Electrical properties of sea ice at 0.1 to 30 Mc/s

This p aper sets forth th e d etails of an experi menta l prog ram in wh ieh th e re'sist ivitv and d ielectric cons~ant of Arctic sea icc were measured. Fourtee n icc samp le'S ra ng in g i n salJnl ty from 0.06 / % 0 (parts p er t housand ) to 23 % 0 by IVeightwerestud ieci. The valul's of r1 wlectnc co nstant and th e computed valu es of loss tangen t are' given as a fun ctio n of frequ ency (0.1 to 30 M c/s) for tC'mpe'rat ures f r ol~ -5C. to -40 C .
