Eocene Shark Teeth From Peninsular Antarctica: Windows to Habitat Use and Paleoceanography [0.03%]
南极半岛地区古新世鼠鲨牙齿化石:栖息地利用和古海洋学研究窗口
Gabriele Larocca Conte,Adam Aleksinski,Ashley Liao et al.
Gabriele Larocca Conte et al.
Eocene climate cooling, driven by the falling pCO2 and tectonic changes in the Southern Ocean, impacted marine ecosystems. Sharks in high-latitude oceans, sensitive to these changes, offer insights into both environmental shifts and biologi...
Biogeochemical Traits of a High Latitude South Pacific Ocean Calcareous Nannoplankton Community During the Oligocene [0.03%]

Early Eocene (∼56-48 Ma) climates are useful to investigate polar climate dynamics in the absence of ice. We explore early Eocene orbital variability of Arctic climate using sediments recovered by the Arctic Coring Expedition (ACEX). High ...
Seasonal Variations in Triple Oxygen Isotope Ratios of Precipitation in the Western and Central United States [0.03%]

Triple oxygen isotope ratios Δ'17O offer new opportunities to improve reconstructions of past climate by quantifying evaporation, relative humidity, and diagenesis in geologic archives. However, the utility of Δ'17O in paleoclimat...
A Pliocene Precipitation Isotope Proxy-Model Comparison Assessing the Hydrological Fingerprints of Sea Surface Temperature Gradients [0.03%]
基于降水同位素的晚中新世气候模拟检验海表温度梯度对水文的影响
Scott Knapp,Natalie J Burls,Sylvia Dee et al.
Scott Knapp et al.
The Pliocene offers insights into future climate, with near-modern atmospheric pCO2 and global mean surface temperature estimated to be 3-4°C above pre-industrial. However, the hydrological response differs between future global warming an...
Improved Model-Data Agreement With Strongly Eddying Ocean Simulations in the Middle-Late Eocene [0.03%]
中始新世至晚始新世强烈涡旋海洋模拟模型与观测的一致性增强

Peter D Nooteboom et al.
Model simulations of past climates are increasingly found to compare well with proxy data at a global scale, but regional discrepancies remain. A persistent issue in modeling past greenhouse climates has been the temperature difference betw...
Biotic and Paleoceanographic Changes Across the Late Cretaceous Oceanic Anoxic Event 2 in the Southern High Latitudes (IODP Sites U1513 and U1516, SE Indian Ocean) [0.03%]
南高纬度地区晚白垩世大洋缺氧事件2的生物和古海洋学变化(东南印度洋IODP钻探站U1513和U1516)

Maria Rose Petrizzo et al.
Oceanic Anoxic Event 2, spanning the Cenomanian/Turonian boundary (93.9 Ma), was an episode of major perturbations in the global carbon cycle. To investigate the response of biota and the paleoceanographic conditions across this event, we p...
Episodes of Early Pleistocene West Antarctic Ice Sheet Retreat Recorded by Iceberg Alley Sediments [0.03%]
早更新世气候变暖期间 Antarçtica冰盖后退的冰筏沉积记录:来自冰川巷的证据

Ice loss in the Southern Hemisphere has been greatest over the past 30 years in West Antarctica. The high sensitivity of this region to climate change has motivated geologists to examine marine sedimentary records for evidence of past episo...
African Hydroclimate During the Early Eocene From the DeepMIP Simulations [0.03%]
深MIP模拟下的早期古新世非洲水气候研究

Charles J R Williams et al.
The early Eocene (∼56-48 Myr ago) is characterized by high CO2 estimates (1,200-2,500 ppmv) and elevated global temperatures (∼10°C-16°C higher than modern). However, the response of the hydrological cycle during the early Eocene is poo...
