"When the ice gets tough, the best weapons we have are the ship's heeling tanks," Stromsnas said. There are a pair of tanks on the port and starboard sides that each can be filled with up to 400 metric tons of water. "You have the full weight of the ship and the added weight of the water on the ice," he said. The water can be shifted from one side of the ship to the other through the large-diameter pipe above-in about 15 seconds. That causes Oden to list back and forth, from one side to the other, which helps break ice. The ship can be set to do this automatically, something the crew calls the "duck walk." "You can hear the hum of the water going through the heeling system," Stromsnas said, "so you can keep track of what's happening outside and know there is tough ice, even when you're in bed."
