Btw ...we like the tale in the book about Geological Society founder George Bellas Greenough and his occasional controversies. Prof Cheshire rates GBG for his pioneer importance to spreading geographic/geologic literacy through use of maps to convey useful information. An early Tharp & Heezen?

Prof Chesire recounts the Ocean Floor map story + others, in his just published, lavishly illustrated book that is getting rave reviews - it is recommended! Sneak preview here

And it is a credit to the early @geolsoc.bsky.social and Greenough that a riposte was made available to all. It undoubtedly diffused tension if not controversy. Debate was at the heart of the Geol Soc, as was the refereeing of papers with GBG the originator of this now ubiquitous academic practice!

It is worth adding context here - her account had not been endorsed by a naval officer, expected to be more trustworthy by dint of their conduct and scientific training, which included observational skills and duty to remain rational and calm in difficult circumstances (e.g. under fire).
