Which flow regime results when glacial meltwater discharge increases within a fjord system?

💡 Explanation

When meltwater discharge increases, buoyant freshwater forms hypopycnal flow because it is less dense than saltwater creating a distinct fresh-salt interface. Therefore hypopycnal flow results, rather than downward hyperpycnal flow, thoroughly-mixed eddy diffusion, or baroclinic instability of a plume requiring significantly different density and saline interactions.
