Mission Accomplished

WHOI chemical engineer Richard Camilli (top right) shakes hands with pilot Konstantinos Katsaros, as he emerges from the submersible Thetis of the Hellenic Center for Marine Research. Camilli and Katsaros made a successful dive to investigate hydrothermal vents near the flanks of a volcano at the island of Milos (off Greece), while making the first ever deployment of a mass spectrometer on a submersible. Camilli’s miniature mass spectrometer “Gemini” (black canister on the upper part of the sub) can detect and measure multiple chemicals rising from previously undetected seeps and hydrothermal vents, revealing their locations.
