The forces which cause ice to move are provided by wind stress and water currents. In the present study the relationships between the movement of the surfaces occupied by comparatively thin ice-floes mostly in contact (so-called close ice-area) and the surface layer current and surface wind velocity are discussed at first and then a simple and easy method for forecasting the ice-area movement are presented using these relationships. Finally, the utility of this forecasting method is tested by applying it to actual examples on the coast of East-Hokkaido on February 1955.
