Enhanced deglacial carbon transport by Pacific southern-sourced intermediate and mode water

This study documents the deglacial intensified northward flow of high pCO2 Antarctic Intermediate and Mode Water in the Pacific Ocean and provides support for these water masses as one important conduit for oceanic outgassing in the eastern equatorial Pacific upwelling.

Mid-Pliocene climate change amplified by a switch in Indonesian subsurface throughflow

Tectonic activity severely restricted the seaway connecting the tropical Pacific and Indian oceans sometime between about 3 and 4 million years ago. Ocean temperature and salinity reconstructions indicate that the Indonesian Gateway reached its present configuration about 2.95 million years ago, leading to the cooling and freshening of subsurface water in the tropical eastern Indian Ocean.

Persistent summer expansion of the Atlantic Warm Pool during glacial abrupt cold events

In the high latitudes, abrupt cooling events are thought to control mainly the winter temperatures, thereby increasing seasonality. Sea surface temperature reconstructions from the Gulf of Mexico suggest that over the past 300,000 years these events also enhanced seasonality in tropical regions.

Mediterranean heat injection to the North Atlantic delayed the intensification of Northern Hemisphere glaciations

Subsurface heat transfer from the subtropical Atlantic Ocean to high latitudes during the mid-to-late Pliocene may have been responsible for a delay in the intensification of Northern Hemisphere glaciations, according to sedimentary proxy records and numerical modelling.
