Streaks of bright blue and green along Namibia’s western shores show where sulfur is rising to the surface of the Atlantic Ocean. The yellowish clouds of sulfur come from hydrogen sulfide gas produced by anaerobic bacteria (bacteria that can live without oxygen) at the ocean floor. As the gas wells up to the surface, it reacts with oxygen in the upper layers of the ocean and produces pure sulfur. In the first stages of the reaction, the sulfur appears white, and in this image creates a milky-green green tinge to the water. When the transformation is more complete, the plume will look very green. The yellowish sulfur and the blue water combine to make green swirls in the waters off of the Namib Desert coast of South Africa.

The hydrogen sulfide gas is highly toxic to fish. Periodic die-offs of whole populations of fish and other commercial seafood are ongoing concerns for the regional fishing industry. This true-color Aqua MODIS image was acquired on February 26, 2004.
