The experimentally observed frequency dispersions of the complex dielectric coefficient for some samples of artificial saline ice (of a type similar to natural sea ice) are examined with a view to identifying major contributing mechanisms. The simultaneous integral equations describing the linear superposition of relaxation processes having a continuum of relaxation times were inverted numerically to yield histogram representations of the relaxation time distribution function between 10−9and 10−1sec. These functions exhibited three main features: (1) an abrupt peak near 10−9sec, responsible in part for the high frequency dispersion (above 1 MHz), and which is attributed to polarization of the elongated conductive brine cells within the ice (Maxwell‐Wagner‐Sillars dispersion); (2) a hump between 10−6and 10−4sec which shifts towards shorter relaxation times at higher temperatures, showing an activation energy similar to that of protons in pure ice—this mechanism is seen at midfrequencies (1 KHz‐1 MHz); and (3) a wide mass at longer relaxation times commencing between 10−4and 10−3sec which is probably associated with space‐charge polarization arising from movement of the ions within continuous brine channels reaching from one electrode to the other.
