Sorry to be a physicist (anal?!) about this :-) :-), but of course there is such a thing as water at 0 deg C. The thing we call "ice" produced in the following way: 1. Cool the water to *exactly* 0 deg C 2. The water cannot be cooled further without removal of latent heat of fusion (something like 80 kcal/g). 3. Once the latent heat of fusion is removed, you have "ice" at 0 deg C. This can then be cooled further, to a temp below 0 deg C. Simply: putting water in an environment with temp < 0 deg C results in the water cooling to 0 deg C, some time passing while the temperature remains at exactly 0 deg C, while the latent heat of fusion is removed (that is, ice is being formed), then further cooling of the solid ice.
