Acoustics monitoring is important to understand the health of the coastal and underwater ecosystems. Human activities are threatening marine life by producing underwater noise pollution. Monitoring underwater noise allows us to detect the source of noise, reduce the impact, and protect the life of marine biodiversity.

Why Should I Care About Underwater Acoustics?

Underwater acoustics is important because sound travels much faster and farther in water than in air, making it an important means of communication and navigation for many marine species, such as whales, dolphins, and fish.

These animals use sound to locate food, communicate with each other, and navigate their environments.

Human activities, such as shipping, oil and gas exploration, and military sonar, can generate underwater noise that can interfere with these natural behaviors, potentially causing harm to marine life. This is called the anthropogenic sound.

By understanding underwater acoustics and the impacts of human-generated noise, we can work to minimize our impact on the marine environment and protect the health and well-being of marine species.

This can be achieved through better regulation of human activities in the ocean, the development of quieter technologies, and the establishment of protected areas where marine life can thrive without the interference of human-generated noise.

What Is Underwater Noise Monitoring?

Underwater noise pollution monitoring involves the measurement and analysis of underwater noise levels to assess their potential impacts on marine life and ecosystems.

This is done by deploying hydrophones, which are underwater microphones that can detect and record sound. These recordings can then be used to analyze noise levels, identify the sources of noise, and assess their potential impacts on marine species.

Underwater noise pollution monitoring is important for understanding the impacts of human activities on the marine environment and for informing decisions about ocean management and conservation.

By monitoring and reducing underwater noise pollution, we can help protect the health and well-being of marine life and maintain the integrity of marine ecosystems.

In addition to identifying specific sources of noise pollution, underwater noise monitoring can also help us understand the cumulative effects of multiple sources of noise on marine life.
