Hidden Worlds Beneath Greenland’s Ice

Greenland landscapes beneath Greenland’s massive Jakobshavn Glacier.

Hidden Worlds Beneath Greenland’s Ice
A red line shows the main channel, and the elevation ranges from 300 to 1,300 meters above sea level, with higher elevations shown in white and brown and lower elevations in yellow and green.


The study, published in Geophysical Research Letters, reveals an extensive network of ancient rivers. These rivers predate Greenland's ice sheet by more than three million years and once drained a region that's about the size of the Ohio River basin.

Some of those river channels were more than 7 miles (11 kilometers) wide and 4,500 feet (1.3 kilometers) deep. While that’s not as big as the Grand Canyon - which reaches 18 miles (29 kilometers) wide and more than 6,000 feet (1.8 kilometers) deep - it is bigger than a megacanyon discovered beneath Greenland’s ice.

How Long Does Plastic Take to Decompose?

  Plastic: the unwelcome house guest at nearly every corner of our lives — from shopping bags to footwear, coffee cups to car parts. And yet, discarded, plastic doesn't just evaporate into thin air. No, it lingers. For decades. Even centuries. According to statistics presented by Visual Capitalist , plastic daily consumer goods can break down between 20 and 600 years, depending on the composition used, how they were created, and natural elements like water and sunlight they are exposed to. Let's go deeper into why plastic takes so long to break down — and what horrid messes it leaves behind in the process. Why Plastic Isn't "Natural" — and Why That's a Problem Plastic does not naturally exist. It's a product made from petroleum and natural gas. Its long, tough carbon bonds differ from anything naturally found in ecosystems, making it extremely resistant to microbial breakdown. When we toss a plastic bottle or bag away, it's not a matter of if it will s...
