This paper presents updated distributions of the temperatures, salinities and borehole strengths of old ice, as a function of time of year. Thousands of measurements are compiled from old ice floes across the Arctic. Probability of exceedance curves are used to show the more ‘extreme’ values that can occur at various depths in the ice, whereas properties over the full ice thickness are obtained from (i) the means of populations and (ii) by depth-averaging measurements from the same borehole.
