Properties of Decaying First Year Sea Ice: Two Seasons of Field of Field Measurements.

This paper reports on two seasons of field measurements conducted on landfast, first year sea ice in the Canadian Arctic. Field measurements began in mid-May, when the ice was still cold and continued, on a regular basis, until June and July. During the field programs the snow and ice thickness were monitored, as were the ice temperature, salinity and strength of the ice. The in situ ice borehole strength was measured in more than 100 borehole jack tests each season. Measured borehole strength was compared to the calculated flexural strength of the ice. During the period that the strengths overlapped, there was good agreement between trends in the measured ice borehole strength and the calculated flexural strength.NRC publication: Ye
