Salinity
Salinity is the measure of the concentration of dissolved salts in seawater. It is typically measured in parts per thousand (ppt) or practical salinity units (psu). Salinity affects the density and buoyancy of seawater, which in turn affects ocean currents and circulation patterns. It also plays a role in the freezing point and boiling point of seawater. Salinity levels can vary depending on location, depth, and climate. High levels of salinity can have negative impacts on marine life and ecosystems, while low levels can affect the growth and survival of certain species.
