Seawater composition and properties: Properties of water ;Effect of dissolved salts in water;Salinity in the oceans (ions concentration, constancy of composition).

Light and sound: Light in the oceans (Absorption,Scattering, Visibility), Colour (algae, particulate matter, dissolved organic compounds), Electromagnetic radiation and remote sensing; Sound in the oceans: sound waves, speed of sound (Refraction and Sound channels), Applications of acoustic energy in the oceans (passive listening systems – hydrophones, Sonar, Sofar, Acoustic Profilers, Acoustic tomography).
