(1993): A search for an early Holocene CaCO3 preservation event. Paleoceanography, 8(3), 333-339, https://doi.org/10.1029/93PA00423 PB - PANGAEA DO - 10.1594/PANGAEA.729720 UR - https://doi.org/10.1594/PANGAEA.729720 N2 - The CO2 record for air bubbles from the Byrd Station ice core suggest a drawdown in the ocean-atmosphere carbon reservoir during the early Holocene. Such a drawdown would require a corresponding increase in the CO3= ion concentration in the deep sea. We report here the results of a search in Atlantic sediments for evidence that the lysocline showed a corresponding deepening. While both the pteropod and the calcite preservation records we have obtained are consistent with expectation, they are not conclusive. ER -
