Though the Southern Ocean does not have a landmass bordering it to the north, it is treated as a separate oceanic division due to the difference in water properties of the ocean south of the 60Â° S latitude. Some estimates suggest that its area is around 155 million square kilometers. In addition to these oceans, they also described many other smaller bodies of salt water including seas, bays, and estuaries. Then there is … Sign up for our science newsletter!
