Antarctic Winter Festival | Listening to the ice and snow Antarctic "Night Stoper" tells the story of wintering

Antarctica that is far away from the motherland

There is such a group of people

They are in the long night

Persist in my country's Antarctic Inspection Station

Carry out wintering work

In more than 200 days of leaving the motherland

They contribute wisdom and strength to the motherland's Antarctic scientific examination

Today is June 21, the summer solstice of the northern hemisphere

And in Antarctica,

They will usher in the Winter Festival,

From then on, the long night ended,

Welcome to the sun!

Start sunrise

Sunrise

The sunrise is completed, yes, this is the state of the sunrise ... (the above pictures are from i natural all media)

June 21 is the summer solstice of the northern hemisphere, but the most important festival in Antarctica -Winter Winter. After this day, the polar night meeting of Antarctica gradually disappeared. The Winter Winter Festival is a holiday without borders and race. The Antarctic Investigation Station of various countries is agreed to be a holiday on this day. Therefore, this day also became a proprietary festival of "Antarctic".

my country's Antarctic Investigation is divided into two types: Du Xia Investigation and Winter Winter Investigation. Among them, after the wintering inspection team members took the inspection ship to the Antarctic with the Duxia Inspection team, they generally adhered to 14 to 17 months at the Antarctic Survey Station.

During wintering, the most difficult thing is the long night. Extreme night, also known as Yongye, refers to the phenomenon of the sun in the polar areas of the earth within a day, that is, 24 hours a long night. In contrast, the extreme day. Taking the China Antarctic Zhongshan Station in the Lasman hills in the Antarctic continent as an example, there are more than 50 days of extreme nights and more than two months of polar days each year. In the long night, my country's Antarctic wintering team members still insist on observing data, geomagnetic, high -altitude physics and other data.

The arrival of the extreme night brings greater challenges to the lives and work of Antarctic inspections. Moving, insomnia, anxiety breeding ... The natural environment of extremely cold, long -term closed and isolated social environment, double challenges, how can my country's Antarctic wintering inspection teams defeat difficulties to complete the task? What dangers did they experience during wintering? What kind of scientific passwords are hidden behind the dazzling aurora? Recently, the reporter interviewed a number of players who participated in the wintering inspection tasks of the Antarctic Zhongshan Station, and listened to their storytelling story in the "Night" in the ice and snow Antarctic.

Zhang Mengyu: The escape experience in the wind and snow

From the end of 2016 to the beginning of 2018, Zhang Mengyu participated in the 33rd Antarctic scientific survey in China. As an assistant and administrator of Zhongshan Station, he began a 16 -month -old Antarctic life.

"During the extreme night, there are often big storms and strong snowfall near Zhongshan Station." Zhang Mengyu told reporters that the storm sometimes blows off the skin of several old buildings on the station. Buried at low terrain.

During the wintering, Zhang Mengyu had a job to be responsible for writing Zhongshan Station Weekly- "Zhongshan Life". One night, he was forgetting time, and he forgot time, and he was busy at 23 o'clock in the comprehensive building. When he finished his work, he found that the teammates in the comprehensive building had already returned to the dormitory to sleep. At this time, Zhongshan Station has been snowing for several days in a row. Although the mechanic was arranged to drive the engineer to shovel the engineer in the "day", it often produced a lot of snow after a few hours.

When Zhang Mengyu put on a thick "penguin suit" out, the snow outside was nearly one meter thick. There are two dormitory buildings in Zhongshan Station, one is a new dormitory, which is connected to the corridor with the comprehensive building; the other is an old building. It needs to walk out of the comprehensive building and pass through a bridge to pass. Zhang Mengyu's dormitory happened to be in the old building.

Standing downstairs, Zhang Mengyu first tried the thickness of the snow. He felt that before he was so on, he walked towards the bridge. The cold wind was blowing with snow particles, and it hurts on his face. He stepped forward hard. The passage that had just walked behind him was quickly covered by the snow next to him, as if no one had passed.

When he walked to the middle of the bridge, Zhang Mengyu found that the snow hadn't passed the waist, and the wind was increasing, and the movement became more difficult. At this time, he already regretted it, so he reached out to the walkie -talkie in his pocket, and wanted to ask a few players to come over to respond, but he didn't want to touch it. "It's broken, the intercom is charging in the office!" Zhang Mengyu hit a spirit in his heart, began to worry, and looked back. When he came, the road was completely covered by snow.

At this time, the wind became bigger and bigger, and Zhang Mengyu, who was in dilemma, felt that the snow slowly rose like a tide. Cold, fear, regret ... all emotions rushed into my heart, and even began to be exhausted with the body. "If no one comes to rescue, he is likely to be buried by Blizzard." He began to regret and fear his intentions.

After a while, the desire for survival made Zhang Mengyu calm down. Looking around, he found that around the old dormitory building, due to the obstacle of obstacles and the influence of wind blowing, there was a passage around the building with only a small amount of snow. It is important that this channel is only four or five meters away from him.

"I can only jump down at the moment, and I go back from this channel." Zhang Mengyu turned his body to the channel direction, pressed the snow in front of him with both hands, leaned forward, and moved step by step with the weight of his body. Usually, just a few steps of kung fu, but at this time, it is like a thousand miles. Finally, he came to the passage and jumped in and realized himself.

Today, Zhang Mengyu talked about this experience. He told reporters that for a long time after the incident, his heart was a little scared, but this experience also brought him a fearless spiritual force, supporting him to fight hard in the future Antarctic inspection work.

Wang Junming: The "electric nanny" of the inspection station is in the Antarctic continent that is far away from the smoke. Electricity is an important guarantee for the work and life of Antarctica to work.

