- 1Scientists explain massive open-water hole in Antarctic ice●A Massive Hole Opened Up in Antarctica. Scientists May Have Finally Figured Out Why The open-water hole stretched across
A vast polynya, an area of open water in Antarctic sea ice, stretched across roughly 34,400 square miles, about the size of Portugal. Scientists now believe they have identified the physical processes behind its formation, potentially involving ocean currents and heat from deeper waters. The finding is drawing attention for what it reveals about polar ocean dynamics.

A large, unprecedented hole, known as a polynya, has opened in the sea ice around Antarctica during the depths of winter. Researchers report the phenomenon is rare and unexpected in winter conditions, drawing attention to what it may reveal about ocean circulation and the changing polar climate.

Scientists report that global warming is causing an ever-increasing number of polynyas to form in Antarctica. A polynya is a large hole in the sea ice, an area of open seawater surrounded by ice that in winter can reach a surface area roughly the size of Portugal. The trend is raising concern about accelerating ice loss in the region.
