Metre sea water (msw or mS) is a unit of measurement used to express the density of seawater, particularly in the context of oceanography. It is defined as the equivalent depth of seawater that exerts a specific pressure at a given depth. The term is often used when dealing with hydrostatic pressure calculations or when discussing the buoyancy and density of water in marine environments.
