Anti‐Phased Miocene Ice Volume and CO2 Changes by Transient Antarctic Ice Sheet Variability
(Paleoceanography and Paleoclimatology, 2020-11-24)Geological evidence indicates large continental‐scale Antarctic ice volume variations during the early and mid‐Miocene. On million‐year timescales, these variations can largely be explained by equilibrium Antarctic ice ... -
Effects of CO2 and Ocean Mixing on Miocene and Pliocene Temperature Gradients
(Paleoceanography and Paleoclimatology, 2022-02-11)Cenozoic climate changes have been linked to tectonic activity and variations in atmospheric CO2 concentrations. Here, we present Miocene and Pliocene sensitivity experiments performed with the climate model COSMOS. The ... -
Late Oligocene—Early Miocene shortening in the Thrace Basin, northern Aegean
(International Journal of Earth Sciences, 2021-05-15)Late Cenozoic was a period of large-scale extension in the Aegean. The extension is mainly recorded in the metamorphic core complexes with little data from the sedimentary sequences. The exception is the Thrace Basin in ... -
Miocene age of the Huanan basalt lava flow (NE China) inferred by reset of zircon (U–Th)/He thermochronometer in the underlying sand
(Geological Journal, 2020)Mafic lavas of Cenozoic age are widely distributed in northeast China and received much attention as an important part of the Circum-Pacific volcanic belt. The age constraints for the volcanic activity were determined ... -
Provenance and Weathering of Clays Delivered to the Bay of Bengal During the Middle Miocene: Linkages to Tectonics and Monsoonal Climate
(Paleoceanography and Paleoclimatology, 2021-02-24)Tectonics and regional monsoon strength control weathering and erosion regimes of the watersheds feeding into the Bay of Bengal, which are important contributors to global climate evolution via carbon cycle feedbacks. The ... -
Simulated Thermohaline Fingerprints in Response to Different Greenland-Scotland Ridge and Fram Strait Subsidence Histories
(Paleoceanography and Paleoclimatology, 2020)Changes in ocean gateway configuration can induce basin-scale rearrangements in ocean current characteristics. However, there is large uncertainty in the relative timing of the Oligocene/Miocene subsidence histories of the ... -
The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures
(Paleoceanography and Paleoclimatology, 2023-02-07)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 warm Miocene climate and pronounced polar warmth at ...
