Abstract :
A portable impedance measuring system and capacitive sensor array was developed to perform in situ measurements on sea ice. This equipment was installed close to McMurdo Sound in the Antarctic and measurements are currently being made during the southern winter and spring. These measurements are compared to measurements made on laboratory grown ice using a commercial impedance analyser. From these measurements information on the temporal and structural evolution of the ice can be obtained.
