On the deck, a group of people stood, all wearing thick coats, wrapped like penguins.
Normally, it would still be dark before dawn and everyone would still be sleeping, but now a lot of people came.
Obviously, everyone wants to get up to see the aurora.
The huge cruise ship passed through the ocean filled with ice floes, breaking into pieces of thin ice and leaving a clear water mark.
The Arctic Ocean is an ocean covered by sea ice. The perennial seawater accounts for about two-thirds of the ocean area. There are also a large number of floating ice and icebergs on the rest of the sea surface.
About half of the seawater here will freeze all year round, and the rest will melt in the spring and freeze in the winter.
The sea ice in the central area has even existed for 3 million years and is permanent sea ice.
The climate type is even more single. It can be simply summarized in one word: cold.
"Phew, it's so cold."
"It's too cold. What's the temperature now?"
"Thirty below zero."
"Only thirty? Why do I feel colder than yesterday?"
People who asked about the temperature were confused. It was already 30 a few days ago. Today it is even colder. Why is it still 30?
"That guy is an ugly country guy. What he said is Fahrenheit, and Celsius is already close to minus 35 degrees. Damn it, my nose is about to freeze off. Steven will definitely laugh at me when I go back."
"Damn, my thermometer isn't moving!"
"ha?"
On the deck, a man tapped his thermometer against the railing, making a sound like metal clashing.
The temperature on the thermometer didn't move at all, which made the man a little angry.
"The freezing point of kerosene is minus 30 degrees Celsius. It's frozen, so of course it's impossible to move."
The sound came from the direction inside the cabin. Everyone looked up and saw Bifang closing the door and walking to the deck.
"Hey, it's Mr. Bi."
"Mr. Bi, will you get up and watch the aurora too?"
"Any stories for us today?"
"I watched the video last night. It was amazing. I regret not meeting him earlier."
Everyone said hello one after another. In less than a week, everyone on the ship knew this young man, from the captain to the chef to the tourists.
Bi Fang nodded with a smile, came to the man who complained that the thermometer was broken, and leaned on the railing: "Generally speaking, there are three kinds of materials for thermometers, kerosene, mercury, and alcohol."
"The freezing point of kerosene is only minus 30 degrees below zero. If it is below this temperature, it solidifies and cannot be moved. In other words, the cold shrinkage effect is so small that it is almost invisible to the naked eye. The freezing point of mercury is minus 38.87°C, so it cannot be used.
"
"You can only bring an alcohol thermometer when you come to the North Pole, because it has a freezing point of minus 117°C and is adaptable to all low-temperature natural environments on the earth. Fortunately, you are not using mercury, otherwise it would be very dangerous in case of an explosion. However,
Thermometers rarely use mercury."
There are many differences between thermometers, the most common ones are thermometers and thermometers.
Thermometers are usually mercury, while thermometers are kerosene and alcohol. What they measure can be understood literally.
"Why?"
Someone shouted from behind.
Bi Fang raised his head: "Because mercury expands slowly when heated, it will not cool down quickly after being taken out of the body. It needs to be shaken to return to zero. Using it to measure temperature is simpler and more intuitive, and it can also avoid external temperature transfer.
errors caused."
"Kerosene and alcohol thermometers expand very obviously when heated, and change very quickly. They rise and fall quickly when they are cold or hot, so they are generally not used to measure body temperature. They are made into red ones and hung indoors to roughly monitor the weather and temperature.
"
Everyone suddenly realized.
"Did you get up so early today?" Bi Fang looked at the time and saw that it wasn't breakfast time yet.
Although the real polar night has not yet arrived, the unusually short daytime still reminds people to pay attention to time.
Perhaps the vast majority of people will not have the experience of the polar night, but it is conceivable that it is not easy to survive the polar night, and there are many problems, such as human biological clocks being disrupted.
A large part of the human biological clock relies on natural light.
Therefore, a very important way to adjust the rhythm is to eat. The meal times on the ship are fixed, and only three meals are free.
If you want to add food, sorry, you have to pay extra.
"They're all here to see the Aurora."
"It's so beautiful."
"Yes, it will be dawn soon, can you still see it?"
"It's available here during the day, of course."
"Mr. Bi got up early too."
"Yeah." Bi Fang nodded and pointed to the ice floe not far away, "I will disembark as soon as it gets light and find a good place."
It’s time to disembark!
Everyone was a little surprised, but not too surprised. Everyone knew that the purpose of Bi Fang's trip this time was to reach the northernmost tip of Greenland.
I just didn't expect it to come so quickly.
Half an hour later, the green belt in the sky was still there, a second ray of natural light slowly appeared from the horizon, the dark black curtain was lifted, and the fish belly white appeared.
A century ago, on the other side of the earth, on the Antarctic continent, a group of the bravest people in the world embarked on a life-or-death adventure.
On the left is the flame, on the right is the sea water, and in front is the dream and glory that I am pursuing hard in my heart.
A century later, a young man came to another node on the earth. Without carrying any supplies, he would challenge to survive here for one hundred days.
The cold wind howled.
This huge cruise ship, which was more than 70 meters long, once again smashed into an ice floe, and the sun hung obliquely on the bow of the ship.
The bow of the ship seemed to have scattered the most dazzling sun, leaving behind scattered white light that spread in all directions.
The shivering tourists raised their heads with squinted eyes. In front of them was a vast expanse of white. It was not a piece of white ice floes, but a continent, a vast and stretching pure white continent.
There are no trees, no grass, no living things.
There was only the endless cold wind, like a steel knife slicing open the face. There was no blood, and all the blood froze into blood-colored ice edges the moment it was about to splash out.
Many viewers couldn't help but touch their faces. The skin on their faces was almost numb from the cold. It wasn't until their warm fingers touched the skin that it turned into ice cubes that they realized that their faces had not been cut by ice blades.
, everything just now was just my illusion.
A familiar voice mixed with the sound of wind rang in their ears. Everyone heard it and ran away. Unexpectedly, the drone that seemed to be indestructible was already hanging above their heads.
"Looking back at the evolution of humankind, if our ancestors had not taken risks and imagined, and had not had the courage to innovate and sacrifice, they would not have used canoes to surf the sea and explore the infinite mysteries on the other side of the ocean."
"Human beings are curious and have the urge to take risks. Human beings take risks and light the torch of civilization."
"Adventure is not only found in nature's oceans and mountains, deserts and swamps, but also in densely populated cities."
"I am Bi Fang, a professional outdoor explorer. This time, we came to the North Pole."
