What is it about?
Broadband seismic favors great towing depth to preserve low frequency signals. However, greater towing depth means higher noise level. This paper discusses the normal modes theory and explore the field data.

Why is it important?
The findings in this paper are counteractive to the established knowledge that broadband seismic favors great towing depth. While gaining lower frequency signals, seismic data quality is compromised because of higher noise level . An optimal towing depth can be estimated by modeling to match the desired realistic frequency content and signal-to-noise ratio.
