The High Tech Seal CTD Hats


The standard issue tool for the oceanographer at sea is the Conductivity, Temperature, and Depth instrument (or CTD).

This work is expensive, requiring a properly outfitted ship and crew. But what if you could get a decidedly low-tech piece of equipment to do most of the work for you?

Researchers in the Southern Ocean near Antarctica (and elsewhere) have developed a sealCTD—a (small) CTD instrument strapped to a seal, which then gathers data that is otherwise quite hard to come by.


As user Boskone eloquently noted in the article comments, the seals must be saying to themselves some variant of: “Fuckin’ two-legged things. Net our fish, club us to death, and now they’re gluing shit to my head. We really gotta get our space program off the ground.”

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
