Why is sound important to ocean dwellers

Such as waves earthquakes, and sinking ships. Scientists have figured out how the noises that people make affect the lives of marine life What’s the trend? After the COVID-19 pandemic, the commercial shipping industry is recovering and is booming in 2023 . Large cargo ships directly harm the planet by emitting exhaust gases into the atmosphere. However, there is another negative consequence – sounds that disturb marine life. Graham Shannon, a British biologist from Bangor University in Wales, calls for attention to this. sunlight penetrates only a few hundred meters deep into the ocean. Therefore, the ability to make and recognize sounds is extremely important for deep-sea animals.

Man-made noise in the ocean is often

It helps to communicate navigate avoid danger Chile Phone Number List and search for food. For example, click shrimp from the western Atlantic Ocean can produce a loud clicking sound that can stun and kill prey. And blue whales emit low-frequency signals that can travel thousands of miles. How do people pollute the ocean with noise?  unintentionally produced by ships or infrastructure and industry, such as oil platforms. However, it can also be created on purpose. For example, many navies use sonars to locate ships and submarines. Geologists probe the seabed for oil and gas using seismic airguns.

The rumble of a seismic airgun can cause

The sounds produced by them can exceed 200 decibels BT Lists this value is deadly for humans. Noise travels four times faster in water than it does in air (at almost 1.5 km/s), so it can “travel” considerable distances. permanent hearing loss, tissue damage, and death in animals near it. In 2017, studies showed that a single shot from it resulted in an increase in zooplankton mortality from 18% to 40–60% in a 1.2 km section of the Pacific Ocean off the coast of southern Tasmania. The use of sonar has also resulted in mass stranding of several species of whales in Central America.
