This paper extends the study on reflection and refraction of waves at the interface of water and porous sea ice by Yew and Weng [J. Acoust. Soc. Am.82, 342–353 (1987)]. The behavior of leaky Rayleigh waves and Scholte waves generated by a line cylindrical wave source at a distance below the interface is analyzed. It is demonstrated that a wave receiver in the water would pick up a direct wave from the source, a specularly reflected wave from the interface, a leaky Rayleigh wave, and, if the source and receiver are close to the interface and to each other, a Scholte wave. The effects of porosity and frequency on the behavior of these surface and interface waves are also studied. PACS numbers: 43.30.Ma
