High Resolution Middle Eocene Marine Stable Isotope - Southern Ocean Sites
Entry ID: UCSC_EoceneOligocene_31

Abstract: A prominent middle Eocene warming event is identified in Southern Ocean
deep-sea cores, indicating that long-term cooling through the middle and late
Eocene was not monotonic. At sites on Maud Rise and the Kerguelen Plateau, a
distinct negative shift in d18O values (~1.0‰) is observed ca. 41.5 Ma. This
excursion is interpreted as primarily a temperature signal, with a transient
warming of 4C ... View entire text
