Digging out core samples are a common experiment these days in Antarctic ice. So what exactly is a core sample?
It's a super long shaft of ice—often many metres in length— that is removed from the caps in Antarctica. This frozen tube is a window into the past, as the ice at its base is usually around 800,000 years old. By examining it, researchers can learn about the composition of water and the atmosphere when it was made. This is a great way to try and understand more about how the atmosphere today has changed and how that might be linked to global warming.
But after the core has been pulled out and the science is done, you're left with a slim 90-metre (295-foot) long borehole leading to nowhere. Does that sound "bore"ing to you? If so, you're not thinking hard enough!
Thankfully, the scientists on one of the missions figured out a good use for one of the holes in Antarctic ice. They dropped a chunk of ice down it!
Can you imagine what it sounds like? Even with our description, we think you'll be pretty surprised!
