Most of us woke up to presents (and/or a welcome day off from work) on Christmas morning. The MV Akademik Shokalskiy ship, on the other hand, found itself trapped in ice up to 10 feet thick on all sides.
The research vessel sent out a distress signal, hoping help would arrive as quickly as possible, considering the 74 crew members were currently sitting in the Antarctic sea.
Luckily, there's a ship for that.
Icebreakers have helped carve paths through frosty seas since the 1800s; of course, the designs of these behemoths have much improved upon the glorified whalers that once sliced through the ice. Three such ships were expected to reach the stranded research vessel by Friday night; the crew is on an expedition to measure the effects of climate change.
Below, a look back at the boats that helped humans explore new — very cold — lands:
