Solomon Islands (alkaline hydrothermal vents)

Solomon Islands' alkaline hydrothermal vents are underwater geological formations where heated, mineral-rich water escapes from Earth's crust into the ocean at relatively mild temperatures and high pH levels. Unlike volcanic vents, these are characterized by their alkaline (basic) nature, creating unique environments that support diverse microbial life and unusual ecosystems. The vents contribute to global geochemical cycles and offer insights into early life origins and potential extraterrestrial habitats. Located around the Solomon Islands in the Pacific, these vents are important for scientific research into marine geology, chemistry, and extremophile organisms.
