    • 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 ...

    • Climate-controlled submarine landslides on the Antarctic continental margin 

      Gales, Jenny A.; Mckay, Robert M.; De Santis, Laura; Rebesco, Michele; Laberg, Jan Sverre; Shevenell, Amelia E; Harwood, David; Leckie, R. Mark; Kulhanek, Denise K.; King, Maxine; Patterson, Molly; Lucchi, Renata G.; Kim, Sookwan; Kim, Sunghan; Dodd, Justin; Seidenstein, Julia; Prunella, Catherine; Ferrante, Giulia M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-18)
      Antarctica’s continental margins pose an unknown submarine landslide-generated tsunami risk to Southern Hemisphere populations and infrastructure. Understanding the factors driving slope failure is essential to assessing future geohazards. Here, we present a multidisciplinary study of a major submarine landslide complex along the eastern Ross Sea continental slope (Antarctica) that identifies ...

    • Pleistocene depositional environments and links to cryosphere-ocean interactions on the eastern Ross Sea continental slope, Antarctica (IODP Hole U1525A) 

      King, Maxine V.; Gales, Jenny A.; Laberg, Jan Sverre; Mckay, Robert M.; De Santis, Laura; Kulhanek, Denise K.; Hosegood, Phil J.; Morris, Antony; IODP Expedition 374, Scientists (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-22)
      The repeated proximity of West Antarctic Ice Sheet (WAIS) ice to the eastern Ross Sea continental shelf break during past ice age cycles has been inferred to directly influence sedimentary processes occurring on the continental slope, such as turbidity current and debris flow activity; thus, the records of these processes can be used to study the past history of the WAIS. Ross Sea slope sediments ...
