Deepwater Horizon Trajectory Maps: By Type

On this page, you can download the trajectory maps produced by NOAA's Office of Response and Restoration (OR&R) during the response to the Deepwater Horizon oil spill in 2010. These maps are provided in zipped folders of PDF files, grouped by the type of map produced. [Need help with zipped files?]

The maps available here are more fully described on the Trajectory Map Background page. Also available on that page are publications we created to help you understand and interpret the oil trajectory maps.

Cumulative Trajectory Maps

This folder contains PDF maps showing the surface location of spilled oil for several consecutive days, as well as a forecast for the following day.

Nearshore Surface Oil Forecasts

The Nearshore Surface Oil Forecasts were forecast estimates for the nearshore location of oil for the next 24, 48, or 72 hours. During certain periods of the response, these maps were produced twice a day. The file name for each map contains the type of map; the outlook (24, 48, or 72 hours); and the date and time it was created, using the 24-hour time system*. For example, the map named N-Shore24_2010-05-08_2100.pdf shows the nearshore surface oil forecast for 24 hours, created on May 8, 2010 at 2100.

Offshore Surface Oil Forecasts

The Offshore Surface Oil Forecasts were forecast estimates for the offshore location of oil for the next 24, 48, or 72 hours. The file name for each map contains the type of map; the outlook (24, 48, or 72 hours); and the date and time it was created, using the 24-hour time system*. For example, the map named O-Shore48_2010-05-19_1800.pdf shows the offshore surface oil forecast for 48 hours, created on May 19, 2010 at 1800.

Loop Current Location Relative to Oil Slick

This folder contains PDF maps that provided daily updates on the location of the Loop Current and its major eddies, and the location of floating oil relative to the Loop Current system.

 


* In the 24-hour time system, time of day is indicated by four digits, the first two indicating the hour (00 to 23) and the last two indicating the number of minutes past that hour (00 to 59). Each day begins at midnight, 0000, and the last minute of each day is 2359. Under this system, 6:00 am is 0600, and 2:30 pm is 1430.
