Brinicles

What’s a huge ice spike doing under water? Okay, time to read it attentively if you want to understand the concept of Brinicles. It occurs in the north and south poles when the salty seawater gets collected under the frozen sheet of water. What makes this water sink is the fact that it’s not only cold and salty but also denser than the fresh water and the sea water underneath it. This mixed brine then starts to sink passing by the seawater. On its way to the bottom of the ocean, the freshwater too freezes by the cold salty water resulting in a large icicle under the surface.
