A.
Indian Ocean subtropical gyre
The Indian Ocean subtropical gyre is a large, clockwise-rotating system of ocean currents in the southern Indian Ocean that plays a key role in heat transport, climate regulation, and marine ecosystems.
-
B.
Indian Ocean Central Water
Indian Ocean Central Water is a mid-depth water mass in the Indian Ocean characterized by relatively uniform temperature and salinity, formed through subduction and mixing in subtropical regions.

Atlantic Meridional Overturning Circulation
The Atlantic Meridional Overturning Circulation is a large-scale system of ocean currents that transports heat and salt through the Atlantic, strongly influencing regional and global climate.
-
D.
Southwest Indian Ocean
The Southwest Indian Ocean is a region of the Indian Ocean off the southeastern coast of Africa, known for its strong western boundary currents, complex eddies, and significant role in global ocean circulation and climate.
-
E.
