In recent years, there have been new suggestions for recovering surface wave from underwater pressure transducer, such as the ones by Kuo and Chiu (1994) and Hashimoto et al. (1997). This study compared these methods with the widely used pressure transfer function from linear wave theory, using field data measured by an ultrasonic wave gauge. From the measured data it was found that the two new methods did not improve the accuracy on the surface wave reconstruction.
