Mono-channel recording systems with a Boomer seismic source are very cheap and can be easily deployed in sensitive environments such as lagoons or busy harbors ( Zecchin et al. 2008 ). The price paid for these advantages is the lack of signal redundancy typical of multi-channel records, which makes it possible to estimate wave propagation velocity and angle-dependent reflectivity, and to improve the signal-to-noise ratio by stacking or migration. In this paper, we show that some of this information can be obtained by inverting the amplitudes and traveltimes of shallow primary reflections and their multiples, using a single offset in a Boomer survey.
