Oxygen depletion in ancient oceans caused major mass extinction – FSU EOAS Geology

Oxygen depletion in ancient oceans caused major mass extinction – FSU EOAS Geology

“Around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet. For years, scientists struggled to connect a mechanism to this mass extinction.

Geology Assistant professors Seth Young and Jeremy Owens and graduate student Chelsie Bowman from Florida State University‘s Department of Earth, Ocean & Atmospheric Science at FSU, part of the FSU College of Arts & Sciences, are now confirming what triggered this event.

Their study, published today in the journal Geology, resolves a longstanding paleoclimate mystery, and raises urgent concerns about the ruinous fate that could befall our modern oceans if well-established trends of deoxygenation persist and accelerate.”
