I find this usage less objectionable than the education jargon. It suggests that we all have a latent understanding of the turboencabulation principle just waiting for the right activity to force air into its ballast tanks and make it pop above the waves.

That said, I don't love this non-education jargon usage for its passive-voiced-ness. The letters didn't "surface" of their own accord. Somebody found them, decided that they were noteworthy, and made the choice to bring them into the public view.

Congratulation! You are a submarine!
