Starting in the middle Miocene (ca. 15 Ma), major ice-sheet expansion in Antarctica triggered a series of causeand-effect mechanisms that profoundly altered Earth's oceans and climate. This event marks the onset of longterm cooling in the late Cenozoic that is still ongoing. From ca. 14 Ma to the preindustrial period, global mean annual temperatures decreased by about 7°C (Burke et al., 2018;Gulick et al., 2017;Shevenell et al., 2004) and average CO 2 atmospheric concentrations decreased by more than half (Sosdian et al., 2018). The reasons behind this late Cenozoic long-term cooling are still under intense debate, however, it is clear that the persistence of Antarctic glaciation over the last 15 Myr would have not been possible without the establishment of deep oceanic basins around Antarctica, which enabled the formation of circumpolar circulation in the Southern Ocean and isolated continental Antarctica from warmer equatorial currents (Holbourn et al., 2005). Circumpolar circulation in the Southern Ocean initiated with the opening of the Drake Passage at ca. 49 Ma (Lagabrielle et al., 2009) and the opening of the Tasman gateway in the earliest Oligocene at ca. 33.5 Ma (Scher et al., 2015). Continued seafloor spreading finally aligned the Tasman gateway with the Westerly Winds at ca. 30 Ma, enabling the development of full clockwise circumpolar circulation around Antarctica (Scher et al., 2015). This establishment of circumpolar circulation across the Southern Ocean was also accompanied by increased production of Antarctic Bottom Water (AABW) in the deep ocean cell (Sykes et al., 1998). The equatorward movement of southern-derived bottom waters through deep-ocean tectonic gateways enabled the transport of cold and saline waters formed near the Antarctic shelves toward lower latitudes, which thus initiates the global thermohaline circulation (Liu et al., 2005). As tectonic reconfiguration of the Southern Ocean enabled circumpolar circulation to develop since the Oligocene, the tectonic evolution of deep-sea gateways in the Southern

“…International Ocean Discovery Program (IODP) Expedition 369 recovered sediments from the Great Australian Bight and Mentelle Basin in the southeast Indian Ocean (Figure F1). One of the main reasons for drilling the Expedition 369 sites was their high paleolatitude (60°-62°S) position, which allowed the sampling of high-latitude successions that are important for a reconstruction of the dynamics of the Cretaceous greenhouse climate system (Huber et al, 2019). Cenomanian to Turonian radiolarians from this part of the Cretaceous world have only been described in a single study so far that documented some specimens from Deep Sea Drilling Project (DSDP) Site 258 (Riedel and Sanfilippo, 1974).…”
