There are areas of some oceans that are devoid of life but there are no deserts in oceans.
Life first evolved in oceans because they provided a more stable environment with abundant nutrients and protection from harsh conditions on land. The oceans offered a conducive setting for the development and diversification of early life forms before some of them eventually transitioned to land.
This is unknown, but unlikely. The clouds of Venus are intensely hot, and filled with sulfuric acid. If any Venusian (Venerian? Venereal? Cytherian?) life forms exist, they are unlikely to be "life as we know it". However, there are Earthly life forms, cyano-bacteria, which live in the deep oceans, next to the sulfuric, volcanic vents on the sea floor. If any Earthly life could exist on Venus, that's probably it!
While carbon-based life forms are the most common on Earth, it is theoretically possible for non carbon-based life forms to exist. However, there is currently no evidence of such life forms on our planet.

After discovering non-carbon based life-forms at the deepest depths of our own planets' oceans, we are faced with the possibilty that life could exist on other planets even though they might or do possess atmospheres unsuited to the conventional carbon-based forms of life as we know them here on earth
There is no reason why a form of life doesn't exist on Mars. If life can exist in the very hot thermal vents deep in the earth's oceans, then why life in some form can't exist on another planet in some form?
Nope, it is far too hot for any life-forms to exist.
