Document Summary
Salinity: 3. 5% (per hundred) or 35%o (per thousand) (units) ppm, ppb: there are exceptions, fresh water, you aren"t going to find this right off the coast even though you are out in the ocean. Salinity: mostly sodium, chloride, also sulfate, magnesium, calcium, potassium, and bicarbonate. 0. 005 ppm: ppm (1,000,000) ppb (1,000,000,000, it would be 50 ppb. There are some that have extremely small concentrations: elements stay in sea water for a long time, not a lot enter and the ones that do stay for a long time, why the salinity is stable. How much money would we make from harvesting all the gold dissolved in the ocean: 251 trillion dollars dissolved in the ocean. Where does the salt come from: crust river vs. ocean water (mg, inland seas, excess volatiles earths mantle (mid ocean ridge, black smoker, plate tectonics had to come along first for us to figure it out.
