    <subfield code="a">AbstractThe results of 66 Schlumberger geoelectric soundings on first-year sea ice are analysed to obtain average values of d.c. electrical resistivity both parallelρ1 and perpendicularρpto the long brine cell direction. This analysis yieldsρ1 = 104 Ω m, 80 Ω m, 45 Ω m, andρp= 298 Ω m, 230 Ω m, 129 Ω m for brine volumesνbof 40‰, 67‰, and 82‰ respectively. The observed dependence ofρ1 onνbis 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≈ 1.7 cm for 40‰≤νb≤70‰ with a rapid extension of brine cell lengths for brine volumes abovec. 70‰.</subfield>
