郭正府等-NC: 印度-亚洲大陆碰撞导致新生代大气CO2浓度变化(图)
郭正府 新生代 大气 CO2浓度
2021/6/30
新生代以来全球气候变冷是地球科学领域广泛关注的焦点问题之一,被认为与大气CO2浓度降低有密切的联系。青藏高原隆升及其相关的深部-表层相互作用在新生代气候转型过程中起着重要的作用,然而关于印度与亚洲大陆汇聚、碰撞、俯冲过程与新生代大气CO2浓度变化的具体作用机制仍存在很大的争议。一种观点认为,青藏高原隆升导致地表硅酸盐风化作用增强,加速消耗大气圈中的CO2,从而造成大气圈CO2浓度降低;另一种观点认...
Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow
2018/3/23
CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
A coupling alternative to reactive transport simulations for long-term prediction of chemical reactions in heterogeneous CO2 storage systems
transport simulations chemical reactions
2015/3/5
Fully coupled, multi-phase reactive transport simulations of CO2 storage systems can be approximated by
a simplified one-way coupling of hydrodynamics and reactive chemistry.
Tunable diode laser measurements of hydrothermal/volcanic CO2 and implications for the global CO2 budget
CO2 low temperature volcanic hydrothermal volcanoes laser and other quantitative volcanoes volcanic hydrothermal
2015/1/6
Quantifying the CO2 flux sustained by low-temperature fumarolic fields in hydrothermal/volcanic environments has remained a challenge, to date. Here, we explored the potential of a commercial infrared...
First observational evidence for the CO2-driven origin of Stromboli's major explosions
CO2-driven origin Stromboli's major explosions
2014/12/31
We report on the first detection of CO2 flux precursors of the till now unforecastable "major" explosions that intermittently occur at Stromboli volcano (Italy). An automated survey of the crater plum...
CO2的地质埋存处理是减缓温室效应的现实选择之一。要保证埋存的有效性、安全性和持久性,需要对钻井(主要包括注入井和废弃井)、CO2地下分布运移状况以及因CO2渗漏所造成的环境影响等方面实施严格的监测管理。通过对以上各方面文献的查阅和综合分析,系统阐述了世界范围内目前CO2地质埋存过程中所采用的各项主要监测技术。

2009/6/9
Analytical, purely model-based probability distributions are derived for the instantaneous global mean warming resulting from a gradual doubling of CO2 (TCR = transient climate response) and for the e...
降水过程对断层CO2气体异常排放响应的个例分析
地震 断层气CO2 降水
2009/5/31
为了从观测事实的角度揭示岩石圈的热异常对大气圈的影响,本文利用怀来后郝窑测点的断层气CO2排放观测数据和中国752站降水的逐日观测资料,分析了断层气CO2异常排放与降水事件的时空演变联系.个例分析结果表明,断层气CO2的异常排放会导致局地降水的增多.以1991年为例,伴随着断层气CO2排放的异常增加,在大范围降水负异常的背景下,CO2排放点周边区域出现显著的降水正异常(降水距平百分率大于零)区.同...
