"The data used to create the spill image comes from the National Oceanic and Atmospheric Administration. NOAA releases a daily report detailing where the spill is going to be within the next 24 hours. They do this by collecting data from a number of sources, including satellite imagery and reports by trained observers who have made helicopter flights back and forth across the potentially affected areas. This data is entered into several leading computer models by NOAA oceanographers along with information about currents and winds in the gulf."
