AB: We present SHARAD investigation results on an extensive region of Mars near the equator that show evidence of shallow radio- transparent deposits. The first radar sounding data over this area was collected by MARSIS showing evidence of radio-transparency but we were not able to resolve the depth since the depth resolution of MARSIS is approximately 80 meters. SHARAD is able to resolve these deposits thanks to its higher bandwidth providing approximately 10 times better depth resolution. We have obtained observations with sufficient density to allow mapping the bed/deposit interface. Also, the reflection properties of the radio waves are analyzed to provide clues about the nature of the material filling the Elysium Planitia. Elysium Planitia is located east of the "Frozen Sea" region where is the focus of debate regarding its nature. The MARSIS radar sounder operates over 4 bands between 1.3 MHz and 5.5 MHz and has a maximum bandwidth of 1 MHz. SHARAD operates between 15 MHz and 25 MHz with a maximum bandwidth of 10 MHz.
