First record of oceanic anoxic event 1d at southern high latitudes: Sedimentary and geochemical evidence from International Ocean Discovery Program Expedition 369
Oceanic anoxic event 1d (OAE 1d) has been well studied at northern low latitudes (i.e., in Tethys and the North Atlantic); however, the paleoenvironmental response associated with this event at high latitudes has not been documented and the trigger mechanism remains unknown. Here, we address both of...
