Europe's Grand Canyon: Nazaré Submarine Canyon

The Nazaré submarine canyon extends ~ 210 km westward from the coast of Portugal, down to a water depth of > 4500 m. The considerable habitat heterogeneity found throughout the canyon is affected by strong currents and high turbidity, especially in the upper parts of the canyon. The canyon morpho...
