We look at four different types of information from the buoys: surface air temperature, air pressure, distance, and speed. If you want to know more about why we look at that information, go to the Ice buoys section.
The ice buoys belong to the International Arctic Buoy Programme (IABP), and they provide the data we use here.
Clicking on each image of a plot will open the plot directly, and you can look at the individual buoy data there.
