In the framework of a geophysical study to investigate the ice thickness on the Lobbia Glacier located in the Adamello Massif, Italy, we recorded 1 393m of 2D multifold seismic data, in summer 1996, to constrain ajoint gravity survey covering an area of about 4 km2, Single fold seismic data (Tabacco, Pettinicchio, and Veronese 1995) , and gravity data (Olivier et al., 1996) , collected during previous surveys, provided an estimate of the maximum ice thickness. The main processing sequences
