Talk:Magnetic field of Mars

First Brief Peer Review edit

Based on Christopher Noll's great comments, I 1) made links to some vocabularies and 2) added some summary to the leading section. I also added figures and corrected some grammatical errors.

Second review edit

This is a great page! It has enough explains and nice figures that can help readers’ understanding of the martian magnetic fields. There are only a few suggestions and questions about terms and concepts for the second review.

1. For some terms like ‘thermal remanent magnetization (TRM)’ and ‘magnetic reversals’, how about briefly explaining them or inserting a link to them? I found that they don’t have their own Wikipedia pages, but you can still insert an external link to each word. That would help readers understand this article better.

2. (This can be a miscellaneous point, but I just wanted to mention.) In the ‘Mars crustal magnetism’ part, you mentioned that the ground-level data gave an order of magnitude higher value than that of the satellite data. However, according to the figure you inserted, the highest crust field values from the MGS seem to be 30 nT, which makes two orders of magnitude difference from the ground-level data (2 uT). Should this value be corrected? If the actual value for the comparison was different, it would be great if you can briefly mention the average value of the crustal magnetic field from the MGS satellite in the main article so that readers can easily grasp the intensity differences.

Other than those points, this article nicely explains the concepts and is easy to understand. I learned a lot about the martian magnetic fields. Good luck with your final revision and publication! -Mhan818 (talk) 08:31, 7 March 2022 (UTC).Reply

Thanks so much for your valuable review
  1. I wrote the definition of TRM and changed some wordings. I made a link to reversals (geomagnetic reversals)
  2. Good point. I did not write the detailed caption for the figure you mentioned- Sorry. Actually, I think the figure shows the 2 orders of magnitude variations, not the actual intensity (I looked over other papers but it has like 200 - 600 nT for southern hemisphere). I added the caption and also added the averaged southern hemisphere crustal magnetization intensity of ~220 nT, which is from the same paper!

1. Based on Simon's comment, I rewrote the "Alternating Stripes" section to reduce the confusion of the intermittent dynamo perspective.
2. Based on Wendy's comment, I added Steven's dynamo mechanisms (and table of possible dynamo mechanisms)
3. Also, after I read about many dynamo mechanisms papers, I found that it would be better to write about the "Hemispheric Magnetic Dichotomy" as many of the Martian Dynamo papers mentioned this content.
