volcanic eruptions,extinction of marine life

In a recent study, it was revealed that the climate change might have increased the levels of the atmospheric carbon dioxide and it is siphoning oxygen from today’s ocean which was occurring at an alarming rate.

The study was published in this week in the journal Proceedings of the National Academy of Sciences, as the researchers from Florida State University had done that they have found brings into the stark relief which is a disastrous effect and it is deoxygenated ocean could have a marine life.

Since a million of years ago, scientists have discovered the powerful volcanoes which are pumped into the Earth’s atmosphere which is full of carbon dioxide, and it drains the oceans of oxygen, and it drives a mass extinction of the marine organisms.

According to the co-author of the study, Jeremy Owens, who is an assistant professor in FSU’s Department of Earth, Atmospheric Science and Ocean said that we need to understand how volcanism occurs and how it can be related to modern anthropogenic carbon dioxide and it manifests itself in ocean chemistry and extinction events.

This study was carried by the group of international scientists who do this study in order to understand today’s oxygen-deprived oceans by investigating the Toarcian Oceanic Anoxic Event (T-OAE) which is in an interval of global oceanic deoxygenation and it was characterized by the mass extinction of marine organism which  can occur in the Early Jurassic Period. As per Theodore them, they wanted to reconstruct the Early Jurrasic Ocean oxygen levels to understand about the extinction more clearly and the T-OAE. Earlier, it was estimated that the ocean temperature and acidification as the main factor but it was released that oxygen change may be the thirds factor which might have caused this extinction and it is equally important.

We can still take steps to limit the oxygen loss in the modern oceans. It can be done by conserving important wetlands and estuaries, and it can help to blunt the effects of the harmful industrial emissions.
