This is clearly due. The ocean is clearly demarked powerfully by the circumpolar antarctic current that acts as a real physical barrier and as a heat exchanger with the rest of the globe.
I have also posted that we need to identify more sub - continants as well. just China is a great example and so is Indonesia and Malayia.. Or separately SE Asia and the South China Sea. ypou can see the point as these geographic units are bounded naturally in some manner and internally influence all components.
Otherwise we all need to recall that the Pacific is literally the surface of one half of the world. It was even once larger.

Earth 'officially' has FIVE oceans!
National Geographic finally recognises Antarctica's Southern Ocean on its maps alongside the Atlantic, Pacific, Indian and Arctic
The society announced their new mapping policy yesterday on World Ocean Day
Unlike its peers, the Southern Ocean has been defined by the current around it
Other oceans like the Atlantic are defined by the continents that bound them
The status of the Southern Ocean remains a contested issue on the world stage
National Geographic hopes its change will encourage conservation of the ocean

Cartographers at the National Geographic have finally recognised Antarctica's Southern Ocean on their maps, bringing their count of Earth's oceans to five.
The society — which has been releasing maps of the world since 1915 — publicly announced their new policy yesterday, to coincide with World Ocean Day.
National Geographic have defined the ocean as being bound by the current that flows around Antarctica — with a northernmost reach up to the 60th parallel south.
The Southern Ocean joins the Arctic, Atlantic, Indian and Pacific on their charts, although the Antarctica-encircling body's status remains internationally contested.
Nevertheless, National Geographic hope their revised maps will help people think differently about the Southern Ocean, thereby encouraging its conservation.

'The Southern Ocean has long been recognized by scientists,' explained National Geographic Society geographer Alex Tait in the announcement.
'But because there was never agreement internationally, we never officially recognized it. It’s sort of geographic nerdiness in some ways,' he added.
'We’ve always labelled it, but we labelled it slightly differently [than the other oceans]. This change was taking the last step and saying we want to recognize it because of its ecological separation.'
