Document Summary
Sea water conducts electricity and the conductivity is proportional to the amount of salt. Can be lowered on a wire or mounted on a buoy. The bending of light in water is proportional to the density. The saltier the water, the denser it is; hence, the greater the light refraction. Salinity (g/kg) = 1. 80655 x chlorinity (g/kg) 106 co2 + 122 h2o + 16 hno3 + h3po4 (ch2o)106(nh3)16h3po4 + 138 o2. Respiration (ch2o)106(nh3)16h3po4 + 138 o2 106 co2 + 122 h2o + 16 hno3 + h3po4. Photosynthesis and respiration effect concentrations of co2 and o2. C = 106/16 * 3. 00 = 19. 9 moll-1. Depth where there is as much oxygen produced by photosynthesis as consumed by respiration. Net change in oxygen/co2 concentration is 0! Organisms use respiration to consume oxygen, which outweighs oxygen production in deeper water. C = co2 - will not run o9ut. The compound that runs out first is the limiting factor for growth.
