Pressure Ridges

I went on a tour of the pressure ridges off of Scott Base. The pressure ridges are formed as the ice from the Ross Ice shelf slowly pushes into the sea ice. The formations are due to the immense pressure that results.


Looking out at the start of the trail from Scott Base. On some years there is open water from the coast by Scott Base to the Ice Shelf.












Looking back at Scott Base from the pressure ridges. Mount Erebus is on the right, Castle Rock is just to the left of Erebus, Observation Hill is just outside of this shot on the left. You can see the pressure ridges in the shot of Scott Base from the entry on Observation Hill.








Evidence of seal in the area. I have seen seals in the area when I ride by the pressure ridges every day for work.

















Evidence of a penguin, but the penguin was headed in the wrong direction. The penguins are all on the other side of the island right now, but they may venture over here when the sea ice starts opening up.
