Why we know so little about the Earth's ocean
Why we know so little about the Earth’s ocean

Why we know so little about the Earth’s ocean. Despite covering more than 70% of the Earth’s surface, the ocean remains one of the least explored and understood environments on the planet. There are several reasons why we know so little about the ocean:

  1. Depth and pressure: The ocean is incredibly deep, with the deepest point in the world’s oceans, the Challenger Deep, located in the Mariana Trench, reaching a depth of almost 11 kilometers. At such depths, the pressure is immense, making it difficult for humans to explore using traditional methods.
  2. Size: The ocean is vast, covering more than 361 million square kilometers of the Earth’s surface. This makes it a daunting task to explore and study comprehensively.
  3. Inaccessibility: The ocean is a hostile environment for humans, with extreme temperatures, strong currents, and storms making it difficult to access and explore. This means that much of the ocean remains largely unexplored, particularly in remote areas and deep underwater.
  4. Cost: Ocean exploration is expensive, requiring specialized equipment, ships, and personnel. Funding for ocean research is often limited, and this has hampered efforts to explore and study the ocean in more detail.
  5. Technology limitations: Until recently, technology has also been a limiting factor in ocean exploration. Many instruments and tools used in ocean exploration are relatively new, and advances in technology have only made it possible to explore deeper and more remote areas in recent years.

Despite these challenges, there have been significant advances in ocean exploration and research in recent years. New technologies, such as unmanned vehicles, underwater drones, and deep-sea submersibles, are making it possible to explore deeper and more remote areas of the ocean. Additionally, international efforts, such as the United Nations’ Decade of Ocean Science for Sustainable Development, are seeking to enhance our understanding of the ocean and its role in the Earth’s ecosystems, economy, and climate.
