The seas around Antarctica could be some of the roughest in the world. Huge waves crashed against small boats, sometimes lifting them right up before dropping them back down again. The sound of crashing waves and rushing water could be very loud, especially when travelling in a small open boat far from land.
Did you know? Waves in the Southern Ocean can be some of the biggest anywhere on Earth, because there's no land in the way to slow them down as they travel all the way around the world.
Try It Yourself Can you make the sound of a wave? Try saying "whoooosh" softly, then a little louder, like a wave rising up and then crashing back down.

During one especially dangerous voyage in a small boat called the James Caird, huge waves crashed over the sides and lifted the boat high into the air.
