Ocean chemistry and deep-sea sediments

Dissolved constituentsAfter being introduced to particulatematter occurring in oceans we nowlearn about dissolved constituents inoceans.NitratenonconservativeSodiumConservativeBariumnonconservativeMajor constituents are those having aconcentration > 1x 10 -6 by weight.Salinity for example has 35 parts perthousand weight. The majority has aconservative behaviour.Minor and trace constituents have only 1x10 -9 by weight, and nearly all of themhave a non-conservative behaviour.
