Temperate ice

Alternative definitions (2), class: vernacular (0)
Term: Temperate ice
Definition: (1) Ice that contains a liquid phase of no more than moderate salinity with which it is in thermodynamic equilibrium at the solidliquid phase boundaries. (2) Less precisely, ice that is at its pressure-melting point. Other factors, notably the salinity of water inclusions, can be of comparable importance to the hydrostatic pressure for determination of the melting point. Sense 2 is adequate for simple purposes, but the details illuminated by Lliboutry (1971) and Harrison (1972) are likely to be of practical importance in detailed work.
