abyssal depths
Deepest sea zones
The abyssal depths are the deepest regions of the ocean, where sunlight never penetrates and pressure is immense.
The phrase appears in both scientific and poetic contexts—marine biologists study creatures of the abyssal depths, while writers invoke them as symbols of the unknowable or terrifying: secrets buried in the abyssal depths of her past.
The term suggests not just depth but profound remoteness from ordinary experience.
