Fridtijov Riis is a geologist who has long been searching in the drill core archive for the optimum sediment into which the first industrial carbon dioxide will be injected.

Fridtijov Riis 是一位地质，他长期以来一直在钻探岩心档案中寻找可以注入第一批工业二氧化碳的最佳沉积物。

" 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、密封并储存了第一个在另一颗行星上钻取的岩心样本，目标是样本带回地球。"

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，在某些情况下其厚度达了100米。

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年代测定。

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.

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

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块岩心，这块岩心有好的沉积物记录——这是端季节变化的充分证据。

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。

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

“毅力”号火星车在接下来的一个月里仔细地手指大小的岩心放置在地面上。

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——比北现在夏天气温至少高了 8 度。

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，软件从中检索，寻找有助于解释新岩心的模式，并告诉地质下一步钻探的最佳地点。

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。

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

他们这块岩心与亚利桑那州一块嵌有锆石的岩心进行了对比。

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？当时有一公司为修复萨尔森石提供帮助，正是这公司的一名雇员保留了一块岩心。

The latest core sample -- and all others collected from now on – will be stored on Mars until they can be picked up during future missions to the Red Planet and brought to Earth.

最新的岩心样本——以及从现在开始收集的所有其他样本——被储存在火星上，直到它们可以在未来前往这颗红色星球的任务中被取走并带回地球。

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.

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

A 50-metre core drilled out of the rock showed an average concentration of limestone of around 10%, but for one 4-metre stretch the concentration rose to nearly 50%, which is enormous and completely abnormal, he says.

他说，从岩石中钻出的 50 米岩心显示， 石灰石的平均浓度约为 10%，但对于一段 4 米的岩心， 浓度升至近 50%，这是巨大且完全异常的。

So, there was a lot of detective work involved. Scientific teams around the world have been studying coastal marshes, taking cores, looking for clues about where things grew, at what times.

因此，涉及很多侦探工作。世界各地的团队一直在研究沿海沼泽，采集岩心，寻找有关事物生长地点和时间的线索。
