researchers present new evidence that the deoxygenation of the ocean wiped out biodiversity during one of the “big five” mass extinctions in earth’s history – relevant information as climate change contributes to decreasing oxygen in the oceans today.
when significant oxygen entered the atmosphere, ancient life multiplied. but after a few hundred million years, earth’s oxygen plummeted, resulting in a die-off likely greater than the extinction of the dinosaurs.
stanford earth's david lobell, rob jackson, erik sperling, dustin schroeder, sally benson, roz naylor, michael machala, rosemary knight and kate maher have received funding for interdisciplinary research to solve major environmental problems.
why did the first big, complex organisms spring to life in deep, dark oceans where food was scarce? a new study finds great depths provided a stable, life-sustaining refuge from wild temperature swings in the shallows.
