A recent American study warned of a wave of mass extinction of marine organisms currently living, due to the lack of oxygen in the oceans. The study, published yesterday in the journal Geology, revealed that the massive extinction wave that occurred 420 million years ago and that killed 23% of all marine animals on the planet was due to a lack of oxygen in the oceans, a similar situation. What is happening now.
Unlike other famous mass extinctions related to a meteoric landing or volcanic eruptions, no known destructive event has been causing the long extinction of 420 million. years, Lao-Kozloski extinction, making it one of the few extinguishing events. Similar to the significant reduction in biodiversity that occurs today, the window is important for studying future climate scenarios.
In researching the causes of this extinction, the University of Florida research team used advanced geochemical methods, including isotopic measurements of thallium, manganese concentration, and thallium. Sulfur isotopes on important sites in Latvia and Sweden, and scientists have been able to restore a schedule for the elimination of oxygen from the oceans for the Lao's extinction. – Kozlovsky.
The team's surprising new findings confirmed that the extinction record could be caused by a decrease in oxygen in the oceans, followed by more toxic and toxic oceanic conditions represented by the spread of the ocean. sulphide.
"This work is important because our observations of the modern ocean indicate a significant lack of oxygen that could put great pressure on organisms that require significant stress," says Jeremy Owens, Associate Professor, Department of Science. Earth, the ocean and the atmosphere in a report published by the University of Florida website. "Oxygen could be the first step toward the extinction of a number of other marine organisms." "There are important lessons to be learned from environmental crises in the distant past, and this study offers one of the most important lessons."
