And at Peter Island, the ice was thick, and there was very little
biological matter underneath.
Underneath a shallow lake, the bottom is soaked. If there are also ions,
conductivity should be good. Some ponds could have very deep layers of
humus. Wouldn't there be ions there? But I suspect a swamp is a better
bet than a pond.
All conjecture, of course. I have no measurements to back it up.
