在华盛顿的AAAS会议,来自卡内基科学学院的Robert Hazen发表演讲。该演讲旨在展示上述对碳循环的的看法仅仅触及表面。
Dr Hazen is one of the moving spirits behind a projectcalled the Deep Carbon Observatory, which will be paid for by the Alfred P.Sloan Foundation.
Hazen博士是被称作深碳观测站项目的幕后策划者,该项目由Alfred P. Sloan基金出资。
Over the course of the next decade it will attempt to understand all the carbon in theEarth, not just the stuff that cycles through the atmosphere, the oceans and living things.
接下来的十年中,该项目将试着去了解地球上所有的碳,而不仅仅是通过大气、海洋和生物循环的东西。
As Dr Hazen pointed out, carbon is the fourth-most-abundant element in the universe,after hydrogen, helium and oxygen.
正如Hazen博士指出的那样,在氢、氦、氧之后,碳是宇宙中第四充足的元素。
In the Earth, though less common than that, it is reckoned to make up between 0.07% and3.2% of the planet.
在地球上,尽管没有宇宙那么常见,据估计有0.07%到3.2%是由碳构成的。
But the uncertainty of this range is itself a comment on how little carbon s role in theEarth s overall physics and chemistry is understood. Also uncertain is how muchinterchange there is between the carbon in the Earth s mantle and core, and the morefamiliar stuff in the crust, atmosphere and oceans.
