NOAA produced cumulative trajectory maps early in the Deepwater Horizon spill response. They showed on a single map the surface location of spilled oil for several consecutive days, as well as a forecast for the following day. As the area of water affected by the spill grew larger, the forecast aspect of these maps became more important than the day-to-day changes in surface oil, so the next trajectory products included only forecasts. More information on trajectory maps is available at the Deepwater Horizon Trajectory Map Archive website.

Note:  During certain periods of the response, trajectory maps were produced twice a day. In the monthly lists, those maps are listed by date, with the time they were created (in the 24-hour time system). For example, the nearshore forecast maps (for the next 24 hours) produced on May 3 at 11:30 am and 11 pm are shown as "May 3 (1130) nearshore 24-hour surface oil forecast" and "May 3 (2300) nearshore 24-hour surface oil forecast," respectively.
