In this study, we (myself, Kirsty Edgar, Tom Dunkley Jones, Carina Hoorn, Bridget Wade) analysed planktonic foraminifera from the Amazon Fan, where the Eocene-Oligocene sediments represent a rare low-latitude record of ecosystem change across the Greenhouse-Icehouse climate transition.
This pattern is replicated on the global scale, where we looked at the same assemblage dynamics using the Triton dataset.
In line with previous work, we invoke substantial changes in the thermal and nutrient structure of the global water column associated with the inception of the Antarctic ice sheet as the primary mechanism for these changes.
By assigning planktonic foraminifera to the functional ecological niche groups (ecogroups), we found that the assemblages in the western equatorial Atlantic exhibit a distinct turnover from communities dominated by warm-water dwellers to those dominated by cold-water dwellers.
Great opportunity here to study the Earth system during the often overlooked early Miocene. Application details here!

🚨New paper out with @alexauderset.bsky.social! We show that the Arabian Sea oxygen minimum zone (OMZ) was better oxygenated during the warm Miocene Climate Optimum than today, but its path to full deoxygenation was slow and complex.
