The ocean that has high salt content will be less likely to support marine life. Even the plants cannot grow if there is too much salt in the soil. The most dominant extracellular electrolyte is sodium chloride.
Marine is another word for ocean or sea - marine organisms live in the ocean.
The only parts of the ocean that cannot support life are those without or with depleted levels of dissolved oxygen (anoxyic). There are some bacteria that live in these places, but not multicellular life. All other ocean zones have life, though in different degrees of intensity. Obviously a coral reef has more life and more species than a benthic (deep water) trench, but there is abundant specialised life in the benthic zones, regardless.

Antarctica is the continent least likely to experience tropical storms. This is because tropical storms require warm ocean temperatures to form and Antarctica's temperatures are generally too cold to support their development.
The ocean is not aquatic, it is marine. Aquatic is freshwater. Marine is saltwater.
Marine means of or pertaining to the sea. So you can find things marine in the ocean or at places that have things to do with the ocean.
