Duration: 1 hour

Description: The impacts of underwater sound on aquatic life have become a very important environmental issue. This is because many forms of marine life such as marine mammals and fish use sound as their primary mode of communication, navigation and in searching for prey. Activities generating underwater sound can affect these functions and, since sound can be far ranging, the spatial scale of impacts can be quite large as well. Regulators have picked up the issue and today several laws in Europe, the United States, and elsewhere aim, in general, to reduce or limit potential impacts of human activities on the marine environment.

Like many other activities, the dredging process produces underwater sound depending on the type of dredger, operation methods and so on. The knowledge about dredging induced sound and its effects has increased greatly in recent years and it grows by the day. After a brief introduction to the subject in this webinar participants will learn about:

• Effects of sound on marine life
• Dredging sound
• Documented impacts
• Management of sound impacts via mitigation measures

The presentation will build on the work of the WODA Expert Group on Underwater Sound.
 

Presenter: Dr. Frank Thomsen
Dr Thomsen is a Senior Marine Mammal and Underwater Sound Scientist at DHI in Denmark. He manages a variety of projects dealing with human impacts on the marine environment. He has extensive experience in conducting marine acoustics research, in advising regulatory bodies such as Defra, DECC (UK) and the BSH (Germany), and in provision of science for marine policy bodies such as OSPAR, the London Convention and ICES. His areas of expertise are acoustic communication in whales and dolphins, distribution and abundance of cetaceans, visual and acoustic marine mammal surveys, and effects of underwater noise on marine mammals and fish and environmental risk assessments. Dr. Thomsen chairs the WODA Expert Group Underwater Sound.

Special introductory offer: Attendance to this first CEDA webinar is free of charge; registration however, is required.
