Isotopically depleted carbon in the mid-depth South Atlantic during the last deglaciation

  title={Isotopically depleted carbon in the mid-depth South Atlantic during the last deglaciation},
  author={A. C. Tessin and David C. Lund},
[1] The initial rise in atmospheric CO2 during the last deglaciation was likely driven by input of carbon from a C-depleted reservoir. Here we show that high resolution benthic foraminiferal records from the mid-depth Brazil Margin display an abrupt drop in dC during Heinrich Stadial 1 (HS1) that is similar to but larger than in the atmosphere. Comparing the Brazil Margin results to published records from the North Atlantic, we are unable to account for the South Atlantic dC data with… CONTINUE READING
