Content SummaryThe preliminary results of a new proposed technique for the data acquisition of the 2D MASW method is discussed in this extended abstract. This technique aims at increasing the fieldwork productivity of the 2D MASW data acquisition significantly. It is estimated that this technique may increase the productivity of the filed work of more than 70% than the traditional land-streamer towed by truck technique. The basic idea is to perform two 2D MASW profiles simultaneously for each run of the truck, employing two land streamers, two seismic recording instruments, but only one seismic source for both receiver arrays, located in the middle of the two profiles. This work aims to investigate the applicability of the proposed acquisition technique and the accuracy of the acquired data, using real data taken from two different sites as well as synthetic seismic data. The dispersion curves and S-wave profile comparison between the traditional and the proposed technique for the real and synthetic data was found to be quite encouraging. The proposed technique manages to reproduce the S-wave profiles resulted from the conventional MASW deployment, in the framework of an acceptable, for the engineers, error. Further basic research concerning the MASW-DS assumptions is considered necessary.en
