The name comes from the bank's discovery in 1862 by HMS ...
The Porcupine Abyssal Plain is a vast, relatively level stretch of seabed with a depth range of 4,000 to 4,850 m (13,120 to 15,910 ft). It has a muddy floor in the abyssopelagic zone and scattered rocky abyssal hills that rise into the bathypelagic zone forming seamounts and knolls.
