Thwaites Glacier aka “Doomsday Glacier”, due to the fact being the world’s largest and most vulnerable, is a behemoth glacier sitting on the deep sea-floor in West Antartica that had been responsible for putting amount of voluminous burden and leaking water into the ocean. Generally, this glacier would be the major rapid supplier in making the entire world submerge into high sea-level cataclysm in the next few decades.
Where will it lead is thus the question.
Although frightening, Scientists seem to have thought knowing your fears is better than struggling in the unknown. And so, they have put up a video and photos for the first time. Using Icefin, a submersible robot, one of the scientist put the little guy into action to capture and record all what’s there is to see under.
The video shows “the warm ocean water working its way under Thwaites Glacier. The icy ceiling in the video is the bottom of the glacier’s ice shelf, the part of the glacier that floats in the water rather than sits on the seafloor. It’s more than 1,900 feet thick, and almost everything attached to the bottom of it was, only a few hours earlier, pressed into the Antarctic bedrock,” The Atlantic explained at length in its publication.
“The glacier is moving [several] meters a day, so that material we’re seeing at the grounding zone is brand new and is just exposed to the ocean,” divulged Britney Schmidt, a glaciologist at the Georgia Institute of Technology. “We can definitely see it melting. There are a few places where you can see streams of particles coming off the glaciers, textures and particles that tell us it’s melting pretty quickly and irregularly.”
It took four and a half weeks on the ice, in which Schmidt and her colleagues have spent their days on from late December to January. Setting up the robot and drilling through the ice is still out of the calculation on just how long they’ve been on the ice, in which Schmidt summed up, “We were pretty roasted.”
British glaciologist John Mercer had been studying this biggest mystery since 1978, in which he wrote in warning about the titanic glacier that the “rapid deglaciation of West Antarctica” would be the “first disastrous consequence of rising CO2 levels.”
In their finding, most glaciologists have termed the area “grounding line” where the glacier meets the seafloor. Others thought differently, in which they speculated that the area is “more like the estuary of a river, with tides bringing in ocean water and carrying out meltwater”, Robel said. In general, it showed something more like a “grounding zone”, a small pit-like scar area where the glacier is coming together and floats, before getting stuck on other boulders.
