How does noise affect marine life?

SAES joins the commemoration of the International Noise Awareness Day, looking to raise awareness of the impact of underwater noise produced by human activity on marine flora and fauna, such as maritime transport and offshore wind farms building

Why are marine mammals closing to the coast? Recently, there are many news about unusual sighting of cetaceans on the Spanish coasts. This is because the human noise produced in the sea has drastically decreased due to COVID-19 confinement and travel restrictions, inviting whales and dolphins to get closer to the coast.

Human activity in the marine environment produces an increase in the level of acoustic noise in this sea, which affects the well-being of marine fauna. In fact, the European Marine Strategy Framework Directive (MSFD), aimed at achieving and maintaining Good Environmental Status in European seas, includes the regulation of noise emissions in descriptor 11.

SAES, as a specialists in underwater technology for 31 years, is researching in this area for years. The company has developed equipment for the measurement of underwater noise and has participated and participates in different programs and studies related to the measurement and analysis and modeling of the underwater sound propagation. Actually, SAES in consortium with partners organizations, is currently preparing a proposal for the call for European H2020 projects, focused on evaluating and mitigating the impact of noise emissions from ships on marine fauna.

underwater noise measurement

Some house-made equipment from the company, such as the SDH smart digital hydrophone or the MIRS underwater measurement station, are used to carry out

scientific and environmental studies, as well as to measure and study the underwater noise produced by industrial activity and ships on sea. Thus the noise can be controlled in order to reduce the impact on sea produced by various activities such as maritime traffic, building activities, extraction platforms and offshore wind farms.

SAES meets with Blue Growtht’s economic sectors at InnovAzul 2018

I International Meeting on Knowledge and Blue Growth, organized by the University of Cádiz (UCA) and the CEI-Mar Foundation.

InnovAzul 2018 took place in Cádiz on November 29 and 30. It is an international innovation meeting in the productive sectors of the Blue Economy, where more than 130 Naval and Offshore Construction companies and 600 specialists in this field.

The main objective of InnovAzul is the promotion of public-private competitiveness towards a circular economic model and sustainable development. InnovAzul is an essential meeting point for companies demanding technologies, administrations, knowledge generators and technological agents, for innovation and socio-economic development in the marine-maritime sectors.

B2B meetings.

Simultaneously, the attending firms were able to schedule up to 30 bilateral meetings with other participating companies related to their interests.

In this sense, SAES held meetings with universities and consulting companies in order to collaborate in environmental impact studies to require measurements and analysis of submarine noise. In addition, SAES provided information about the DDS to companies in the security sector and representatives of port authorities. It was also presented SOURCE-MAP systems, a tool for generation of noise maps, capable of evaluation of the radiated-noise by their facilities.

The wide participation in the event, more than a thousand attendees, gave the opportunity to SAES to communicate its capacity in tasks related to the measurement and estimation of underwater noise and the protection of critical infrastructures of submarine threats.
