Field experiments on uniaxial compressive strength of sea ice in the Weddell Sea, Antarctica
The field experiments on Antarctic sea ice physical properties were performed in the Weddell Sea during the two Finnish Antarctic Expeditions (FINNARP-89/90 and -91192). Altogether 86 ice cores were drilled from 19 test sites including shorefast ice and pack ice floes. The temperature, salinity and...
