ACCOUNTING FOR SEA FLOOR PROPERTIES IN THE ASSESSMENT OF UNDERWATER NOISE RADIATED FROM SHIPS IN SHALLOW WATER

Publikováno v: ICUA2020.

To minimize the impact of human activities on marine fauna, efforts need to be taken to reduce underwater noise due to shipping by first defining procedures to measure radiated noise from ships. The signal received by a hydrophone array placed in the

Influence of the measurement configuration for the assessment of underwater noise radiated from ships in shallow water

Autor: Valentin Meyer, Christian Audoly

Publikováno v: OCEANS 2019 - Marseille.

In the context of the increase of human activities in coastal areas, awareness of the impact on marine mammals has risen. Following the Maritime Strategy Framework Directive of the European Union in 2008, actions have been undertaken to achieve good
