I would like to know more about these different types of ice that have been mentioned in the ice skating discussion. Are they different crystalline forms of H2O? Please endeavor to give a reference in the literature so that I can decide this for myself.

The different forms of ice are allotropes formed by subjecting ordinary ice
(ice I) to high pressure; most have specific gravities greater than 1 (i.e.
they would sink in water).
A handy reference is the McGraw-Hill Encyclopedia of Science and Technology,
under the heading "water".

I don't know about ice 1 or ice 2, but there is a very interesting
story surrounding ice 9 - Kurt Vonnegut's Cat's Cradle. Ice 9's
crystalization structure is stable throughout the spectrum of temperatures
we experience here on Earth. When, towards the end of the story, the
ice 9 is dumped into the ocean, (you guessed it) the crystal fed upon
itself and froze every drop of water in the world. A rather interesting
concept.

Can Ice 9 exist at reasonable pressures?

Yes, of course Ice 9 can exist under reasonable pressures. For example, I read Cat's Cradle while on summer vacation - I was under no pressure at all. An interesting way to commit suicide: touch a crystal of Ice 9 to your tongue. Drew

"Cat's Cradle" by Kurt Vonnegut, Jr. introduces "ICE 9" and its final effect on everything.
