Recently declassified satellite gravity data reveal bulges of unusually thick and elevated oceanic crust (red, yellow and green on the map) extending hundreds of kilometers from the Iceland and Azores hotspots. The two hotspots may be feeding huge supplies of magma to nearly the entire northern segment of the Mid-Atlantic Ridge.
