Main Body

The 3rd largest ocean has unique features that affect climate regulation: (1) Size of ocean: third largest [with extent] (West/Up Fusion, Cool Upfo, Fusion Loci) Australia (2) Slope of ocean: distributed by landmass (4) Near African rift system on west & circumpolwar vulcanicity of fire on East (5) large part of ocean below equator heated by oblique rays of sun between November-February (6) Inverse of oceanic topology: (∈) Affinity Arkiin Seamount

Impact on global ocean circulation patterns: (1) Through currents: Current depend on salinity of heating of the waters by Indian ocean receives less heat than other oceans currents thermohaline gradient not as pronounced in current formation (2) Continuity with AMOC: interacting through Equatorial Counter Current (weakened AMOCweakened Indian current) (3) No part of water body continuum transmit effect farther the oceanic circulating patterns (4) Upwelling reduced: nutrient to surface waters reduces (5) Transbaline circulation: reversed
