Abstract

The field experiments on Antarctic sea ice physical properties were performed in the Weddell Sea during the Finnish Antarctic Expedition in 1989-1990. The examined ice included shorefast ice and pack ice floes. Altogether 61 ice cores were drilled from 12 test sites. The temperature, salinity and density distributions in the ice cores were measured. Ice thin sections were prepared and photographed through crossed polaroids to study the structural characteristics of Antarctic sea ice. The unconfmed uniaxial compressive strength of ice was tested with 165 samples in the ambient temperatures of the examined ice floes. The tests were made in the brittle range with high stra
