Underwater Noise Concerns: How Can the Maritime Industry React?

_ In addition to pressure to improve energy efficiency, the maritime industry may soon face demands to reduce underwater noise from shipping. This is illustrated by a large number of studies being reviewed by UN panels to bring clarity to the subject. In this paper, the studies relevant to shipping and shipbuilding are reviewed. From this review the progress of the consultative process, possible shortcomings, and potential collaborative actions beneficial to the marine industry are identified. Key revelations include inconsistencies in the way the scientific community represents shipping noise and areas where more focus is needed to ensure resilience. Furthermore, several future research focus topics are suggested in order to address these issues. This paper does not argue for or against underwater noise being viewed as harmful to marine life; it only serves to review the current consultative process and how the maritime industry could benefit from participating.
