    • Bottom current control on sediment deposition between the Iselin Bank and the Hillary Canyon (Antarctica) since the late Miocene: An integrated seismic-oceanographic approach 

      Conte, R; Rebesco, Michele; De Santis, Laura; Colleoni, Florence; Bensi, Manuel; Bergamasco, Alessandro; Kovačević, Vedrana; Gales, Jenny A.; Zgur, Fabrizio; Accettella, Daniela; de Steur, Laura; Ursella, Laura; Mckay, Robert M.; Kim, Seongjoong; Lucchi, Renata Giulia (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)
      In this paper we analyze how oceanic circulation affects sediment deposition along a sector of the Ross Sea continental margin, between the Iselin Bank and the Hillary Canyon, and how these processes evolved since the Late Miocene. The Hillary Canyon is one of the few places around the Antarctic continental margin where the dense waters produced onto the continental shelf, mainly through brine ...

    • Early and middle Miocene ice sheet dynamics in the Ross Sea: Results from integrated core-log-seismic interpretation 

      Perez, Lara F; De Santis, Laura; Mckay, Robert M.; Larter, Robert D.; Ash, Jeanine A; Bart, Phil J.; Böhm, Gualtiero; Brancatelli, Giuseppe; Browne, Imogen; Colleoni, Florence; Dodd, Justin P.; Geletti, Riccardo; Harwood, David M.; Kuhn, Gerhard; Laberg, Jan Sverre; Leckie, R. Mark; Levy, Richard H.; Marschalek, James; Mateo, Zenon; Naish, Timothy R.; Sangiorgi, Francesca; Shevenell, Amelia E.; Sorlien, Christopher C.; van de Flierdt, Tina; IODP Expedition 374, Scientists (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-11)
      Oscillations in ice sheet extent during early and middle Miocene are intermittently preserved in the sedimentary record from the Antarctic continental shelf, with widespread erosion occurring during major ice sheet advances, and open marine deposition during times of ice sheet retreat. Data from seismic reflection surveys and drill sites from Deep Sea Drilling Project Leg 28 and International Ocean ...

    • Simulated last deglaciation of the Barents Sea Ice Sheet primarily driven by oceanic conditions 

      Petrini, Michele; Colleoni, Florence; Kirchner, Nina; Hughes, Anna L.C.; Camerlenghi, Angelo; Rebesco, Michele; Lucchi, Renata Giulia; Forte, Emanuele; Colucci, Renato R.; Noormets, Riko; Mangerud, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-19)
      The Barents Sea Ice Sheet was part of an interconnected complex of ice sheets, collectively referred to as the Eurasian Ice Sheet, which covered north-westernmost Europe, Russia and the Barents Sea during the Last Glacial Maximum (around 21 ky BP). Due to common geological features, the Barents Sea component of this ice complex is seen as a paleo-analogue for the present-day West Antarctic Ice Sheet. ...
