Developing human activity at sea opens up new possibilities for the global economy, but increases environmental pressures. However, developing use of the sea in harmony with marine ecosystems is a major challenge. Quiet-Oceans meets that challenge by providing manufacturers, environmental research consultancies, public bodies and marine mammal protection organizations, with solutions for ocean noise forecasting, monitoring and reducing anthropogenic noise impact. Quiet-Oceans works in partnership with the research community to help understanding the impact of underwater anthropogenic noise on aquatic life.
