Sea surface temperature stack for the Brazilian margin from the Last Glacial Maximum to the Holocene

The number of sea surface temperature reconstructions from the Brazilian margin has grown through the last years, but with the surge of new records it has been turn difficult to explain individual data variability. In order to overcome this difficult and understant the evolution of surface temperature across the entire Brazilian margin from the Last Glacial Maximum to the Holocene, we propose a SST-stack based on Mg/Ca of surface-dwelling planktic foraminifera. The data display the temperature reduction during the LGM and the amplitude and timing of major SST increase across the last deglaciation. Interesting insights also emerge from the Holocene, with a SST decline from the late Holocene towards the present likely related to global volcanic activity. […]
