Africa-Press – Lesotho. Despite losing its water in the span of mere days, the lake has already replenished itself in a relatively short period of time. A large lake located amid the frozen expanse of Antarctica ended up vanishing in a relatively short span, only to regain its water later, Live Science reports.
According to the media outlet, this development apparently occurred during the 2019 winter when the ice-covered lake containing an estimated 600-750 million cubic metres of water simply drained into the ocean. Based on satellite observation, researchers concluded that the drainage took about three days, after the ice shelf beneath the lake gave way.
The research team also warned that “Antarctic surface melting has been projected to double by 2050, raising concerns about the stability of other ice shelves,” and that “processes such as hydrofracture and flexure remain understudied.
As the media outlet points out, the lake already refilled with water during the summer of 2020, with the process taking only a few days, though it remains to be seen whether that water is already seeping out through the old fracture, or if it will create a new one.
