I like your article. Very relevant. The course you describe is the kind of course I'd have loved to be in as a student. I've never been a hardware guy, but one of the most fun experiences was as an undergrad in Italy do full A-Z filed acquisition, processing (some) and interpretation of gravity and greound magnetic data.
As a reviewer:
yes the link is broken as noted by @dabiged . Are there any resources you can point to, on your blog or podcast that talk about that course?
In the second paragraph you write: "...we should be very concerned about our data.": I am wondering if invested in would be better (less of a sense of worrying, and more about knowing about its every aspect).
Other than that thos two things for me it is ready to go.
Link in the article is broken http://tge.geoscience.tech/ is unresolved.
