Strong transport and mixing of deep water through the Southwest Indian Ridge

J. A. MacKinnon , T. M. S. Johnston & R. Pinkel

The Indian Ocean harbours an important but poorly understood part of the global meridional ocean overturning circulation, which transports heat to high latitudes. Understanding heat exchange in the Indian Ocean requires knowledge of the magnitudes and locations of both meridional deep-water transport and mixing, but in particular the latter is poorly constrained at present.
