What Does AAIW Stand For?

AAIW stands for Antarctic Intermediate Water

Antarctic Intermediate Water (AAIW) is a water mass that forms in the Southern Ocean, characterized by its relatively low temperature and salinity compared to surrounding waters. It typically resides at depths of approximately 500 to 1,500 meters and plays a crucial role in global ocean circulation and climate regulation. AAIW contributes to the movement of nutrients and influences marine ecosystems, serving as a vital component in the thermohaline circulation and overall oceanic health.
