1. A method for exploration of natural resources in a surveyed subsurface, the method comprising:
receiving the input seismic data d recorded in a first domain by seismic receivers that travel in water, the input seismic data d including pressure data and particle motion data;
generating a model p in a second domain, which is different from the first domain, to describe the input seismic data d;
processing the model p to generate an output seismic dataset with attenuated noise; and
generating an image of the surveyed subsurface based on the output seismic dataset with attenuated noise for locating the natural resources in the surveyed subsurface,
wherein
the generating of the model p includes computing the model p by solving an inverse problem based on an L transform.
