We have measured signals induced in 5 Corbino electrodes by spontaneous\noscillations of 2D surface electrons on liquid helium at \∼0.3 ,K, with a\nperpendicular magnetic field and microwave radiation. Analysis using\nmulti-scale, time-resolved, methods yields results consistent with\nmagnetoplasmons modulated by slow surface gravity waves, with the latter\nrequiring consideration of the 3rd dimension. Calculation of phase differences\nand phase coherences between signals from differently-positioned pairs of\nelectrodes enables reconstruction of the electron dynamics on the helium\nsurface.\n
