Icebergs near Greenland melted thousands of years ago, and the water produced was of a different temperature and salinity than the surrounding seawater.
This difference kept the water separate as it sank to the ocean floor; it now circles Earth every several thousand years. The Natural Energy Laboratory of Hawaii Authority (NELHA), at Keahole Point, Hawaii, provides access to this deep seawater through a pipeline reaching 3,000 feet (914 m) into the ocean. Entrepreneurs have begun bottling the desalinated water, mainly to be sold in the Japanese market.
Kona Deep is an example of a bottled deep-sea water.
