Abstract: Results from examinations of consolidation in three first·year ice ridges are presented, discussed and compared with results from the literature. The relationship between the thickness of the consolidated layer and the level ice thickness varied from l. 39 to 1.85. The estimated thickness of the consolidated zone depended on the method of investigation, the drillings included a partly consolidated layer and gave a thicker consolidated ZOne than the temperature measurements did. The measured growth of the consolidated layer did however not depend on the method of investigation. The consistency of the unconsolidated rubble was clearly different at the two sites. It was soft and slushy at Spitsbergen, and harder in the Gulf of Bothnia. Three possible reasons are discussed: surrOlmding currents, different shapes and the difference in salinity.
