Description: Technical Report
Summary: The strength of sea ice was studied at McMurdo, Antarctica during two successive field seasons. Three hundred tensile tests were made on continuous core samples taken at various locations on ice aged 1 year, 2 years and more than 5 years. Salinity profiles were obtained for each core. A relationship between strength (kg/cm^2) and volume of brine cavities (per cent), as suggested by Assur, adequately represents the data for brine volumes less than 0.44 : strength equals 29.1 - 48.0 times the square root of the volume. The constants agree satisfactorily with values obtained previously for Arctic sea ice, the value for the strength of very low brine volume approaching the value for fresh-water ice. The model on which the above expression is based apparently breaks down at high brine volumes.
