Abstract: Multibeam echosounder technology plays an important role in underwater topographic survey, and this technology has been used in ocean and inland water survey.This paper presents the basic components and performance of the EM2040C multibeam echosounder system and introduces its application in the monitoring of sea sand resources. The quantitative monitoring techniques and data processing progress has also been discussed. The research results show that the EM2040C multibeam echosounder system can quickly and efficiently obtain the sea floor terrain data. The results can meet the requirements of the relevant specifications and the EM2040C multibeam echosounder system can be widely applied in the quantitative monitoring of sea sand mining.

Key words: EM2040C multibeam echosounder system, sea sand mining, quantitative monitoring, underwater topography
