Studies were made of a 31.4 cm-long core of sea ice obtained from Elson Lagoon, Point Barrow, Alaska, to determine relationships between structural features readily observed in horizontal thin sections under low magnification. Important intercrystalline structural features ARE A SYSTEMATIC INCREASE IN CRYSTAL SIZE WITH DEPTH AND A FAIRLY CONSTANT 21 RATIO BETWEEN THE LENGTH AND WIDTH OF THE ICE CRYSTALS.
