Unfathomable

The abyss is the zone of the ocean shallower about 20,000 feet.
As the deep sea has extremely low temperatures, this territory is characterized by its uniform environmental conditions.
This zone remains in perpetual darkness but I decided to use blue and light green tapes to reveal the cold climate.
I represent how sea ice is produced in this vital environment for Earth life.
Abyssal zone means bottomless but remains also an undiscovered surface.
