This is pack-ice in the summer months
around the Antarctic peninsula.
This is to the east side of the Antractic Peninsula which is
much more prone to summer sea-ice from the Weddell Sea than
the usually ice-free west side of the Peninsula. The ice
looks fairly continuous, but has quite a lot of open water
between the pieces and so can be relatively easily pushed
aside by an ice-strengthened ship, in this case HMS
Endurance. Larger pieces such as this one that are hit by
the bow of the ship crack up into smaller pieces.
Proper Ice breakers have rounded hulls and rounded
bows rather than being sharp and pointed. When breaking through
very thick ice, the front of the ship rides up over the ice and
the weight of the ship breaks through.
Passage is slow though, and heavy on fuel. Most
of all, it takes an experienced and well informed ice-pilot to be
confident in entering such ice so as not to be locked into the pack
should the wind direction change and consolidate the ice.
