Abyssal Zone - Woods Hole Oceanographic Institution
2024年5月2日 · The seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth is known as the abyssal zone, or the abyss. Sunlight doesn’t penetrate to these depths, so the waters here are extremely dark, and the animals that live here often use bioluminescence to communicate. The seafloor itself consists of large plains broken by ...

Hydrothermal Vents - Woods Hole Oceanographic Institution
2007年6月6日 · Hydrothermal vents act as natural plumbing systems that transport heat and chemicals from the interior of the Earth and help regulate global ocean chemistry. In the process, they accumulate vast amounts of potentially valuable minerals on the seafloor. So far, the difficulty of mining in deep water near fragile ecosystems and the relatively ...
