Exploring All Arctic Images in SEAICEBOX:

Above you will see the current daily image of sea ice in the Arctic. You can use the drop down menu below the thumbnail image to select and explore any month's average sea ice in the database going back to 1979. To the right of the first thumbnail image you will see a second drop down menu. Here you can select a second image for comparison. Once you have selected the second image you will be able to select a third image for comparison. You can compare any three months sea ice conditions at a time going back to 1979.
