← GeographyWhich process hinders complete fjord mixing under ice?
A)Halocline development strengthens water stratification✓
B)Increased glacial flour causes light absorption
C)Reduced oxygen diminishes biological activity
D)Thermokline inhibits deep water convection
💡 Explanation
Halocline development increases with freshwater input, which strengthens stratification because density differences inhibit vertical mixing. This prevents full overturning within the fjord, therefore the deep basin remains isolated rather than being fully oxygenated.
