An isopycnic surface is a surface of constant density inside a fluid. Isopycnic surfaces contrast with isobaric or isothermal surfaces, which describe surfaces of constant pressure and constant temperature respectively.
Isopycnic surfaces are sometimes referred to as "iso-density" surfaces, although this is strictly incorrect.
Isopycnic typically describes surfaces, not processes.
