. The “Velocity Structure of Enceladus” section, however, doesn't seem to be consistent with other sections, as it is not informative enough when compared to other sections. It would be difficult for readers to compare the velocity structures of enceladus with other terrestrial bodies. — Preceding unsigned comment added by Ngeo21*gnik (talk • contribs) 01:55, 25 October 2023 (UTC)

2nd Feedback

1. Little typo in the introduction.

2. Final part of “Velocity variation of seismic velocity structure”: Give a picture of impact basins could help readers to understand slightly better.

3. Velocity Structure of Mars: for “lower mantle”, the depths of that 2 transition zones can be added to the graph.

4. Can “Future Plan” be the last part after “Limitation/Uncertainty”? — Preceding unsigned comment added by Ngeo21*gnik (talk • contribs) 17:31, 16 November 2023 (UTC)

Comments from Graeme

Hi Louis, I will put my suggestions here:

1. Thanks for writing this.
2. You have used a suitable style and language level so that is great!
3. Recent news is that the lower mantle of Mars is liquid, and that the core is more Earth-like than previously thought, so your table could take that into account.
4. you say "the reduction in seismic velocity in the outer core is partly due to the presence of lighter elements" -- how sure is that or is it an unconfirmed speculation?
5. Lateral variation is mentioned for the Moon, but I did not see it for Earth's Crust and uppermost mantle until there is a mention in "Application".
6. Reduce use of abbreviations that are non common. Some of these are not required, eg CMB; but others like "PKIKP" should be retained as that is the overwhelming use of the term.
7. Put the name of the topic in bold: Seismic velocity structure;
8. Headings should be in sentence case, so only first word capitalised.
9. For your graph or diagrams, use .svg format as that can be more easily edited, and have text changed for other languages;
10. On your first graph the caption could include the meaning of V_s, and V_p as the in-diagram legend is very small. (Perhaps it could be bigger)
11. "beneath the Earth's surface and other planetary bodies" - slightly awkward as it is not clear that it is beneath the surface of other planetary bodies.

Reflection for the wiki page assignment

I learnt how to quickly read papers and look for the main points (the scientific method) of academic papers while making this wiki page. This page is no doubt a chance for me to enhance my understanding of the selected topic. It is also a chance to improve my writing and organisation skills.
