The land and water hemispheres of the earth, sometimes capitalised as the Land Hemisphere and Water Hemisphere, are the hemispheres on the Earth containing the largest possible total areas of land and ocean respectively.

Determinations of the hemispheres' centers vary. One determination places the centre of the land hemisphere at 47°13′N 1°32′W / 47.217°N 1.533°W / 47.217; -1.533 (in the city of Nantes, France).[1] By definition, the center of the water hemisphere is the antipodal point of the center of the land hemisphere, and is therefore located at 47°13′S 178°28′E / 47.217°S 178.467°E / -47.217; 178.467, near New Zealand's Bounty Islands.[1]

An alternative assignment determines the centre of the land hemisphere to be at 47°24′42″N 2°37′15″W / 47.411667°N 2.620833°W / 47.411667; -2.620833 (in île Dumet near Saint-Nazaire, France)[2][3]

The land hemisphere has just under seven-eighths of the land on the Earth, including Europe, Africa, North America, nearly all of Asia and most of South America. However, even in the land hemisphere, the ocean area still slightly exceeds the land area.

The water hemisphere has only one-eighth of the world's land,[1] including Australia, New Zealand, Antarctica, Hawaiʻi, the Maritime Southeast Asia, and the southern part of South America. Most of the Pacific Ocean and the Indian Ocean are on the water hemisphere. Proportionately, the water hemisphere is approximately 89% water, 6% dry land and 5% polar icecap.[1]
