The largest iceberg on Earth has been stopped in its tracks. Known as A23A, this so-called 'mega-berg' had been floating around in the South Atlantic. But scientists who have been tracking its path say it seems to have run aground near South Georgia Island,

“We are seeing lots of rays and squid around us at night, hunting the flying fish. In the middle of the subtropical ocean seeing such large predators is unusual, suggesting that the nutrient-induced changes to the plankton community are also useful to the rest of the marine food chain over the ridge.”

The iceberg broke off from Antarctica in 1986, and has been drifting in the southern Atlantic for years.
