Abyssal Plains

Abyssal Plains

Plotting my noon position on a large scale chart of the Eastern Pacific, I realized I was over an abyssal plain. Basically, the open ocean bottom is mostly dead flat and featureless. Growing up on the prairies, I know something about dead flat and featureless.

The open ocean, away from continental shelves is, on average about 4km deep. The depths of the deep open ocean are a seeming abyss and thus we have abyssal plain.
