Some people have posted the pictures online, taken by scientist Tony Travouillon at Dumont D'Urville, with a description claiming they are a tsunami wave which was frozen.
These freezing blue towers were created when ice was compressed and the trapped air bubbles were squeezed out. During the summer the surface ice melts and new ice layers compress on top.
