Differential Sea Ice Drift
Abstract
The development of an accurate predictive model for the motion and deformation of arctic pack ice is believed by most engineers and scientists concerned with arctic research and development to be of prime importance both for practical operational purposes and for climatological considerations. The report, divided into two parts, describes the analysis of the 1972 results. Part I examines the results with a view toward understanding of the nature of the ice velocity field and determining the minimum scale on which the pack ice may be viewed as a continuum. Part II represents the formulation of an analytic solution of a linear drift model which includes ocean, air and Coriolis forces and models the ice as a viscoelastic medium. The predicted results of this calculation (based on meteorological variables) are compared with observed differential drift measurements with good agreement and a number of conclusions regarding ice drift calculations using a linear model are drawn.
