It's been collecting hourly data on measurements like the mountain's air temperature, total precipitation, humidity, and wind speed since the early '90s. On warm days, as sunlight heats the glaciers, the air just above the glacier's surface warms and rises. This creates a vacuum causing the cold air around the snowy peaks to rush down due to gravity. Then at night, the ice releases some of that stored heat energy, preventing the air temperature from dropping too low. The terrain has also gotten more technical as melting glaciers open up huge crevasses.

And it’s not just the winds making the waters rough – the Drake is basically one big surge of water. We’re not gambling.”Even with that extra safety margin, though, he admits that crossing the Drake can be a hairy experience. A dangerous thrillAurora Expeditions' Greg Mortimer ship has a patented bow to make a Drake crossing more stable. “The only thing that works for me is going to the ship’s medic for a scopolamine patch,” he says. “If you were going to the moon, you’d expect the journey to be uncomfortable but it’d be worth it,” she says.
