Short summary
A study in the equatorial Atlantic Ocean (Ocean Drilling Program Site 1260) reveals the deep-sea biotic response to a middle Eocene warming event 41.52 million years ago. Low-diversity benthic foraminiferal assemblages indicate environmental stress during the warming event. We argue that the biotic response in the deep sea and carbonate dissolution at this site were likely related to its paleoceanographic setting.

Short summary
The Paleocene–Eocene Thermal Maximum (PETM) is the closest geological analog to modern anthropogenic CO2 emissions, but its causes and the responses remain enigmatic. Coastal plain sediments can resolve this uncertainty, but their discontinuous nature requires numerous sites to constrain events. Workshop participants identified 10 drill sites that target the PETM and other interesting intervals. Our post-drilling research will provide valuable insights into Earth system responses.

This paper examines benthic foraminifera, single-celled organisms, at Integrated Ocean Drilling Program Site U1506 in the Tasman Sea from the Late Miocene to the Early Pliocene (between 7.4 to 4.5 million years ago). We described and illustrated the 36 most common species; analysed the past ocean depth of the site; and investigated the environmental conditions at the seafloor during the Biogenic Bloom phenomenon, a global phase of high marine primary productivity.

We generated high-resolution records of carbonate accumulation rate from the Miocene to the Quaternary in the tropical Atlantic Ocean to characterize the variability in pelagic carbonate production during warm climates. It follows orbital cycles, responding to local changes in tropical conditions, as well as to long-term shifts in climate and ocean chemistry. These changes were sufficiently large to play a role in the carbon cycle and global climate evolution.

This study attempts to gain a better understanding of the marine biological carbon pump and ecosystem functioning under warmer-than-today conditions. Our records from marine sediments show the Pacific tropical marine biological carbon pump was driven by variations in seasonal insolation in the tropics during the Late Cretaceous and may play a key role in modulating climate and the carbon cycle globally in the future.

Short summary
We use the first high-resolution southeast Atlantic carbonate record to see how climate dynamics evolved since 30 million years ago (Ma). During ~ 30–13 Ma, eccentricity (orbital circularity) paced carbonate deposition. After the mid-Miocene Climate Transition (~ 14 Ma), precession (Earth's tilt direction) increasingly drove carbonate variability. In the latest Miocene (~ 8 Ma), obliquity (Earth's tilt) pacing appeared, signalling increasing high-latitude influence.

Short summary
The Gulf Stream plays a crucial role in the ocean stability and climate regulation of the Northern Hemisphere. By analysing the fossil microorganisms that lived in the water column and the ocean floor, as well as reconstructing the ancient ocean's biogeochemistry, we were able to trace longitudinal shifts in the Gulf Stream during the late Eocene (36 Ma). Our results provide insight into the Gulf Stream's behaviour and the NW Atlantic's palaeoceanography during the Late Eocene (ca. 36 Ma).
The Gulf Stream plays a crucial role in the ocean stability and climate regulation of the...
