Foraminiferal stable isotopes and physical properties from North Atlantic sediment cores for the past 3.2 million years, supplement to: Hodell, David A; Channell, James E T (2016): Mode transitions in Northern Hemisphere glaciation: co-evolution of millennial and orbital variability in Quaternary climate. Climate of the Past, 12(9), 1805-1828
We present a 3.2 Myr record of stable isotopes and physical properties at IODP Site U1308 (reoccupation of DSDP Site 609) located within the ice-rafted detritus (IRD) belt of the North Atlantic. We compare the isotope and lithological proxies at Site U1308 with other North Atlantic records (e.g., si...
