In a recently published paper, Prof. Dr. Chiessi (P2L coordinator) and co-authors showed the first high-temporal-resolution sea surface temperature record for the Brazil Current spanning the last deglaciation. The inorganic geochemistry record shows high sea surface temperature anomalies during Heinrich Stadial 1, one of the longest and strongest slowdown events of the Atlantic meridional overturning circulation. This new dataset suggests that the Brazil Current was of paramount importance in propagating southwards the heat not transported to the North Atlantic during Heinrich Stadial 1. Moreover, based on organic biomarkers, the authors were able to produce a continental mean air temperature record for the Plata River drainage basin that shows a pCO2 pacing. Taken together, both records corroborate the notion that the long duration of Heinrich Stadial 1 was fundamental in driving the Earth out of the last glacial. For more details, please click here.
