人類史上最大的謎團終於解開了！ (The Biggest Mystery In Human History Was Just Solved)
- It happened during an abrupt warming event that lowered lake levels at the time in a way that when humans walked over the wet and dry ground, they left footprints that became preserved in multiple sediment layers that were dug up by scientists in the last few years.
結果發現，人類在大約 22,000 年前也在這裡留下了獨特的腳印。
- It happened during an abrupt warming event that lowered lake levels at the time in a way that when humans walked over the wet and dry ground, they left footprints that became preserved in multiple sediment layers that were dug up by scientists in the last few years.
這發生在一次突然的暖化事件中，當時湖泊水位下降，人類走過潮濕和乾燥的地面時，留下了足跡，這些足跡被保存在科學家們在過去幾年挖掘出來的多層沉積物中。

- Permafrost is rock, sediment or ice that remains at or below zero degrees Celsius for two or more consecutive years.
永久凍土是指連續兩年或兩年以上保持在零攝氏度或零攝氏度以下的岩石、沉積物或冰。
- Permafrost is rock, sediment, or ice that remains at or below 0°C for two or more consecutive years.
北極的永久凍土往往有幾千年的歷史，而在南極地區，我們發現的永久凍土有幾百萬年的歷史。
人類世的爭議，一次搞懂！ (The debate over the Anthropocene, explained)
- That means the sides slope dramatically downwards, and the water at the bottom doesn't mix with the water at the top, making the sediment underneath extraordinarily well-preserved.
這意味著兩側的坡度極大地向下傾斜，底部的水不會與頂部的水混合，是以底部的沉積物保存得特別完好。
- It's this unique quality that attracted scientists in 2023 to dig up a sediment sample from the lake.
正是這種獨特的品質吸引了科學家於 2023 年從湖中挖掘出沉積物樣本。

- The grinding of rocks, which puts sediment in the water, I think is a color that is distinctly unique and looks great in photos against the red canoe.
我認為，岩石的打磨會將泥沙帶入水中，這種顏色非常獨特，在照片中與紅色獨木舟相映成趣。
- It comes from the glacial runoff, the grinding of rocks, which puts sediment in the water and gives it a color that is distinctly unique and looks great in photos against the red canoe.
