what type of water is in the ocean?
saline water
an ocean is a major body of saline water, and a component of the hydrosphere. approximately 71% of the earth's surface (an area of some 362 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. more than half of this area is over 3,000 meters (9,800 ft) deep. average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. though generally recognized as several 'separate' oceans, these waters comprise one global, interconnected body of salt water often referred to as the world ocean or global ocean. the deep seabeds are more than half the earth's surface, and are among the least-modified natural environments. the major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria: these divisions are (in descending order of size) the pacific ocean, the atlantic ocean, the indian ocean, the southern ocean and the arctic ocean.
natural environment
the arctic ocean has experienced drastic change over the years due to global warming. it has been known that the arctic ocean acidity levels have been increasing and at twice the rate compared to the pacific and atlantic oceans. the loss of sea ice has been connected to a decrease in ph levels in the ocean water. sea ice has experienced an extreme reduction over the past 30 years, forming a minimum area of 2.9×106 km at the end of the boreal summer of 2007, 47%, less than in 1980. sea ice limits the air-sea gas exchange with carbon dioxide. with less water completely exposed to the atmosphere, the levels of carbon dioxide gas in the water remain low. the arctic ocean should have low carbon dioxide levels due to intense cooling, run off of fresh water and photosynthesis from marine organisms. however, the decrease of sea ice over the years due to global warming has limited freshwater runoff and has exposed a higher percentage of the ocean surface to the atmosphere. the increase of carbon dioxide in the water decreases the ph of the ocean causing ocean acidification. the decrease in sea ice has also allowed more pacific water to flow into in the arctic ocean during the winter, this is called pacific winter water. the pacific water flows into the arctic ocean carrying additional amounts of carbon dioxide by being exposed to the atmosphere and absorbing carbon dioxide from decaying organic matter and from sediments.
