Within Task 2.2 of the SATURN project, our partners at TSI -Técnicas y Servicios de Ingeniería S.L., TNO, JASCO Applied Sciences collaborated with the National Physical Laboratory to develop a research paper for the Journal of the Acoustical Society of America, where a new method to obtain propagation loss in shallow water is presented.

This method known as the smoothed semi-coherent image method (SSCI), is based on the seabed critical angle. The SSCI method has been implemented in the upcoming ISO 17208-3 standard, which is the ongoing ISO standard to measure URN from vessels in shallow water (expected to be issued in summer this year).

This paper is also accompanied by additional material, which you can download below:

• Full mathematical derivation of the method

• Excel spreadsheet to easily compute propagation loss under the SSCI method

• Measured underwater sound in the SATURN project used to validate the method (in form of sound pressure levels)
