Are there ocean deserts? Are there parts of the ocean that never or rarely receive rain?

Not only are there sections of ocean that don't receive much rain, but there are also massive circulations called gyres. Gyres are basically huge portions of ocean that are surrounded on all sides by currents, so you end up with a rotating central section that is fairly stagnant. Water evaporates from gyres, but doesn't recirculate well with the rest of the ocean, which increases salinity and decreases nutritional components in the water.

What results can be described as something similar to a desert on land. A warm, salty, nutrient-poor area, where life is typically more scarce than in the surrounding areas.
