Murderous Sable Island

  Lost on Sable Island
  On the morning of August 29, 1593, the British expedition ships Joy and Squirrel, part of England’s Sir Humphrey Gilbert expedition, were sailing in the Atlantic Ocean ships returning to England from the North American continent.
  When they came to the vicinity of Sable Island, a thick fog suddenly appeared on the sea, and visibility was very low. The captain of the “Joy”, Richard Clarke, had a dispute with Sir Gilbert because of the route. Sir Gilbert insisted that they should land on Sable Island, but Captain Clark believed that they were not familiar with the island and should not Landing in this bad weather.
  In the end, Captain Clark obeyed Sir Gilbert’s order and drove the “Joy” close to Sable Island. However, they never thought that this seemingly ordinary island actually hides murderous intentions. When approaching the island, the “Joy” ran aground! To make matters worse, everyone found that the stranded ship began to sink, and the sinking speed was getting faster and faster, as if being sucked into and swallowed by a large monster.
  Captain Clark ordered the sailors to quickly lower the lifeboats and escape the sinking “Joy” as soon as possible. Although their escape speed was already very fast, the ship sank so fast that only 17 of the 102 crew members including the captain managed to escape, and the rest and all the supplies on board were lost to Sable Island. devoured”. The “Squirrel” was able to escape due to its shallow draft.
  Crazy “boat eating” mode
  After that, Sable Island seems to have started a crazy “boat eating” mode. From the sinking of the “Joy” to 1947, there were more than 350 recorded shipwrecks on Sable Island, with an average of at least one shipwreck per year. In the most serious shipwreck, more than 500 people died. However, a ship about 100 meters long and weighing 5,000 tons can be completely “eaten” by Sable Island within two or three months. What’s even weirder is that a few years after the “Joy” sank, when a ship passed by there again, it was found that the island had moved hundreds of meters to the east, and a few years later, it had moved another few hundred meters to the east. Meter!
  All kinds of weird phenomena make Sable Island a nightmare for sailors, so it is called “Shipwreck Island”, “Ghost Island” and “North Atlantic Cemetery”. And some people suspect that the island is alive and may be an alien monster! Is Sable Island a giant alien monster? Why are there so many shipwrecks there? why does it move?
  Today’s Sable Island is located about 300 kilometers southeast of the east coast of Nova Scotia, Canada. The island is about 40 kilometers long and 1.5 kilometers wide. It is a crescent-shaped island. This island has a white sandy beach. Although there are no trees or shrubs on the island, some places are covered with grass. Herds of wild horses sometimes run freely on the island, and sometimes stop to graze. Seals in the breeding season will also be on the beach. reproduce offspring. There are houses in the higher ground in the center of the island, and there are lighthouses on the east and west sides of the island. This looks like an ordinary island.
  However, when you walk on the beach, the wreck of the ship that reveals the sand from time to time and disappears in a few days will let you see the other side of the island and warn you to stay away from the beach! So why do ships run aground and sink on this island so often?
  Thick fog and huge waves
  at sea are one of the important reasons. According to records, the island is only sunny in July, and the island is often hidden in fog at other times, which is related to its location. Not far from Sable Island, the Labrador Current meets the Gulf Stream. The Labrador Current, a cold ocean current, and the Gulf Stream, a warmer ocean current, have different densities, so instead of peacefully merging with each other, they collide. Just as low-pressure and high-pressure air masses in the atmosphere meet, these ocean currents form “fronts,” or boundaries. While the air above a warm current is warm and contains water vapor, the air above a cold current is cold, so when the warm and cold air meet, the warm water vapor condenses into tiny particles, forming fog.
  The dense fog at sea can be said to be a terrible “blocker” for people who sailed at sea before the 1940s. This is because the navigation technology at that time was relatively backward, and the main instrument for determining the position of ships at sea was the sextant. The sextant is mainly composed of a small telescope, a semi-transparent and semi-reflective fixed plane mirror (horizon mirror) and a movable mirror (index mirror) connected to the indicator. This instrument determines the latitude and longitude of the ship’s position by observing the angle between the sun or other celestial body and the sea level or horizon at a certain moment. In clear weather, this instrument can accurately measure the position, but in dense fog or cloudy weather, it is useless. Many ships crashed into Sable Island because they got lost in the thick fog.
