The world's largest ice berg is on the move!
https://www.smithsonianmag.com/smart-news/the-worlds-largest-iceberg-is-drifting-three-miles-into-the-ocean-each-day-180983326/
(partial excerpt)
[IMG]Called A23a, the iceberg measures around 1,500 square miles—more than 20 times the size of Washington, D.C.—and it’s roughly 1,300 feet thick, making it two and one-third times the height of the Washington Monument. It weighs nearly one trillion metric tons. Chad Greene, a glaciologist at NASA’s Jet Propulsion Laboratory, tells New Scientist’s James Dinneen that large icebergs like A23a break off from Antarctica around once per decade. Sometimes, they get stuck in the Antarctic’s cold waters, which staves off their melting, but only for a while. “Icebergs this big can hang around for decades in one place, then one day decide to go for a jolly,” Greene says to the publication. “That’s when things get interesting.” A23a did just that—it broke off from Antarctica in August 1986, then it became grounded on the floor of the Weddell Sea, which is part of the Southern Ocean between Antarctica and South America. Andrew Fleming, the remote sensing manager at the British Antarctic Survey, first noticed the iceberg was moving again in 2020, he tells BBC News. Satellite imagery from the British Antarctic Survey showed currents and winds pushed the iceberg thousands of kilometers through the Weddell Sea in 2022 and 2023.[/IMG]
