What Does PSU Stand For?
PSU stands for Practical Salinity Units
Practical Salinity Units (PSU) is a dimensionless unit of measurement used to quantify the salinity of seawater. It is based on the ratio of the conductivity of a water sample to the conductivity of a standard potassium chloride solution at a specific temperature. PSU provides a standardized way to express salinity, facilitating comparisons across different studies and regions while enhancing the understanding of oceanographic processes.
