潜点: Banco D. João de Castro

关于 Banco D. João de Castro

Banco D. João de Castro is a spectacular active submarine volcano nestled in the Atlantic Ocean, between the Azorean islands of São Miguel and Terceira. Its summit rises dramatically from depths of 1000 meters to just 12-13 meters below the surface, offering a truly unique diving experience. The last significant eruption occurred in 1720, briefly forming a temporary island before it succumbed to marine erosion. At the heart of the site lies a large crater, approximately 450 meters in diameter, with depths ranging from 12 to 25 meters. This caldera remains volcanically active, evidenced by extensive fumarole fields where gas bubbles, primarily carbon dioxide and hydrogen sulfide, escape from hydrothermal vents. This geological dynamism creates a surreal underwater landscape, showcasing the Earth's breath beneath the waves. Due to its remote, open-ocean location and nutrient-rich waters, Banco D. João de Castro attracts abundant pelagic life. Divers frequently encounter large schools of barracudas, bonitos, and amberjacks, alongside wahoos, devil rays, and sometimes loggerhead turtles. The crystal-clear offshore waters provide exceptional visibility, enhancing sightings of these impressive marine inhabitants. Access to this isolated seamount requires a boat trip of several hours, typically departing from Terceira. Diving here is best suited for experienced divers due to potential strong currents and its exposed position in the high seas. Descent lines are often used to manage these conditions, guiding divers into an unforgettable exploration of an active underwater world.
