Exploring Deep-Sea Hydrothermal Vents and Chemosynthetic Life

Exploring Deep-Sea Hydrothermal Vents and Chemosynthetic Life

Discover the hidden world of deep-sea hydrothermal vents, where life thrives in chemosynthetic oases. Unlike photosynthesis, chemosynthesis uses chemical energy for the creation of organic matter, occurring where chemicals are released on the sea floor. These remarkable environments, first discovered in 1977, have transformed our understanding of life on Earth. Dive into the fascinating ecosystems at oceanic spreading ridges and convergent plate boundaries, found often at depths of 2km or more.