  In addition to the dense fog, the storm and huge waves near Sable Island were also surprisingly large. About 100 years ago, after a storm, storms and high waves pushed the northern coastline of Sable Island back inward, creating a harbor. Years later, storms and huge waves blocked the entrance to the port with sand, and the original port became a saltwater lake about 4 meters deep. Storms and waves can not only change the face of the island, but also destroy everything on the island. Buildings and facilities used by rescue workers on Sable Island are regularly washed away.
  The storms and huge waves of Sable Island are actually a masterpiece of the Labrador Current and the Gulf Stream. The Gulf Stream is warm and powerful, creating conditions for storms to form. Near the surface where the Gulf Stream and the Braddo Current meet, warm, moist air rises high into the air and forms an area of ​​low pressure below, while cooler air, controlled by the Labrador Current, sinks and flows into the low pressure area. The cold air is heated by the Gulf Stream in the low pressure area and rises again. This cycle goes on and on, and the moisture in the air continues to form clouds. With the help of the earth’s rotation, the clouds began to rotate, and the speed became faster and faster. At the same time, the clouds continued to grow, and violent storms on the sea formed. Many ships ran aground due to the inability to control the direction due to the storm.
  In addition, with the help of waves, Sable Island is also good at “invisibility”. The highest altitude of Sable Island is only 34 meters. There are only some low sand dunes on the island. Standing on the beach on one side of the island, you can almost completely see the beach on the other side. When the waves are rolling and visibility is not very good, the island is almost hidden from the waves.
  Even in clear weather, Sable Island is not easy to spot. Sea water absorbs the most red light and transmits the most blue light, so sea water looks bluer. However, due to the different scattering of light by suspended particles in different sea areas, the color of the sea water gradually becomes lighter from dark blue from the far sea to the near-shore waters, and the sea water near the estuary with more sand content looks light green. Sable Island is surrounded by shoals made of white sand and blue-toned coral reefs. Underwater, these parts will scatter more blue light in the sunlight because they are close to the sea surface, so the sea area is light blue and greenish. In the era when navigation technology was relatively backward, it was sometimes difficult for sailors to judge whether there was a shoal through this subtle color change.
  It is precisely because of the superb “invisibility” of Sable Island that many ships are “bitten” by it without paying attention, just like being stuck in a swamp, and finally disappear completely in the sand.
  An island that moves
  Sable Island not only likes to “eat boats”, but it is also moving, which makes people feel incredible. About 90% of the islands on Earth are volcanic islands, which are always firmly anchored to the seabed. Unlike Sable Island, it is not volcanic and moves. So why does the island move?
  Some geologists believe that Sable Island moves because the waves are pushing it! This is incredible, how can a wave push an island? Geologists believe the waves “move” Sable Island by carrying and bringing sand away. They believe that the interaction of the Labrador Ocean Current and the Gulf Stream continuously pushes the sand and rocks on the seabed together to form a huge sandy crescent-shaped dam, and Sable Island is the highest point of this giant dam out of the sea. point. Because the sea around Sable Island is often stormy with strong winds, the sand on the west coast of the island is constantly being washed away, some of it is washed away, and some is washed to the east coast of the island—— This cycle continues, making Sable Island seem to “move”.
  In the process, part of the sand from Sable Island was washed away, causing it to gradually shrink in size. According to 16th-century charts, Sable Island was 370 kilometers long and 300 kilometers wide, much larger than it is today. However, geologists have also discovered that although the sand on Sable Island has been losing, the ocean currents on the bottom of the sea are also continuously replenishing it with new sand. Therefore, it can be speculated that the island will not disappear “walking and walking”.
  However, this is only the opinion of some geologists. More evidence is needed to answer why Sable Island can move and how it was born.
  Nowadays, navigation technology has made great progress, and ships are safer at sea. There have been no serious shipwrecks near Sable Island since 1947. However, every time a ship passes by Sable Island, the radio beacon will still issue a warning that lasts for about 1 minute: “You are passing near the ‘North Atlantic Cemetery’ near Sable Island.” In recent years, more and more scientists have begun to pay attention to this They studied the coastal erosion of the island and the changes in the sand dunes on the island, hoping to conclude a method to prevent the coast from being eroded. Sable Island not only provides people with mysterious legends, it can also contribute to the protection of the environment.
