10. Oxygen escape
from the Earth during geomagnetic reversals: Implications to mass extinction
Yong Wei , Zuyin Pu , Qiugang Zong , Weixing
Wan , Zhipeng Ren , Markus Fraenz , Eduard Dubinin , Feng Tian , Quanqi Shi ,
Suiyan Fu , Minghua Hong
Geomagnetic
field reversal substantially weakens the protection for the atmosphere.
Solar
wind energizes more oxygen ions to escape when geomagnetic field is weakened.
Oxygen
escape may explain the drop of atmospheric level during mass extinction.
The
causal relation between reversal and mass extinction should be “many-to-one”.
The
simulated oxygen escape rate based on knowledge of Mars support our hypothesis.
11. Distinct roles
of the Southern Ocean and North Atlantic in the deglacial atmospheric
radiocarbon decline
Mathis
P. Hain , Daniel M. Sigman , Gerald H. Haug
Complete simulation of deglacial atmospheric ΔC14 decline.
New estimate of 14C production history consistent with
preindustrial 14C activity.
North Atlantic circulation changes and Southern Ocean CO2 release both required.
NADW onsets account for rapid ΔCatm14 declines during late
HS1 and YD.
“Early”ΔCatm14 declines implicate westerly winds as drivers
of NADW onset.

the Paleoproterozoic glaciations with 3-D climate modeling
Yoram
Teitler , Guillaume Le Hir , Frédéric Fluteau , Pascal Philippot , Yannick
Donnadieu
Maintenance of ice-free surface on Earth at 2.4 Ga requires
moderate pCO2.
Increase in weathering efficiency favored the onset of the Huronian
glaciations.
Onset of Paleoproterozoic snowball Earth requires pCO2 buffering and pCH4 collapse.

We present a new numerical technique for inferring temperature
from noble gases in ice cores.
We produce a temperature history independent from water isotopes.

is 11.8±1.8°C.

US-ESR age and age uncertainty for tooth enamel Qingfeng Shao, Jean-Jacques

Qingfeng Shao , Jean-Jacques
Bahain , Jean-Michel Dolo , Christophe Falguères
USESR program was developed for calculating US-ESR age for tooth
enamel.
This program uses Monte Carlo simulations for age and age
uncertainty calculations.
USESR was applied to a large number of virtual samples designed
with measured data.
Experimental results show that USESR can provide reliable age
results.
