The container ship Margrethe Maersk, operated by the Maersk Line, steams toward California in May 2010. NOAA researchers and collaborators studied the ship's emissions in detail from a research aircraft (from which this photo was taken) and a research ship. The team found that as the container ship shifted to low-sulfur fuels and slowed down near the coast, air pollution emissions plummeted, with some pollutants dropping by as much as 90 percent.
