Abstract

In 2008, students of the University of Southern Mississippi surveyed a portion of the Pearl River. Due to the ultra-shallow nature of the survey area, a multibeam mount was constructed that tilted the transducer 35o to the side with respect to nadir. Such an orientation had predicted gains of 60% in the center of the channel and facilitated the collection of data further inshore than otherwise possible. To compensate for excessive outer beam noise, a CUBE surface filtering regime was adopted. Crosscheck analysis showed the acquired data easily met IHO S-44 1a standards. This paper details the evaluation and results of such a non-traditional mount.
