Description:
Arecibo radar observations of Titan at 13-centimeter wavelength indicate that most of the echo power is in a diffusely scattered component but that a small specular component is present for about 75% of the subearth locations observed. These specular echoes have properties consistent with those expected for areas of liquid hydrocarbons. Knowledge of the areal extent and depth of any deposits of liquid hydrocarbons could strongly constrain the history of Titan's atmosphere and surface.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campbell, Donald B -- Black, Gregory J -- Carter, Lynn M -- Ostro, Steven J -- New York, N.Y. -- Science. 2003 Oct 17;302(5644):431-4.
