In the framework of a geophysical study to investigate the ice thickness on the Lobbia Glacier located in the Adamello Massif, Italy, we recorded 1393m of 2D multifold seismic data, in summer 1996, to constrain a joint 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 inciude band-pass filtering, f-k filtering, residual static corrections, stack, deconvolution and migration. The contact between the ice and the granite substratum appears as a strong reflection at a maximum two way time of 105 ms.
