Temperature and geographical dependence of the compressive and flexural strength of first-year sea ice
A modified relationship for the temperature dependence of the compressive strength of first-year sea ice, which included an additional Arrhenius term for temperature as well as the usual porosity term, was tested against all available data. The scatter was so large that no conclusion could be reache...
