Strength–temperature equations for first-year ice, second-year ice, and two categories of multi-year ice
Strength–temperature equations are presented for four categories of sea ice based on the borehole strengths (BHS) measured during 876 tests in 162 boreholes and their corresponding ice temperatures. The strength of every type of sea ice decreases with increasing ice temperature, as expected. The mor...

Strength–temperature equations are presented for four categories of sea ice based on the borehole strengths (BHS) measured during 876 tests in 162 boreholes and their corresponding ice temperatures.

Equations based on ice temperature provide a reasonable prediction of the BHS for the different sea ice categories, but they cannot reproduce the measured strengths exactly.
