A change in ocean circulation makes for long glacial periods through the Mid-Pleistocene Transition

Isotope records from the Southern Ocean imply that prolonged epochs of time between glacial and interglacial periods through the Mid-Pleistocene Transition were caused by a reduction in deep waters mixing with the surface and the positive feedback it created with the salinity gradient.
