Water hemisphere
The Land and Water Hemispheres of Earth, sometimes capitalised as the Land Hemisphere and Water Hemisphere, are the hemispheres on Earth containing the largest possible total areas of land and ocean respectively. By definition (assuming that the entire surface can be classed as either "land" or "water") the two hemispheres do not overlap.
Determinations of the hemispheres vary slightly. One determination places the centre of the Land Hemisphere at 47°13′N 1°32′W / 47.217°N 1.533°W (in the city of Nantes, France). 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, near New Zealand's Bounty Islands in the Pacific Ocean.
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 (in île Dumet near Saint-Nazaire, France)
