How much of the oceans have we discovered? Our Current Understanding
So how much of the oceans have we discovered? Well, our exploration of the ocean has revealed only a fraction of its vast expanse. Approximately 20% of the ocean floor has been mapped in detail, while the majority remains either unmapped or mapped with low resolution. This leaves a significant portion of the ocean largely unexplored and shrouded in mystery.
When it comes to our understanding of different ocean zones, scientists have classified them based on their depth and the amount of sunlight that penetrates their waters. These zones include the sunlight zone, twilight zone, midnight zone, abyssal zone, and the deep trenches.
The sunlight zone, also known as the euphotic zone, is the uppermost layer of the ocean where sunlight can reach. This zone extends from the surface down to about 200 meters. It is the most explored and studied zone, as it is relatively accessible and supports a great variety of marine life.
Below the sunlight zone lies the twilight zone, which ranges from about 200 to 1,000 meters deep. Here, sunlight is scarce, and the water becomes progressively colder and darker. While some exploration has taken place in this zone, our understanding of its unique ecosystems and biodiversity remains limited.
The midnight zone, also called the bathyal zone, stretches from around 1,000 to 4,000 meters deep. This zone is perpetually dark, with no sunlight reaching its depths. Explorations in this zone have been challenging, but technological advancements, such as remotely operated vehicles (ROVs) and deep-sea submersibles, have allowed scientists to gather valuable information about the organisms that inhabit this mysterious realm.
Beyond the midnight zone lies the abyssal zone, extending from approximately 4,000 to 6,000 meters. The conditions in this zone are extreme, with intense pressure and near-freezing temperatures. Despite the harsh environment, some limited exploration has taken place using deep-sea robotic vehicles. However, much of the abyssal zone still remains unexplored.
Lastly, the ocean trenches represent the deepest and least explored areas of the oceans. These trenches, such as the Mariana Trench, can reach depths exceeding 10,000 meters.
