Abundance and distribution of seamounts in the Azores

We characterized the seamount distribution of the economic exclusive zone (EEZ) of the Azores (Portugal) using 2 bathymetry datasets. Our algorithm showed that peaks and seamounts are common features in this region of the North Atlantic. The density obtained of 3.3 peaks of all sizes per 1000 km 2 is in the same order of magnitude as that obtained on the Mid-Atlantic Ridge by a few other studies. A total of 63 large and 398 small seamount-like features are mapped and described in the Azorean EEZ. Our distribution of seamounts predicts that about 57% of the potential Azores seamounts lie in the zone protected from deep-water trawling by European Commission Council Regulation No. 1568/2005.
