What do you know about ground blue holes?

 

We certainly know more about the moon's surface than our oceans, but now a mystery of the ocean floor is about to unravel.

A group of scientists and expert divers are ready to add new information to the human ocean.

A team of experts from the Mutt Marine Laboratory, the Florida Atlantic University, the George Institute of Technology and the US Geological Survey are exploring a "blue hole" hidden beneath the ocean floor in the Gulf Coast of Florida.

Blue holes are actually sinkholes formed in underwater rocks that are well below the seabed floor.

This blue hole in Florida has been dubbed 'Green Banana' which is located 155 feet below sea level while the depth of this hole is 425 feet.

Emily Hall, program manager for the Mutt Marine Laboratory, told CNN: "We were actually looking for the hole in the spring, but we had to stop because of Corona."

The main purpose of this campaign is to know more about the 'Blue Holes' which are present in the oceans of the world but not much is known about them.

Last year, another blue hole, 30 miles off the coast of Sarasota, Florida, was reached by Ambergeck, 113 meters below sea level and 237 feet deep.

While examining the Amber Jack Hole, scientists collected 17 samples of water and 4 samples of rocks, while also discovering two dead small toothpicks.

The fish were found in the lower part of Surak, where the oxygen level in the water was low, which helped them survive.

According to Emily Hall, "a lot of people compare it to going into space. We don't know what we'll find there, but we'll continue our search."

Jim Clutter, a senior scientist at the Moat Marine Laboratory, said that underwater holes exist all over the world but their number could not be determined. They are usually found in parts of the world where a type of limestone, Karst, is found. Is.

Some blue holes are so deep in the ocean that they were discovered with information from divers and fishermen.

Why are these blue holes unique?

These holes take the form of hotspots for environmental diversity that attract marine life such as sharks, sea turtles, corals and others.

In Jim Cutler's words, they are like an oasis on the barren surface of the ocean, but the oxygen level in their bottom is significantly lower and they are unfavorable to marine life.

"One of the most amazing things we've learned about these holes so far is the huge amount of nutrients," said Emily Hall.

The carbonate chemistry of these blue holes is also unique, and the more knowledge there is about it, the more scientists expect it to give them an opportunity to learn more about the global carbon cycle and marine acidity linked to climate change.

Scientists also want to know the relationship between these blue holes and the water found in groundwater.

Analysis of water samples taken from the ambergris hole revealed that they contained radium and radon isotopes, which are found in groundwater.

It is also clear from a biological point of view that there are many unusual things in blue holes.

Checking out greening is a big challenge

Getting deeper into the ocean is no less of a challenge.

According to Jim Clutter, "When you go deeper and stay there longer, you can have a variety of problems, because the body's tissues begin to accumulate large amounts of nitrogen, while slowing down to get back up." Demonstration is done so that nitrogen does not start coming out of the blood in the form of bubbles.

Nitrogen has a sedative effect on the body and also affects the diver's eyesight, while another concern is the lack of oxygen in the blood which can lead to toxic effects.

While exploring the amberjack hole, Jim Clutter reached a depth of 300 feet in 7 minutes, but the process of returning to the surface was completed in about an hour. It will take 2 hours.

However, the discovery of blue holes is a unique scientific challenge of its kind, and according to Emily Hall, we do not know what we will discover there.

Research based on such unpredictable results is considered rare in modern times because people expect specific results in most fields but no one finds what is found in blue holes.

According to Jim Clutter, science is based on small steps.
