  • Major Nutrients and Oxygen

    Nitrate, Phosphate and Silicate are the major nutrients of economic importance to phytoplankton growth and consequently to primary production in the marine environment.  An adequate amount of these nutrients enhances primary production which supports the entire life within the ecosystem. Monitoring of these nutrients can also give an indication of the health status of the marine ecosystem.  Excessive algal growth forming blooms can be traced to excess nutrients.  Oxygen gives an indication of biological activity as it is produced during photosynthesis and utilized by organisms during during respiration.  A fair amount of oxygen is needed to ensure both primary and secondary production takes places. Lack of oxygen can create anoxic conditions with its detrimental effects on both plants and animal life in the marine environment.
