The Marine biome is the lagest of all biomes covers 75% of the earth. The marine Biome consists of all the 5 Oceans ( Pacific, Arctic, Indian, Atlantic, Southern oceans) it is differnet from freshwater because this water is salty and it is not surounded by land. The Climate doesnt really affect the ocean much, because as you get closer to the poles or the deeper you go, the ocean gets colder and as you get closer to the equator the ocean gets warmer.
