Why is Lake Nuwok a double decker lake?

In the northern part of the Arras Peninsula in North America, on the Cape Barrovo in the Arctic Circle, there is Lake Nuvok. The lake is divided into two layers, the upper layer is fresh water, and the lower layer is slightly bitter salt water. In any case, there is a clear boundary between the freshwater and the saline aquifer, which indicates that the water of the lake is not mixed up and down.

Due to the influence of cold Arctic air, for most of the year, Lake Nuwok is covered in snow and ice, and the freshwater layer, which is more than 2 meters thick, is frozen into a large block of ice. According to scientists, it is believed that the lake was formed as a result of the rise of the bay. To the north of it is a long and narrow strip of land, like a separating it from the sea to the north.

Due to the abundant snow in winter, a large amount of snow melts in the spring into this "pocket", because the cold climate on the lake never mixes with salt water. Sometimes, the northern waters are stirred up by storms at sea, climb over the narrow "causeway", and fall into the lake, because the specific gravity of the sea water is greater than that of fresh water, and they all sink to the lower layer of the lake. As a result, the water at the bottom of Lake Nuwok is saltier than the water in the neighboring oceans.

The most interesting thing is that the two layers of water in the double-decker lake are full of different creatures. Flora and fauna that grow and breed in the upper layers of the lake can only be found in freshwater lakes and the rivers of the peninsula; In the lower part of the lake, the flora and fauna found are typical marine life in the Arctic Ocean.

Lake Nuwak is located on Point Barrow in northern Alaska, United States. 180 meters long and 180 meters deep. The lake has two layers of water, the upper layer is fresh water and the lower layer is salt water.

The lake is clearly divided, and the dividing line is just a meter underwater. Lake Nuwak is located on Point Barrow in northern Alaska, United States. 180 meters long and 180 meters deep.

The lake has two layers of water, the upper layer is fresh water and the lower layer is salt water. The lake is clearly divided, and the dividing line is just a meter underwater.

The local Eskimos have known about this strange phenomenon in Lake Nuvok, but the reason has not been found. Now, scientists explain it like this: .Lake Nuwok was originally a low-lying area, and strong winds used to blow up nearby seawater, fish and shrimp into the depression.

Later, when the snow melts and flows into the lake, it suddenly encounters cold air, and the surface of the lake is frozen, blocking the wind, and it is difficult to mix the low-density fresh water above and the dense seawater below. So it becomes a peculiar double-decker lake. The water of this lake is divided into two layers, and the dividing line of the lake water is 1

8 meters away. The upper layer is freshwater, and freshwater fish live in the water; The lower layer is saltwater, and it is inhabited by marine life. So, why is Lake Nuwok so clearly classified?

Scientists explain that Lake Nuvo turned out to be one. A low-lying area where strong winds have blown up nearby seawater, fish and shrimp and thrown into the depression. Later, after the ice and snow melted, it flowed into the lake, and suddenly encountered cold air, and the lake surface was frozen, blocking the blowing of the wind, and the dense sea water below could hardly mix with the less dense fresh water above, so it became a peculiar double-decker lake.

Why is this amazing phenomenon occurring when the waters of Newark Lake remain clearly demarcated? What is it that causes this situation in which the disparate water layers do not "invade" each other? Let's talk about why Lake Newark is a double-decker lake.

Newark Lake is formed by the rise of the bay, and because of the abundant snowfall in winter and the cold climate on the lake, fresh water can never be mixed with salt water, and the proportion of sea water is greater than that of fresh water, so it sinks to the bottom of the lake. Moreover, Lake Nuuk is located in the Arctic Circle, and the freshwater layer more than two meters thick above Qin's eyes often freezes into ice and cannot flow. In this way, the interface between freshwater and seawater is particularly distinct.

In Barrow Point, northern Alaska, USA, there is Newark Lake, which is 180 meters long and about 6 meters deep, and there is a narrow strip of land in the north that separates Newark Lake from the Arctic Ocean. The lake has two layers, upper and lower, maintaining a clear dividing line: the upper layer is freshwater, where freshwater fish live; The lower layer is slightly bitter saltwater with marine flora and fauna.

The creatures in the upper layer and the creatures in the lower layer do not interact with each other, and each lives in its own waters, so it is called the "double lake".

Through research, scientists finally came to the conclusion that the lake was originally formed by the rise of the bay, which was earlier a low-lying land, and its northern part was a narrow strip of land, like a levee separating it from the sea water in the north.

Due to the abundant snowfall in winter, a large amount of melted snow water flows into this "pocket" in the spring, and because of the cold climate on the lake, this fresh water can never be mixed with salt water. Sometimes the northern sea is stirred up by a storm at sea, climbs over the narrow "causeway", and pulls into the lake, and the specific gravity of the sea water is greater than that of fresh water, so it sinks to the bottom of the lake.

As a result, the water at the bottom of Lake Nuuk is saltier than the sea water in the neighboring oceans. Moreover, the freshwater layer in the upper part of Nuuk Lake, which is more than two meters thick within the Arctic Circle, often freezes into ice and cannot flow. In this way, the interface between freshwater and seawater is particularly distinct.

Lake Nuwok is located in the northern part of the state of Alaska, United States. The lake has two levels: the upper layer is freshwater, where freshwater fish live; The lower layer is saltwater, which is inhabited by marine life, and the dividing line of the lake is meters below the surface of the water.
