- Sea Water: Properties & Composition
Composition: Primarily water (
) and dissolved salts (Sodium Chloride -
is main salt).
Salinity: Concentration of dissolved salts, measured in parts per thousand (ppt).
Increases by: Evaporation, freezing (ice formation).
Decreases by: Precipitation, river runoff, melting ice.
pH & Ocean Acidification: Sea water is slightly alkaline (pH 7.5–8.4). Increased
dissolves in water, creating carbonic acid, reducing pH.
Density: Affected by temperature (cold = denser) and salinity (saltier = denser).
Vertical Structure:
Light: Penetrates top 200m (photic zone).
Temperature: Decreases with depth (thermocline).
Pressure: Increases by 1 atmosphere every 10m depth.
