The Oligocene–Miocene Boundary – Antarctic Climate Response to Orbital Forcing
Recent high-resolution Oligocene–Miocene oxygen isotopic records revealed a AU:2 relatively transient, ca. 2 myr period, 1 m amplitude cyclicity in isotopic values (Oi and Mi events, respectively). Intriguingly, it has been suggested that these isotopic excursions in oceanic d 18 O were linked to ep...
