In a shocking natural incident, a massive hole has formed in the ice of Antarctica leaving scientists baffled to why it’s there. Atmospheric physicist Kent Moore, a professor at the University of Toronto said that the hole is quite remarkable and it looks like you just punched a hole in the ice.
“This is hundreds of kilometers from the ice edge. If we didn’t have a satellite, we wouldn’t know it was there.”
In the year 1970, A polynia was observed in the same location, in Antarctica’s Weddell Sea but at that time observation tools weren’t nearly as good, so that hole remained largely unstudied.
Moore, who’s been working with the Southern Ocean Carbon and Climate Observations and Modelling (SOCCOM) group, based at Princeton University said:
“This is now the second year in a row it’s opened after 40 years of not being there. We’re still trying to figure out what’s going on. Once the sea ice melts back, you have this huge temperature contrast between the ocean and the atmosphere.”
Moore further added: “It can start driving convection.” Denser, colder water sinks to the bottom of the ocean, while warmer water comes to the surface, “which can keep the polynia open once it starts.”
