Chapter 329: Sargasso Sea
Panama's economy is supported by this canal, and its land area is not large, and after Panama, six people will reach Galle}
It's not too far from Bermuda, and more than a thousand kilometers north through the Florida Peninsula is the Bermuda Triangle.
After flying out of Florida, the vast ocean appeared again under my feet, and only half an hour later, scattered seaweed appeared on the surface of the ocean.
As we went deeper, more seaweed appeared below, growing together in patches, floating above the ocean, and the density was quite high, and in some places it was so thick that it was like a swamp, barely enough to hold the weight of a man.
The Sargassum Sea has arrived.
"This sargassum sea surrounds Bermuda, and we're in the Bermuda Delta."
There was nothing but a large area of seaweed under their feet, and the six people landed, and they felt the magic of this sea area.
Ma Tianyuan leaned over and picked up a handful of sargassum, brought it to the front and analyzed it carefully, He Qiliao saw that he was looking at it seriously, so he asked curiously:
"I said, old horse, what are you doing here? Is there anything peculiar about this seaweed? ”
Ma Tianyuan suddenly showed disdain: "When the university asked you to study, you wanted to 'herd cattle', and now your shallow problem has been exposed!"
Let me tell you, this Sargasso Sea is not simple, it can be said that half of the magical legends of the Devil's Delta are derived from this Sargasso Sea. ”
Seeing that he was cautious, several people gathered around, and Ma Tianyuan was even more proud, so he pointed to the surrounding sargassum and said:
"The Sargasso Sea, also known as the Sagasso (Portuguese for grape fruit) Sea, is a shoreless sea in the Atlantic Ocean, roughly between 20~35°N latitude and 35~70°W longitude, covering about 500~6 million square kilometers of water.
The Sargasso Sea is basically located in the Bermuda Triangle, but it is not actually a sea in the strict sense of the word, but a special body of water in the Atlantic Ocean.
The Sargasso Sea is a "sea within an ocean" that is separated from the North American continent by a wide sea to the west. The other three sides are vast oceans. So it is the only sea in the world that does not have a coast, so there is no clear demarcation line.
Sargassum is the largest algae and the only algae that can grow on its own in open water.
The plant does not grow in coastal rocks and nearby areas, but floats in the ocean in the form of large "rafts", where it absorbs nutrients directly from the seawater and spreads by splitting into patches and continuing to grow independently.
According to the survey, there are eight species of sargassum in this sea area**, and two of them are overwhelmingly predominant. The salinity and temperature of the Sargasso Sea are relatively high, because it is far away from the mainland and mostly under the subtropical high pressure zone, with little rain and strong evaporation.
The high water temperature is due to the influence of warm ocean currents, the famous gulf current pushes eastward through the northern Sargasso Sea, and the northern equatorial warm current flows westward through the southern part of the Sargasso Sea. The movement of the above-mentioned currents causes the sargassum currents to slowly rotate in a clockwise direction.
Why does it have such a scary name? Since ancient times, almost none of the ships that strayed into this "green ocean" can "return to Zhao", in the era of sailing ships, I don't know how many ships, because they strayed into this strange sea area, they were entangled by sargassum, and the people on the boat were exhausted because of fresh water and food, so people called this sea area "the graveyard of the ocean".
The first to enter the sea was Columbus, who was besieged for almost a month, and finally managed to escape with the help of the entire crew.
In the eyes of navigators, the Sargasso Sea is a desert at sea and a ship's graveyard. In this empty, dead sea, there are hardly any edible fish fish, sea turtles and the occasional whale seem to be the only living beings, in addition to the single-celled algae.
In the tales of legend, the Sargasso Sea is described as a giant trap in which passing ships are caught by magical seaweed, trapped in the seaweed, leaving only the bones of sailors and the wreckage of ships.
The Bermuda Triangle, the most famous and mysterious area in this sea, pushes these legends to the extreme.
Thanks to the joint efforts of oceanographers and meteorologists, the "eerie tranquility" of the Sargasso Sea and the reason for the inexplicable trapping of ships have now been identified.
It turned out that this 3 million square kilometer oval sea area was surrounded by four ocean currents.
The interaction of the Gulf Current to the west, the North Atlantic Stream to the north, the Canary Stream to the east, and the North Equatorial Current to the south causes the Sargasso Sea to flow slowly in a clockwise direction, which is why it is unusually "calm".
It is for this reason that the ancient ships that relied on the help of the wind and ocean currents to falter in these seas.
As a result, the problems of high salinity, warm seawater, and low plankton in the sargasso sea have also been solved.
While the seaweed in the Sargassum Sea has proven not to be the magic algae that blocks ships from moving forward and devours seafarers, the mysterious aura that hangs over its head has not disappeared. ”
"Oh, it's a still sea! So a lot of things are scared out of human beings themselves. Finding the reason is actually not so scary. ”
He Qi Liao laughed, and also grabbed a handful of seaweed and watched there. It didn't take long for the girls to discover the beauty of the sea: the water was so pure and quiet, as clean and transparent as a piece of jade.
"This is also normal, the Sargassum Sea is the most transparent sea in the world, and its water quality is the highest in purity and quietness."
"Impossible, right?" Ma Tianyuan's statement surprised everyone, isn't there seaweed here?
Ma Tianyuan smiled:
"It's true. The most distinctive feature of the Sargassum Sea is its transparency, which is recognized as the clearest sea in the world.
The Sargasso Sea is far from the estuaries of rivers, has very little plankton, and the water is turquoise and blue, with a transparency of 66. 5 meters, and individual sea areas can reach up to 72 meters. Therefore, sargassum is the most transparent sea in the world.
Generally speaking, tropical waters have a high level of clarity of up to 50 meters, while the Sargassum Sea has a transparency of 66 meters, and there is no other ocean in the world with such a high level of transparency.
Let me explain to you what it means to have a clear sea. It refers to a white round plate with a diameter of 30 centimeters, which is sunk vertically into the water in a place where direct sunlight cannot be exposed to it, until it is invisible.
The Sargassum Sea, near the Bermuda island group in the North Atlantic, is recognized as the clearest sea in the world, with a transparency of 66. 5 meters, and in some sea areas, transparency reaches 72 meters.
Whenever it is sunny, put the photographic film at a depth of more than 1,000 meters, and the negative can still be photosensitive. This is beyond the reach of any other marine area.
So you can't imagine it, this devil's sea is the cleanest sea in the world. ”
