A modern analog for the ancient sulfidic ocean? (Upper) Mahoney Lake, British Columbia, Canada—perhaps like the Proterozoic ocean (2)—contains abundant H2S in the photic zone. In the case of Mahoney Lake, the O2–H2S interface is only 7 m deep—ideal conditions for anoxygenic photosynthesis. (Lower) A “plate” of profuse purple, S-oxidizing, anaerobic bacteria at this interface generates more than half of the primary production in the lake. (Lower photo by J.
