=Gases and Dissolved Solids in Ocean Water=

Most people believe that with water what you see is what you get, but this is not accurate. There are gases in the water of our oceans. These gases are Nitrogen, Carbon Dioxide, Oxygen and Methane ( in order from greatest to least percentage ). If you have studied the atmosphere ( air ) then you must have noticed these are the most common gasses in the atmosphere. This is because one of the sources for the gases in ocean water is the atmosphere along with methane from volcanoes, oxygen and carbon dioxide from life and various gases from rivers whose water flows into the ocean. There are also factors of the gasses, temperature can cause the particles of gases to either move very fast and let the gases escape or be very fizzy and trapped close together like the gases in a soda can when first opened. Depth, the farther you go into the ocean the less gases there, except if there is an underwater volcano. Water motion which is caused by rivers pouring in water or wind turbulance can add gases to the water. Lastly, proximity to the sources can cause more gasses to be in the water (air,life,volcanoes and rivers).

Dissolved solids, 3.5% of dissolved sloids make up the mass of ocean water. There are abundant elements in ocean water are ( greatest to least) Chlorine 55.0%, Sodium 30.6%, Magnesium 7.7%, Sulfur 3.7%, Calcium 1.2%, Potassium 1.1% Other 0.7%. Chlorine and Sodium are abundant because these are components of salt also there are trace elements which are elements in the ocean in very small amounts like Gold,Zinc and Phosphorous which are lockes away in nodules. (Check out the nodules page for more information) The sources of these elements are volcano eruptions, erosion and weathering of rocks and sedement and life itself.
