WebFirst, the timescale of deep convection in the ocean is sufficiently long that it may be modified by the Earth’s rotation; second, the convective process is localized in space so that vertical buoyancy transfer by upright, non-hydrostatic convection can give way to slantwise transfer by baroclinic instability in balanced, geostrophic motion ...

It does this by producing localized stress near the cluster margins, reminding one of the deep-focus earthquakes that were the very first evidence that subduction zones contribute to mantle convection.
