At a depth of 10,000 feet (approximately 3,048 meters) under the surface of the ocean, immense pressure is exerted due to the weight of the water above. This depth is part of the oceanic zone known as the bathyal zone, characterized by its significant darkness, cold temperatures, and high pressure environment.The pressure at this depth is quite staggering, reaching approximately 1,086 pounds per square inch (psi) or 750 times the atmospheric pressure at sea level.

To put it into perspective, imagine the weight of a small car pressing down on an area the size of your fingertip.The primary contributor to this pressure is the hydrostatic pressure, resulting from the weight of the water column above. Every additional 33 feet (10 meters) of depth adds another atmosphere (14.7 psi) of pressure. Thus, at 10,000 feet, the pressure is equivalent to around 320 atmospheres or 4,674 psi.Such intense pressure poses numerous challenges for any object or organism at this depth.

It necessitates specialized equipment and technology for human exploration, including submarines or remotely operated vehicles (ROVs). These vessels must be constructed with robust materials capable of withstanding the immense forces and preventing structural collapse.For marine life, surviving at these depths requires unique adaptations. Deep-sea organisms have evolved to withstand the extreme pressure, either through specialized body structures or adaptations that enable them to maintain internal pressure similar to their surroundings.

For example, deep-sea fish often have flexible bodies and gel-filled organs that prevent them from being crushed under the pressure.In summary, the pressure at 10,000 feet beneath the ocean's surface is incredibly high, exerting forces hundreds of times greater than atmospheric pressure at sea level. This extreme pressure creates a challenging environment for exploration and demands remarkable adaptations for the survival of marine life.


It is at these conditions that any rescue will be attempted and in this episode we take a look at where things currently stand with that effort as the submersible has rougly 12 hours of oxygen remaining.
