1. A method for seismic surveying, comprising:
deploying a plurality of seismic receivers proximate an area of subsurface to be surveyed;
moving at least one seismic energy source in a path that circumscribes a center, wherein positions of the plurality of seismic receivers remain fixed;
wherein a distance between the path and the center changes continuously and monotonically as the at least one seismic energy source traverses the path;
actuating the at least one seismic energy source at selected times as the at least one seismic energy source traverses the path, wherein a spacing between positions of the at least one seismic energy source along the source path and transverse to the source path varies between successive actuations of the at least one seismic energy source; and
detecting seismic energy at the plurality of seismic receivers resulting from actuating the at least one seismic energy source.
