Why Pressure At The Bottom Of The Ocean Is High?

At sea level, the air that surrounds down presses down at 14.7 pounds per square inch. We don't feel it, because the body releases the same force pushed by the fluids in our body.

Dive deep into the ocean, you will encounter a noticeable change. You can feel an increase in pressure at your eardrums. This is due to the increase in hydrostatic pressure, the pressure exerted by a fluid on an immersed object. The deeper you go, the increase the pressure pushes you down. For every 33 feet, you dive deep, there is a change in the atmosphere by 1 unit.

pressure at ocean bottom,

The animals living deep, are experienced to live extreme pressure conditions. They have special features which help them to deal with these tough conditions. In the deepest part of the Atlantic, the pressure can reach up to 840 bars while the pressure at the challenger deep (Mariana Trench) can go up to 1000 bars or more. 

Whales, deep dive to almost 2000 meters to capture the squid. They breathe air, but their lungs are collapsible, so they don't get crushed when they go deep for more than 2 hours.

There are different techniques for the animals to survive at those depths, whether they are visiting or living there.

There is so much we don't know about the deep sea. But when scientists tend to study the sea animals that are surviving at these depths tend to die when they are brought to the surface. Which makes us don't know about the other remarkable features they possess.

Sea Turtles: The Endangered Species

Image
Sea Turtles have outlived almost all the prehistoric animals once they shared the planet. Marine turtles inhabit the oceans open waters and coastal habitats, feeding on jellyfish and other aquatic plants and animals. They are the live representatives of a group of reptiles that traveled our sea for more than 100 million years.  Importance of Sea Turtles These sea turtles have been living for more than 100 million years and maintaining a fundamental link in the marine ecosystem. They maintain the health of seagrass beds and coral reefs that benefit the valuable species such as lobster, shrimp, and tuna. Having outlived million years they can hold their breath up to five hours. They also transfer the vital nutrients from oceans to beaches and dunes. The seven extant species are The Green, Loggerhead, Kemp's Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback, which are endangered. Five of the seven species are found in tropical and subtropical waters. The other two sp...

What Gives More Oxygen on Planet Earth?

Image
Everybody knows that plants and trees produce oxygen for the earth. But, do you know that oceans and seas contribute more oxygen. Produced by marine plants, algae and single-celled organisms called phytoplankton. These may not be seen by the naked eye but produce more, which is not even close to the proportions produced by the trees and plants. The ocean produces oxygen as a by-product of photosynthesis, which converts sunlight and carbon dioxide and can use as energy. One type of plankton, Prochlorococcus releases tons of oxygen into atmosphere. So small, that can millions can be present in a single drop of water. It produces 20% of the oxygen to the earth biosphere, which is more than the rainforests on land combined. Scientists mention that a single cell can give oxygen for one in every 5 breaths we take. Calculating the amounts of oxygen on oceans may vary because of the change in climate conditions, geographic location and with the tides. It is also important to remember that the...

Experiencing Georgia Aquarium

Image
Hey there, I'm Mounika and I'm here to talk about the most magical and engaging place Georgia aquarium  No matter your age, everyone is a kid at Georgia Aquarium . Home to the most amazing aquatic animals, including beluga whales, whale sharks, manta rays, penguins, sea otters, dolphins and many more. Whether it may be dolphin show or sea lion presentation or entering the zone of Predators of the Deep, everything is amazing at Georgia aquarium. Filled with 11 millions gallons of water in seven permanent galleries making home to over 100,000 animals.  The Georgia Aquarium is divided into 7 sections: Coldwater Quest, Ocean Voyager, Tropical Diver, Georgia Explorer, River Scout, Predators of the Deep and Dolphin Tales. Ocean Voyager is the largest exhibit with 100-foot underwater tunnels and one of the largest viewing windows.  There's so much to see in Georgia Aquarium. I spent half a day roaming and getting mesmerized by the amazing creatures. Located in Downtown Atlanta a...