Wang Junming is the 37th China Antarctic Scientific Investigation Team Zhongshan Station overwintering. He serves as an important position of generator mechanic and power generation team leader of Zhongshan Station District. "The power generation of the power generation in Zhongshan Station provides power guarantee for the entire inspection station, which is the 'heart' of the inspection station." Wang Junming, who has performed many Antarctic wintering power generation tasks, said, "Power generation positions are a more important post in the entire station area. It is related to the daily research work and life of the team members, and it is also an important guarantee for communication, scientific research, fire protection equipment and station operations. We must ensure that the power generation equipment is running normally. Even late at night and early morning, we must not be indifferent. "

After Wang Junming arrived at the station, the primary work was to transport the diesel that came with the boat to the oil tank in the station area, and then made the monthly generator set and the fuel boiler, and the oil consumption statistics of the construction machinery vehicle in the station area. Changhe China Polar Research Center to ensure the amount of fuel this year.

Wang Junming said that every day, personnel on duty are strictly in accordance with the post requirements of the inspection team and take a serious inspection work. Every two hours, we must inspect the operation of all equipment such as diesel generator sets, boiler rooms, and water treatment rooms, and make records. If the device is found abnormal, report it in time, and cooperate with maintenance personnel such as water heating.

An experience of repairing during the winter impressed Wang Junming. One day in April 2021, when Wang Junming inspected the boiler room, he suddenly found that the fuel boiler did not work normally, and the heating of the station area was affected.

After the problem was found, Wang Junming immediately informed the webmaster and water heating worker, and the relevant personnel launched the repair in time. The time passed by every minute, and during the period, the maintenance personnel continued to communicate with domestic equipment manufacturers, but 10 hours passed, and the fuel boiler computer board was still unable to enable. Wang Junming was so anxious that after discussing with everyone, he decided to start with the circuit to change the starting mode of the fuel boiler, and use the mechanical mode to perform the heating of the work operation area. After some efforts, everyone finally successfully launched the fuel boiler to ensure the normal operation of the inspection station.

Wang Junming often compares himself to the "electric nanny" of Zhongshan Station. He said: "In the long extreme night, keeping electricity on the stations is the value of my work!"

Huang Wentao: The chaser in the extreme night

For researchers at the Institute of Space Physics and Astronomy, the 35th and 36th Antarctic Scientific Investigation Team players Huang Wentao, the 35th and 36th Antarctic Research Institute, his Antarctic wintering work is quite romantic.

North and South Pole is the entrance of the energy and particles of the solar wind and particles. It is the energy source of the energy and weather of catastrophic spaces such as magnetic storms, ionization storms, and particle violence caused by the earth space. The geomagnetic field is almost vertically in and out. At the same time, the various dynamic processes that occur in the outer space of the earth will be projected along the magnetic line to the North and North Pole. The phenomenon of aurora, magnetic field disturbance, plasma convection, radio absorption and flashing in the polar region, which contains rich space weather information. Essence Therefore, Aurora is called the "animation" of space weather, and the ionization layer of the polar region is called the "display" of the space weather.

"The physical observation of high -altitude atmosphere in polar areas is of great significance for establishing spatial weather models, improving radio long -distance communication, and determining satellite orbit." Huang Wentao introduced that at the middle layer of the atmosphere around 90 kilometers above the Antarctica and the middle layer of the space boundary The top area is one of the correlation points of the atmosphere and space weather activity of the polar region. In February 2019, he and the inspectors completed the installation and commissioning of the sodium fluorescent Doppler lidar detection system at Zhongshan Station, which realized the high level of atmospheric temperature and the active optical remote sensing detection of this high level, marking that my country is extremely in the extreme The area of ​​district atmosphere exploration has mastered the key technologies of international cutting -edge, and will provide observation data for the response of the high -level atmosphere in the middle and high -level atmosphere of the pole area to the injecting of solar wind particles and the global atmospheric circulation interaction.

After the system was installed, Huang Wentao participated in the wintering mission of the year as the class leader of the scientific examination, and was responsible for the on -site observation of the radar. During the wintering, Huang Wentao both focused on the earth's atmosphere, but also the strong disturbance of the space environment such as the solar, magnetic storms, and sub -violence, and the latter could usually cause gorgeous aurora. "Aurora can often be seen in the clear night sky, which is also the best sky condition for laser radar observations. During the observation, the Aurora activity is also part of my work." Huang Wentao said.

"Witnessing the magnificence and agility of Aurora in Zhongshan Station is my most rare life experience." Huang Wentao told reporters that during the laser radar -booting observation, someone needs to take care and maintenance at the scene. He often observes the night shift at the laser radar on the edge of the station area for a long time, and he will also use a camera to shoot the magnificent aurora.

During the period before and after the Winter Festival, it was Huang Wentao's busiest. Sometimes he needed to take turns on duty with his teammates for several days. "This period is usually when Zhongshan Station has a low temperature throughout the year. The low temperature of more than 30 degrees Celsius plus the unique wind of Antarctica, any part of the body will quickly lose warmth, frostbite if you care about it." Huang Wentao said.

Due to the restrictions on regional factors, my country started late in the observation research of Aurora System, and the time to engage in high -altitude and atmospheric physics research in polar areas has been far behind the United States, Japan, Australia and other countries.In recent years, with the support of national key scientific and technological projects, my country's polar high -altitude and atmospheric physical observation and research capabilities have improved rapidly, accumulating a large amount of observation materials, and obtaining a series of scientific research progress.Behind these achievements, Huang Wentao's long duty and hardships of these Antarctic "night guards" are inseparable.Content source: i natural all -media
