OCEANOISE is pleased to introduce the reports of the technical sessions held in 2015.

The OCEANOISE2015 Science Committee would like to warmly thank all session chairs who have made possible this very relevant publication, as well as all the speakers who have contributed to their edition.

These reports represent the essence of the debates around the state-of-the-art in the field of ocean noise as well as the identification of the remaining questions to be addressed in the future.

Bi-annually publishing these reports, after each edition of OCEANOISE, will allow tracking the advances in the different domains of application of underwater noise, and from a broad perspective: academia, industry, regulation and NGOs.

The clear intention here is to consolidate a necessary multi-disciplinary approach towards a better understanding and integration of solutions that may help exploring and exploiting the ocean in the future, with environmentally responsible protocols and tools.
