AbstractMeasurements were made of the density of columnar-grained fresh water ice grown by a standard laboratory method and of single crystal ice. The procedure was to determine the weight of the ice in air and in an ice-saturated solution of triethylpentane using a calibrated electronic balance. The possible absolute error involved in the estimation of ice density was mainly attributable to the uncertainty in the value of the liquid density. This amounted to about 0.04 kgm[-3] for the effect of temperature. The possible total relative error was 0.20 kgm[-3]. There was no discernible difference between the densities of single-crystal and columnar-grained ice within the accuracy of the measurements. A density curve was established between temperature and density between 0 degrees C and -30 degrees C. Each point represents the mean value of 3 to 8 measurements. Scatter of the data at a given temperature was about plus or minus 0.17 kgm[-3] which was comparable to the estimated possible relative error of plus or minus -.20 kgm[-3].
