Why is it difficult to find the bodies of Chanchu victims?

With the Google Earth tool, we can easily see the location of the accident of Vietnamese fishermen in the recent storm Chanchu. Just type in the Google Earth search box 20.30N, 116.47E then Google 'earth' turns to that point and "zooms" in until it emerges on a small island with names as well as links related about it. It is Dong Sa Island, according to Vietnam, China called Dongsha Island, and English documents called Pratas Island. The island is currently under Taiwanese management, and there is a small airport and a hydro-meteorological station on the island. In another search we had beautiful pictures of this island. The island is like a diamond bead lying on a coral circle, in the air, looking like a ring, so beautiful.

Our fishermen some ships came into the coral to shelter the storm, others anchored outside.

The sea on the shore is a shallow sea of ​​less than 200 meters, but the outer sea, the southeast of the island is a very deep sea area, according to surveying maps, 200 - 2,000 meters deep. At the coordinates of 14.00N, 117.00E, 500 miles east of Quy Nhon city, the depth is -4.364m. Therefore, the fishing boats in this waters apart from the anchor, each ship equipped with a parachute, a 4 meter square cloth stretched, dropped into the sea acts as a parachute so the ship cannot drift whenever the anchor cannot drop to the bottom.

And it is this depth that makes us understand why the number of bodies found so little: 21/254 people were found. First of all, anyone who has a life jacket or a previous sense that ties himself into a plastic can, gas tank will be recovered. As usual, people who die without lungs overflowing will float, and the lungs that are overflowing with water will sink. Submerged for 3 days, now the body begins to decompose; In the intestine, the bacteria that break down vapors will cause the intestines to fill with air to begin 7 days floating on the water. After 7 days, the intestine will explode so that the gas will spill out, the body will start 9 days without floating and not sink. '3 sink 7 floating 9 floating' is therefore.

In the case of deep sea is different, the sunken body will not be able to float because when submerged to a certain depth, the pressure of water will cause the body to close down, the intestinal tube is also flat and easily torn, slightly It is caused by bacteria that are easily released from the bacteria and therefore cannot become an air sac to make the body float.

It has been a long time, the sea has returned to green, but by looking at the satellite images or photos of the aircraft on the internet, we still get excited when we see the location of the disaster on May 17. . Our fishermen are really good when they have reached out to the seas so far to catch. Accidents happening will certainly be drawn by the relevant industries, but what needs to be warned is that it seems to start having fishermen targeting the east coast of the Philippines, meaning completely on the Pacific Ocean. no longer in the East Sea. There are fractures creating the deepest pools in the world, such as Trech Mariana deep pools to 11.033m, or Philippines region, close to the east coast of the Philippine Islands with a depth of 10,057m. Heard there is a giant squid that is 2 meters long!
