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 是一位地质学家，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.

回到家后，他把从碎石场、岩心和滑坡可能经过路径上采集样本送去进行年代测。

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，科学家们能够弄清草木茂极如何逐渐被冰雪覆盖。

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，这块岩心具有极好沉积物记录——这是极端季节变化充分证据。

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每分每秒细节。

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

“毅力”号火星车在接下来一个月里仔细地手指大小岩心放置在地面上。

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.

对沉积物岩心分析显示，那时夏天气温能到约 15-16 摄氏度——比极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模式，并告诉地质学家下一步钻探最佳地点。

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

美国国家航空航天局工程师后来报告说，火星车钻入岩石一不够坚固，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.

最新岩心样本——以及从现在开始收集所有其他样本——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.

。他岩心挂在办公室墙上，后来这名男子在移民美国时，这根3.5英尺长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 50 米岩心显示， 石灰石平均浓度约为 10%，但对于一段 4 米岩心， 浓度升至近 50%，这是巨大且完全异常。

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。世界各地科学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线索。
