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.

Oceanographers used data from a pan-Arctic survey of carbon and trace elements to better understand how climate change will affect ecosystems in one of the fastest-warming regions of the world.
