The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures

A Hossain, G Knorr, W Jokat… - Paleoceanography …, 2023 - Wiley Online Library
Based on inferences from proxy records the Miocene (23.03–5.33 Ma) was a time of
amplified polar warmth compared to today. However, it remains a challenge to simulate a …

Late Eocene record of hydrology and temperature from Prydz Bay, East Antarctica

EJ Tibbett, HD Scher, S Warny… - Paleoceanography …, 2021 - Wiley Online Library
Abstract The Eocene‐Oligocene transition (EOT) marks the onset of Antarctic glaciation at
33.7 Ma. Although the benthic oxygen isotope record defines the major continental ice sheet …

Deep water inflow slowed offshore expansion of the West Antarctic Ice Sheet at the Eocene-Oligocene transition

G Uenzelmann-Neben, K Gohl, K Hochmuth… - … Earth & Environment, 2022 - nature.com
The stability of the West Antarctic Ice Sheet is threatened by the incursion of warm
Circumpolar Deepwater which flows southwards via cross-shelf troughs towards the coast …

Enhanced terrestrial carbon export from East Antarctica during the early Eocene

GN Inglis, JL Toney, J Zhu, CJ Poulsen… - Paleoceanography …, 2022 - Wiley Online Library
Terrestrial organic carbon (TerrOC) acts as an important CO2 sink when transported via
rivers to the ocean and sequestered in coastal marine sediments. This mechanism might …

Competing influences of the ocean, atmosphere and solid earth on transient Miocene Antarctic ice sheet variability

LB Stap, CJ Berends, MDW Scherrenberg… - The Cryosphere …, 2021 - tc.copernicus.org
Benthic δ 18 O levels vary strongly during the warmer-than-modern early-and mid-Miocene
(23 to 14 Myr ago), suggesting a dynamic Antarctic ice sheet (AIS). So far, however, realistic …
