Magnetic Waves in the Martian Ionosphere

We present results from a wave analysis of MAVEN magnetometer data from 5-16 Hz and below 200 km. More than 40 signals of interest were found by using Fast Fourier Transform power spectra as guides and wavelet analysis as a follow-up tool. Many of the waves seem to be associated with the cusps of the crustal magnetic fields, while none are found within the strongest of crustal magnetic fields. We have determined these waves are not likely associated with field line resonances, lightning, or traveling ionospheric disturbances. Potential interpretations of these signals, their distribution, and their varying attributes are discussed.
