Which outcome occurs when a large iceberg melts within the relatively stable Western Pacific Gyre?

💡 Explanation

When an iceberg melts, it releases freshwater causing localized freshening because reduced salinity lowers water density that will resist mixing due to the gyre's relative stability, thereby inhibiting denser water formation. Therefore freshening results rather than increased upwelling, water mass formation, or weakened thermocline which require different forcing factors.
