Summary: Concurrent measurements of ice growth and ice-surface temperatures made at Eureaka (N.W.T.) during the 2 seasons 1949-1951 were used to compute a composite numerical value for 3 physical properties of sea ice - thermal conductivity 𝗄, latent heat of fusion 𝖫, and density ρ combined as 𝗄/𝖫ρ. Values for this expression were found to: 1.) increase from approximately 4.7-7.0/100,000 during ice growth from 0.6-1.0 m thickness (Nov. 6 - Dec. 22); 2.) range from 7.0 8.0/100,00 during ice growth from 1.1-1.3 thickness (Jan. 20 - Feb. 10); 3.) decrease slightly during the remaining growth period. These variations may be considered as due to changes in the effective conductivity related to physical changes and brine distribution in sea ice. A near linear relationship was found between mean daily ice accretion and sea-ice temp gradient.
