What causes the golden haze over the Indian Ocean?

Why is the Indian ocean polluted?
Heavy rainfall (usually during India's monsoon season) around the many rivers flowing into the Indian ocean are the main cause. When flooding occurs, many types of debris both man-made and natural flow into the rivers, which then flow to the ocean. Additionally, many of the more remote areas in India do not have proper trash pick-up, or covered dumpsites, which adds to the problem. A very interesting study was done by Ramamthan in 1999 about the Indian ocean (See "indian Ocean Experiment" by Scripps Institute of Oceanography). Scientists found that there was a huge cloud of air pollution over the northern Indian ocean. They describe it as "a thick, brown haze", extending in some areas up to 3 km above the surface of the ocean. They studied the polluted matter to determine the cause and composition of the pollution. They found aerosols, soot, sulfates, nitrates, and mineral dust among other things. In short, the haze was mostly from partially burned fuels.
