Though you do get funky pressure effects on liquid freshwater released from deep subsurface ice shelf grounding lines and subsequently refreezing onto the base of the ice shelf as it floats up to lower pressures!

Though oddly the densest, deepest class of global water, Antarctic Bottom Water, is actually fresher than the overlying Circumpolar Deep Water or North Atlantic Deep Water!

They're typically used in thermodynamics when talking about changes along isopycnals, when obviously referring to density is unhelpful. They're not super common but a quick Google of ocean spice in scholar finds you a bunch of articles.

Basal melt at the deep back of ice shelves produces freshwater at depths >1000 m locally or more. This then flows up the underside of the ice shelf and becomes locally supercooled, leading to basal refreezing. Admittedly there are entrainment effects too, but a key driver is the pressure influence on the local freezing point. Ref: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2006JC003915
