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.

Antarctica Sea Ice Mystery? The Truth Behind the Enormous Ice Gap

Image
Scientists have discovered evidence for the open-ocean polynya formed over the Maud Rise, in the Wendell Sea, during the winters of 2016-2017. The study reveals the key process on how the polynya was able to form and persist for several weeks. The team of researchers from the University of Southampton, the University of Gothenburg and the University of California San Diego studied the Maud Rise polynya. They found that the polynya was brought on by interactions between the wind, ocean flow and geography resulting in vertical missing of the heat and salt towards the sea surface. Polynyas are openings in the winter sea ice that act like giant vents, exposing the warm water below to the freezing air above. Coastal Polynyas are regular visitors along the Antarctic coast where strong winds push sea ice away from the land, creating open water. Open-Ocean Polynyas are rare events that occur in the middle of the Southern Ocean. They are often linked to changes in the ocean's saltiness, w

Humboldt Squid: Red Devils Of the Deep Sea

Image
Like many other squids, Humboldt squid is one of the fierce predators. These animals are one of the largest squids which have earned the name "jumbo squid". They come in packs from the deep waters after the sunset and hunt for their prey. Possess extraordinary eyesight, a razor-sharp beak, and eight tentacles which makes them catch the prey and tear them apart.  Humboldt squids are the powerful swimmers and the bioluminescence in their skin allows them to change colors. This kind of behavior allows them to communicate and display a warning to the others. Ability to light themselves in colors of red and white during aggressive have earned them the name "red devils". On a very rare case, the individuals attack the scuba divers who were diving in groups of Humboldt squid they were feeding. It has only predator i.e; sperm whales . The Humboldt squid can live only a single year, so they decimate populations of small fishes or smaller squid when they hunt. Durin

Movie Club: Deep Blue Sea

Searching for a cure to Alzheimer's disease, Susan McAlester along with a group of researchers experiment and harvest the brain tissue of genetically altered sharks. when the island facility backers send an executive to investigate the experiments. The regular procedure goes wrong and the over-sized sharks attacking the creators and outnumbering them. The team must fight back and stop them from escaping into the ocean and stop breeding. Even though the movie doesn't reach the standards, it has a lot of horrifying parts. One which is where Samuel L.Jackson got surprisingly eaten by the shark while speaking to the team. Here are some of the shots from the movie This science fiction thriller has been directed by Renny Harlin featuring Thomas Jake as Carter Blake and Saffron Burrows as Dr. Susan McAlester.
