Abstract: Let L be an alternating link in S3 and let L project on S2 except near crossings of L where L lies on a bubble. If the projective diagram on S2 has n crossings, then there are n bubbles. Thus are construced 2-spheres surfaces S2+ and S2- by the properties of the link. Let F be an incompressible and pairwise incompressible surface in S3-L, there is a collection of simple closed curves when the surface F is in a standard position. The surfaces are described by discussing the properties of F∩S2±. The genus of the surface equals zero if the graph of F∩S2± is special simple.
Key words: alternating link, genus, incompressible surface
