Scientists will now drill into one of the most difficult to access and least-understood areas of the glacier in order to directly observe the processes that cause warm ocean water to melt the ice above. The researchers will be looking into “underwater tsunamis”, which can span from 10 to hundreds of metres, researchers told Sky News Australia. “These big underwater waves, with amplitudes of 10s to possibly hundreds of meters, what that can do is mix deep water with water closer to the surface. We have to understand that in order to make those better predictions about sea ice melt,” BAS oceanographer Dr Alex Brearley told the broadcaster.
