Cancellation of the precessional cycle in δ18O records during the Early Pleistocene
Morée, Anne; Sun, Tianyi; Bretones, Anaïs; Straume, Eivind Olavson; Nisancioglu, Kerim Hestnes; Gebbie, Geoffrey (Journal article; Peer reviewed, 2021)The dominant pacing of glacial‐interglacial cycles in deep‐ocean δ18O records changed substantially during the Mid‐Pleistocene Transition. The precessional cycle (∼23 ky) is absent during the Early Pleistocene, which we ... -
Climate transition at the Eocene-Oligocene influenced by bathymetric changes to the Atlantic-Arctic oceanic gateways
Straume, Eivind Olavson; Nummelin, Aleksi Henrynpoika; Gaina, Carmen; Nisancioglu, Kerim Hestnes (Journal article; Peer reviewed, 2022)The Eocene–Oligocene Transition (∼33.9 Ma) marks the largest step transformation within the Cenozoic cooling trend and is characterized by a sudden growth of the Antarctic ice sheets, cooling of the interior ocean, and the ... -
Global Cenozoic Paleobathymetry with a focus on the Northern Hemisphere Oceanic Gateways
Straume, Eivind Olavson; Gaina, Carmen; Medvedev, Sergei; Nisancioglu, Kerim Hestnes (Journal article; Peer reviewed, 2020)The evolution of the Northern Hemisphere oceanic gateways has facilitated ocean circulation changes and may have influenced climatic variations in the Cenozoic time (66 Ma–0 Ma). However, the timing of these oceanic gateway ...
