Underwater noise

The impact of underwater noise has aroused increasing attention in recent years. The Marine Directive 2008/56 / CE and the Marine Strategies are a great step forward in preserving marine biodiversity from anthropogenic levels that can adversely affect them..

Our work

Programme design

We have realized programs and follow-up of submarine noise (D11) for the marine strategies.

Advice to research centers

We are an international reference in the field of underwater noise (D11)

Calculation of indicators

We have participated in the definition of the indicators for impulsive sound and continuous sound.

Development of algorithms

We have programmed software for the detection of cetaceans according to D11 (detectors of whistles, clicks and low frequency tones)

Processing and interpretation of data

We elaborate studies of environmental impact of the underwater noise in works of installation of submarine cables, dredgings and construction of ports.
