Ice growth and oceanic heat flux: models and measurements / Anders Omstedt, J.S. Wettlaufer.

Title: Ice growth and oceanic heat flux: models and measurements / Anders Omstedt, J.S. Wettlaufer.
Author(s): Omstedt, Anders.
Wettlaufer, J. S.
Date: 1992.
In: Journal of Geophysical Research. (1992.), Vol. 97(C6) (1992)
Abstract: Heat fluxes at ice--ocean interface and ice thickness were investigated by comparing field data from drift experiments with model calculations. Calculations are based on two types of models: one-dimensional ice--ocean model with high vertical resolution, and simple one-dimensional bulk heat transfer model. These models predict ocean heat fluxes that are quite variable in time owing to short-term variations in ice drift. Both calculate realistic ice thicknesses. Demonstrates that observed time variation in ice thickness from eight experimental sites with varying initial thicknesses and bottom topographies can be reproduced by applying bulk heat transfer coefficients in range (2.8±1)x10⁻⁴.
