This analysis yields\u03c11 = 104 \u03a9 m, 80 \u03a9 m, 45 \u03a9 m, and\u03c1p= 298 \u03a9 m, 230 \u03a9 m, 129 \u03a9 m for brine volumes\u03bdbof 40\u2030, 67\u2030, and 82\u2030 respectively. The observed dependence of\u03c11 on\u03bdbis used in conjunction with a mixing formula for the electrical resistivity of a two-phase heterogeneous system to arrive at values of \"average\" brine cell lengthslfor relatively warm sea ice. This treatment yieldsl\u2248 1.7 cm for 40\u2030\u2264\u03bdb\u226470\u2030 with a rapid extension of brine cell lengths for brine volumes abovec. 70\u2030.", "author": [ { "family": "G. W.
