Just as public life has been paralyzed by the epidemic of coronavirus, so has the seafloor been quiet. After a team of oceanographers studied the silence of the ocean, they named the period “the year of the calm sea.”
According to a BBC report, the researchers planned to hear the sound under the sea before and after the lockdown. They have identified the sound from two hundred ocean hydrophones. A hydrophone is a type of microphone used to hear sound under the sea.
Peter Lock, a professor at the University of St Andrews, said: “Lockdown has slowed global goods displacement. Otherwise, it would not have been possible.
“We planned to measure the change in sound using hydrophones and find out how it affects aquatic life. It’s just as people can hear more birds chirping or see more wildlife in the environment as traffic noise decreases.”
The seas are suffering greatly as a result of pollution and global warming. It also has the impact of excessive sounds. But Professor Tak thinks it is relatively easy to reduce the noise.
Jennifer Myxis-Olds, a professor at the University of New Hampshire and an oceanographer, thinks the study will shed light on submarine noise pollution as well as many more subtle issues.
“We can learn a lot from the sound of the ocean,” he said. “My goal is to create a map of the global ocean soundscape where you can hear the sound of a ship’s route, get an idea of the pattern of whales moving from one place to another. The sound of small icebergs can also tell you about climate change. “
An article published in the journal Science says that in recent years noise has been rising under the sea for shipbuilding, military activities, and the use of oil and gas, which is affecting aquatic life.
Marine natural sounds help aquatic animals in many ways, said Professor Tack. Explaining its role, he further said that where the fish larvae have to go and live is exactly from the sound of the coral wall. So everyone should pay attention to reduce the noise under the sea.
