Ten years ago, Samer Naif made an unexpected discovery in Earth’s mantle: a narrow pocket, proposed to be filled with magma, hidden some 60 kilometers beneath the seafloor of the Cocos Plate.
Mantle melts are buoyant and typically float toward the surface — think underwater volcanoes that erupt to form strings of islands. But Naif’s imaging instead showed a clear slice of semi-molten rock: low-degree partial melts, still sandwiched at the base of the plate some 37 miles beneath the ocean floor.
