Hello.
I've noticed a thing i could not understand, and hope someone can explain it to me.
Given: The sun at about 45* angle above, the calm sea flat below.
The sky is gray with thin, fog-like clouds.
There is a reflection in the sea of the sun above.

Now, let's look at it through a horizontally polarized filter:

There is an area, roughly 45* looking down, where the part of the reflection is bright and saturated blue.
Turning the filter 90 degrees, and there is nothing special:

Why is there the blue color?
As far as i understand, the light reflected from a border between two mediums with different indexes of refraction would be partially polarized perpendicularly to that surface, regardless of wavelength.
What else is at work here?
