The night before he turned 90 years old, he decided to return it to England.

他在90岁生日前夜决定将岩心归还英国。

In Mexico, researchers have drilled rock cores from the Chicxulub crater.

在墨西哥，研究人员从希克苏鲁伯陨石坑钻出了岩心。

The cores chronicle in minute-by-minute detail the asteroid impact that wiped out the dinosaurs.

岩心记录了小行星撞击地球导致恐龙灭绝的每分每秒的细节。

They compared that core with another from Arizona, embedded with zircons.

他们将这岩心与亚利桑那州一嵌有锆石的岩心进行了对比。

The Perseverance rover will spend the next month carefully placing the finger-sized cores on the ground.

“毅”号火星车将在接下来的一个里仔细地将手指大小的岩心放置在地面上。

They took a rock core from the east coast, which has excellent sediment records-good evidence of extreme seasonal variations.

他们在东海岸采集了一岩心，这岩心具有极好的沉积物记录——这是极端季节变化的充分证据。

But what happened to that core? An employee from the company that helped repair the sarsen held onto it.

那被取出的岩心去哪里了？当时有一家公司为修复萨尔森石提供帮助，正是这家公司的一名雇员保留了一岩心。

The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat.

科学家们还相信木卫二的岩心是不断散发着热量的火山热源。

It confirmed that the cores had alternating layers of iron-rich and iron-poor sediment.

它证实了岩心具有 交替的富铁和贫铁沉积层。

In older times, people used the first borehole as fridge to store consequent cores in there.

在过去，人们将第一个钻孔用作冰箱，以在存随后的岩心。

NASA engineers later reported that the rock the rover drilled into must not have been strong enough to produce a core sample.

美国国家航空航天局的工程师后来报告说，火星车钻入的岩石一定不够坚固，不足以产生岩心样本。

Software will then search these for patterns that will assist the interpretation of new cores, and tell geologists the best places to drill next.

然后，软件从检索，寻找有助于解释新岩心的模式，并告诉地质学家下一步钻探的最佳地点。

Back home, he sent samples from the rubble field, the rock core and others from the path the landslide might have taken for dating.

回到家后，他把从碎石场、岩心和滑坡可能经过的路径上采集的样本送去进行代测定。

This  was swiftly followed by a third and fourth core, both taken from the rock named  " Rochette" in early September.

随后很快又出现了第三个和第四个岩心，均于九初从名为“罗切特” 的岩石取出。

But the expedition was able to recover sediment cores stretching all the way down to the underlying rock-a thickness of 100 metres in some cases.

但是这次探险能够恢复一直延伸到地下岩石的沉积物岩心，在某些情况下厚度达了100米。

Using a sediment core as a detailed history of climate change, scientists can see how the forested Arctic gradually became covered in ice and snow.

将沉积物岩心作为气候变化详尽说明，科学家们能够弄清草木茂盛的北极如何逐渐被冰雪覆盖的。

He put it on the wall of his office, and the man eventually moved to America bringing the three and a half foot core with him.

。他将岩心挂在办公室的墙上，后来这名男子在移民美国时，将这根3.5英尺长的岩心一并带到了美国。

Analyses of sediment cores have revealed that back then summers reached about 15 to 16 degrees Celsius, a good 8 degrees warmer than modern Arctic summers.

对沉积物岩心的分析显示，那时夏天气温能到约 15-16 摄氏度——比北极现在夏天气温至少高了 8 度。

" So what YOU could do is flap around and look for boats so we can get back on the right cores" .

" 所以你可以做的就是四处寻找船只，这样我们就可以回到正确的岩心上。"

" It's official: I've now captured, sealed, and stored the first core sample ever drilled on another planet, in a quest to return samples to Earth" .

" 这是官方消息：我现在已经捕获、密封并存了第一个在另一颗行星上钻取的岩心样本，目标是将样本带回地球。"
