Towards a standard for vessel URN measurement in shallow water : applying acoustical propagation modelling to inform the design of a measurement program that determines if shallow water URN measurements can be comparable to those from deep water / authors: Michael A.

Includes bibliographical references (pages 47-48). "JASCO Applied Sciences, in collaboration with BC Ferries (BCF) and DW-ShipConsult, are executing a project sponsored by Transport Canada's Innovation Center (TC-IC) to provide results that will assist the International Standards Organization (ISO) in developing standard 17208-3 for the measurement of vessel underwater radiated noise (URN) in shallow water. Measurements in shallow water are difficult to perform because of the ways in which sound interacts with the seafloor and sea surface"--Background, page 1. Ships Noise.
