The effect of the North Atlantic Subpolar Front as a boundary in pelagic biogeography decreases with increasing depth and organism size
Highlights: • The Subpolar Front is distinct along its northern edge but to the south it forms a more diffuse zone. • North-south water-mass hydrography is strongest down to depths of 500–800 m. • The frontal biogeographic signature is strong near the surface but decreases with greater depth. • This...
