N2 - Recently, we established a blended-acquisition method: temporally signatured and/or modulated and spatially dispersed source array, namely S-/M-DSA, that jointly uses various signaturing and/or modulation in the time dimension and dispersed source array in the space dimension. Our S-/M-DSA method makes the blended-acquisition encoding and operations significantly simple and robust, as well as for the deblending processing. In this paper, we discuss how this method enhances the acquisition productivity, in addition to the deblending performance, both in the time and space dimension. This shows that S-/M-DSA enhances the acquisition productivity by decreasing the sweep length by a factor of the number of frequency bands in the time dimension, and decreasing the number of simultaneous shots using non-uniform, even-but-random and multi-scale sampling in the space dimension. This also reveals that S-DSA attains a best acquisition productivity whereas M-DSA attains a best deblending performance compared to conventional blending methods.
