Live Wilderness Adventure - Chapter 647 3 days without food

The sun rises, and the spirit is full of energy.

Feeling the rise in temperature, Bi Fang felt that all the cells in his body were stretched out.

In the distance are white undulations, indicating that he is heading in the right direction, that is, he is heading towards the interior of Greenland.

Because there can be no ups and downs on the ice sheet, it must be a mountain range.

"If you choose a target as the direction of travel, after reaching that target, you have to re-establish a new target."

"In a polar environment, it's very empty, there are almost no characteristic objects, and it's important to remember a certain characteristic that you can see on the horizontal plane, but that doesn't mean you can get there any time soon."

Wangshan runs dead horses, the old saying warns against this.

You see the mountain, but all the horses run away, and they may not be able to reach it.

“It might be 100 kilometers away. The captain of the cruise ship shared with me an experience he once had while walking on the Greenland ice sheet and seeing a black object in the horizon line for weeks. During their trip, they passed icebergs and coastlines and saw nothing, and that was the first time they saw a small black spot."

"The captain at the time was so excited about seeing this different object, he set up camp, and talked eagerly about the mountain that he would be able to reach tomorrow morning. After two days of walking, it's still there!"

[Don't say this kind of embarrassing thing, okay? 】

[Ah, it's the captain! 】

[Is the captain also watching the live broadcast? 】

【Aren't you afraid of hitting the iceberg without staring at the boat?】

[Dear, I have a first mate, a second mate, that is the guy who really does the job]

【Good guy】

[polite first mate]

Bi Fang drank his last sip of water, squatted down and started to chisel ice.

"I drank a total of four pots of water these days, about two pots a day, and I didn't drink too much. Drinking water is a part of metabolism, and it will take away your body's energy, so if it's not extreme, just keep All you need is moisture.”

"One of the things that I feel is obvious is that the salty taste in the water is becoming less and less obvious, and here it is..."

Bi Fang chiseled a piece of ice, put it in his mouth, spit it out, and said with a smile: "There is basically no salty taste, which shows that the ice age here is quite old."

Imagine Chinese Network

The audience is a little surprised, what is the reason for this?

[I always thought that ice was Danshui, why is there salty ice? 】

[Indeed, I only remember that I learned before that the icebergs in the north and south poles are all Danshui, and there are many more]

The Antarctic and Arctic glaciers are the world's largest reservoirs of Dan water, where 70% of the world's Dan water is stored.

This is probably everyone's impression, is Danshui salty?

"You don't understand the real reason why glaciers are Danshui. The icebergs at the north and south poles are indeed Danshui, but the reasons for their formation are different, which also lead to some other differences."

"The Antarctic region is a continent. The specific heat capacity of land is much smaller than that of water, and the ability to store heat is weak. The heat obtained in summer is quickly radiated away."

Bi Fang poured crushed ice into the kettle and explained.

"The annual average temperature there is about -56°C. At low temperatures, the water produced by the water cycle mainly exists in the form of rain or snow, and the freezing point of water is 0°C, which can ensure that snow does not melt all year round at low temperatures."

"Even in summer, a portion of the snow melts and freezes very quickly, so in the ocean around the Antarctic continent, there's a lot of ice floating around, forming huge icebergs."

This audience understands well.

Danshui in Antarctica, because of natural evaporation, turned into snow, and then dissolved into ice. The whole process did not come into contact with any salt, and it naturally became a Danshui iceberg.

"In contrast, the Arctic region has a small land area and is mostly the Arctic Ocean. Due to the large heat capacity of seawater, it can absorb more heat, and the heat dissipation is relatively slow, so the annual average temperature there is higher than that of the Antarctic, plus Warm current, around 8°C."

"The freezing point of seawater is lowered due to various salts. At the same time, the solubility of seawater at low temperatures will also decrease. High-temperature seawater has higher salt content. When seawater freezes again, the salt will be transferred to relatively high-temperature seawater. So the seawater that freezes becomes 'Dan Shui' and the salt precipitates out in the form of crystals, causing a drop in the salt content in the glaciers that form."

"As a result, there are fewer glaciers in the Arctic than in the Antarctic, and the vast majority are stored in Greenland."

"The former is a natural distillation that directly becomes Danshui, which is a direct qualitative change, but the latter is the precipitation of salt due to various reasons, which is a qualitative change caused by a quantitative change. Since it is a quantitative change, there will naturally be a process. went through this quantitative process.”

"The Eskimos living in the Arctic ice sheet rely on this method to obtain a certain amount of water resources, which also leads to higher salinity in the frozen sea area or the ocean near the sea ice.

"At my feet, the qualitative change has been completely completed, the salt has completely separated out, and it has become a real Danshui. What I drank before can be regarded as salt water with a little salt~www.novelbuddy.com~ Although it is salt water, its salinity is higher than The seawater is much lower and can be used for hydration."

[Strange is only increased. 】

[I feel like I learned something amazing again]

【Geography is amazing】

"In fact, a very interesting phenomenon occurs when sea water freezes, that is, death icicles."

"The temperature at the north and south poles is very low. Sometimes the temperature of the sea surface will drop to a low temperature of minus tens of degrees Celsius. At this time, the sea surface will start to freeze. An icicle continues to extend downward, and the surrounding sea water does not freeze due to the change in density after it reaches the freezing point."

"Therefore, the 'Icicle of Death' was born. It can be seen from the bottom that an icicle extends from the sea surface to the bottom. When the temperature is extremely low, the freezing occurs in a very short period of time, and it is touched by the icicle. The marine life that arrives will be frozen in an instant, so this phenomenon is called 'death icicles'."

【What magic magic? 】

[Fang Shen, I want to learn this! 】

[Fang Shen: If I knew this, I would have gone to the cosmos long ago.]

"Now we are walking on the ice sheet of Greenland. The thickness of the ice sheet can even reach several thousand meters, which cannot be penetrated by manpower at all. The known average thickness is more than 2,000 meters, and the thickest place is even more than 3,400 meters. 100 meters."

One after another astonishing data popped out of Bi Fang's mouth, shocking the audience.

Who has seen the ice layer after a few kilometers?

In such a shock, Bi Fang never reached the mountain range in front of him. As a last resort, he dug another snow ditch to cope with it for one night.

It was not until the evening of the third day that Bi Fang really touched the first rock he came to the island.

And so far, he has not eaten for three days.
