In this study, we designed a new buoy type GPS drifter that is capable of measuring the rip current pattern in the surface layer particularly at Haeundae Beach, Korea. Our field test performance in August 2012 was successful using this new GPS drifter. Our GPS-tracked surf zone drifter can not only be easily affected by physical forces below the surface on the equipment's movement, but also unaffected by breaking waters. In this study, the design for a small, low-cost buoy type GPS drifter for collecting accurate Lagrangian data in the coastal zone is described.
