TitleA device for measuring wave-induced motion of ice floes in the Antarctic marginal ice zoneAbstractA series of wave instruments was deployed on first-year Antarctic sea ice during SIPEX (Sea Ice Physics and Ecosystem Experiment) II. Here we describe the hardware and software design of these instruments and give an overview of the returned dataset. Each instrument consisted of a highresolution accelerometer coupled with a tri-axis inertial measurement unit, which was located using GPS. The significant wave heights measured near the ice edge were predominately between 1 and 2 m. During the 6 weeks of data capture, several large wave events were measured. We report here a selection of events, highlighting the complexities associated with measuring wave decay at individual frequencies.AcknowledgementsWe thank M. Doble, V. Squire and T. Haskell for contributions toward instrument design; T. Toyota for providing the ice-floe size and ice-thickness data; and the captain and crew of RV Aurora Australis for their assistance in deploying the waves-in-ice instruments.
