(South China Morning Post) - The Xue Long, or Snow Dragon, icebreaking research ship was on its 35th Antarctic expedition when the collision took place. It had been travelling at 3 knots, or about 5.5km/h, at the time. The force of the collision broke the ship’s mast and left about 250 tonnes of snow and ice piled up on its prow and front deck.
