What was the link that showed how much of the Baltic Sea was frozen?

Ice cover isn't far off normal at the moment.

It doesn't seem to say what range of years the "normal" cover is

Reading down normal is averaged over the years 1965 to 1986. A strange
period to use but I'm sure they have a reason why!
