It was precisely because the narwhal had such a strange and long horn that this whale was almost killed to extinction for a long time.

Just like an elephant's ivory, an innocent man is guilty of possessing the treasure!

But the situation is much better now. Under the strong protection of various countries, this animal that was once on the verge of extinction has now regained its prosperity.

Compared to the shabby Nuuk, whale watching in the open sea is undoubtedly much better. The only pity is that we did not see the largest northern blue whale when we went out to sea to watch whales today.

But the day was quite enjoyable. At least Yang Jing and Gege had a lot of fun, and that was enough.

The next day, Yang Jing and Gege slept until the sun was high in the sky. It was really high in the sky. In Nuk, the sun came out at about 3:00 a.m., so it was about 7:00 a.m., wasn't it high in the sky?

Lin Dan did not get up. This guy went back to the boat last night and took down an eye mask. Finally, he had a good sleep.

Yang Jing and Gege did not disturb him, letting him sleep a little longer. After breakfast, Yang Jing and Gege took the four bodyguards to the Katuaq Cultural Center, and then visited the Nuuk Art Museum and the Greenland National Museum.

It was not until after four o'clock in the afternoon that Yang Jing received a call from Andre, who said that they would leave that evening and asked them to come back.

After touring this small capital city for the most part, the two men rushed back to the dock, boarded the Blue Whale and continued on their journey.

The huge Blue Whale is sailing in the Davis Strait. To the east is Greenland, the world's largest island, and to the west is Canada's Baffin Island, the world's fifth largest island.

In fact, once you pass the Labrador Sea, the world’s second largest archipelago, the Arctic Archipelago, appears to the west of this route.

As the second largest archipelago in the world after the Malay Archipelago, the Arctic Archipelago is not as fragmented as the Malay Archipelago. This archipelago located at the northern end of the North American continent is more famous for its large islands. For example, Baffin Island ranks fifth in the world in terms of area, while Victoria Island to the west of Baffin Island ranks eighth in the world in terms of area. Ellesmere Island, the first destination of Yang Jing's voyage, is the tenth largest island in the world.

This vast archipelago was originally part of the North American continent, but after the end of the Quaternary glaciation, the sea level rose, causing these islands to separate from the North American continent, forming a large area of ​​fragmented islands on the sea.

The further north you go, the longer the sun stays in the sky. Especially after crossing the Arctic Circle, the sun in the sky is like an indestructible cockroach, always hovering above the horizon. Even if it falls below the horizon, it will reappear in the blink of an eye. The further north you go, the more severe this phenomenon is. This is the famous polar day phenomenon.

At the same time, the further north you go, the lower the temperature. Even though it is already the hottest season of the year in the south, there is still no trace of summer here.

After the Blue Whale sailed out of the Davis Strait and entered the Baffin Bay, ice appeared on the sea surface.

In fact, the waters north of Baffin Bay, including the Smith Strait that we are about to pass through, are only navigable in August and September. There is still ice in this sea area in July.

Fortunately, the sea ice was not thick at this time, and the Blue Whale was an AC1-class icebreaker, so it was easy for it to deal with the ice that was only a few centimeters thick. Even if it continued to sail north, the most it could do was to slow down the Blue Whale.

When the Blue Whale was sailing on this route, it always tried to stay as close to the center of the route as possible. After all, this was already in the Arctic Circle, and sailing was a relatively dangerous thing, especially in the summer.

Whether it is the glaciers breaking off from Greenland or Ellesmere Island, they will form icebergs that can only be seen a little bit. Driven by the ocean currents, these icebergs, which can be called killers of giant ships, will continue to swim along the coastline. Once a ship encounters this thing, the end will be very tragic.

The famous Titanic was unfortunately encountered these giants and then sank.

Although the Blue Whale is an icebreaker, it also keeps a distance from such giant ship killers. Fortunately, the Blue Whale is a scientific research vessel with extremely modern equipment. The iceberg radar on the ship can detect icebergs hidden below the sea level from a long distance, thus issuing an alarm to remind the captain to avoid them.

After entering Smith Sound, the ship speed has dropped from 14.5 knots to 10 knots, and finally to the current 7 knots.

There is no way. The ice in Smith Strait is already 20 centimeters thick, and some rampaging icebergs appear from time to time. Compared with Davis Strait, which is 300 kilometers at its narrowest point, this strait is simply too narrow. The widest part of this narrow strait is only more than 100 kilometers, and the narrowest part is less than 30 kilometers.

When sailing in this strait, you must be extremely careful.
