Model Results Information:
The model results are from the bubbly ice densification model of Salamatin and Lipenkov (see references). The model was applied to 6 different close-off depths (40-65 m), using measured RICE porosity as a tuning parameter, to model the pressure increase in bubbles at depth.
All model parameters can be found in the model output text files for the 6 different model runs. They are described in detail in the references.
Output parametres:
h: Depth [m]
C: Porosity []
Ccal: Modeled porosity []
Pb: Mean Bubble Pressure [MPa]
Pbcal: Mean Bubble Pressure Modeled [MPa]
Pi: Averaged pressure in the ice matrix [MPa]
Age: ice age [kyr]
