Exploring the last of the ‘big five’ mass extinctions
The most recent mass extinction happened more than 60 million years ago during the the Cretaceous/Paleogene (K/Pg) boundary. This is the last of the ‘big five’ that occurred during the Phanerozoic (the current geological eon that began approximately 541 million years ago). The EU-funded EPROAMA project will shed light on the short to long-term effects of this event on the global environmental system, including the reestablishment of pre-extinction environmental conditions and marine biological productivity. For instance, how did primary productivity and the biological pump change and how did that impact the source and character of organic matter reaching the seafloor? The project will also study how these interlinked processes recovered after this extinction event.
