An Antarctic ice hole the size of Switzerland continues to crack. Now scientists finally know why.

Scientists have finally discovered why a hole the size of Switzerland repeatedly appears in Antarctica’s sea ice.

The hole, called the Maud Rise polynya, was first discovered by researchers in 1974 and 1976 in Antarctica’s Weddell Sea, and since then it has reappeared fleetingly and sporadically — opening up to different sizes but in the same place, and sometimes not appearing at all for years. This has left scientists confused about the exact conditions needed for the hole to form.
