Record #162264:

Modeling the high-frequency component of Arctic sea ice drift and deformation / Petra Heil, William D. Hibler, III.

Title: Modeling the high-frequency component of Arctic sea ice drift and deformation / Petra Heil, William D. Hibler, III.
Author(s): Heil, Petra.
Hibler, William D.,
Date: 2002.
In: Journal of Physical Oceanography. (2002.), Vol. 32(11) (2002)
Abstract: Presents dynamic-thermodynamic sea-ice model that includes "inertial embedding" of sea ice into oceanic boundary layer to reproduce sea-ice motion and deformation at daily and sub-daily frequencies. Comparison with data from buoy observations shows this model simulates sea ice motion more successfully in regard to high-frequency component. Model gives deformation variability and net sea-ice divergence when high-frequency motion is simulated, and this must be included to describe sea-ice evolution completely. As sea-ice grows more in open water than basal growth under thick ice, brief opening and closing of ice due to inertial or tidal motion increases growth rate significantly compared to basal-only ice growth, perhaps by 20%.
