I am not in any way en expert, but I would have thought that the sea emits IR at a
low level, especially when compared to a human body. I would also have thought that
a block of dry ice would emit a tiny amount of IR, possibly not detectable with
current equipment. I would have thought that something like a low temperature
superconductor, when in superconductive state, would emit no IR. Is this so? Or
would something have to be at absolute zero to emit no IR?

Nope... they wouldn't be dead.. The sea, even if very cold still has an IR
Signature itself... Proof, add an ice cube, do IR detection magnification,
you can sea the cube as colder... Even colder dry ice will give you better
differentiation.

Ah , to throw the proverbial Monkey Wrench into the works
         Have you considered submergence in Water, Either Sea of Fresh?
        Since IR transmission in Water is minimal , Aquatic plants and
animals exist in the ambient temperature. ( trying to raise body temperature
in such a heat sink would be a tremendous energy cost )
        Since there is no discernible infrared signature from the aquatic
life,
          then by the logic would they not be considered dead?
