The two fjords Ísafjarðardjúp and Eyjafjörður are twin fjords. The shape is identical and their openings are on the same latitude.
It can be shown how the fjords have rotate around identical points 3° of longitude apart.

The direction of the vectors from the point of rotation is the same as the calculated value of convection cells at 66°N, that is N33°E and N33°W. The rotation angle of Eyjafjörður compared to Ísafjarðardjúp is 22°, the same as the difference between equatorial and polar convection rolls alignment at the latitude.
A coincidence of this degree of mathematical coherence is virtually impossible.

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog.
