The variation of seawater scattering with the salinity is a combination of two factors: decreasing contribution due to density fluctuation and increasing contribution due to concentration fluctuation, with the latter effect dominating. Surface tension is a property of liquids liquids have a limited ability – called surface tension - to resist an external force for example, when a liquid forms a lens-shaped meniscus in a graduated cylinder, the surface tension of the liquid is resisting the force of gravity.
