Frozen soils may be partially-bonded, poorly-bonded or friable, if the soil particles are held together (cemented) weakly by the ice. If ice bonding is strong, the soil is said to be well-bonded. The distinction between ice-bonded permafrost and permafrost that contains ice but in which the ice does not act as a cement, is particularly important in subsea permafrost, where the dissolved-solids content of the pore water affects the ability of ice to act as a cement. Acoustic geophysical methods can be used to delineate ice-bonded permafrost, but use of the term "acoustically-defined permafrost" is not recommended except as a modifier to describe the method used to determine the permafrost conditions.
