Reykjanes(redirected from Reykjaneskagi)
a mid-oceanic ridge in the Atlantic Ocean. The Reykjanes Ridge extends for 1,350 km southwest of the Reykjanes Peninsula (Iceland), from which it got its name. Depths above the ridge are as great as 2,000 m; they decrease to 587 m above some peaks. At 53°N lat, the southwest end of the ridge is bounded by a transverse fault zone, south of which begins the North Atlantic Ridge.
