Thank you for making this video.

The susceptibility of fresh water is zero and that of sea water is also zero. So, I don't think that magnetic surveying will work under sea water. @ David Deutsch

Love it

Hi! Thank you for making this video. It's very interesting. But I can't find the answer to a question on magnetic surveying. Does magnetic surveying work on marine landscapes? Underwater? Under sea water? How deep underwater does it work? Any advice would be great. Thanks!
