← GeographyWhich outcome occurs in fjord ecosystems because intensified glacial melting?
A)Stratified water column stability increases✓
B)Decreased sediment influx from rivers
C)Strengthened deep-water oxygen replenishment
D)Reduced frequency of freshwater pulses
💡 Explanation
Increased glacial meltwater intensifies the halocline due to decreased salinity, therefore increased stratified water-column stability reduces vertical mixing rather than promoting oxygen replenishment. Stratification increases because significant volumes of fresh water flow on top of salt water.
