| Abstract: | Investigation of seabed micro-topography with the acoustic deep-tow system in a seamount of the Marcus-Wake ridge area was carried out successfully for the first time in China during the DY115-21 cruise of 2009.In this paper,the composition and working principle of deep-tow system are introduced,and post-processing of the synchronous survey data of multi-beam and side scan sonar is illuminated.In addition,the micro-topography of the survey area is analyzed and the caution is discussed selectively.According ... |
