The term "Dark Ocean" often refers to the vast, unexplored areas of the world's oceans that are deep and devoid of light. These regions, typically found below 200 meters, are home to unique ecosystems and species that have adapted to extreme conditions, such as high pressure and low temperatures. The lack of sunlight means that photosynthesis cannot occur, leading to a reliance on chemosynthesis and organic matter that sinks from above. Scientists study the Dark Ocean to understand its role in global climate regulation and biodiversity. Research in these depths can reveal insights into marine biology, oceanography, and even potential resources like minerals and biotechnology. The exploration of these areas is crucial for conservation efforts and understanding the impacts of climate change on ocean health.
