Brief communication: Improved measurement of ice layer density in seasonal snowpacks

Abstract. The microstructure and density of ice layers in snowpacks is poorly quantified. Here we present a new field method for measuring the density of ice layers caused by melt or rain-on-snow events. The method was used on 87 ice layer samples taken from natural and artificial ice layers in the Canadian Arctic and mid-latitudes. Mean measured ice layer density was 909 ± 28 kg m⁻³ with a standard deviation of 23 kg m⁻³, significantly higher than values typically used in the literature.
