Abstract : 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 sigma (kg/sq cm) and volume of brine cavities v (%0), as suggested by Assur, adequately represents the data for brine volumes less than 0.400: sigma = 29.1 - 48.0 v to the 1/2 power. The constants agree satisfactorily with values obtained previously for Arctic sea ice, the value of sigma for 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. (Author)
