A group of four people followed behind Fang Hong, walking towards the gentle slope of the ground, which was constantly lowering. Pen ~ fun ~ pavilion www.biquge.info

"98% of the entire Antarctic continent is covered by ice with an average thickness of 2,450 meters, as if wearing a big hat on the head, and is figuratively called the "ice sheet". Fang Hong: "From some perspectives, from some special places in Antarctica, you can directly enter the ice sheet, you can bypass the limitations of the equipment and directly take ice samples from tens of millions of years ago, which is of great significance for scientific research." ”

However, many people who have entered here so far have not taken the underground ice with them, and no one knows why.

In short, the scientific expeditions of various countries are said to be for the future of mankind, but they are very tightly covered with each other, and there is no such thing as providing materials to each other.

In other words, no one has ever obtained ice data, whether it is underground here or under the southwest ice dome, and no one knows the specific reason.

It's simple, try it yourself if you want to know.

The farther you go, the colder the air becomes.

"The so-called groundless wind is really groundless."

This is a very strange feeling, when the ground is cracked, the temperature will be close to above freezing, and after crossing an area, and going up, it will encounter a low temperature of minus twenty or thirty degrees.

It's as if air conditioners are installed at intervals in this large natural ice cave.

Due to the convergence of hot and cold air, the hot air floats up and the cold air sinks, and it is natural that wind is generated.

"It's a strange feeling, you can clearly feel the change in air temperature without a thermometer, it's like ......" Fang Hong thought for a long time, and held back a sentence: "It's the same feeling as passing under the main entrance of the mall." ”

Although the state strongly promotes that the air conditioning temperature in semi-public places such as shopping malls should not fall below 26 degrees, this policy is difficult to implement.

In the hot summer, the main entrance of the mall is full of people, hot air and biological heat sources - people constantly enter, it is difficult to stabilize the air temperature at a set temperature.

Therefore, shopping malls generally add central air-conditioning outlets at the entrance to make people feel like they have entered a new world from here.

It's also a way to attract customers, and if you're walking down a hot street and suddenly it's cool, you'll wonder if you want to go in and have a look, it's boring anyway. Go in and out again, only to find that you have no intention of going to the mall at all, but you have taken a whole bunch of goods with you.

"It's warm to walk through these foggy places." Fang Hong pointed to the place where the smoke came from the ground: "This should actually be pure water vapor, not volcanic gas, as for how it was produced, I don't know." ”

Professor Wang next to him gave an explanation: "The viscosity of the lava of Erebus Volcano is very high, and the gas is not easy to escape from it, so the venting of gas is generally to form huge bubbles to burst and excrete from the lava lake, and the ground fissure here is actually volcanic gas, but the sulfide content is very low, because the high temperature of the lava makes the water in it turn into water vapor, which gushes out from the vicinity of the fissure, and when it reaches the ground, it will also evaporate the water on the ground." ”

"When they reach the cold air, they quickly turn into solid crystals floating in the air, turning into visible water vapor. The gas of steam and water vapor is not the same gas, water vapor is a gas, while steam is a solid water that floats in the air. ”

Fang Hong interjected: "This was probably taught in junior high school physics class. ”

All water friends swiped the screen and complained: "Why don't you understand physical science." ”

"I ...... I...... I'm liberal arts. ”

Shuiyou: "What about the, you have to be in high school to score in liberal arts and science." ”

"Nima, Brother Gun is too shameless, how did you get into the nuclear energy major."

Professor Wang next to him smiled and gave his explanation: "It's very simple, because the nuclear energy major in college actually involves very little physics knowledge, but more architectural knowledge. And this is geological knowledge, and it's very out of the way. ”

Fang Hong raised his thumb: "It's still a professional who understands a lot." In fact, Fang Hong's geological proficiency has been pointed to LV6, but he still has not obtained this knowledge. It seems that compared with professionals like Professor Wang, LV6 is as fragile as scum.

"There seem to be traces of shrinking in the rift ahead, have you reached the end of the ice cave?"

Hua Bai: "I don't think so, the area of influence of Mount Erebus shouldn't be so small, right?" ”

From the conventional knowledge of volcanoes, in addition to the lava lake on the top of the mountain, the magma chamber should be extended in all directions, and under the volcano in Kenya, someone once set a record of 26 kilometers deep into the magma chamber.

For a volcano as large as Erebus Volcano, the underground magma chamber should have a far range of influence, and there should be a large number of terrain such as ground fissures in the entire mountain.

From the geology here, the basalt here has many bubbles where it is formed, and it cools very quickly, so it is more fragile than ordinary basalt, and it stands to reason that ground fissures should exist on a large scale.

"Who can tell, maybe it will be clear up if you go a little deeper here."

Qiu Qing put down some of the equipment: "Wait a minute, collect samples first." ”

Qiu Qing began to collect air, soil, fine icicles, and water dripping from icicles.

Fang Hong also stopped in place: "It stands to reason that in this climate, it is difficult for organisms to exist, but traces of organisms can basically be found on the bare land on the Antarctic continent, and there may be creatures on the bare land here." ”

Next to him, Hua Bai looked around and groped along the ice wall.

Everyone didn't pay much attention to Hua Bai's behavior, but they were all paying attention to Qiu Qing's collection of samples.

Truth be told, collecting samples is very important for post-analysis.

For scientists, they can determine what samples are more suitable for organisms to live and attach to.

This is also the reason why the collector who goes to the outer space is not valued, and all countries always want to develop manned spaceflight. Because there is no way for a computer to turn a machine into an experienced scientist.

Judgment is very important in science.

"We've been more than 200 meters deep into the ice cave, which is a very long distance if we are on the surface, and underground, we are almost in an environment with very poor visual conditions."

Just when Fang Hong reported the data to the water friend, there was a snapping sound next to him.

Then Hua Bai shouted in panic: "Ah! ”

Fang Hong turned his head and looked around, the powerful searchlight flashlight in his hand swept over, and the two quickly found Hua Bai back and forth.

Just at the heel of the ice wall, under an abrupt fracture, Hua Bai's half body was outside the ice wall, or on the surface, and half of his body was obviously under the surface.

It seems that Hua Bai was walking along the ice wall, but he didn't expect the ice wall in this position to be weak, so he leaned on the ice wall and fell.

"Is this a magmatic fissure? Don't see the fire? Fang Hong shouted: "Save people first." ”

Fang Hong didn't dare to make too many moves, the weak ice wall here was broken, what if the one next to it was also fragile, causing the ice wall to collapse?

Fang Hong strode forward, and then grabbed Hua Bai after a small sliding step.

Fang Hong was a little embarrassed after grabbing his clothes.

Because of the need to avoid the cold, the clothes everyone wears are very fluffy, and Huabai itself relies on his arms to insist on not falling, so the clothes cannot bear weight. Fang Hong grabbed Hua Bai's wrist with one hand and the other: "Is your foot empty?" ”

"Empty!"

"Do you feel the heat?"

"There's no heat, it should be about the same temperature as outside."

Not magma ground fissures? Is it a mountain cliff? It's normal for a mountain to have a cliff, but now the Erebus volcano is covered in ice caps.
