    • 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 ...

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

      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 ...
