Document Summary
Implemented in the north pacific ocean, with acoustic transmissions from 1996 through fall. Viscosity of water is low, and decreases with increasing t. Easier for single-cell organism to stay afloat in cold water. In warm water, single-cell organisms need appendages to float. Important in water surface processes and drop formation. Evaporation and precipitation varies in a consistent manner w/ latitude. Total average oceanic salinity is about 35 g/kg. If the concentration of on of the major ions is known, any and all of the concentrations of other salts can be calculated. Na = 10. 76/19. 35 x 5 = 2. 78 g/kg. Trace elements occur in minute or trace amounts. Their concentration is parts per billion (ppb) ( g/kg or lower) Despite their low concentration, some are very important for life thriving in the ocean (iron, zinc, etc. ) Others may be considered pollutants (lead, mercury)
