Snow Dragons successful escape from an iceberg crash in Antarctica (Source: CCTV - News)

Today, an exclusive video sent back by CCTV reporters from Antarctica attracted attention. The Snow Dragon, which is on the 35th Chinese Antarctic expedition, crashed into an iceberg in the dense ice area of the Amundsen Sea, Antarctica. Many netizens are worried about the safety of the Xuelong. What is the specific situation? Lets look at it together.

At 10:47 a.m. Beijing time on the 19th, the snow dragon hit an iceberg and the news of the iceberg touched peoples hearts. CCTV reporters sent back exclusive videos. In the picture, ice and snow were piled on the deck of the ships fore. The preliminary estimate was 400 cubic meters, the total weight was about 250 tons, and the mast of the ship had broken.

CCTV reporter Wang Shantao: We didnt actually see the picture of the snow dragon boat crash, because I was still sleeping at that time. I woke up from the sound of a boom, but I was terrified to think about it, because I was still shooting under the mast just hours ago. At that time, the visibility outside was very low, the fog was very heavy, and the boat quickly retreated after touching the iceberg. They (crew) said that the iceberg could not be seen in 10 seconds, but some people who saw the iceberg said that the iceberg was really high. Immediately after the incident, a personnel count was made on the team, and it soon came out. All the personnel were safe.

Effective and timely response to the normal main system of Xuelong

Before hitting the iceberg, the Xuelong had slowed down ahead of schedule, at a speed of less than 6 kilometers per hour. After the collision, the crew backed up in time, which also reduced the damage of the iceberg to the ship. Except for the broken mast, some bulwarks were damaged, and the power and communication systems of the Xuelong were in good order.

Expert: Shipborne radar in dense ice areas has limited effectiveness

Netizens have said: Just be safe. However, some netizens also raised questions: with radar, why cant icebergs be detected? Experts said that in the dense ice area at that time, the role of Ship-borne Radar was limited.

Academician Chen Dake, the chief ship-based scientist of Chinas 35th Antarctic Expedition Team: (because) Now this radar cant distinguish icebergs from large areas of ice floe. Radar can only adjust its gain. If it has a big gain, it looks like its all, and its insensitive to adjust, so it cant be distinguished at all. We need to develop new technology.

Expert: Foggy and unexpected climate change is multifaceted

Academician Chen also said that at that time, the fog was very heavy and the poor weather conditions could only be observed by the crew, but it could also be observed very close to the iceberg, and the fog came very suddenly.

Academician Chen Dake, chief ship-based scientist of Chinas 35th Antarctic Expedition Team: If its always foggy, maybe well be very careful at the beginning, and suddenly its getting bigger. The weather in this area is changeable, and its also a big factor.

Oceans of the Incident: People know less about it than the Moon.

In fact, the Amundsen Sea is located in the Pacific sector of the Antarctic Antarctic Ocean, where the Westerlies and the atmosphere of the Southern Ocean swirl one after another. Even waves 6 to 8 meters high are not uncommon. There are many ice floes and icebergs near the shore, and navigation conditions are very complex. It is for this reason that man knows less about the sea than about the moon. Last year, Chinas 34th Antarctic Science and Technology Research Team completed its first comprehensive survey of the Amundsen Sea in the Antarctic by taking the Snow Dragon boat in this sea area.

Xuelong adjustment plan will be further tested

At present, snow has been cleared up in the bow of the Xuelong. For the sake of safety, the Xuelong has adjusted its original scientific research plan.

CCTV reporter Wang Shantao: Originally we were going west, but now we are going east to go to the Great Wall Station. After arriving at the Great Wall Station, there will be domestic ship experts to do further physical examination of the Xuelong boat.
