Description: Research Report
Summary: The density of snow at any given depth does not change with time at Eismette (Greenland) because summer melting does not occur. The load of the overlying snow at any depth is equal to the density integrated over the depth. The time required for a snow particle to reach any depth is equal to the load divided by the accumulation in unit time. The vertical velocity is equal to the accumulation in unit time divided by the density. A formula for the specific velocity of densification is also derived. The measurements of density, weight of overlying snow, time elapsed since deposition, the vertical velocity and the rate of densification of the snow observed at Eismitte by Sorge for a depth of 15 m. accumulated over a period of 22 years show good correlation with the calculated values.
