Wind, waves, and currents are forces known to affect the drift of ice floes in a wave field. This study focuses on the drift caused by wave forces only and will compare the simplified equation of motion for a single ice floe in a wave from R.R. Rumer, to a new equation derived from more complete work by J.N. Newman. This new equation takes into account that the added mass should only apply to the submerged portion of the floe and also adds the influence of added mass to the gravity force term. Floes of varying diameter and thickness and waves of varying length and amplitude were tested in a 56-meter wave flume at Dalian University of Technology. This data was used for input into the computer simulations. A three-dimensional discrete element model was used to compare the experimental data with both the new and old equations for floe motion.
