The thermal conductivity and diffusivity of first year sea ice measured as a temperature depth profile in developing sea ice during the winter months in McMurdo Sound

The temperature depth profile was measured through the developing sea ice in McMurdo Sound with a 10cm resolution throughout the winter months until the spring to determine the thermal conductivity and thermal diffusivity of first year sea ice.

Measurements were recorded on a data logger every hour and every two weeks the logger was serviced and the data retrieved. The rate of growth of the sea ice throughout the season can be determined and together with the recorded thermal information can be used to provide a history of the formation of the sea ice.
