What color dots represent the ships? [Hint: read paragraph below map] What color dots represent buoys? What do the purple dots represent?

These are REAL ships and REAL buoys all reporting a wide range of atmospheric and oceanic data back to the United States through the Internet. The flags on the dots represent the wind speed and direction at that location (see bottom of map page for further explanation). The contour lines represents lines of constant pressure.

Note the time and date stamp right above the map. How current is this information?

Note that there is a four- or five-character code at the bottom right corner of each ship dot. This is called the Ship ID Code and is unique to each ship.
