Antarctic lake ‘suddenly vanished’ in 2019, scientists say

A huge ice-covered lake in East Antarctica has been left to wither away in less than a week, possibly due to climate change, according to a new study.

Most ice shelves in the world embrace the shoreline of Antarctica.

While experts are not sure how the lake vanished so soon, the most plausible scenario is that the lake ground submerged under this immense load.

It was too early to conclude that draining this meltwater lake is connected to global warming around Antarctica, the team said.

This is extraordinary not only due to the lake’s size, but also because this water drains through the ice.

Hypothesis is that the hydrofraction process is involved in the breakdown of smaller ice shelves on the Antarctic Peninsula, where, in the summer, meltwater forms on the surface of ice shelf.

The researchers want to apply the acquired knowledge, along with the modern satellites which captured the cruel death of the lake (aptly named ICESat-2), to gather more information on the retreat of the Antarctic ice shelf.

Subglacial lake

A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, (wikipedia)
